He is a substitute English teacher at the Karasumori High School. He is one of the few humans in Karasumori that also has a hidden power.

Mino has brown hair that extends past his neck in the back with two looped pieces at each side of his face that are shorter in the front. He frequently wears a teacher's uniform: brown shoes, tan jacket with matching pants, red tie, and white dress shirt.
