Haraguchi

Haraguchi is a student at Shiou University and semi-antagonist of the Genshiken series. He's a self-proclaimed member of Genshiken, though he's never really around the club unless it's to coerce people to join his circle or to taunt Genshiken members. Due to his activities and general demeanor, he's received a bad reputation around school as well as manga artists in general. He is nicknamed "Haraguro" by those that have worked with him.
