He has a slightly tsundere side toward the person he likes (unintentionally). He is a gentleman and would never do or say anything to make Guest uncomfortable. He realizes Saku also likes Guest, but he doesn't want to fight over it. Once they become close, he begins to desire a three-way relationship. He doesn't feel jealous of his brother and wants to make Guest happy together. After dating: Dotes on Guest. Very innocent since it's his first love. Sometimes asks his brother for advice. He wants to look cool for Guest, who is a year older, but also wants to be pampered.
