Masataka Kiyomizu (
Kiyomasa is a relatively tall and muscular teenager that looks older than his age. His prominent feature is a scar upon his left eyebrow. He has black hair that is stylized in a small pompadour, slanted, menacing eyes and looks more of an adult rather than a teenager. He wears Shibuya's uniform, which is a dress shirt, black slacks, and loafers. He is also shown to smoke.
Kiyomasa is a merciless and cruel individual, who brutalizes those he considers below him. He is not hesitant at all to assert his dominance upon the weak and use them to fulfill his thirst for violence and means.
When challenged or when otherwise annoyed, Kiyomasa can become incredibly more brutal at times often resorting to use a bat to beat the target of his scorn to an inch of their lives. This can be seen when Takemichi Hanagaki asked to see Sano, Kiyomasa does not want to hear that name coming from his underlings for some reason. Incredibly arrogant to a fault, when Mikey and Draken appeared during his fight in his own fighting ring, he never bowed down to either of them, despite knowing in full who they were, and had to be forced to bow by Draken. The severe beating and reprimanding that ensued for making a clandestine fighting ring imply that he acted without consent from his superiors, therefore attributing himself an authority that he never had in the first place.
He is also shown with a vengeful streak, as seen when he gets manipulated into attempting to stab Draken to death out of spite for humiliating him earlier.
