Yasutora Sado

, also known as, is a Human teenager who lives in Karakura Town. He is a student at Karakura High School, where he is in the same class as Ichigo Kurosaki.

Appearance
Sado is a teenager of Mexican descent with wavy brown hair that generally hangs over his brown eyes. He is a muscular and extremely tall man and appears to be much older than he actually is. Sado has a tattoo on his left shoulder which reads Amore e Morte ("love and death" in Italian) and consists of a heart with a snake and angel wings around it. He typically wears either his school uniform or flashy short sleeved shirts with open collars. He also wears a dark, long-sleeved shirt with a rose emblazoned on the left sleeve.

Personality
Sado is a quiet person and is sometimes the subject of jokes or bullies because he never fights back. Nonetheless, he is treated equally within his group of friends in Karakura. Sado also has a soft spot for cute things, like small animals and Kon's plushie form. Sado has also shown to be very intelligent; he ranked 11th out of 322 students in Karakura High School. Sado has a very loyal personality. He is quite loyal to his friends, especially Ichigo, who is one of his closest friends, even going as far as to try and defeat a Gotei 13 captain to go help him. He is also shown to be fearless and told so by numerous enemies such as the first Hollow he fights. He displays little emotion except when something he cares about is in danger.

Sado's favorite food is tomatoes. He also likes music, but rarely watches TV. The only programs he likes are Carnivore Kingdom, which starts at 8 a.m. on Sundays. He likes it so much that he bought the DVDs for it. As Kon is a cheap knock-off plushie of the main character of Carnivore Kingdom, Sado finds Kon especially cute. The other show he likes is Don Kanonji's Ghost Bust. Sado also has a bass guitar.

History
Sado was born in Okinawa, Japan, but was taken to Mexico by his parents at a young age. After their deaths, Sado was adopted at the age of eight by Oscar Joaquín de la Rosa, a man believed to be his grandfather since Sado calls him Abuelo ("Grandfather" in Spanish).

During his early years, Sado was extremely violent; exploiting his advantage in size, he intimidated and hit any other children who annoyed him. Oscar Joaquín tried to teach Sado to be gentle, but was initially unsuccessful. One day, the fathers of the children Sado fought, seeking to punish him, attacked Sado. Oscar Joaquín stepped in between them, taking Sado's punishment without retaliation. Sado was inspired by this example to become a decent person. To commemorate this event, Oscar Joaquín gave Sado a old Mexican coin; years later, when Oscar Joaquín had died, Sado made a vow that he would never fight unless it was to protect others, as instructed — even if his own life was in danger. The coin would come to symbolize this vow, which Sado now claims to hold more value than his own life.

Some time after De la Rosa died Chad moved back to Japan and entered Mashiba Junior High School at Karakura Town. In the 8th grade he helped Ichigo when the latter was attacked by thugs. Chad was later attacked by two of Yokochini's gang members and, keeping with his vow, did not strike back or defend himself. Ichigo intervened and saved him and later learned from Chad a little about his past, the meaning of the coin and the vow he made. However, as the gang members fled they left a cell phone with an ongoing call to Yokochini, allowing him to spy on Chad and learn what might get a rise out of him. Yokochini later had Chad abducted and threatened him with the destruction of the coin. Ichigo stuck his neck out again, this time to protect not only Chad, but also the coin he held so dear. When the gang was defeated, Chad and Ichigo made a pact to fight for each other and protect one another.

Because they were constantly involved with fights and brawls with thugs and delinquents, both Ichigo and Chad gained the reputation of hardened thugs themselves. Their reputation far exceeded that of violent youths as they were made up to be juvenile gangsters of sorts. On their first day of high school, Chad and Ichigo were forced into pushing back a gang of thugs led by Reiichi Ōshima, who was hell bent on proving his bravado by beating up such a menacing duo. When Mizuiro Kojima befriended them, Reiichi started bullying Keigo Asano, forcing the two to help him and beat up Reiichi.

Agent of the Shinigami arc
Sado first appears as a student in Ichigo's class. A few days after Ichigo becomes a Shinigami, Sado is offered a cursed cockatiel whose previous owners have all died horrible deaths. The bird is in fact the container for the spirit of a dead child, placed there by a Hollow who uses him as bait. Sado is forced to fight the Hollow despite not being able to see it, assisted by Rukia Kuchiki. Ichigo defeats the Hollow then performs a soul burial on Yūichi Shibata. Beforehand, Sado promises that he will carry Shibata around again if they meet in Soul Society.

Later on, when Uryū Ishida duels with Ichigo, Uryū unleashes a multitude of Hollows upon the town and Sado is pressed into battle with another Hollow in order to protect Karin Kurosaki. It is this event that awakens his spiritual powers, which manifest as armor on his right arm. He is later brought to Kisuke Urahara along with Orihime to have everything about the Shinigami world explained.

