Yoruichi Shihōin

is the former captain of the 2nd Division of the Gotei 13, as well as the former commander of the Onmitsukidō. Having abandoned her command of both, she works with Kisuke Urahara and Tessai Tsukabishi, based out of the Urahara Shop in the Human World.

Appearance
Yoruichi Shihōin is a dark-skinned woman with golden-colored eyes and long purple hair, which she keeps up in a ponytail. Her standard attire consists of a backless, black sleeveless undershirt, an orange over-shirt with two white straps on each shoulder, a large beige sash around her waist, black stretch pants and long beige wrist warmers, secured by bands, and long beige leg warmers with brown light shoes, allowing for stealth and easy use of Shunpo. She previously wore a beige neck warmer, which she pulled up to cover her face in order to hide her identity, but seems to have forgone its use. She, unlike any known Shinigami, is able to transform into a black cat for long periods of time. In this form, she has a distinctive male voice and golden eyes. 110 years ago when she was a captain, she wore the same sleeveless and backless Onmitsukidō uniform, with long black wrist guards that Suì-Fēng wears now, but had a black ribbon tied around her neck. She also wore a long-sleeved captain's haori. Her hair was also much shorter and cut in a style similar to Suì-Fēng's current hair-style but without the braids. At some point prior to this she wore the white Onmitsukidō uniform of the correction corps.

Personality
Yoruichi is intelligent and witty, holding an intimate knowledge of the Soul Society and its workings, as she was the former leader of the Onmitsukidō and the Second Division's captain. Although of noble birth, she acts differently from most other nobles, very much like Kaien Shiba. For instance, she instructed Suì-Fēng to refer to her without using honorific suffixes, but reluctantly settled for being called "Yoruichi-sama" ("Lady Yoruichi" in the dub). She also transforms into her human form directly in front of Ichigo on several occasions just to see his reaction to seeing her naked, which she even teases him about. Another note of her eccentricity is that she speaks in a dialect that elders use, such as identifying herself as "washi" (a term that usually old men define themselves with) instead of more feminine terms like "watashi" in both her human and animal forms (though specifically for the Japanese version).

Although relatively calm and mature when a situation calls for it, Yoruichi is quite laid-back and playful, often teasing or flirting with those younger than her, such as Ichigo Kurosaki at the underground hot spring, a younger and hot-headed Byakuya Kuchiki, Suì-Fēng before her time as a captain and Kisuke Urahara, childhood friend, former underling and fellow ex-captain. Yoruichi prefers to drink milk, which fits with her practice of transforming into a cat.

History
Yoruichi Shihōin was born the princess of the, The Shihōin family, one of the four noble families. Yoruichi grew up at the Shihōin Mansion in the Seireitei of Soul Society, with her childhood friends Kisuke Urahara and Tessai Tsukabishi. During this time they played together daily under the Sōkyoku hill training space, which Urahara built when they were children.

Later Yoruichi became the Corps Commander of the Executive Militia of the Onmitsukidō while serving as the 22nd generational head of the Shihōin family, the first woman to ever hold the position. Some time later she would serve as Commander-in-Chief of the Onmitsukidō as the position is traditionally held by the heads of the Shihōin family. She eventually rose to the position of Captain of the 2nd Division of the Gotei 13 further uniting the former separate military arms together as this was also traditionally done by her family. Sometime later she decided to change her direct role in the Onmitsukidō from being the Corps Commander of the Executive Militia, which is the position traditionally held by the Commander-in-Chief, to being the Corps Commander of the Corrections Corps. While Yoruichi was Onmitsukidō Commander, she took in Suì-Fēng as a personal bodyguard. Recognizing her talent she became a mentor and friend. She taught Suì-Fēng most of the techniques she knew. During her time in Soul Society, she created many techniques that involved Shunpo, as well as teaching some of them to Byakuya.

About 110 years prior to the current time Yoruichi recommended that Kisuke Urahara, her 3rd Seat, be appointed to the recently opened position of Captain of the 12th Division after the former Captain Kirio Hikifune was promoted. Prior to presenting Urahara with the news of the open position, Yoruichi had a sparring session with Urahara at the Sōkyoku hill training space. Before retiring back to the 2nd Division barracks, Yoruichi informed Urahara that she had recommended him for the position. Suì-Fēng confronted Yoruichi, concerned that she was overestimating Urahara's capabilities and proceeded to explain that she believed it had been a mistake to appoint him as Corps Commander of the Detention Unit. Suì-Fēng continued by stating that he was undeserving of such a position. While Yoruichi readily admitted to the fact that Urahara was not really a hard worker, she dismissed Suì-Fēng's criticisms and playfully insinuated that her focus on him must have romantic connotations, which Suì-Fēng denied. After spending the day following Urahara around Soul Society taking notes, Suì-Fēng returned to the 2nd Division barracks to show Yoruichi her evidence of Urahara's lack of competence in his position. Suì-Fēng arrived only to find Urahara already there talking with Yoruichi, she is then told that Urahara would be taking the captain proficiency exam, to which Suì-Fēng stands in disbelief. Yoruichi confirmed it and further requested that Suì-Fēng attend the exam as well. She explains that normally only captains are allowed to attend but that she has asked special permission to allow Suì-Fēng to attend. Suì-Fēng was at first confused about why she should attend but Yoruichi told her there was no need to keep secrets as she knew she was attracted to Urahara, which Suì-Fēng again denied. Yoruichi explained that she knew all about how Suì-Fēng had been following Urahara around all day. Suì-Fēng admitted that she was following Urahara around but told her it was to prove that he was lazy, incompetent, and not worthy of Yoruichi's praise. Suì-Fēng handed her notes to Yoruichi who read them and commented on how detailed they were. When Urahara didn't deny any of the information in the report Suì-Fēng was shocked that he would be so truthful to his seemingly unprofessional actions. Yoruichi, unsurprised, quipped that Urahara never changes and praised Suì-Fēng for her intelligence gathering skills. At first, Suì-Fēng was happy until she realized that Yoruichi regarded the notes not as intelligence information but rather as a love letter. Suì-Fēng was reasonably distressed and Yoruichi laughed it off and told her to loosen up as she wasn't serious. They were then interrupted by the arrival of a squad member who delivered a message that the people Urahara had been looking for had been found. Suì-Fēng replied that if he didn't return in time it would put a strain of the 2nd Divisions reputation as well as Yoruichi; which Yoruichi simply dismissed telling Urahara to hurry off to his duty and telling Suì-Fēng to come along to help prepare for Urahara's Captain's Proficiency Test.

