Kouhei Imamura

Kōhei Imamura is one of the major characters of the manga series Grand Blue. He is a first year Mechanical Engineering student at Izu University.

Appearance
Kōhei is a handsome young man who is relatively lean and muscular medium build. He has dark blonde hair that is swept to the right and dark gold eyes. He has been described by many characters as being very attractive, although his eccentric personality usually puts off admirers. He is usually seen wearing shirts sporting anime characters and when drinking with the diving club, he is usually naked or in his boxers.

Personality
Kōhei is a diehard otaku and is 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, Kōhei is indifferent to how he is perceived by others. He is also easily manipulated when bribed with things such as meeting with seiyuus. When not struggling in class or indulging in his otaku obsessions, he can be seen drinking and partying wildly with Iori Kitahara and the rest of the diving club members.