Soul Society arc
After Rukia is taken back to Soul Society, Sado and Orihime Inoue are trained by Yoruichi Shihōin to consciously call upon their powers when needed. After a week, Sado leaves for Soul Society with Orihime, Uryū, Yoruichi, and Ichigo. In Rukongai, Sado is reunited with Shibata, who has not yet found his mother but is living with a "family" of non-related people. At this point, Sado fulfilled his promise, carrying the boy on his shoulder for most of the day. Once entering Seireitei, the group becomes separated and Sado ends up alone. Sado easily fights his way through a fair portion of the Shinigami about Soul Society, and eventually finds his way into the quarters of the 8th Division. There he meets Shunsui Kyōraku, captain of the 8th Division, who makes a flashy appearance by having his lieutenant Nanao Ise sprinkle flower petals on him. After the flashy appearance, Sado proceeds to politely ask the captain to move out of the way as he would like to avoid fighting. Kyōraku sits down, telling Sado that he also dislikes fighting but cannot let him pass and asks if Sado would pull back instead. Upon hearing that Sado would not retreat, Shunsui offers him something to drink, something Sado responds to by an outraged "No" because it is illegal for minors to drink, something Kyōraku also realizes is a problem.

After hearing that other captains are also on the move, Sado tries asking Kyōraku to move aside one more time but is refused. Sado then attacks Kyōraku who simply redirects his energy blast with his bare hand. Sado launches a series of attacks to which Kyōraku easily dodges. Kyōraku tries to dissuade Sado by questioning him on his purpose and motives to continue fighting. Sado answers back, showing his determination and loyalty to his friend, Ichigo.

Realizing he is outmatched, Sado remembers his promise to Ichigo, and prepares to make a final move. As he runs towards the captain, Sado plans to hit him directly with a charged energy blast in his fist. Kyōraku however, having reluctantly drew his dual Zanpakutō, effortlessly defeats Sado, leaving him heavily injured. Nanao Ise notices that he is still alive and planned to finish him off but is stopped by Kyōraku because of the possibility of his involvement in the murder of Sōsuke Aizen, therefore necessitating keeping Sado alive for interrogation.

Following this, Sado, along with the rest of Ichigo's friends, does not actively participate in events. After being healed by the 4th Division and subsequently freed by Kenpachi Zaraki of the 11th Division, Zaraki's lieutenant, Yachiru Kusajishi, leads the group to the Sōkyoku where they wait as Ichigo and Byakuya Kuchiki fight. After Byakuya is defeated, the group tends to Ichigo. They then find out that the events at Soul Society were an elaborate plot masterminded by Sōsuke Aizen and confront him, but Aizen departs for Hueco Mundo. Uryū, Sado, Ichigo, and Orihime depart for the living world.

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

Sado greets Ichigo in class, and Mizuiro notices that Sado and Ichigo have gotten tanner. Keigo suddenly enters the class and gets annoyed that Sado and Ichigo have gotten closer, but Ichigo hits Keigo out of annoyance. When class starts, Sado, Orihime, and Uryū notice a Hollow outside coming towards the school, but it's quickly dispatched of by Ichigo.

Later at night, Sado finds Orihime training with her Shun Shun Rikka. Sado and Orihime talk, and Sado states that when he went to Soul Society, he thought he had finally found a chance to figure out his powers. Orihime states that she went because she wanted to be of use to Ichigo, but in the end she was useless. Sado tells her that she just has to keep trying, and explains that these powers of theirs were given to them by Ichigo. He states that if they're going to keep following him, they'll have to get stronger, and Sado fires off a blast of spiritual energy from his armored arm into a wall. Orihime remarks that that will cause a lot of attention, and this causes the two of them to leave. Later Sado wakes up and he senses something wrong with Orihime. He arrives at Orihime's house, along with Uryū, and he see's both Ichigo and Renji. He then sees Orihime being sucked into a gate and the gate disappears.

The next day, Sado and the others discuss what happened. Sado states that he can't sense Orihime's reiatsu at all, and Renji remarks that the gate she was sucked up in looked similar to the Gates Of Hell, but that there's no way the Gates Of Hell would take a living person. Sado states that the most confusing thing is what happened earlier, which was that none of their classmates remembered who Orihime was. Ichigo states that if someone is intentionally messing with their classmates memories, then that means someone is calculating their actions. The group then decide to investigate Orihime's house one more time.

Ichigo is unable to open the door to Orihime's house, so Sado decides to break in but Ichigo stops him. Uryū helps by picking the doors lock, and the group head into the house. After investigating a bit, they are able to come to the conclusion that Orihime invited someone inside her house. Renji suddenly gets a call and the person on the other line informs them that she knows of their location, and that she kidnapped Orihime. Ichigo asks for Orihime back but the person says that they first have to play a game with her. She gives them three challenges to pass, all of which involve going to various locations in Karakura Town in under three minutes, and answering the phone in that location. After passing the first two challenges, they are told to go to the Urahara Shop, and when they reach there they answer the phone and the girl tells them to head to Orihime's house at 8:00.

Later that night, the group stands in front of Orihime's house, and a bright light suddenly emits from Orihime's room. The door to the house is locked again, and this time Ichigo allows Sado to break the door down. However, the door ends up opening by itself, and a confused Orihime greets the group. Orihime is shown to have zero memory of what happened, and the group decides to stay with Orihime for a bit. As they wait, the lights in the house shut off and Orihime suddenly becomes possessed. She begins choking Sado, and she eventually lets him go. Orihime then transforms into a man and the person introduces himself as Kurōdo. He then brings out his partner Noba and the two of them take Sado into the same gate that Orihime was taken into.