Yoruichi is later seen among the other captains awaiting the start of the ceremony. Upon Urahara's arrival to the 1st Division barracks where he was formerly introduced to the other captains; he was chastised by Yoruichi for being so reluctant, as she told him that he was already a captain, so he should stand tall. A day or so after Urahara took over the 12th Division, Yoruichi was told by a Onmitsukidō member that Urahara had entered into the Detention Unit property with claims that he was previously given approval to go. Yoruichi couldn't seem to recall when or even if he asked for permission or whether she granted it; but when asked if she wanted him removed, she nonchalantly told her division members not to bother and to allow him to go where he liked. When asked if she had remembered the incident in question, Yoruichi plainly said no. Suì-Fēng became distressed and prepared to voice her disapproval, though Yoruichi told her to calm down as it was Kisuke they were talking about, stating he must have had an idea of some kind.

Yoruichi appeared to be on good terms with the members of the Kuchiki noble family as she would often visit the Kuchiki manor to play tag with a teenage Byakuya Kuchiki. On one such occasion, she was asked to train Byakuya by his grandfather Ginrei Kuchiki, the head of the Kuchiki family as well as the 6th Division captain. Upon seeing the arrival of Yoruichi, Byakuya swung his sword at her and called her a were-cat. Yoruichi laughed and playfully began to tease him, calling him 'Little Byakuya". She complained about such a greeting after she came all the way there to see him. Byakuya yelled at her saying that he didn't want to see the likes of her and that he would be the head of the Kuchiki clan soon enough, so he had no time to waste on her. While asking if that is the case she stole the ribbon holding his hair back. Byakuya quickly turned and swung his sword at her, but she easily dodged it. Yoruichi laughed at him and exclaimed that if the head of the Kuchiki clan could get his hair-tie stolen by a girl who is just playing, then the future of the Kuchiki Clan had become bleak, although this was just a ploy in order to entice him into another game of tag. Not to be defeated so easily, Byakuya told her not to move an inch, but before he could finish she told him that he couldn't catch her as she used Shunpo to begin the chase. Byakuya plainly stated that he could see that she wished to incite his wrath and he so promised to make her see the error of her ways, further making the claim that his Shunpo was far superior to the likes of hers.

9 years later Yoruichi is seen at an emergency meeting of the captains of the Gotei 13, where the Captain-Commander was giving an intelligence report on the unknown disappearances of the 9th Division captain Kensei Muguruma and lieutenant Mashiro Kuna as well as the other high ranking members of their division. Yamamoto stated they had previously been sent out to investigate the disappearance of other division members. He then declared he will choose 5 captains to form an investigation team. When a very winded and frantic Urahara showed up to ask that he be allowed to go with the investigation team as he had previously sent his lieutenant Hiyori to the sight of the disappearances, he was summarily told no by Captain-Commander Yamamoto. When he protested he was chastised by Yoruichi, who told him he was acting pathetic and that he should get a grip on himself. She further stated that he sent Hiyori himself, and that for him to lose his composure like that only insulted her. The Captain-Commander continued naming the members of the investigation team and told Yoruichi that she was to standby for further orders.

The next day, Urahara and Tessai were arrested under the orders of the Central 46 Chambers. It immediately became evident that they had been set up by Aizen, but were given no right to defend themselves and prove their innocence. As a result, they were quickly given their sentences. Urahara was sentenced to become human and to be exiled to the Human World for "committing crimes against researching and invoking forbidden phenomenon" as well as "deceiving and inflicting grievous injury to fellow Shinigami". Tessai was sentenced to life imprisonment in a Level 3 detention area for "using forbidden Kidō techniques." Before either of their sentences could be executed a masked Yoruichi entered the building knocking the guards unconscious and rescuing the disgraced former captains. Yoruichi brought them to a secret underground area.

In this secluded area, she berated them on how mad she was at them for excluding her from their plan. She also revealed that she had brought the eight Hollowfied Shinigami, along with the new prototype Gigai that Urahara was working on. With that epiphany, Urahara resolved to make ten reiatsu-blocking Gigai to aid him & Tessai. Tessai then stated his worry about Yoruichi's safety, but she calmly stated that they should not worry about her as she would escape somehow.

When she left Soul Society, she left behind her titles and positions and was thus relieved of her high status. She was succeeded as 2nd Division Captain and Commander of the Onmitsukidō by her protégé, Suì-Fēng, at a later date.

Agent of the Shinigami arc
Yoruichi makes her first appearance in feline form, where it is revealed to Jinta Hanakari by Tessai Tsukabishi to be Kisuke Urahara's best friend. Yoruichi is later sitting outside of Urahara's shop looking at the sky. When Urahara comes out he ask what is she looking at, Yoruichi shows to be no ordinary cat as it can talk and is seemingly male, Yoruichi tells him to stop acting as he knows fully well that 'they' have already come. After Rukia Kuchiki is taken back to Soul Society, Ichigo beings training with Urahara to regain his Shinigami powers. At the same time Yoruichi poses an offer to train Orihime Inoue and Yasutora Sado in the use of their powers, warning them that his lessons are strict and difficult. They readily accept. They then go to track down Uryū Ishida, who is somewhat surprised to see them, but Orihime explains that they must engage in training lessons if they are to go to Soul Society, to which Uryū poses the question regarding who their master will be. Orihime tells him, knowing he will be sceptical, that their trainer has been standing next to him the entire time. Uryū is surprised by explains that there can't be a human that stealthy. Yoruichi speaks up to tell Uryū that it is "he" who will be training them. Uryū predictably freaks out at the notion of a talking cat. After regaining his composure over the issue Uryū calmly states he can't believe that there is such a thing as a talking cat. Yoruichi tells him that the issue is not about "him" but about the necessary training in order to save Rukia from Soul Society. Though coming around to the idea, Uryū declines to train with them as he has plans of training on his own and rather than saving Rukia he just wishes revenge on the Shinigami who previously defeated him. Yoruichi resolves that he has no desire to go to Soul Society and that they must go and train before it is too late.

In an abandoned room, Yoruichi proceeds to train Chad and Orihime, but they can't seem to call on their powers. Yoruichi exclaims that at this rate no matter how long they train they can't go to Soul Society. "He" also comments on how if they can't find their powers and freely call upon them they are as good as dead trying to go there. "He" then urges them both to remember the first time their powers manifested. Then the conclusion to what they needed to do was reached. Their powers were activated when they were put in a position to protect others and that they should think back on what they were trying to protect at the time. It is through Yoruichi's words that Orihime comes to understand that she wishes to protect Ichigo and the realization brings forth her powers in the form of the "Shun Shun Rikka". Yoruichi then tells Orihime that the next thing she needs to learn is how to control her powers as they are now attacking "him". Yoruichi then turns "his" attention to Chad and asks him why he wishes to go to Soul Society. Shortly, Chad gains access to his powers and uses its ability to punch a huge hole in the wall much to Yoruichi's surprise. Both Orihime and Chad were happy to have gained free use of their abilities allowing them to go to Soul Society. Yoruichi tells them they have no time to celebrate, as they just damaged property and they needed to get out of there before they got into trouble.

