Імамура Кохей

A first-year Mechanical Engineering student at Izu University. He is Iori's best friend and a diehard otaku, perceived to be a lolicon by his acquaintances. He happens to be particularly obsessed with the little sister character trope (hence his obsession with Shiori Kitahara). While many are repulsed by his otaku lifestyle, he is indifferent to how he is perceived by others.