Later, Sado is shown tied to a poll by Ririn, Kurōdo, and Noba just as his friends arrive to save him. However, Sado is used as a challenge stage for the group to go through; he is put into an hourglass and given 5 more minutes to live as sand begins rising in the hourglass. The group end up failing the challenge, but just before Sado is suffocated from the sand the hourglass breaks. Ichigo runs up to Sado to untie him, but Sado is able to easily free himself. Ichigo asks what happened while he was captured, but Sado simply remarks that there was tea. Ichigo suddenly realizes what is going on and he calls for Urahara to come out, claiming that he's the one behind all of this. Urahara does indeed come out, and it turns out that the entire time Sado was "captured" he was simply playing shogi with Ririn. After they all talk for a bit Yoruichi appears and informs the group of a new threat called the Bount.

At the Urahara Shop, Sado and the rest of the group are informed about the Bount. Urahara explains that they are a small group of specialized humans such as the Quincy, and that they are able to eat and absorb human souls and, in doing so, they can live forever. They normally consume the souls of the dead, however, Yoruichi notes that in the recent case, the Bount was trying to consume a living soul, which would effectively render the human dead. Out of concern for powerful human souls such as those of Ichigo, Orihime, and Sado, Urahara assigns each of the three mod souls to each of them, as each mod soul essentially has a secondary function as a "Bount sensor, and Noba is given to Sado. Urahara suggests that the mod-souls be put into stuffed animals, so Sado later buys a stuffed animal from a crane game, and then goes back home and puts the mod-soul into the stuffed animal. However, the two simply stare at each other, and Kon suddenly appears to yell at the two of them to speak. Sado asks him what he's doing here and Kon explains that Ririn has been bossing him around too much at Ichigo's house. Kon then suggests that they head over to Orihime's house to "save" her from the other mod-soul with her.

After arriving at Orihime's house they hear a scream and Kon suggests that they check it out, but Sado explains to him that peeping on others is a crime. However, he is forced to go in with Kon and they find Orihime screaming over how cute Kurōdo looks as a plushie. Kurōdo and Noba suddenly sense a Bount and they all head out to look for the Bount. After searching for a while they find a body on the ground and the body suddenly turns into dust. A Bount named Ryō Utagawa suddenly appears and informs the group that he was the one that killed the Human that just turned into dust. The Bount then leaves the area.

Sado and the others eventually find Ichigo, who was just confronted by two Bount, including the one that went up to them before. As Sado mentions their confrontation with the Bount, they notice that Rukia is with Ichigo as well and they greet her. They then change locations to talk and Rukia mentions why she was sent to Karakura Town again. Rukia then notices the mod-souls and Sado shows Noba to her. A bit later, the group heads to the Kurosaki Clinic, and they say that they're going to study together. They then head into Ichigo's room and they talk about the Bount and what they can do against them. Renji suddenly runs into the Kurosaki Clinic because Rukia is here, and they continue talking about the Bount. The next day at school Keigo offers Sado a ticket to Don Kanonji's show. However, a Bount is suddenly sensed in the area and Sado runs out of school with Ichigo and the others. They eventually run into the Bount Ryō and begin battling him. As Ryō explains his power and uses snakes to attack the group, Uryū appears to assist everyone but Ryō decides to go after the Quincy because of his current lack of power.

Ryō then holds a women hostage so no one can attack him, but Uryū offers to exchange himself for the women because he's the one Ryō wants. Ryō agrees to this, and after having his snake bind Uryū the Bount Yoshino Sōma appears and attacks Ryō. She then uses her doll to attack everyone else and she takes Uryū away from the area. After Orihime uses her Shun Shun Rikka to protect Sado and some others, the group decides to head after Yoshino but they're quickly stopped by Ryō. Ryō sends his snakes after them but Sado and the others easily take care of them. However, Ryō continues sending more snakes but they are quickly dispatched by Ururu, who has also appeared with Renji, Jinta, and Tessai. Ryō quickly runs away from the area and Ichigo decides to go after Yoshino, but they are unable to because she has gotten too far from them and the mod-souls can't track her reiatsu.

At the Urahara Shop, Sado and the others decide that they have to find Uryū, but Urahara informs them that if they do that then they would just be doing what the enemy wants. Urahara then explains more about the Bount to the group, but as he does this Tessai suddenly runs in and states that he got a message from Uryū. The group then quickly heads to the hospital and they find Uryū resting in bed. Sado checks to see if Uryū still has his legs to make sure he isn't a ghost but Uryū assures him that he's not. Uryū then explains what happened to him and what he learned from the Bount Yoshino, and that the Bount need the Quincy for some reason. Urahara then decides to leave to come up with a plan and Sado and the others decide to see him off.