Yoruichi decides to act as guide of the group as they prepare to go to Soul Society through Urahara's Senkaimon. Once Urahara explains to them the dangers of using the passage, Yoruichi comments that only those who know what their hearts think will be able to follow him, when Ichigo comments that everyone gathered has made the commitment to go, Yoruichi reminds Ichigo that if he loses then he will never return. Ichigo is firm in his resolve to win and Yoruichi is happy at his response. It is from this point that Yoruichi acts as a guide through the journey in the Dangai Precipice World, the space between Soul Society and the living world.

Soul Society arc
When they arrive in Soul Society an ungainly manner, Yoruichi then proceeds to inform them of the seriousness of the situation. When Ichigo asks whether they are in Soul Society, Yoruichi gives them an explanation of their surrounds. He states that they are in the outskirts, the Rukongai, the place where the souls live when they first come to the Soul Society. It's located around the Seireitei. Rukongai is the poorest and biggest free area, but it also holds the most souls. When Ichigo assumes that one of the streets looks like the place where the Shinigami would live, he runs toward it but Yoruichi screams at him to stop or he will end up dead. Ichigo moves out the way in time as huge wall falls down all around the Rukongai. It is here that Ichigo is stopped by a large giant of a man. When Ishida asks what manner of being he is, Yoruichi tells them that his name is Jidanbō, and he is one of the elites in Soul Society, as he is the guard of one of the four gates, the west gate, generally called the Seireimon Gate Guardian. Ishida deduces that if he is the guardian then they must get past him if they are to enter Seireitei, to which Yoruichi says that he is right but it won't be easy as in the past 300 years, no one has ever gotten passed him and that strength alone won't be enough to beat him. He then tells them that they must prepare a plan in order to pass this trial. Yoruichi then screams out for Ichigo to retreat and not to fight. Yoruichi is distressed to see that Orihime and Chad have decided to ignore him to stand at Ichigo's side. Yoruichi along with the others bear witness to Ichigo's unlikely amazing defeat against Jidanbō, after the defeat as per the rules Jidanbō allows Ichigo and his friends through the gate but is greatly surprised at an unexpected arrival.

Gin Ichimaru, the Captain of the 3rd Division arrives and promptly cuts off Jidanbō's left arm. Yoruichi realizes his mistake as he had not foreseen the arrival of a captain, he then notes that though Ichigo and his friends are powerful they have no idea that the strength of a captain. He realizes that if they confront him head on then the worst scenario will come to pass. When Ichigo attacks Gin head on Yoruichi yells at him what he thinks he is doing, he then yells at Ichigo that they must retreat before he can properly react he is pushed along with Jidanbō out the gate by Gin's Shikai.

When it is determined that Ichigo is alright, he apologies to Yoruichi for allowing the gate to close. Yoruichi plainly says that there is no point in feeling bad about it now. As even if the door is closed again, had they made it through the results would been the same as he would still have to face Gin, so in turn he should be happy that he is even alive. It is then that the souls that live in the Rukongai come out of their houses, when Ichigo and the others comment on who they are and if they were hiding all that time. Yoruichi explains that he can't blame them, as anyone who was not guided to Soul Society by a Shinigami is considered an intruder. As the circumstances would have it Ichigo and his friends would be considered trouble makers. As such the souls were hiding because they were afraid. When Ichigo asks if they are dangerous, Yoruichi deduces that since they are showing themselves before them they are probably not. While resting among the citizens of Rukongai, Yoruichi discusses his plan to enter into the Seireitei, but decides on entering another way without using the gate. When questioned about how he plans to get in without the use of the gate, Yoruichi then asks that Elder-Dono, the citizen whose house they are using, where he can locate Kūkaku Shiba. Noting that she is a drifter and that her place may not be in the same place as it was last. Elder-Dono is noticeably surprised as that would mean the 'alternative way' of entering the Seireitei was what Yoruichi was inferring to.

Yoruichi leads the group out into the open area outside of the village, exclaiming that Kūkaku's personality prefers open areas and solitude. Yoruichi tells the group that even though the location of the house changes constantly, the house is always the same style and that he will know at a glance. Not long after making the statement they come upon the house. Upon approach they are stopped by two twin guard/servants Koganehiko and Shiroganehiko, who refuse to allow them to pass, until they notice Yoruichi and allow them passage, from there they are taken down into the house where Kūkaku happily greets Yoruichi. The group is noticeably surprised that Kūkaku is a woman. Yoruichi immediately asks Kūkaku if she can help them. Kūkaku states she figured as much, since it is the same every time Yoruichi comes. Later, Yoruichi explains the situation and plan to Kūkaku who agrees to go along.

After undergoing the necessary training to use Kūkaku's Fireworks cannon to enter the Seireitei the group prepares to leave. Ichigo asks whether they will have to use the orb technique he learned to get through and then asks whether Yoruichi, being a cat, can achieve the same results. Yoruichi simply tells him to place the orb on the ground, to which he climbs on top of it of the orb and states that this sort of thing is like breathing to him as he seamlessly creates a barrier. Ichigo is disappointed at his lack of ability even further to which Yoruichi asks if he feels even more inferior now after training so hard to do something so easy for him to achieve. As Kūkaku prepares to shoot the group enters the cannon, while inside, Yoruichi tells them to not wander off by themselves and that if they encounter a captain-class enemy, they are to run, as their objective is to rescue Rukia and not to engage in any unnecessary risks. When they succeed in penetrating the barrier protecting the Seireitei the destabilization of the spiritual energy powered cannonball, caused the team to split and become separated in various parts of the Seireitei. As the team began to separate Yoruichi assures Ichigo that they will find a way to survive but first he must worry about himself. As the group broke up into four separate directions, with Yoruichi left all by himself but maintained that this way would probably be better. Yoruichi finds himself hurtling toward a group of waiting Shinigami, but he bounced back and onto the top of a nearby building.

Running around in cat form, Yoruichi keeps track of the progress of all of the others, rescuing Ichigo after his fight with 11th Division Captain, Kenpachi Zaraki. He takes Ichigo to a secret underground area where he can recuperate. Ichigo eventually wakes up and thanks Yoruichi for saving his life, but realizing the urgency of helping their friends he gets up too fast reopening his wounds some before Yoruichi pushes him back down and assures him they all are fine. He then comments to Ichigo that he needs to rest and if not for this mask he wore at his torso he would have sustained serious injury. Ichigo is left surprised at the broke hollow mask he has seen previously before. He then explains that he hadn't kept it that he had thrown it away. Yoruichi is surprised at this revelation and tells Ichigo that he will take it and dispose of it, but it Ichigo states that he wants to keep it, at this Yoruichi becomes angered and demands he gives the mask over to him. Yoruichi comments to himself that it is probably not possible but he better watch out for it just in case. He is sidetracked from his train of thought by Ichigo commenting on how strong he must be, and how he has ran around all this time without getting hurt and carrying him away with such a small body. To which Yoruichi explains that it was no real problem once he returned to his original form. Ichigo is surprised at the revelation of Yoruichi having another form.

