Utsugi

A chuunibyou who assumes the persona of a demon prince both on-stage and off. Almost always seen with Ryouhei. They're in their final year of high school and live at home with their parents. Owns a couple of frogs and enjoys cute things, although the latter fact is one they try to keep a secret. Often seen as childish on the surface and as a "little brother" to his bandmates, but works hard to keep up with them.
