Aside from being a man in his late twenties, and wearing glasses, much of Mitsuzō's description is unknown. Given he is related to Takaya, it is likely he also had light brown hair like his younger brother. Compared to his younger brother, Takaya, Mitsuzō is much more cowardly, quick to panic, and outwardly selfish, being utterly scared from the killings that happened during the championship and wanting nothing more than be rid of them for his own safety.