Yoruichi then recalls that he has never shown Ichigo his true form. He resolves to show Ichigo and begins to transform revealing himself to truly be a female all along. Ichigo is left speechless, to which Yoruichi comments that she figures that he was surprised to find out that she was a female because he assumed the she was a male because of the sound of her voice in cat form. Yoruichi quips how she loves transforming into her true form as it always leaves everyone surprised. She then takes out an object and tells Ichigo that she will explain how she carried him there. Ichigo becomes frantic and tells her to put on some clothes. Yoruichi apologizes as it has been some time since she has worn clothes. She teases Ichigo about him being so innocent, asking if that was his first time he had ever seen a girl naked. He tells her to shut up, but she continues to poke fun at him by asking if he would like to see again as he doesn't know when the next time he'll see a naked woman, to which Ichigo tells her to mind her own business and they argue further about how he has no sense of humor. Yoruichi then shows him the object she used to get him to the secret underground area. She then tells him the function of the object and how to use it. She exclaims that it is a very unique item in Soul Society and that Ichigo should feel honored. Ichigo becomes curious and asks Yoruichi who she really is, but before she can answer they both feel an intense spiritual pressure, which Ichigo identifies as belonging to Byakuya Kuchiki Captain of the 6th Division. Ichigo immediately rushes off explaining to Yoruichi that he has to save Ganju and Hanatarō, as they went off in the direction the spiritual pressure is coming from. Ichigo takes out the artifact and uses it to get to his friends faster. An annoyed Yoruichi tries to stop him but he runs off anyway and she follows on foot.

Ichigo engages in battle with Byakuya, and Yoruichi arrives just in time to stop the release of Senbonzakura's Shikai, her arrival surprises both Byakuya and Jūshirō Ukitake, Captain of the 13th Division. Hanatarō asks Rukia if she knows who Yoruichi is, she says no but she has heard the name before. Byakuya notes that she is the former Commander-in-Chief of the Onmitsukidō and the former Corps Commander of the Correction Corps. Byakuya remarks how he hasn't seen her face in a long time, noting that it's been a hundred years since her disappearance and that everyone thought she was dead. Ichigo asks Yoruichi if she has came to save him and thanks her but tells her that he is determined to defeat Byakuya. Before Ichigo can react Yoruichi is in front of him and she impales him with her hand right into his bandaged chest wound. Ichigo tries to ask her what she is doing before passing out.

Ukitake comments that it is a drug, possibly either Gaten or Hōten, and by releasing a strong tranquilizer directly into his body she must be trying to save him. Yoruichi acknowledges Ukitake as Byakuya asks her if she thinks he would allow it, while he refers to her as 'Senpai'. He then comments that she won't be able to get away so easily. Yoruichi points out that Byakuya is talking big and asks him if he ever won even one game of tag against her. Byakuya asks to try again, starting another game of tag. Then the two engage in a test of speed using Shunpo with Yoruichi carrying an unconscious Ichigo while still staying a step ahead of Byakuya, though he was quickly gaining on her, expressing that she will never escape him with that level of Shunpo as he attacks her and cuts her across the chest with his blade. Before Byakuya realizes it was a decoy and that Yoruichi is perched upon his outstretched arm, while carrying Ichigo, Yoruichi remarks to him that he can't catch her with that level of Shunpo and she quickly moves to the top a nearby building and yells down to Byakuya that in three days, she will make Ichigo stronger than him, and until then, the fight between the two will be on hold. As she uses Shunpo to leave, she tells Byakuya that he can follow her if he chooses, but the "Goddess of Flash" will not be caught so easily.

When Yoruichi finally gets Ichigo back to the secret underground area, she is noticeably out of breath. She figures it was because she was out of practice after refraining from fighting for 100 years. She looks down at Ichigo and tells him to wake up, relaying that he can get stronger and that when he wakes up she will tell him about Zangetsu's real power and some secrets.

After Ichigo wakes up, Yoruichi tells him that she has no time to wait for his wounds to heal completely, so it will hurt quite a bit but before she can go, Ichigo grabs her by her shirt and asks her why she only brought him back, expressing his rage stating that the only one back there that could survive was him and because of her saving only him the others could have been killed Yoruichi calmly tells him not to think so highly of himself as he had no chance of surviving that fight. She goes on to say that no one there would have survived a fight with Byakuya. Yoruichi knocks Ichigo down and tells him to stop fighting or else he will open up his wounds again. She then explains that to still be able to outrun Byakuya one person is all that should carry. This prompted Ichigo to ask why she didn't take Rukia instead. Yoruichi then tells him that it is true that no one back there could have defeated Byakuya, but in three days it may become possible for him. She notes that this is the reason she brought him back. Yoruichi tells Ichigo that aside from Byakuya, Ukitake was also there. Even though Ganju is an intruder and Hanatarō is a traitor, he will not let them die because they were trying to save Rukia. She further assures him not to worry because in three days time she will make him strong enough to defeat Byakuya and save everyone. Ichigo gets ready to begin combat training and takes out his Zanpakutō. Before they begin, Yoruichi asks Ichigo if he has ever noticed that Zangetsu is always in its released form. Ichigo is somewhat surprised but asks if that makes it like Kenpachi's Zanpakutō. He notes that he now understands why it's so much bigger than other Zanpakutō, as it won't change shape when he calls its name. Yoruichi realizes that he hadn't previously known that and goes on to say that he probably didn't know that there is another level of release for Zangetsu. Ichigo is confused so Yoruichi explains that its not just Zangetsu but all Zanpakutō have two levels of release. The first one is called Shikai (initial release) and the second is Bankai (final release) and one must be able to do both in order to become a captain. She goes on to say that every captain can do the Bankai release with one exception, Kenpachi Zaraki. Yoruichi explains that in the long history of Soul Society, Zaraki is the only who has become a Captain without even knowing the name of his Zanpakutō. She states that his raw strength is not to be taken lightly even by the Gotei 13, noting that Ichigo should know this seeing as he has fought him. Yoruichi explains to Ichigo that the power and forms of the Shikai and Bankai are dependent on the Zanpakutō They also vary according to the wielders strength and training, but in general one's power can grow 5 to 10 times greater. Ichigo is in disbelief about the level of power that can be attained. Yoruichi notices his surprise and asks him if he is scared, noting that it is because from being able to do the Shikai to Bankai, even the most gifted Shinigami need at least 10 years to train. Ichigo tells her that he doesn't have that much time, though Yoruichi interrupts him telling him she is fully aware of that, and she will use a different, but more dangerous method to make him learn how to do Bankai in 3 days.

