Retsu Unohana

"Genuine elegance." - Tite Kubo

is the Captain of the Fourth Division in the Gotei 13. She is one of the oldest and most experienced captains, and is Soul Society's best healer.

Appearance
Unohana has the appearance of a very youthful woman with blue eyes and black hair. She wears the standard Shinigami captain uniform apart from using an obi instead of the normal sash. Her hair is long and is always worn as a large braid in front. Over 100 years ago, she didn't have the large braid.

Unlike most Shinigami who carries their Zanpakutō in their sash, Unohana has a large string attached to the sheath of her Zanpakutō and carries it over her shoulder, or has her lieutenant Isane Kotetsu carry it for her, whenever they are together on the battlefield.

Personality
Unohana has a gentle and warm personality that augments her appearance. Unohana is a soft-spoken, polite, and caring woman who uses honorifics when addressing everyone, including her subordinates and the enemy. She rarely shows any signs of panic or distress, and has a great sense of duty, shown in the times that she orders Hanatarō Yamada’s imprisonment and Isane Kotetsu’s chasing of Renji Abarai when he runs away with Rukia Kuchiki. With her grace and kind manners, she lets others know quietly that while she may be soft, she is not to be taken lightly. Despite her gentle nature, several members of the Eleventh Division and even her fellow Captains fear her.

Also according to the former captains of the 5th and 7th Division, respectively, she can be very frightening as the look on their faces implied they would never want to get on her bad side (they noted that being destroyed by Shigekuni Yamamoto-Genryūsai's Bankai would be a preferable fate). No one has ever disputed this fact, for she is an indispensable part of Soul Society and the Gotei 13 Squads.

Unohana likes strong flavored food, preferring it to bland tasting dishes. In her free time, she climbs mountains throughout Rukongai, during these excursions, she collects medicinal herbs. Once a month, she holds an ikebana class for the members of her division. Unohana is also the President of the Ikebana Club (Flower Arranging Society.)

History
Although not much is revealed about her past, it is said that she has been a captain for at least 200 years; along with fellow captains Genryūsai Shigekuni Yamamoto, Jūshirō Ukitake and Shunsui Kyōraku. It is stated that the four of them have been Captains of the Gotei 13 for at least 200 years as of 110 years ago before the current time. This makes her one of the oldest captains among the Gotei 13, despite her rather youthful appearance. Ukitake also refers to her as "Senpai" denoting her seniority to both him and Shunsui.

Approximately 110 years ago she is seen waiting for the promotion ceremony to begin at the 1st Division Headquarters along with the rest of the assembled captains. She witnesses the arrival of the newly appointed Captain of the 12th Division, Kisuke Urahara. Her lieutenant at this time was Seinosuke Yamada.

9 years later Unohana is present at a emergency meeting called by Captain-Commander Yamamoto. When he decides to create a investigation team to locate the missing 9th Division squad members. When he gives out orders, Yamamoto orders Unohana to prepare the relief stations for casualties, but Unohana interrupts and asks if it wouldn't be better for her to tend to the wounded there. Yamamoto plainly tells her that he can't send healers out without knowing what the situation is like.

Soul Society arc
Retsu Unohana first appears during the captain's emergency meeting called by General Yamamoto. However she says nothing at this time, and remains silent throughout the constant bickering between her fellow officers. She is next seen after Sōsuke Aizen's apparent death, in which she confirms to Sajin Komamura and Kaname Tōsen that he is truly dead. She later appears shortly afterwards when Hanatarō Yamada is "caught" by Jūshirō Ukitake and brought before Unohana for judgement. Despite the reasons put forth by Ukitake, she determines that Hanatarō must be imprisoned on account of the fact that he is a seated officer in her division and may have incidentally aided in the harm that the Ryoka had supposedly done within the Seireitei.

As head of the medical relief division, Retsu Unohana’s healing prowess is legendary. This is first shown when she manages to heal Renji Abarai after his defeat at the hands of Byakuya Kuchiki. She manages to save Renji from certain death, while also delaying her arrival at the Sōkyoku Stand for Rukia Kuchiki’s execution. While attending the execution, Isane Kotetsu expresses open regret that Yamamoto lied to Rukia regarding the release of the Ryoka, but Unohana explain to her lieutenant that despite the harshness of such a lie, it also allows Rukia to die peacefully with the idea that her friends' lives would be spared.

After Ichigo Kurosaki arrives on the scene and destroys the Sōkyoku stand, Soifon orders all lieutenants to follow after the fleeing Renji and Rukia. As Isane looks concerned at Unohana about the order, she calmly tells her to go, only to see her get beaten. Amidst the chaotic scenes, Ichigo starts his battle with Byakuya Kuchiki, the respective captains then head off to their own battles. Unohana releases Minazuki, even though the actual process is not shown, and saves all those hurt during the initial battle. She keeps Isane with her on top of Minazuki while her Zanpakutō heals the rest of her patients inside of its stomach. Arriving at the Relief Station, Unohana asks Minazuki to release everyone, and seals it back while calling for her subordinates to tend to the injured personnel for the time being. She then asks Isane to follow her to the Central 46 Chambers.

