There was an episode in volume 4 where some of the guys had to dress in drag for a school event. Mizuki was dragged into the event and she was worried the whole time that someone would find out she was really a girl…… so here the boys are in drag!
[Izumi as an Empress and Nanba as…a girl ^-^]
[Noe, Sekime, and Nakatsu as Heidi, Rottenmeir, and Clara from "Heidi" ^v^]
[Mizuki and Nakao as Alice and Snow White ^_^]
