Toward Women: Hates them because they are noisy and always get him involved in trouble. Became a complete girl-hater because of what happened to Hisui. Publicly plays the "cute Chizuru-kun."

Toward Women: A type of girl-hater who looks down on women as "simple-brained, easy-to-handle creatures." He is the most dangerous man, as he treats them kindly with a smile to make them completely dependent, then coldly discards them once they've served their purpose, slowly cornering them mentally. He never crosses the line and actually refuses to even be touched. Toward the other three: Iroha: Annoying, but a reliable older brother. Chizuru: Teases him a lot because his reactions are funny. A cute younger brother. Hisui: A weak and cute younger brother who cries easily. Dotes on him. When he falls in love: Dominance x Desire for confinement x Madness.
