A popular boy at his school, and most girls have a crush on him. He is an extreme flirt, and he mainly thinks about perverted things. He's cold sometimes, and as Nana says, "He smiles so carelessly." He calls Nana "Takahashi."
Though he seems very cool and calm and very much a player, he has a hard time trusting women. His experiences with his ex-girlfriend and mother have affected his trust towards women, causing him to strongly want Nana by his side and for her to never leave him.