The group then head back into Uryū's room and Sado and the others tell him to rest and that they'll protect him if anything happens. A bit later, Sado wonders why the Bount would need a Quincy, causing both Kon and Ririn to begin arguing about whether or not Uryū was mistaken. As night begins to fall outside, Sado remarks that there's no point in staying here if no enemies are going to attack. Later, Sado and the others try to fix a sink from overflowing and Sado remarks that it's most likely broken. Orihime then notices a noise coming from a room and she opens the door for it, only for water to flow out everywhere from it. The water eventually takes a mind of its own much to the shock of everyone and Uryū is encased in water and begins drowning. Sado tries to save him but he is unable to get rid of the water with just his hands. Ichigo then enters his Shinigami form, tells Sado to get out of the way, and uses his Zanpakutō to get rid of the water. They eventually realize that they can't stay in this room and all of them run out into the hallway.

Not long after leaving the group is confronted by more water and after taking care of the water, Orihime wonders if what's attacking them is a doll. The group then heads downstairs. However, they are immediately attacked by more water downstairs and both Sado and Uryū are encased in water, causing them to begin drowning. Renji swings his Zanpakutō to get rid of the water, but the water quickly encases the two of them again. After several more attempts, the two of them are eventually saved by Rukia firing off '''Hadō #31. Shakkahō''' with an incantation at the water. However, the Kidō spell caused an alarm to go off and the group begins running away. They then find a map and begin examining it to see where they can go, and they eventually decide to take the elevator. After running around a bit though, they are confronted by Hō and Ban, the two young Bount attacking them, and they summon their twin dolls to attack them.

The group immediately begins running away, and they eventually find the elevators they were looking for. However, water begins flowing out from the elevator, and everyone is forced to run away again. The group stops though and they are eventually able to get rid of the water. However, more water comes out of the surrounding rooms and the group quickly runs back to the elevator. Ichigo tells Sado to take Uryū and go on ahead and Sado does so while Ichigo and Renji stay behind to fight. Orihime, Rukia, and the mod-souls enter as well, and once they reach the bottom floor they quickly head out. However, the group stands in shock when they see it raining outside. Ichigo and Renji eventually appear to the group again and they're also shocked from seeing the rain.

Hō and Ban then reappear again and they decide to finish things up by combining the both of their dolls. Ichigo orders Sado and Orihime to take Uryū and get away from here, and he begins attacking the water. They begin to run away but they stop when they see Ichigo, Renji, and Rukia in trouble. Uryū tells Sado to leave him behind since he doesn't want to put them all in trouble, but Ichigo tells him to be quiet and tells the three of them to run away already. Orihime tries to object, but Sado tells her that Ichigo is correct and that he'll be okay. He states that their objective right now should be to just protect Uryū, and Orihime reluctantly agrees. They then begin running away again. As they run, Sado tells Orihime that they have to get out of this rain and they decide to head to a nearby factory. However, they are soon stopped by a large ball of water.

The water begins attacking them and Sado accidently drops Uryū, but before the water can attack Uryū Orihime appears and protects him with Santen Kesshun. However, the water breaks through Orihime's shield, and Hō and Ban inform them that they can't escape. Sado tells Noba and Kurōdo to protect Uryū and Sado activates his armored arm. Sado fires off a blast of spiritual energy at the water but it is unable to do any damage to it. Hō and Ban then send their doll after them and Sado continues attacking, but to no avail. Sado then attacks the two Bount much to their surprise, and they quickly move away from the attack. As Hō tells Ban that they have to stick together, Sado hits Hō with a blast of spiritual energy, and the water goes away because of this. Sado and the others then use this opportunity to quickly escape.

Sado and the others arrive at the factory, but Kurōdo points out that water is in here because the place is leaking. Sado simply apologizes and it's pointed out that it's better then being outside. Orihime notices that Uryū's fever is getting worse and Sado remarks that this isn't good. Hō and Ban suddenly reappear to take Uryū and they send water after the group. Uryū is grabbed by the water, and Sado tries to save him, but Hō and Ban tell him not to. They then begin strangling Uryū with the water as a demonstration to show what will happen if they intervene. As Sado wonders what to do, Ichigo and the others enter the room, and Hō and Ban decide to get serious. They have their water get on top of Sado's and everyone else's faces, and then have the water enter into their mouths and noses. This ends up causing the bodies of Sado and the others to be slowly teared apart from the inside out. However, they are soon saved by Noba who uses his powers to teleport the two Bount away from each other. Ichigo then saves Uryū and Sado holds onto him again. Hō tries to attack the group by himself, and he is successful for a bit until Ganju and Hanatarō arrive, and Ganju destroys the water with a firework. Because of the dolls defeat, the two Bount are destroyed as well. However, immediately following the battle the group realizes that Uryū is missing.

Sado and the others look for Uryū over the next couple of days. Eventually at night, the mod-souls sense two Bount as well as a trace of Uryū's reiatsu and they all head towards a rooftop. At the rooftop, they find no one but are able to deduce that two Bount were fighting over Uryū for some unknown reason. The group then eventually find out that the Bount live in a mansion, and they head to it. Sado and Orihime explore around the mansion, and they are shown being followed by some small round object. Later the mansion is attacked by Ururu, Jinta, and Yoruichi. Because of this, Uryū is rescued from the mansion, as well as the Bount Yoshino.