Yoruichi brings out a large white doll, to which Ichigo questions what it is for. Yoruichi remarks that it is a Tenshintai, a rare artifact of the Onmitsukidō, which can forcibly materialize the spirit of a Zanpakutō. Ichigo exclaims that he doesn't really get it, as he can't see what it has to do with achieving Bankai. Yoruichi tells him that it's obvious, and goes on to explain the requirements for attaining Shikai and what is required in order to achieve Bankai. She makes note that materialization means the opposite of getting dragged into the Zanpakutō's world in one's conversations with it. Instead one needs to summon the Zanpakutō's spirit into our world. Doing so usually takes 10 years or more to achieve. Yoruichi explains that even though it ended in a draw, Ichigo managed to fight Zaraki till the end. It is this that makes her believe that Ichigo is subconsciously at the materialization level. Yoruichi notes Ichigo's expression and sees that he has obviously experienced this before. She explains to Ichigo how to work the artifact, as all he has to simply do is stab his Zanpakutō onto it and it will forcefully materialize the spirit, while Yoruichi will use her power to keep it materialized. Before they start she warns him that the time limit is three days and he only has one chance at this, before the time is up he must beat Zangetsu into submission. Ichigo stabs the artifact and Zangetsu materializes into the real world. Yoruichi asks Zangetsu if he's heard everything, to which he responds that he has, and she tells him that he will choose the method of combat and asks if they can begin immediately. Zangetsu tells her that he will, and prepares the battle. As Yoruichi watches the battle unfold between Ichigo and Zangetsu, she thinks about how fast Ichigo has improved in a fight, noting his amazingly fast growth.

As the first day of training ends, Zangetsu dematerializes and Ichigo relaxes in a hot spring. He becomes agitated when Yoruichi tells him she is going to join him, they get into an argument until she enters in her cat form to which Ichigo calms down. While resting, Ichigo tells Yoruichi that this underground area looks similar to the one under Urahara's shop. Yoruichi tells him that it should, as the one under the shop was most likely modeled after the area they are in now. She states that the underground area was built when she and Urahara were young, as he dug the place in secret for their combat training. When Ichigo asks how he dug such a huge hole in secret, Yoruichi explains that ever since they were young Urahara always took things over the top when they were secret. She recalls that that was a long time ago, they used to play down in the underground area all the time. They got older and she joined the Onmitsukidō and Urahara joined the Gotei 13 and would train in the secret underground area in order to help each other get stronger. But before she could finish Ichigo interrupted, finally realizing that Urahara was a former member of the Gotei 13, making him a Shinigami. Ichigo comments on how he always thought it was strange that Urahara knew so much about Soul Society and had a Zanpakutō, and what topped it all off is when he mentioned his name everyone's face changed. Ichigo then asks who Urahara really is. Yoruichi states that keeping other's in the dark is how Urahara is but relents to tell Ichigo the truth; Urahara was the former Captain of the 12th Division of the Gotei 13 and the founder and 1st President of the Shinigami Research and Development Institute.

As Ichigo is warming up for another day of training, Yoruichi ponders the possibility of extending his training, noting that Ichigo is growing far in excess of what a normal Shinigami is capable of, though it is only his combat techniques that are improving while his spiritual energy remains the same. She makes a decision that if his spiritual energy has not increased within the next day she will just have to go with what she has helped him developed to, as there is no room for an extension and it would be too dangerous at this point.

Yoruichi is present when the secret underground training area is breached by Renji, who proceeds to tell her and Ichigo that they have little time to waste as Rukia's execution has been moved again and will take place at noon tomorrow. Yoruichi is surprised at this new information, realizing that there is no way Ichigo will attain Bankai in that small amount of time. Ichigo refuses to give up and tells Yoruichi that this training method was her idea and that she shouldn't give up before everyone else. Yoruichi is still unsure and questions if Ichigo can attain Bankai by tomorrow. Ichigo tells her he has the resolve and that he will gain it before noon tomorrow. Renji eventually finishes training and asks Yoruichi if Ichigo is going to make it, to which she says that she is not worried as she has become assured that it is because of instinct, that he will learn to attain it.

To help Ichigo in his rescue of Rukia, she lends him the Tentōken, a cape that is capable of allowing its user to fly by injecting some spirit power into it. When Suì-Fēng, Captain of the 2nd Division attacks Kiyone Kotetsu, 3rd seat of the 13th Division, Yoruichi saves her by using Shunpo and grabbing Suì-Fēng away and taking her with her off the edge of the cliff. At first, Suì-Fēng wonders who this is, as Yoruichi is wearing a cloth to cover up her face but Suì-Fēng recognizes her voice as Yoruichi pulls down the cloth to reveal her face, stating that it has been a while since they have seen each other. Yoruichi engages Suì-Fēng in hand-to-hand combat before the two put some distance between themselves up in the trees of the forest they landed in. Suì-Fēng comments that even though they have not seen each other in a long time, Yoruichi has not gotten any stronger. Yoruichi states that on the contrary she thinks that Suì-Fēng has in fact gotten weaker. Suì-Fēng notes that the Tentōken that Ichigo was wearing had the emblem of the Shihōin family and asks if Yoruichi gave it to him. Yoruichi plainly admits it as she states that flight was necessary to rescue Rukia at the time. Suì-Fēng states that the Tenshiheisonban, the Shihōin family, has also fallen, as if Yoruichi's actions of helping the drifters is found out, her family name will surely be removed from the list of the 4 great families, similar to how the Shiba family fell from nobility. She notes that the fall of a noble family is not a pretty sight at all. Yoruichi asks why Suì-Fēng is talking so much, taunting her by saying she is either excited to see her old mentor or she is blowing of steam from her position as Commander-in-Chief of the Onmitsukidō. She asks Suì-Fēng if it was stressful being her successor. Suì-Fēng tells her not to get cocky and think she is still better after all these years. Suì-Fēng states that both the Onmitsukidō and the Executive Militia are now under her control, as Yoruichi's era has ended a long time ago and she proceeds to take out her Zanpakutō and stabs it into the tree. Without notice, Yoruichi is surrounded by a cadre of Executive Militia members. Suì-Fēng asks if she remembers what happens when the Corps-Commander of the Executive Militia draws her sword; the execution begins. Before anyone can react, Yoruichi uses her great skill in Shunpo and takes out every Executive Militia member in the area in within seconds, much to Suì-Fēng's surprise. Yoruichi tells her to stop looking down on people so much, as there is still one title that she did not give away. Suì-Fēng takes off her haori and tells then she will take the title of from her.

