Synopsis
While searching for his sister, Shōta is attacked by an Arrancar. While running away, he meets Rangiku Matsumoto, who protects him from the unknown Arrancar. After the Arrancar is defeated by a timely arrival of Ikkaku Madarame, Rangiku prepared to perform Konsō on him, but is stopped by Tōshirō Hitsugaya, who decides to bring him along for questioning. After arriving at Orihime's apartment, Shōta is asked as to why he was being chased, and if he knew the source of the mysterious sound they had heard earlier. When Hitsugaya concludes that his attack was no more than a coincidence, he prepares to perform Konsō. Seeing this, Shōta tells him that he cannot go as he still has something he must do. Compelled by his plea, Rangiku asks her Captain to at least let him stay for the night. After everyone had gone to bed, Shōta takes Rangiku's Zanpakutō and runs off, but then he is stopped by Rangiku who scolds him for both taking her sword and referring to her as "old lady". Just then, the two hear the same sound and Rangiku feels the same Reiatsu of the Arrancar they had defeated earlier.

Rangiku decides to go investigate the source of the sound and Shōta goes along with her. The two encounter the same Arrancar Ikkaku had defeated earlier and Rangiku asks that he stay behind. Shōta throws rocks at the Arrancar, but is blasted away by an energy attack from the Arrancar. As he flies away, he is caught by Captain Hitsugaya. Shōta and the two Shinigami then watch as many more copies of the same Arrancar begin to show up. Shōta is carried by Rangiku as the three try to find a place with more room to fight, which prompts Shōta to suggest the park at which they first met. Having enough room, Shōta witnesses as Hitsugaya's Shikai defeats all the Arrancar copies at once. While the group compare notes, Shōta wanders off and finds his sister Yui Toyokawa seated seemingly asleep at a bench in the park. That night at Orihime's apartment, Shōta tells Hitsugaya and Rangiku about he and his family's death, as well as telling them that his sister was who he was searching for. As Hitsugaya was about to ask Shōta a question, they received a transmission from Jūshirō Ukitake and Akon who have information about the Arrancar they had fought. As the group leaves to investigate the Arrancar, Ragiku stays behind to watch over the reunited siblings. With Yui asleep, Shōta is asked by Rangiku if he was hiding something, which he denies. Just then, the two hear a tumbling sound and as they look, Yui has disappeared. Shōta runs towards the park once again, with Rangiku chasing after him. As the reach the park, Rangiku tells him that they will take care of finding his sister, but he insists that he must protect her. As he turns around, he sees his sister seated down at swing in the park. Shōta asks Yui why is she there and she merely responds that she just wanted to go to the park. Shōta then breaks in tears of frustration as he confesses to have run off and left her behind. With some words of encouragement, Shōta is able to compose himself again.

Back at the apartment, Hitsugaya and Rankgiku compare notes about what they had found out. As Rangiku suspects Yui, Shōta steps in a denies her claims. Shōta attempts to protect his sister from Hitsugaya as the latter performs a Konsō on Yui to no effect. With the Shinigami considering Yui to be a possible threat, Shōta stands by his sister as Soul Society's Shinigami Research and Development Institute runs tests on her. Hitsugaya tells them Yui will need to be put inside a barrier, but Shōta objects, claiming that she doesn't deserve such treatment. Rangiku manages to convince Yui to by giving her a small ocarina, and with Yui's agreement, Shōta decides to comply as well. As Shōta keeps watch over her, he remembers the time they spent together looking for their parents. As Yui awakens, she asks him to let her go outside and gets Shōta to help her in break the Kidō barrier that had been placed. Having arrived at the park once again, Rangiku confronts the siblings and ask how were they able to break the barrier, to which Shōta brags about how easy they were able to do it. Yui, after seeing Rangiku's interference, releases a huge amount of Reiatsu, causing multiple clones of the Cloning Arrancar to appear. Shōta, confused by the situation, finds himself being forced to walk toward his sister. Shōta begins to scream Yui's name, waking her up and releasing her from the Arrancar's control. While momentarily in control of herself, Shōta watches as his sister yells at him to stay away.

Shōta runs toward his sister, but she pushes him away to protect him as the real Cloning Arrancar appears. Shōta watches as his sister transforms into one of the clones and the rest begin to attack him. Matsumoto begins her fight against the real body of the Arrancar. Shōta gets surrounded by clones of the Arrancar and is saved by a timely attack of Hitsugaya's Hyōrinmaru. As the three confront the Arrancar, he tells them that if he dies so will Yui. Shōta, upon hearing this, stands between the Arrancar and Hitsugaya, but Hitsugaya merely replies that what is one soul compared to an entire town. Using the distraction, the Cloning Arrancar hides away and sends a horde of clones against them. In an attempt to calm Shōta down, Rangiku explains to him that Hollows are fallen souls and they must be slain by a Zanpakutō in order to cleanse their souls. She then tells him that while they weren't able to save his sister's soul, they can still save her. The three set off to where the real body is hiding and while Hitsugaya tries to find where the real Arrancar is hiding, Shōta pleas to his sister to tell him where she is. Upon hearing the sound of his sister's ocarina, Shōta is able to tell where the Arrancar is hiding. Shōta watches as Hitsugaya's Bankai overpowers the Arrancar's Resurrección. With the Arrancar immobilized, Shōta, along with Rangiku, uses Haineko to deliver the finishing blow. Shōta digs the ground and finds his sister's original ocarina. With the ocarina in hand, he asks Rangiku if his sister made it to Soul Society, to which Rangiku says that she guarantees it. With this in mind, he tells Rangiku that he needs to catch up to Yui, which results in Rangiku performing a Konsō on him.

Yui Toyokawa
Shōta had the average sibling relationship with his sister Yui when they were alive, such as teasing her like any big brother would. When they died, they stuck together like glue as they searched for their parents. At time, yui began to give up but Shōta always encouraged her not to lose hope. One night however shattered their lives as a strange monster appeared. Yui called to Shōta, begging for his help, but Shōta, frightened to his very core abandoned her, and when he was reunited with her, she still believed in him, making him feel even more ashamed. When the horrible truth was uncovered, Shōta wanted to save her, and with Rangiku at his side, he succeeded and departed to Soul Society to truly be with Yui.

Rangiku Matsumoto
Initially, Shōta didn't trust Rangiku and disrespected her by calling her old. He even went so far as to try and steal her zanpakutō. But little by little, Shōta and Rangiku developed a trusting bond comparable to that of a younger brother and older sister. Rangiku comforted Shōta when he explained what had happened to him and Yui, and encouraged him to not give up on Yui. Their friendship was sealed when they destroyed the Arrancar that had taken Yui, and they gave each other a loving farewell when Rangiku performed the Konsō on Shōta, sending him to Soul Society to truly be united with his sister, but not before promising to each other they would be friends forever and they would see each other again.