Sado later heads back to the Urahara Shop along with everyone else. After Ichigo and Renji train a bit, Sado gives the two of them coffee. However, Renji is confused as to what coffee is and has trouble figuring out how to make it taste better. A bit later, Sado and the others are informed that Uryū and has Yoshino have left, and they all decide to leave but Ichigo and Renji go on ahead due to Urahara's advice. Later the Bount form the bitto by killing Yoshino and performing a ceremony. Some time later at Karakura High School Sado mentions to Ichigo and the others that on the news it said that a lot of people have gone missing, and he speculates that the monsters that the Bount released may be behind this. After talking a bit more, Sado asks if there is any way for them to find the Bount and Rukia states that Urahara is currently making a stronger sensor. At night, Sado is shown outside with everyone else and they all decide to split up into small groups to look for the Bount. Sado and Noba are put together, and they begin searching for the Bount.

Sado encounters Sawatari and fights him along with Rangiku Matsumoto, Noba, and Ururu Tsumugiya. The battle ends undecided.

After the Bounts invade Soul Society, Sado meets up with Ichigo to fight Jin Kariya. However, the fight doesn't last very long, as their battle reveals the massive energy source Jōkaishō, which Kariya absorbs and uses its potential destructive power as a threat to keep them at bay.

Arrancar arc
After returning from Soul Society (for a second time in the anime) Sado's life returns to normal. He is first seen back in school along with Orihime and Ishida. He says hi to Ichigo and Keigo is confused as to why they're all friends. Later when Ichigo's Substitute Shinigami Badge goes off Sado asks if it's a Hollow. Ichigo leaves school to fight the Hollow and Sado follows along with Orihime with the excuse that they have to go to the bathroom.

Ichigo defeats the Hollow easily and he tells Sado and Orihime that they didn't need to come. Ichigo then asks why Ishida didn't come and Sado notes that he's more concerned about Ishida not showing up when he wants him to. Orihime says that Ishida isn't doing well and Ichigo asks Sado if he noticed anything and he says no. Orihime then states that he doesn't want Ichigo to know things like this and Ichigo points out that she shouldn't have said anything then. Orihime is worried about this and Ichigo says they'll just pretend they didn't hear anything.

Sado is later shown in class again and when Ichigo's Substitute Shinigami Badge goes off again and he leaves, Sado tells the new transfer student, Shinji Hirako, that that's just how Ichigo is. Shinji tells him that he pretty much expected him to be that way.

After school is over Sado is shown walking around the streets at night.

When Ichigo drags Shinji out of class Sado is shown with a serious look on his face.

Sado and Orihime later interrupt a fight between Shinji and a young girl. The young girl notices them and gets mad at Shinji for getting followed. Orihime asks Shinji what he wants with Ichigo and the young girl tells her that they won't say anything. The young girl then introduces herself as Hiyori Sarugaki and she tells them to introduce themselves as well. They do and Hiyori points out that their names mean princess and tiger and is jealous since their names mean Monkey and Hira. Shinji gets mad that he's the only one who doesn't get to be a living thing and tells her not to include him if it doesn't make sense, and Hiyori responds by hitting him. Hiyori then states that she's going to kill them and Shinji grabs her and runs away. Orihime attempts to go after them but Sado stops her stating they would never be able to catch up to them with their speed and even if they did they would get killed anyway.

Sado and Orihime later sense an enormous spiritual pressure around the area. They run to where it's coming from and Orihime attempts to help someone on the ground but Sado notes that the person is already dead and that the people around them have had their spirits pulled out of their bodies. Sado then asks Orihime that if there are any survivors that she should save and run away. Orihime notes that he'll be alone but Sado tells her she has to do this since he can't heal anyone.

Sado arrives and blocks a kick that was meant for Tatsuki from a giant Arrancar named Yammy. Sado thinks to himself that this is too dangerous for Orihime and tells her to run away with Tatsuki. Yammy yells at another Arrancar named Ulquiorra and asks if he's "the one". Ulquiorra states that he's trash and Yammy attacks Sado causing his armored arm to break in half. Sado then falls down unconscious.

Sado is later shown looking out of a window and healing from his injuries. He decides to get up and leave but a nurse tries to stop him since his treatment isn't done yet. He leaves anyway and is immediately confronted by a lone Arrancar called Di Roy Rinker. He goes to stab Sado's chest claiming that he has lost but Ichigo grabs his arm and tells him that the winner is determined after the actual battle. Sado realizes that he would have died if Ichigo was even a second slower and Ichigo tells him to run away. He does so and as he's running Rukia spots him and is glad to see he's okay, but Sado simply runs past her and thinks to himself that he'll never be able to help Ichigo anymore.

Sado goes to the Urahara Shop and begs Kisuke Urahara to train him when he realizes he is too weak to protect anyone. Urahara initially refuses but then decides to have him fight against Renji Abarai and has Renji continually use his Bankai against him.

Hueco Mundo arc
When Orihime is captured by Sōsuke Aizen, Sado and Uryū offer their services to help Ichigo rescue her. When Ichigo hesitates, Sado demonstrates the power of his improved arm, quelling any fears he might have had. The trio then depart to Hueco Mundo. Upon their arrival, Uryū and Sado engage two Arrancar named Aisslinger Wernarr and Demoura Zodd, telling Ichigo to watch them. After initially struggling against Aisslinger, Sado switches opponents with Uryū and easily defeats the slower and less intelligent Demoura with his new attack, El Directo.

