Lala's personal bodyguard and the strongest swordsman on the planet Deviluke. He ended up as Assistant Chief to Rito's father, who works as a manga writer—a position he landed after an incident involving Lala went sideways. Despite being an elite fighter, he's notorious for having almost no sense of direction, which means he's basically always lost. It's become one of the series' running jokes.
By the time "To Love Ru, Darkness" rolls around, he's switched careers and become a mangaka himself.
