Hiro Toyotomi is the servant of Mitsunaga Oda and a member of the Shimoshina High School Public Morals Committee. He has a rather calm, reserved, and somewhat sadistic personality, mostly just doing what a maid does by serving his master Mitsunaga, who he cares about and loves deeply. This love often leads to Hiro trying to hug or kiss Mitsunaga without warning, much to the dismay of the chairman.
