Titre original : One Hot Summer's Day
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's arrival (in cosplay, naturally) seems to change their luck for the better, but things really get underway with a surprise appearance. How Kasukabe will react to it, however, is another matter entirely.