After making their way to Las Noches, joined by Rukia, Renji, and a group of friendly Hollows, the group splits up and Sado eventually runs into the Privaron Espada Gantenbainne Mosqueda. Initially outmatched by the former Espada, Sado is severely beaten around until he realizes what his powers truly are alike and reveals to Gantenbainne that ever since coming to Hueco Mundo his powers have been uneasy but taking the beating from him has calmed them down. Revealing a third form of his arm, he calls it Brazo Derecha de Gigante, saying that it is the true form of his right hand.

Sado is finally able to keep up with the Arrancar and begins giving Gantenbainne a beating. Gantenbainne however releases his Zanpakutō and thinking he has the upper hand attacks Sado with a huge energy blast. Sado however reveals the true armor form of his left arm, calling it Brazo Izquierda del Diablo and easily blocks it. With his true powers finally awoken, he easily beats Gantenbainne with a new attack, "La Muerte", in turn also crushing the armor of his release form. He thanks Gantenbainne for helping him grasp his power by fighting with his full strength and decides to spare him. His victory is short-lived, however, as the 5th Espada, Nnoitra Gilga, severely wounds him and leaves him for dead. To Nnoitra's surprise however, Sado manages to get back up, gravely wounded, and attempts another attack but he collapses after being stopped by Nnoitra's Fracción, Tesra Lindocruz.

Sado and Gantenbainne are eventually found by the Exequias, who plan to finish them off, but Retsu Unohana and Isane Kotetsu interrupt. He later attacks the Exequias who are fighting Ichigo along with Renji and Rukia.

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.

Fake Karakura town arc
Sado is seen fighting Hollows alongside Renji. He comments after Renji complains about the number of Hollows saying, "let them come." Later, the Hollow Battikaroa emerges and gives Sado and Renji a hard time with his Cero and instant regeneration. Though Sado constantly annoys Renji with his quiet nature, in the end, the two finally learn how to work together and kill Battikaroa by Sado using his La Muerte to distract the Hollow and Renji finishing him off for good with his Bankai.

Later, as Sado and Renji continuously destroy more Hollows, both of them notice Yammy, along with Rukia coming down from the ceiling and Sado doesn't recall Yammy being such a giant. The group then notices Ichigo's spiritual pressure. He, along with Rukia and Renji, sensed Ulquiorra's spiritual pressure fading away from the dome of Las Noches and wonder what has happened. The group look at an enraged Yammy, who Sado says is a lot bigger than when they last met. The group then judges that Yammy is the 10th Espada. Upon noticing this, Renji tells them that together they can defeat him because he is #10, but upon hearing this Yammy decides to release his Zanpakutō. Sado, Rukia, and Renji realize in shock that Yammy's number changed into #0. Now transformed into a giant monster, Yammy says that the ten Espada are ranked from 0-9 and introduces himself to them as Espada Zero, Yammy Llargo. Sado is later seen on the ground unconscious, having obviously been knocked out by Yammy.

Sometime after Aizen is sealed away by Urahara, Sado arrives along with Uryū, Orihime, Rukia, and Renji to the Soul Society. Sado's left arm and head are bandaged as the group greets Ichigo. When Ichigo suddenly collapses, Sado, Uryū, Renji, Rukia, and Orihime run toward him and find him screaming. Later, Sado along with Orihime, Uryū, and Rukia, are by Ichigo's bedside as he wakes up. Rukia explains he's been unconscious for a month and details the loss of his Shinigami powers. Sado along with the rest of the group is present to see Ichigo's farewell to Rukia as she fades from Ichigo's sight once his spiritual energy disappears.

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

Muramasa arrives in Karakura Town after learning that his master was sealed there. Sado and Uryū arrive after Orihime heals him. Sado and Uryū both fight Muramasa together, but Senbonzakura interrupts the fight and separates Uryū from the battle. Muramasa subsequently invades Sado's mind and manages to subdue him. Sado later recovers to fight off Muramasa's Hollows in order for Rukia to go after Muramasa. When Muramasa transforms into a Hollow and goes on a rampage, Sado goes to protect his friends, his armored arm barely able to repel Muramasa's attacks. When Muramasa's power rises again by drawing in more Hollows, Sado joins Uryū in destroying the Hollows.

As Ichigo continues to fight Muramasa, the rogue Zanpakutō goes through another transformation; this time into a dome-like structure that engulfs Ichigo. While Sado and his friends are unsure what to do, several Shinigami arrive to help. After the Shinigami destroy the hollows and Muramasa's dome collapses, Ichigo emerges with a defeated and dying Muramasa, who apologizes for his mistakes before fading away.

