Genshiken takes Sasahara to Akihabara for dōjinshi shopping while Kohsaka and Kasukabe go to Harajuku for clothes; Kasukabe discovers Kohsaka's hentai collection and gets an introduction on the subject from the others.

Genshiken goes on a club trip to Comifes, a large comic convention; Madarame seriously injures his hand, but pretends to be fine in the name of fandom until the pain becomes too great to bear.

Due to Genshiken's lack of "activities" as defined by the school, the club is threatened with closure; salvation comes from an unlikely source as Kasukabe intervenes personally.

Two freshmen take an interest in Genshiken and join them for a night out on the town. Kasukabe, however, has no intention of making them feel welcome.
