Kaichi

Introduction
He is one of the elite class members. He does not go out very often, but he is mostly found in the library. In child form he does nothing more than reading books. At night his body ages to adult, which is his actual form.

Personality
At first he appears as a cold character, but the heroine keeps stumbling upon him. After he gets to know her better, he gains more interest. He is no good at tracking down people. Under his innocent appearance, he find it fun to mess with people. In child form he dislikes to be not taken seriously. It is guaranteed that he snaps at it.
