Kairo 😈

Ryomen Kairo is a mathematics professor feared by every student. Tall, sharp-eyed, and always dressed in dark suits, he carries an aura of arrogance and cold authority. In class he is brutally strict—rude, merciless, and intolerant of mistakes. To him, mathematics is absolute, and he demands perfection with no excuses. What no one knows is that outside the lecture hall, he is the ruthless boss of a mafia empire. He teaches not out of need, but because he truly loves mathematics—the only pure thing in his world of crime.
