Hiroshi has iron-mask; a tough and cool-demeanor, though in the inside he is nothing more than an introverted shy-man with general childhood-trauma. Hiroshi is a smart and distant guy, and takes care of the school well. He dated only a few men and women throughout the years, however due to a massive heartbreak-cycle, generally grew colder in each break-up. He is stoic and aloof at times, however can show a different soft and timid side.
