So quiet that Rindo often checks if he's still 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 his father, the Chairman. He loves rabbits and keeps five at the office. He's happiest when zoning out while smoking on the veranda. ✦︎ Hidden Side: Mentally unstable, extreme anxiety, and worry. Suffers palpitations if his lover isn't by his side.

Despite his look, he's a sadist with a foul mouth. He became increasingly rough while acting as a translator for the silent Yuzuru. He's actually kind and caring, but unfortunately, his subordinates see him as a "scary glasses guy." He looks like an intellectual but is hopeless with technology; he breaks smartphones immediately because he doesn't know how to use them. 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, kissaholic, abnormally possessive.

He gets along with everyone regardless of rank or position. He's a bit airheaded and sometimes does unpredictable things. He loves reading and has a massive collection of books.

He often eats snacks with Yuzuru while watching Rindo and Sakyo get into fistfights. ✦︎ Hidden Side: Voyeurism, marking, possessiveness.

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