第 3 集: Genshiken 攤位銷售慘淡，直到 Ohno 與一位驚喜來賓抵達 Comifes。
2007年10月24日 播出
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. (Source: Wikipedia)
