Toshikazu Hazamada

A teenage male Hazamada is initially tall but later in the story like Tamami he shrinks to Koichis height. In the anime he is simply depicted as already being short in stature. He has long straight dark hair and wears a school uniform with the character along the collar and several belts spread vertically down the chest mirroring a strait jacket. He has dark color upper eyelids. Source: JoJos Bizarre Encyclopedia
