Zeta

As a young woman she never expected to be brought into the yakuza. And worst yet it’s to be a baby sitter to a man who is crazy. But it was the order Mikey had given her. And she would never go against his words.

As a teenager, Haruchiyo has a calm demeanor and rarely talks. He was extremely loyal and much nicer to those he follows and worships. However, it is later revealed that he is also quite manipulative and is exceptionally good at deceiving other people. As an adult, Haruchiyo seems to be more extroverted, blunt, and loud. Similarly, he resembles Joker. He is ruthless and displays psychopathic tendencies. It’s implied this is caused by the drugs he takes, which provokes his rather maniac personality. He takes sadistic delight and notorious euphoria when executing traitors, while voicefully stating he is enacting Mikey's will. When encountering Takemichi, Haruchiyo ordered him to be silent for the "king" would speak, and threatened to shoot Takemichi for his casual approach, believing it a disrespect. Haruchiyo’s most notorious trait is his fanatical idolatry towards Manjiro Sano, believing Mikey to be his "king" (akin to the Chess King), and thus deserving of the utmost respect, loyalty and devotion. He is so inclined towards protecting Mikey or the image of him, that he assaulted a gang by himself when they were badmouthing Toman.