They arrive at the scene in time to see Aizen defeat Tōshirō Hitsugaya. Captain Unohana announces her presence to the traitors while citing her own suspicions surrounding Aizen's staged death. She also goes on to claim that the residence area in Central 46 Compound was the only place he could hide and mentions the use of an elaborate corpse doll on his part. Aizen then points out the mistakes in her analysis, while also commending her for seeing through his deception. The first was that he was not here to hide, and the second was immediately shown as he releases his Zanpakutō in front of Unohana and explains Kyōka Suigetsu's Complete Hypnosis. He then proceeds to tell Unohana about the third member of his group, Kaname Tōsen. He and Gin Ichimaru then teleport to Sōkyoku Hill, leaving them behind. Unohana immediately requests Isane to find out his exact location, while informing everyone of Aizen’s betrayal, including the Ryoka. She then takes steps to save Hitsugaya and Momo Hinamori, both of whom were fatally injured by Aizen before her arrival.

After ensuring that both would escape death for the moment, she leaves them in the care of Isane and travels via Minazuki to the Sōkyoku stand, where she tells Yasochika Iemura, the 3rd Seat of her division, that the Ryoka do not require help. She then settles down beside Byakuya Kuchiki and gently scolds him, saying that he has pushed himself too hard. She then calls Rukia over upon Byakuya’s request, during which he reveals his reason for allowing her execution.

A week after Aizen's insurgency, Unohana stops two Squad 11 members from creating a ruckus at the 4th Division’s Relief Station, and unsuccessfully tries to convince Hitsugaya to speak to an unconscious Momo, who is still recovering from her injuries.

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

Unohana first appears during the Bount Invasion. Commander Yamamoto calls a captain's meeting to discuss the invasion, wherein he tells the captains to kill the Bounts on sight.

When the Bounts infiltrate Seireitei, Mabashi uses Ritz to possess Shinigamis in order to create infighting. Many who were possessed were brought to the 4th division's infirmary to be healed. However, as she doesn't know how to remove the implanted doll, she orders all those possessed to be restrained and the puppetmaster captured. When Mabashi is killed by Soifon, all of the possessed Shinigami return to normal. Unohana expresses relief that someone defeated the puppetmaster.

Hueco Mundo arc
Unohana and Isane appeared alongside captains Kenpachi Zaraki, Mayuri Kurotsuchi, and Byakuya Kuchiki in Las Noches after the titanic battle between Ichigo and Grimmjow Jaegerjaquez. Her initial appearance effectively stops the approaching Exequias from doing further harm to Yasutora Sado, in which the leader of the group calmly orders a retreat. She then stops Isane from pursuing them, claiming that they are only there to heal the injured, not start more fights.

She proceeds to heal Chad and Gantenbainne Mosqueda, and orders Isane to go the location of Byakuya Kuchiki as she feels something is wrong with Hanatarō, who was originally sent with Byakuya.

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

Unohana is summoned together with all of the captains and lieutenants to Sōkyoku Hill as Muramasa and the other manifested Zanpakutō spirits appear before their former masters, declaring their rebellion. She orders Isane to treat Chōjirō Sasakibe after he is injured by the Zanpakutō spirits. After that night, Unohana leads her division in healing those who were wounded in the battle the night before, including Komamura.

She and her lieutenant are later visited by Nemu with a request by Mayuri Kurotsuchi that Unohana come to the 12th Division barracks to determine the cause of the Zanpakutō's rebellion. Afterwards, she, Jūshirō Ukitake and Shunsui Kyōraku use the 4th Division to plan their strategies. When both Ichigo and Renji appear before the three captains announcing that they have both subdued their Zanpakutōs, they realize that the only way to restore control over them is to defeat them in battle.

After the Zanpakutō spirits attacked the 6th Division headquarters, Unohana appeared with the 4th division to heal all injured parties. Though she gets into a small rivalry with captain Mayuri Kurotsuchi over the fact that she analyzed and developed a cure to his Bankai's poison. She is there to greet Soifon and Yoruichi when the latter tells all in attendance that she has discovered the whereabouts of captain-commander Yamamoto.

Fake Karakura Town arc
Unohana appears alongside Mayuri Kurotsuchi after the latter announces that he can get Ichigo Kurosaki back to Karakura Town through a Garganta. She offers to accompany Ichigo back to Karakura Town, claiming to have faith in Mayuri's abilities, but not without adding a remark of how if he fails, Urahara will be disappointed, obviously irritating him. Before leaving with Ichigo, she orders Isane to remain behind and assist their remaining forces in Las Noches. When Mayuri and Nemu open up the Garganta, Ichigo and Unohana jump in and head towards Karakura Town. As they are travelling, she asks Ichigo about his fight with Aizen, when learning that Aizen defeated him without using Shikai, Unohana is somewhat relieved. She then informs him that he is the only one who can stand up to Sōsuke Aizen because he has not seen his Shikai. She tells Ichigo that his advantage is that not only does he have captain-class reiatsu, but also that he hasn't seen Aizen's Shikai. She finally warns him not to witness Aizen's Shikai, stating that once he does, the war would be over. Ichigo thanks her and tells her that he will defeat Aizen.

