Mitsuru's former kouhai, Igarashi Miya, shows up at the dorm, on the run from a bunch of girl gang members. Though she presents a tough exterior, Miya is in trouble, and she knows it. When Igarashi gets called out, Kazuya and the others have to work fast to help her. Mitsuru also catches a nasty cold, and Shinobu's psychotic sister makes another appearance.
