碧蓝之海 第三季

主角

Kouhei Imamura

今村耕平

声优: 木村良平

A first-year Mechanical Engineering student at Izu University. He is [Iori](https://anilist.co/character/123182/Kitahara-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](https://anilist.co/character/125928/Kitahara-Shiori)). While many are repulsed by his otaku lifestyle, he is indifferent to how he is perceived by others.