Yoruichi comments on the Suì-Fēng's attire, noting that she is wearing the battle suit of the Corps-Commander of the Executive Militia. Suì-Fēng attacks Yoruichi and they begin to fight once again. Suì-Fēng notes that they have reached a draw both gaining a hit on one another. Yoruichi comments on Suì-Fēng's outfit, as to her, it seems to prevent her from seeing her movements. Suì-Fēng asks her if she really thinks it is a trick and uses Shunpo to appear behind Yoruichi and holds her Zanpakutō up to her throat as she releases her Shikai. Yoruichi uses Shunpo to get away but Suì-Fēng catches up to her and lands an attack. They move apart once again and Suì-Fēng tells her to admit that she is stronger as it may not occur to her that she is holding back. She states that she has become stronger than Yoruichi, and with her death and will make her pay the price for staying away from battle for a hundred years.

Suì-Fēng asks Yoruichi if she remembers her Suzumebachi special ability, as a "Hōmonka" appears on her chest. Suì-Fēng explains the mechanics of her Zanpakutō's Shikai. Suì-Fēng appears behind Yoruichi and attempts a second strike, but Yoruichi uses Shunpo to escape, after getting a ways ahead Yoruichi turns around goes on the offensive. Suì-Fēng asks if she now understands that she is stronger than her, and that if she understands then she will end this battle quickly. Suì-Fēng the uses her new technique that combines Kidō and Hakuda together, exclaiming that she has never used it in battle as she has only recently invented it. She notes there isn't even a name for it. Yoruichi, however, tells her it has a name; Shunkō. Suì-Fēng asks her what she is talking about. Yoruichi explains asking her if she knows why the executive militia's leader's outfit has no cloth on the back or shoulders, because it is meaningless. Yoruichi then uses the same technique but at a more advanced level then Suì-Fēng's, explaining what the technique does in detail to her former protege. Yoruichi further states that she wasn't planning on using this against her but warns Suì-Fēng to be careful as she also can't control it perfectly yet as she sends a wave of condensed Reiatsu toward her. When the smoke clears the land between the torn and scorched, Yoruichi asks Suì-Fēng if she now understands why she never showed her this technique, as it is to dangerous. Suì-Fēng goes to attack her but Yoruichi nullifies it with Hankei, and tells her to stop as it is too soon for her to be using the technique. Suì-Fēng begins to attack Yoruichi again yelling at her that she is stronger and that she should have surpassed her, that Yoruichi should have weakened all these hundreds of years and that she should have grown stronger. She asks how it is possible that Yoruichi still so far above her after all this time. She then relays all of her pent up feelings at being disappointed, betrayed and abandoned by her former mentor, when she left all those years ago. All the while Suì-Fēng continues to attack as Yoruichi moves effortlessly out of the way. But then Yoruichi stops the attacks by initiating a Shunko powered punch but stopping short of actually hitting Suì-Fēng. Upset and unwilling to fight anymore Suì-Fēng breaks down and cries and ask Yoruichi why she did not take her with her. Suì-Fēng bows down to Yoruichi in defeat.

Yoruichi is with Suì-Fēng when Isane Kotetsu broadcasts the news of Captain Aizen's treason. They are amongst the first to arrive on the scene to stop Aizen. Yoruichi stops Aizen’s Zanpakutō from being released, while Suì-Fēng holds her Zanpakutō to his neck. She tells him not to move a muscle as Suì-Fēng tells him he will lose his head if he does. When Aizen notices Yoruichi he comments at her face being nostalgic. Yoruichi is noticeably surprised that three of the gate guardians have turned traitor as well but is happy to see Kūkaku show up with Jidanbō to combat them. Once his cohorts have been subdued Yoruichi tells him that it is the end. Aizen asks her what did she say, and she plainly asks him doesn't he sense it, he has been completely surrounded by the Gotei 13. The overall attempt to stop him, however, was then thwarted by the arrival of Gillians' who use their Negación to aid in Aizen's escape from Soul Society, with Yoruichi telling Suì-Fēng to jump away just in time. Yoruichi later returns to the living world with the others.

Bount arc (anime only)
Note: Events occurring in this arc are only in the anime and do not constitute canon material.

While in her feline form Yoruichi, alongside Suì-Fēng, investigate human disappearances in the living world. Noting that the culprit is moving fast and attacking at an alarming rate Suì-Fēng sends her findings to Captain Ukitake in Soul Society. Yoruichi and Suì-Fēng make there way to the train station in time to see a Bount attempting to feast on the soul of a train conductor. Yoruichi transforms back into her true form and proceeds to attack the Bount to stop her from feeding on the helpless man. The Bount gets away, and Suì-Fēng asks Yoruichi whether she knows the person to which Yoruichi confirms that she does but not in the current form that she is in. She tells Suì-Fēng to go back to Soul Society and give them her report of what's taking place.

She later actively begins to pursue the Bounts once they learn of the Bount's plan to invade Soul Society, and also saves Ichigo when he is unable to defeat Jin Kariya. Later after the defeat of Kariya and the other Bount, Yoruichi rescues the redeemed Bount Gō Koga and takes him to the home of Ran'Tao, the Bount's creator, where he was nursed back to health.

Arrancar arc
When the Arrancar Ulquiorra Cifer and Yammy Riyalgo begin to terrorize Karakura Town, Urahara and Yoruichi show up to save Ichigo from Yammy. After Urahara blocks his punch with his blood mist shield, Yoruichi easily dispatches Yammy, only for the enraged Arrancar to try to attack her from behind as she goes to help an injured Orihime. Yoruichi turns around and brutally attacks Yammy, literally pounding him into the ground. As Yoruichi goes back to helping Orihime, Yammy gets up enraged and attempts to hit her with a point blank Cero, but it makes no contact as Urahara counters it with a similar attack to nullify Yammy's. When Yammy becomes confused at the concept of this Urahara decides to show off and sends a blast of spiritual energy from his Zanpakutō toward Yammy, but it is deflected by Ulquiorra with his bare hand. Ulquiorra incapacitates Yammy for his rash actions and brutishness and proceeds to explain to him who it is that he is fighting. The two Arrancar then return to Hueco Mundo.

Later, while at Urahara's shop, Yoruichi is shown recuperating from an injured left arm and leg. When Urahara expresses concern about her state, Yoruichi admits that she was foolish to fight him without using Shunkō, though she didn't think the Arrancar's skin would have such dense spiritual pressure. She confirms that the Arrancar are tougher than either she or Urahara had anticipated.

She appears again to take Orihime Inoue into the training room under Urahara's shop, so that he may speak to her about the upcoming battle.

The New Captain Shūsuke Amagai arc (anime only)
Note: Events occurring in this arc are only in the anime and do not constitute canon material.

Yoruichi briefly comes to aid Ichigo in his fight against Hanza, freeing him from special ability of Saiga. She then tells the would be assassin that his cohorts have all been defeated. Upon realization of this Hanza makes his retreat.

