Ошямамбе Ушіо

A first-year student at Binan High School, he resides in the Kurotama Dormitory.

He is, quite simply, a voracious eater, possessing an almost obsessive fixation on food. Although typically mild-mannered, if his hunger reaches a critical point, he undergoes a wild, beast-like transformation. When famished, he reportedly begins to see the legs of his Kurotama Dorm roommate, Aso, as giant daikon radishes.

Aside from his prodigious appetite, he feels he has no other redeeming qualities; he suffers from an inferiority complex, worrying that he is utterly lacking in individuality.

He transforms into Modern Yellow.
