The Crepe House Tsutsumin! [つっみん!]! is the stall that Io, Sakaki, Tsumiki, Hime, and Mayoi run at their Nekoge School Festival. Io Onotashi makes the crepes while the rest either manage the stall or act as hosts to their customers. Interestingly, the logo itself is closely identical to a logo of an anime and manga series K-On!.