Later while in Soul Society Yoruichi helps Suì-Fēng in understanding what truly was going on with the Kasumiōji family. She then shows Suì-Fēng a technique taught to her by Urahara, allowing Suì-Fēng the ability to break through a barrier placed around the Kasumiōji foundry by royal blood, supposedly making the shield impenetrable. Yoruichi later shows up to explain to the vengeful Shūsuke Amagai that he was misguided and the truth of the matter is documented in her families historical records.

Fake Karakura Town arc
When Urahara and Isshin Kurosaki immobilize Aizen, Yoruichi appears wearing armor on her arms and legs and attacks Aizen from above. She smashes into his back with such force that it destroys the surrounding area and then she lands a direct punch with even more force, causing damage to an entire block. Urahara then yells for Yoruichi to move away. Aizen quickly recovers and before Yoruichi can fully dodge his counterattack, he destroys the armor on Yoruichi's left leg. As Aizen emerges from the rubble with his new form severely cracked, he asks them if this all they have. Stating that they better hurry up and make the next move as he plans on crushing them all one by one into tiny fragments down to the very last remnant. When Urahara expresses his surprise at how the armor he created could be destroyed with one blow from Aizen, Yoruichi tells Urahara off for not building the armor properly. Urahara warns Yoruichi to keep away as they prepare to face the next attack, but she remarks that she will be fine as long Aizen does not attack her exposed leg. Aizen's next blow takes her completely by surprise. Managing to escape Aizen's assault at the cost of her right armguard, Yoruichi complains to Kisuke when he asks if she is alright. She tells him that she was able to block the attack because of the "half-finished" armour, but that she would have simply dodged it without the armour. After they stop arguing, Kisuke launches a Kidō blast at Aizen. Yoruichi takes advantage of this and attempts to attack Aizen, but he anticipates their ploy and blocks her attack. She then follows up with a Shunkō assault, knocking him to the ground. Aizen then blocks her next attack. Kisuke interrupts by immobilizing Aizen with Benihime. Along with Kisuke and Isshin, Yoruichi is defeated by Aizen, who then leaves for the real Karakura Town in Soul Society.

Zanpakutō Unknown Tales arc (anime only)
Note: Events occurring in this arc are only in the anime and do not constitute canon material.

Yoruichi is sent on a recon mission into Soul Society, to survey what has happened in the wake of the recent Zanpakutō rebellion. She returns to Urahara's Shop and confirms that everyone in the Seireitei is okay. She explains what she witnessed. How the Seireitei looked as if it had been through a war and the buildings were in ruin. She naturally assumed the worst and went to go look for the 4th Division to get a better understanding of the possible casualties. Yoruichi meets with Captain Retsu Unohana of the 4th Division and Captain Ukitake. They tell her the tale of the fight that has taken over Soul Society and the damage done. Before leaving Yoruichi assures them she will talk to Urahara and see if he knows anything of use to help the situation. Before she goes Unohana asks that if all else fails on her end that maybe she could enlist Ichigo's help in the matter, to which Yoruichi concurs. After she is finished telling her story Rukia asks if Yoruichi knows of the status of her brother, but Byakuya is nowhere to be found. The next day when Rukia turns up missing Ichigo and Yoruichi set out to Soul Society to search for her.

Later, Yoruichi helps carry an exhausted Suì-Fēng to the others after her former protege managed to defeat her Zanpakutō. Upon finding the others, Yoruichi reveals that she has discovered the location of Yamamoto. She brings them to a network of caves that the Zanpakutō have been using, from which Yamamoto's Reiatsu can be sensed. When the captains enter the cave to find the Captain-Commander, Yoruichi takes Ichigo to another entrance. As they leap from one stalagmite to another in the flooded cave, Yoruichi tells Ichigo that she does not know what Byakuya's motives are, but that he likely has a plan. When she is attacked by Tobiume and Haineko, she quickly over-powers them and tells Ichigo to go on ahead. Yoruichi effortlessly fights the two Zanpakutō spirits using a combination of Hakuda and Shunpo, before realizing that they aren't so much as trying to defeat her but rather keep her from advancing forward. To test her theory she allows them to attack her directly as she sneaks off past them but they quickly realize her ploy and refuse to allow her to escape. Yoruichi counters their attack by using Hadō #31. Shakkahō, though Yoruichi ends up trapped when Tobiume's fireball caves in her escape route. She then confronts the Tobiume and Haineko about they're plan to keep her there fighting them and decides that she can no longer allow them to hold her back, Yoruichi then uses Hadō #58. Tenran to destroy the obstruction of rocks from the path and binds both Zanpakutō spirits to the wall with Bakudō #30. Shitotsu Sansen.

Yoruichi makes it just in time to see Ichigo has already used his Getsuga Tenshō at its most powerful (enhanced via his Bankai and Hollow Mask), causing an large explosion. When the dust settles she makes her way to Ichigo alongside Ukitake and Shunsui, who are surprised to find the barrier Yamamoto was in now shattered. They all realize that they were all wrong in the assessment that Muramasa had placed the barrier around the captain-commander, realizing too late that Yamamoto himself put the barrier up so that Muramasa couldn't take control of his Zanpakutō spirit as he did with the others. Muramasa confirms their realization stating that by placing himself in a barrier and going unconscious he had no way into the captain-commanders mind, he in fact brought out the Zanpakutō spirits of the other Shinigami and staged the Zanpakutō Rebellion all to lead to his final goal. Yoruichi and the others are in surprised at the turn of events and witness the enraged Katen Kyōkotsu and Sōgyo no Kotowari move to attack Muramasa for his betrayal and manipulating them. They are all surprised when large wall of flames incinerate the two pairs and recognize that Muramasa now has control of Ryūjin Jakka. Trapped inside Ryūjin Jakka's flames, Yoruichi blasts a hole through a collapsed exit. However, she is attacked by Tobiume, who causes the newly opened path to collapse again, separating Yoruichi from the others. She then finds Tobiume and Haineko and prepares to fight them again.

Equipment
Two of Yoruichi's unique items are accessories which grant the user the power of flight.


 * A long beige bone wand-like artifact with a small white bird shaped skull with four protrusions similar to fingers bones extending from the back of the skull. By channeling Reiryoku in the wand, it produces a tentacle that acts a harness and a single bat-like wing manifests from the four bone protrusions, which acts as a one handed hang glider. No skill or previous experience is required to use it.


 * it is a brown mantle with a large draw string closure at the collar and a large brooch displaying the Shihōin family crest. Like the wand, the Tentōken seems to require no skill or previous experience to use. It also seems to be superior to the wand, since it allows one to hover in mid-air and does not immobilize one of the user's hands.


 * are small knives that Yoruichi hides in her boots. She can launch them at a target with a swing of her leg.


