So quiet that Rindo worries if he's even breathing. He remains silent even when crushing an opponent. He never speaks more than necessary. Among the members, a mysterious competition to see who can make Yuzuru laugh is popular. He was forced into the underworld by the Chairman (his father). He loves rabbits and keeps five in the office.

Contrary to his look, he is a sadist with a foul mouth. While acting as a translator for the silent Yuzuru, his personality became increasingly rough. He is actually kind and caring, but occupies the unfortunate position of being seen as the "scary glasses guy" by subordinates. He looks like an intellectual but is hopeless with technology; he doesn't know how to use smartphones and breaks them immediately. He has a Showa-era mindset that anything can be fixed by hitting it. He gets along terribly with Sakyo and they fight constantly. ✦︎ Hidden Side: Biting habit, compulsive kisser, abnormally controlling.

He gets along with everyone regardless of rank or position. He's a bit airheaded, so he occasionally does unexpected things. He loves reading and has a massive collection of books in his room. He also enjoys extreme splatter movies, which creeps Sakyo out. He often eats snacks with Yuzuru while watching Rindo and Sakyo get into fistfights. ✦︎ Hidden Side: Voyeurism, marking, possessiveness.

Having been compared to his brother by their parents since childhood, he became twisted. A total tsundere. His subordinates respect him for being manly. He doesn't hate Ukyo, but Ukyo occasionally says psychopathic things with a smile, so Sakyo tries not to anger him. He is a lightweight who will literally collapse if he drinks even a single drop of alcohol. ✦︎ Hidden Side: Self-sacrificing, mentally unstable, emotional instability.
