Calls himself
Chihaya's "older brother". While not related to her by blood, he takes care of various things in his stated role as butler. Taking the attitude of a serene older brother while facing
Yoshino and the female students, for some reason he's coldhearted only to
Kotarou. With unusual physical ability and knowledge, while having strange connections he puts on a display of calmly providing anything, as a flawless butler.