 * Anti-Hierro Armor: a set of metal gloves and boots invented by Kisuke Urahara, specifically designed to counter an Arrancar's Hierro during hand-to-hand combat. They are exceptionally durable, capable of protecting the wearer's limbs even during the moment of their destruction.

Powers & Abilities
Feline Transformation: Yoruichi possess a unique ability which allows her to shape-shift into a black cat at will. How she alone out of all Shinigami is capable of this is yet unknown. Though she has apparently possessed the ability for well over 100 years, and its apparently known to others she knew from that time. She apparently has no set time limit on the transformation as she had been in the assumed form for over 100 years. In cat form, Yoruichi can still channel her spiritual energy and move at incredible speeds, though she is physically limited by the form. Her transformation also allows her a complete disguise, as her voice in this form is deep enough for most to assume she is a male. This, of course, leads to awkward situations when she reveals her true form.

Hakuda Master: Yoruichi as former Commander-in-Chief of the Onmitsukidō is one of the most accomplished hand-to hand combatants in Soul Society. Her mastery of the art form is so great that she uses it exclusively as her form of combat of choice forgoing the use of a Zanpakutō altogether. She has been shown to take down nearly 50 Onmitsukidō members with only Hakuda. She has been shown taking on the likes of Espada-level Arrancar as when she brutally defeated Yammy and is even regarded by the 4th Espada Ulquiorra Cifer as highly dangerous.

Expert Swordsmanship Specialist: While preferring to fight her opponents barehanded, during flashbacks of her days as a captain, Yoruichi showed herself to be a highly capable swords-woman from her ability to take down a huge Hollow with a single strike of her sealed Zanpakutō.

Shunpo Master: Considered to be the most proficient Hohō master ever in all of the Soul Society, Yoruichi is highly skilled in the use of Shunpo, a high speed movement ability. Though this is by no means a unique skill, as most seated officers are capable of performing it to various degrees, Yoruichi holds the title, because she has mastered this ability to such an extent that she can appear to be in several places at once and wipe out an entire Onmitsukidō squadron in seconds. She can easily close tremendous gaps of distance in the blink of an eye while remaining undetected, as shown from her ability to surprise Byakuya, who is one of the most proficient in the art as well. She has mastered all of the Onmitsukidō's speed-oriented techniques and even created some of her own, such as Utsusemi (空蝉; cicada, referencing their molting). The full extent of her abilities remain unclear, but she was able to outrun Byakuya while carrying an unconscious Ichigo over her shoulder, where she was able to perform around 300 steps before feeling tired from 100 years of being out practice. She is so fast that Suì-Fēng could barely keep up while Yoruichi was still holding back. It is revealed that she can still perform Shunpo even while in her cat form. Unfortunately for her, she is not as fast as she is in her true form.


 * Way of Onmitsu, 3rd of the Shihou. It allows for a movement at great speed, leaving at least one tangible after-image behind. Byakuya Kuchiki states that she taught it to him.

Enhanced Strength: Despite her slender appearance, Yoruichi is quite strong in her Shinigami form; she could still easily use flash steps while carrying around an unconscious Ichigo to outrun a fellow flash step master. She can also easily catch a direct punch from the 10th Espada, and simultaneously throw him several feet away. She was able to easily injure him despite his thick Hierro with various unarmed moves, but it was later revealed that she was injured by his Hierro. Though she admitted that she wasn't expecting his skin to be that hard, she states that she could have avoided taking any damage if she had Shunko activated. Yoruichi has shown the strength of a concentrated blow from her is highly destructive, capable of destroying an entire city block.

Enhanced Endurance: Despite her own admission of being out of shape, Yoruichi has shown to be a very resilient warrior. Both when out of breath from prolonged running against Byakuya and sustaining fractures from Yammy's Hierro, Yoruichi was still able to fight effectively while showing no signs of weakening.

Master Assassin: As the former Commander-in-Chief of the Onmitsukidō, Yoruichi is one of the foremost masters of the art of assassination. She has repeatedly shown impressive skill in staying hidden and unseen. When necessary, she can effectively exploit having a advantage against an opponent or hiding her presence. Even one as intuitive as Aizen was completely taken by surprise and just as easily subdued.

Master Strategist: As the former head of her clan and ex-commander of the Onmitsukidō, Yoruichi has shown herself to be a capable leader. Repeatedly, Yoruichi has shown to be insightful and crafty, quickly capable of understanding any situation that presents itself and adjust to it effectively. Upon learning that Ichigo would go to save Rukia no matter what, Yoruichi began making preparations of her own by training Orihime and Chad.

Kidō Expert: As former captain of the 2nd Division and the Commander-in-Chief of the Onmitsukidō, Yoruichi is well-versed in a mastery of Kidō. Though she commonly employs Shunpo and hand-to-hand fighting techniques, she is masterful in using Kidō to further her capacity in combat - being so experienced she is able to mix it with other fighting techniques. She has been shown using mid-level binding and destruction spells with no incantation with expert skill.


 * An advanced technique that combines hand-to-hand combat with Kidō. She fights by surrounding her back and arms with pressurized Kidō. The keisen uniform has no back or sleeves since they will rip apart when it is activated. The technique can allow her to instantly neutralize an opponent's movement, apart from enhancing their arms and legs for battle. The Kidō itself can also be controlled and fired at opponents from her body, and can be used to create massive explosions. Yoruichi's version of the technique was developed and studied by her a century ago. Therefore, the technique is complete. Unlike Suì-Fēng's version, the compressed Kidō is visible.


 * This technique is an ability Yoruichi uses during Shunkō, which nullifies an opponent's Kidō by hitting it with a Kidō of perfectly opposite speed and energy. The ability can even neutralize an opponent's movements.

Immense Spiritual Power: As a former captain and head of a noble clan, Yoruichi boasts a great amount of spiritual energy. Her spiritual energy is great enough to act as a shield from fairly powerful attacks, as seen from blocking Jin Kariya's lightning blast with a single hand. While using Shunkō, her concentrated spiritual power becomes far greater than normal.

Zanpakutō
As a former captain of the Gotei 13, it is known that Yoruichi possesses a Zanpakutō and has achieved Bankai, but she relies nearly exclusively on Hohō, Shunpō, and Shunkō. Although she doesn't carry it at all in the current time, she is shown wearing it in the past. It resembles a kodachi or wakizashi which she kept sheathed horizontally behind her on her lower back, similar to how Suì-Fēng carries hers in the present day.


 * Shikai: Not Yet Revealed


 * Bankai: Not Yet Revealed

Quotes

 * (To Orihime Inoue and Yasutora Sado) "Just like a person holding a sword trying to protect something. That maybe one's life, or place in society, or reputation, things that one loves, things that one believes; it matters not if it's good or bad, the will to 'protect it' does not change."


 * (To Orihime and Sado) "Heart and Soul are connected, what is important is where is the heart."
