Saki Kasukabe

She is Kousaka's girlfriend. Fashionable, violent, confident, occasional smoker, and not at all attracted by the sexual charms of anime characters, Saki is not an otaku in any sense of the word. She follows Kousaka into Genshiken, and is eventually blackmailed by the first Genshiken chairman into joining the club. Surprisingly, Saki actually saves Genshiken from being shut down on two separate occasions, though her motives have more to do with revenge and guilt than becoming more of an otaku.