The Lost Substitute Shinigami arc
Sado is led to Xcution by Riruka Dokugamine. As she complains about having to find Sado, she begins to get annoyed at Sado for not speaking. Sado simply remarks that he is amazed that Riruka could talk for so long, and Riruka begins to get more annoyed. Sado eventually reaches Xcution but when he gets there he immediately spots a shocked Ichigo sitting in front of him. Chad is just as surprised to see Ichigo there but does not respond to Ichigo's questions. Kūgo asks them both to sit quietly as he explains things. He says every Xcution member had their mothers attacked by Hollows while they were in the womb, leaving traces of their powers which were then passed to the children as they were born. The members of Xcution wish their powers gone and have discovered that they can erase them by transferring them onto a Shinigami-Human hybrid. He says Chad also has Fullbring powers and has agreed to help restore Ichigo's powers. Ichigo asks Chad if that's true and he approves it, saying he hasn't been able to look at Ichigo since the latter lost his powers. He tells Ichigo not to try and hide his passion to fight for others' protection. After hearing this, Ichigo agrees to help.

When Sado returns to the hideout with some shopping, Giriko thanks him. He asks what the box on the table is and Jackie tells him that it is Riruka's doll house, inside which Ichigo is doing his Fullbring training. He is stunned by this and Riruka tells him that it is better to start quickly. She asks if he is going to join in the complaints against her way of doing things. Sado removes the roof of the house and tells Ichigo to that his substitute Shinigami badge is the best thing he can think of to use for Fullbring.

Powers & Abilities
Superhuman Strength: Sado possesses a remarkable amount of superhuman strength for a human. He was capable of lifting a steel beam that had fallen on him with little effort. He can effortlessly throw another person a half a block away with only one arm. Sado was able to battle a Hollow with his bare fists and is strong enough to break a telephone pole and swing it like a bat. He was able to effortlessly throw off the Hollow creature helpers of Shrieker. His strength is further enhanced with his armored arms, allowing him to take on those bigger than himself with relative ease as a single punch he was able to take left arm off the Hollow, Bulbous D. He has also show enough skill to aid himself in a safe descent to the ground when falling from high above with tremendous force. He is so strong that he was able to effortlessly punch a 3rd Seat Shinigami, sending him flying away half a block, defeating him. His strength is such that he could punch a large Arrancar in the face, shattering his mask remnant and send him flying a good distance. He effortlessly staves off a punch from Demora and throws the massive Arrancar. In its true form, his right arm is powerful enough to take on a former Espada and send him flying a great distance through a wall and giving him a considerable injury. With his left arm, he is powerful enough to stop and crush Gantenbainne's most powerful attack.

Enhanced Durability: Sado is unnaturally highly resistant to damage. He was able to withstand a falling steel beam, which bent upon contact with his back, with minor injury but relatively unfazed. He was able to take a head-on collision with a motorcycle; while the driver was seriously injured, he walked away with only minor injuries. He was able to sustain a clawed attack to his back by the Hollow Shrieker, that would have been fatal for anyone else. When his arms are armored, he seems to attain an even greater level of endurance, allowing him to take relentless beatings as well as being thrown into structures without showing any signs of injury. His durability also becomes great enough to block incoming attacks and blasts. He is also shown to be highly resilient mentally, able to endure a powerful attack to his psyche and continue fighting. In its true form, his right arm is durable enough to effortlessly block attacks from a former Espada.

Spiritual Awareness: After his encounter with the parakeet containing the soul of Yūichi Shibata, he started to detect the approximate locations of spirits and Hollows, but could not fully see them. Only after saving Karin Kurosaki from a Hollow, during the Hollow-slaying match between Uryū and Ichigo, did Sado begin to fully see spirits.

Enhanced Speed: Sado's speed is above that of an average human being. The recent furtherance of Sado's powers seem to augment his natural agility to the point where his reaction time became sufficient enough to anticipate high-speed attacks and counter them. During his fight with Gantenbainne, Sado develops a level of speed that can easily keep up with that of Sonído, even capable of appearing behind his opponent and attacking.

High Spiritual Power: He commonly uses spiritual energy to augment the strength of his punches. During his basics training in spirit energy with Kūkaku Shiba, Sado was shown to have intensely strong and high levels of spiritual energy, though the Shiba Clan cannon orb was unstable. Ever since coming to Hueco Mundo, Sado felt that something about the power inside him was different than when he was in the human world. He was confused by that and up until his fight with Gantenbainne Mosqueda, his power had eluded him. But after that he was finally able to grasp it, and was from then on, he was able to fight with his full strength. Ever since he came to Hueco Mundo he had felt the power inside him rustling, something he never felt while in Soul Society. The resulting increased the deeper he went into Hueco Mundo and it was the beating he recieved from Gantenbainne that caused the rustling to settle down. Upon coming to Hueco Mundo, his power has been happily crying out like it had come home and through the violent welcome, of its brethren reclaimed its sanity. Sado acknowledges that his power is less like a Shinigami's or Qunicy's and more like that of a Hollow. This allowed him to fully tap his powers, which manifests as armor on both arms, instead of just his right.

Expert Hand-to-Hand Combatant: While never officially trained, Yasutora Sado has shown himself a powerful fighter even when outnumbered.

Fullbring
(Brazo Derecho del Gigante in the English dub and English manga). Due to the abundance of Ichigo Kurosaki's spiritual energy and his lack of actual control over it, said spiritual energy wildly pours out. That poured out spiritual energy is so thick that it can affect every single spirit. By encountering the spiritual form of Ichigo Kurosaki constantly, Sado's natural powers were pulled from the depths of his soul. Later, it is revealed that this power is actually a product of Fullbring. Sado claims that when he first used his power it was because pride was in his heart (which was his abuelo) and the object that acted as the source for his fullbring was the skin on his right arm.


