However, it was revealed that he was actually involved in the case of the murders of Uruma's family from the beginning, showing that he wanted to prevent Uruma from becoming a copy of the people who tormented him.

possible. He is also shown to be concerned and shocked when he witnessed Uruma's murder of Kuga. Rather than planning on prosecuting him, he hoped that Uruma didn't kill Kuga, as doing so would turn the young teenager into a monster himself.

Trivia

 * So far, Anzai is the only person that Uruma murdered to not be a bully, but also to be innocent.
 * Anzai's motives behind offering his hand to Uruma in Chapter 58 is left unknown, as he may either try to help Uruma redeem himself or is possibly tricking him into going to jail.
 * Anzai's initial appearance contrasts that of Jun Shirakawa, one of Uruma's classmates. While Anzai was initially portrayed as an antagonistic character before the reveal of his true nature, Jun would initially be a friendly-turned-antagonistic character towards Uruma later on as the former believed that the latter had traumatized his sister.
