Akashi Haruchiyo (Sanzu)

Tokyo's most dangerous criminal organization is Bonten. Bonten's leader is Mikey Sano.

Haruchiyo appears to be more extroverted, straightforward, and loud. He is ruthless and exhibits psychopathic tendencies. Haruchiyo also took a lot of drugs, which is believed to have played a large role in his insane behavior and personality change.
Haruchiyo's most notable trait is his fanatical idolization of Manjiro Sano, considering Maiki to be his "king" (akin to the chess king) and thus deserving of his deepest respect, loyalty, and devotion. He is so protective of Maiki or his image that he single-handedly attacked a gang when they were insulting Toswa. He also came to Muchou when he was released from prison, solely to kill him for betraying his king, going so far as to brutally kill him so that no trace of him would remain.
He currently experiences sadistic pleasure and the notorious euphoria of executing traitors, while loudly stating that he is carrying out Maika's will. When meeting Takemichi, Haruchiyo ordered him to remain silent, as the "king" would be the one speaking, and threatened to shoot Takemichi for his casual approach, considering it disrespectful.

Haruchiyo may seem like a calm and reliable person, but he is actually very manipulative. He was able to manipulate Muchou for a very long time and killed him after he betrayed his king Manjiro Sano.

Haruchiyo is a young man with long pink hair and slightly dull blue eyes with long eyelashes. He has a similar appearance to his younger sister, Senju Kawaragi. He is usually seen in his Toswa form, wearing a black mask and a deadpan expression. He has a number of piercings in both of his ears, including two helix piercings and two earlobe piercings, for a total of at least four piercings on each ear.