 * First Form (formerly): He covers his right arm all the way up to his shoulder in a liquid which then solidifies into a form of armor. The shoulder fans out a bit into an upward extension parallel to his height. It has an indentation at the top in the middle of the extension stopping just where his shoulder begins separating the upward extension into two. There are two wing-like protrusions on either side of his wrist. The arm is black with a dark magenta strip running down the middle of the arm tapering down towards a point that stops at the wrist. The dark magenta strip is outlined by a thin white line. These patterns are both on the top as well as the underside of his arm.


 * Spiritual Energy Blasts: He is able to fire powerful energy blasts from his fist. After receiving advanced training from Yoruichi Shihōin, Sado learns to activate his powers at will and gains sufficient stamina to fire multiple blasts. These spiritual energy blasts have become more powerful with each form taken. He is able to fire them effortlessly. Sado is able to gather energy through the shield portion of his right arm and fire it in the form of a powerful massive energy blast from his arm. This power works in all forms.


 * Second Form: He covers his right arm all the way up to his shoulder in a liquid which then solidifies into a form of armor. The shoulder extension becomes pointed as well as slightly longer, making it a little bit taller than Sado. The arm maintains its black color, but the magenta becomes slightly lighter and the design becomes more intricate, while the white is lost altogether.


 * A powerful special attack learned upon attaining the second form. The ends of the extension on Sado's shoulder opens up and charges up spiritual energy, appearing somewhat like the flaming exhaust from a car engine, and then he releases a huge blast of spiritual energy that he can use to augment his punches or simply as a concentrated medium to long-range attack.


 * True Form: He covers his right arm all the way up to the shoulder in a liquid which solidifies into a form of armor. Brazo Derecha de Gigante becomes a shield that extends from his hand to some distance beyond his forearm with the same intricate pattern as before, surrounding what appears to be Hollow-like teeth in the center and what appears to be a rose like pattern or skeletal nose and eyes near the end. He also loses the wing-like protrusion which extended from his shoulder, replaced with an hexagonal plate sitting over his shoulder. In this form, it is used for defense instead of offense (though it's still more powerful offensively than his original arm). This is the true form of his right arm and its true power. Sado says that "the soul of his Abuelo flows through his right arm," speaking metaphorically of his grandfather's teachings. What his abuelo taught him was to protect and that is why what dwells in his right arm is a defensive power.

(Brazo Izquierdo del Diablo in the English dub): He covers his left arm all the way up to the shoulder with a liquid which solidifies into a form of armor. The arm is white, with a red stripe running down the length of the center. His fingertips of red diamond shaped marks on them. A spike protrudes from the shoulder and two more resembling claws extend over his chest. This is the offensive power within him.


 * (El Muerte in the English manga): A powerful special attack. His finger tips charge in the forms of five disks of crackling spiritual energy, then he forms a fist and punches his opponent. The blow is devastating and upon contact, a huge skull-shape is created upon the surface behind the target. The power can easily defeat a Privaron Espada, and is most likely Sado's strongest attack, as it comes from the arm formed from Sado's will to attack, rather than defend.

Ichigo Kurosaki
Sado is one of Ichigo's best friends. They first met when Sado saves Ichigo from being beaten. They also once fought together against a group of bullies, and after that, promised to protect and help each other in any situation that calls for it. Ichigo mispronounced his name wrong as "Chad" instead of Sado when they met, but he continues to call him Chad afterwards. Sado has shown that he is willing to help Ichigo in any situation, even after Ichigo received his Shinigami powers. When he is attacked by Di Roy Rinker, Ichigo saves him, but Sado feels that he is not strong enough to help Ichigo and resolves to get stronger after this by training under Kisuke Urahara.

Orihime Inoue
Orihime and Sado have a somewhat strong relationship. When he first fought Yammy Llargo, knowing that he could not defeat the Espada, Sado told Orihime to hide with Tatsuki in order to keep her away from the fight. When Sado is defeated, Orihime returns to heal and protect him. When Urahara attempts to remove Orihime from the front lines, Sado strongly objects to this, saying that she has been very helpful and that her healing and defensive powers are vital to them. Sado's relationship is also shown in the Zanpakutō Unknown Tales arc, when she worries for him when he passes out from Muramasa's ability.

Oscar Joaquín de la Rosa
During his early years, Chad was extremely violent; exploiting his advantage in size, he intimidated and hit any other children who annoyed him. Oscar Joaquín tried to teach Chad to be gentle, but was initially unsuccessful. One day, the fathers of the children Chad fought, seeking to punish him, attacked Chad. Oscar Joaquín stepped in between them, taking Chad's punishment without retaliation. Chad was inspired by this example to become a decent person. Afterwards, Oscar Joaquín gave Chad a Mexican coin.

Censorship
Sado's injuries from his first encounter with Yammy Llargo were drastically toned down in the anime. In the manga, his armored arm was literally torn off and broke into two, while in the anime, his arm merely had several deep cuts in it.
