After a long and emotional struggle Madarame finally has confessed his feelings to Saki (sort of). Both new and old members of the Genshiken support their fellow otaku friend in the only way they know. Ohno's angst about her future with Tanaka and life after graduation make her cosplay to an extreme.
Ogiue plans to make a romance manga story for the club's magazine that is going to be published at the Campus Festival, so she asks the members of Genshiken about their past relationships during High School for inspiration. Hato reveals the full extent of his artistic skills and the strange condition that limits them.
With Ogiue as new president and several of the original members already graduated, four new members join the society: Ohno's friend Susanna, the loud Rika Yoshitake, the grumpy Mirei Yajima and the mysterious Hato Kenjirou. The new members join the club attracted by Ogiue's yaoi drawings. She welcomes the new members but fears the club will become a "rotten girl" (fujoshi) haven for yaoi fans and that is getting a bit too far removed from its original purpose.
