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. 
Added by GojitaAfter 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.[10] 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[11].

Bount arc (anime only)Edit
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.[14]
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.[14]
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.[15]
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.[15]
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.[15]
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.[16]
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.[17]
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.[17]
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.[18]
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.[19]
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.[19]
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.[20]
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.[20]
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.[20]
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.[21]
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.[21]
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.[21]
Added by Prophet of SangheliosAfter 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.

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.

They do and Hiyori points out that their names mean princess and tiger and is jealous since their names mean Monkey and Hira.