As they make their way back to the living world, Unohana notices that Ichigo is making a path that is weak and brittle, she ask that she be allowed to take the lead, but Ichigo protests, saying its unnecessary until she asks again even more politely, scaring Ichigo into submitting to her will. Once Unohana is in front Ichigo, she comments on how she can make such a clean & sturdy path with captain-class reiatsu, making note of the difference between them. Unohana asks him what he is referring to as his reiatsu isn't so different from hers, as his wounds are healed so it maybe that his reiatsu is too rough and thus unsuited for the particular task. Ichigo objects stating that if his reiatsu was at full strength, he would be able to do better. Unohana doesn't believe his reasoning until Ichigo explains that the condition his Bankai shihakusho’s gives a clear example of how much Reiryoku he has left, Orihime had already healed him but told him that it would take longer to replenish his Reiryoku and since he went to help Rukia and the others, his reiatsu never did get fully replenished. He then points to his sleeve that he has left and says this is how much reiatsu he currently has at the moment. Unohana then thinks to herself that it is impossible, as there is not even half of his shihakusho left causing her to wonder if his reiatsu is only at half. Unohana then realizes that she must have been under the illusion that Ichigo's reiatsu must be at full strength because it was comparable to a captain's. She then asks Ichigo to run in front while she restores his reiatsu to full strength as they travel. Ichigo questions if she is capable of doing that while they are running to which Unohana answers by explaining how healing Kidō works and that restoring the Reiatsu once a body has physically healed is an easy task. Unohana then acknowledges to herself that if Ichigo's reiatsu is only at half strength then he may just be the trump card they need.

Powers & Abilities
Master Healer: Unohana is by far the most knowledgeable on health related matters in all of Soul Society. She is known to be highly proficient in conventional healing techniques as well as herbal healing. Her knowledge of anatomy is high enough that upon examination of Aizen's "dead body", she concluded it was not Aizen or even real. She also seems to be able to heal more than just Shinigami, evident when she heals Yasutora Sado, a human, and Gantenbainne Mosqueda, an Arrancar.

Kidō Master: As the head of the Fourth Division, Unohana is known for her skills in the healing branch of Kidō.

Immense Spiritual Power: As one of the oldest Captains in the Gotei 13, it is safe to assume that Unohana has tremendous spiritual power.

Master Swordsmanship Specialist: Although she has never been seen in battle, it is known that her personal speciality is sword fighting, including her particular mastery in the kendō style of fighting.

Flash Steps Expert: Unohana is proficient enough in this skill to be of the average level of speed possessed by a Captain.

Keen Intellect: Along with her general skill of healing, she is able to detect the smallest details. This helps her in her mastery of healing. She can detect anomalies and problems lesser healers wouldn't. She can tell by a simple look what type of medical attention if any is needed. She also a powerful analyst with great attention to detail, able to quickly determine how to counteract any ailments in a person. Her powers of perception were also able to deduce that Aizen's elaborate illusion of a corpse doll wasn't real, but even more so that Aizen was perpetuating a much larger scheme.

Zanpakutō
Minazuki redirects here. For the manifested spirit that appears in the Zanpakutō Unknown Tales arc see Minazuki (spirit).


 * In sealed form, Minazuki is slightly longer than an ordinary katana, and resembles a nodachi The guard has an oval shape and the handle is red. Instead of tying it to her obi, Unohana carries her Zanpakutō over her shoulder by a rope strap or lets Isane carry it for her.


 * Shikai: Its release command is unknown. When released in Shikai form, Minazuki will start to morph, turning into a green like gas substance before taking a solid shape of a giant, green, one eyed Manta Ray like creature with the capability to fly. Minazuki can act as transportation and will change back into the green gas substance before returning to it's sword form when it's duty has been fulfilled.


 * Shikai Special Ability: It is large enough to transport many people on its back (at least a dozen, based on its size when compared to those riding it). It seems to act on verbal orders and when landing it has the ability to somehow create a pair of bird like legs. Minazuki's main aspect is its ability to heal. When the wounded are placed within Minazuki's mouth, they are swallowed and stored inside it's stomach. Minazuki's stomach acids are strong healing medicines and ointments which gradually soak over the wounded, curing their injuries. Currently it has shown to be able to carry at least five people within it's stomach. When Unohana gives the word, Minazuki will regurgitate the people back out of its mouth.


 * Bankai: Not Yet Revealed

Appearances in Other Media
Retsu Unohana does not appear as a playable character in many of the Bleach video games, but is usually only seen and having minor roles.

Bleach: The 3rd Phantom, would be the first video game to feature Retsu Unohana as a playable character. However, she is a non-combatant character and uses various healing methods while in play. She is also seen in the movies Bleach: Memories of Nobody, Bleach: The DiamondDust Rebellion and Bleach: Fade To Black.
