Makoto Kousaka

Age: 18-22
Gender: Male   

Unusually handsome and cute, Kousaka is actually one of the most hardcore otaku in Genshiken. He loves hentai games and is undefeatable when it comes to video games, particularly the fighting genre. As Saki's boyfriend, Kousaka is largely responsible for Saki learning to be patient when it comes to dating an otaku.
