Kugayama is an overweight guy who stutters a lot and is the only male artist of the Genshiken who help with club doujinshi along with Ogiue.
He loves to draw but he doesn't take it too seriously because most of his drawings are sketches; however, he is very serious when he draws explicit scenes of his favorite characters. When he worked on the club doujinshi, he became frustrated with Sasahara and barely made the deadlines to get it done. He finds a job in sales at a medical device manufacturing company.
He is a very shy man who stutters when he talks. He lacks motivation and has commitment issues, which is seen when the club doujinshi was being made. The only time he has motivation is when he draws erotic pictures. He can keep secrets and doesn't gossip about any he knows; this is seen in the series when he doesn't tell the club members about Ohno and Tanaka's relationship when it was a secret.
