Moe Shishigawara

is a high school student from Miyashita Commercial High School. He works under Shūkurō Tsukishima.

Appearance
Shishigawara has a shaved head, which is slightly longer in the middle. He wears his high school uniform with his jacket open.

Personality
Shishigawara is rather cocky, having a lot of confidence in his ability to fight. However, he seems to have trouble fighting girls he finds pretty, as he is almost unable to bring himself to fight Orihime after looking at her and finding her to be pretty. Shishigawara is loyal to Tsukishima to the point where he does not mind laying his life on the line in order to fulfill his duty to him; he is even able to overcome his reluctance to fight girls in order to prove himself useful to him. Shishigawara is also stubborn, as while he is loyal to Tsukishima, he refuses to withdraw after being told to do so by Tsukishima himself.

The Lost Substitute Shinigami arc
Shishigawara is given the assignment of defeating Orihime Inoue by Shūkurō Tsukishima. Upon noticing that he was given a female target, Shishigawara is intrigued. Noticing his reaction, Tsukishima tells him that he does not need to do anything because he believes that he will not attack girls. Shishigawara denies this and heads off to fight Orihime anyway. He finds Orihime outside of her apartment and introduces himself to her while she is distracted. He casually asks her if she minds dying.

Determined to prove himself to Tsukishima, Shishigawara plans to defeat Orihime in one hit. However, once Orihime turns around, Shishigawara is overwhelmed by her appearance, which knocks him onto the ground. In his thoughts, he remarks that she is beautiful and he is unable to focus on his assignment. He attempts to look at her again, but is still amazed at her appearance, which causes him to momentarily resign from his task. However, once he remembers Tsukishima's orders, he stands back up, believing that Tsukishima believes that he can fulfill his assignment. He tells Orihime that he has come to kill her, but she does not react to this. Amazed that Orihime apparently does not understand the threat, he repeats that he is going to kill her a couple more times before remarking that he took out Uryū Ishida. Orihime's expression changes upon hearing this, and she questions if what Shishigawara says is true. Seeing her angered expression, Shishigawara is able to focus on fighting her completely, and answers that the fact that he has mentioned it is proof enough. Orihime agrees, but she wants to know more about where he is from. Shishigawara tells her that she has to force it out of him if she wants more information. However, Tsukishima arrives, stopping their fight from starting, and says that he was the one who attacked Uryū.

Tsukishima introduces himself to Orihime, but Shishigawara interrupts them, saying that Tsukishima did not need to come out and waste his time on her and tries to goad her into fighting him again. Tsukishima tries to get Shishigawara to withdraw, but he refuses, saying that as Tsukishima's underling, Tsukishima's reputation is more important than Shishigawara's life. Tsukishima closes his book and reminds him that he told him that he did not need to do anything. Shishigawara remembers him saying that, which causes Tsukishima to ask him why he is still there. Shishigawara tells him that he wants to be useful to him. Tsukishima pulls his bookmark out of his book and casually remarks that he forgot which page he's on. He transforms his bookmark into a katana and asks is Shishigawara if he minds taking responsibility for it. Orihime asks if his sword is a Zanpakutō, but Tsukishima tells her that it is not; it is actually his Fullbring, Book of the End. He tells Orihime to relax, as he does not plan to harm her at this time; instead, he is going to punish of Shishigawara, who cannot follow his orders and then leave. Orihime then blocks him from Shishigawara, which causes Tsukishima to remark that she does not like seeing enemies get hurt. Orihime denies this, stating that since he attacked Uryū, she cannot let him leave. As Tsukishima taunts Orihime's statement, Shishigawara tries to warn her, saying that Tsukishima will do more than kill her now; however, Orihime just tells him to be quiet. As Tsukishima turns to leave, Orihime tries to activate her Santen Kesshun to stop him. However, Tsukishima suddenly appears behind Orihime and stabs her from behind, much to Shishigawara's shock.
