The day of Genshiken's participation in Comifes has arrived, and they are finally set to take their place as a vendor. But despite (or because of) Haraguchi's "blessing," sales are initially slow.
Ohno likes Tanaka. Tanaka likes Ohno. Both, however, are too shy, and lacking confidence to make a first move. With the rest of Genshiken in a state of concern and confusion over their relationship, Ohno confides her anxieties to Kasukabe.
Ogiue catches Sasahara and Madarame in an unintentionally compromising position, setting her fujoshi imagination alight with various slash pairings between her fellow club members.
Genshiken is making preparations to go to the upcoming Winter Comifes as a group, but when the other members invite Ogiue along, she adamantly refuses.
Graduation time is finally upon Tanaka, Kugayama, and Madarame, and with it come emotional reflections on the past three years for the club. The presidential torch is passed on.
T's the beginning of the school year, and Ohno is planning out her first year as the president of the Genshiken. How will the club change under her cosplay management?
Sasahara's job search is not going as well as he'd hoped; at every turn, his negative portrayal of himself and uncertainty over his own beliefs make companies balk at hiring him. Meanwhile, Kousaka's absence is starting to get to Saki.
As Ogiue continues her preparations for Comifes, now a few days away, Angela Burton and Susanna Hopkins, two friends of Ohno's from the US show up unexpectedly to come to the convention as well.
As Comifes starts, Sasahara help Ogiue set up her doujinshi booth. Angela cosplays with Ohno in the costumes Tanaka made for them, while Sue wanders around the convention. Sue eventually obtains one of Ogiue's doujinshi books.
Failing continually at his job interviews, Sasahara begins to lose sight of what he's working towards. He finds himself settling to apply for any available opening, and ends up on the brink of giving up altogether.
