S1·E4 Christmas in the Holy Land

With Christmas around the corner, Nanashima suggests everyone have a party. However, Kae says she can't possibly make it because she's going to Comiket. In the end, everyone decides to go to Comiket together, then have a Christmas party afterwards. The boys are bewildered at their first visit to Comiket, and feel as though everyone is looking at them askance. Meanwhile, Kae is busy bustling about the entire venue, until she runs into some trouble at the cosplay plaza. And then, a handsome cosplayer saves her.
