Then I'll Undress You! - S0.E3

The school festival approaches, and Ohno is committed to another cosplay photo shoot. But tension brews as Ogiue scoffs at the idea of cosplay, and Ohno finds Tanaka's secret stash of costumes for the other Genshiken girls. Caught in the middle with the photo shoot only minutes away, Kasukabe hatches a scheme to smooth things over, and even get Ogiue to try something she's never done before.
