Comic party - Sekihiko Inui

The Comi Rangers find the bomb and manage to disarm it, but Kingu Jacky is still bent on destroying the party. He and Subaru battle it out, and Subaru finally manages to defeat him. Kazuki has problems with the story for his next doujinshi, so Mizuki convinces him to go out and enjoy the summer with her. In exchange for doing what she wanted, she agrees to do one thing Kazuki wants. He asks her to be his poster girl to help him sell doujinshi, which seemed pretty bad by itself, but then Taishi tells her that part of being a poster girl is cosplay (costume play). Taishi enlists the help of Reiko Haga to convince Mizuki that cosplay isn't all bad. Reiko succeeds and Mizuki starts work on her Card Master Peach Costume. Kazuki, realizing how hard Mizuki is working for him, decides that he must finish his doujinshi in time. He ends up overworking himself and getting sick, so Reiko, who happened to come over to return a video game, calls her friends to help him finish. With everyone working together, Kazuki's doujinshi is finished. Mizuki finished her costume (she even bought the transformation stick), and with her as a poster girl, Kazuki manages to sell out all his doujinshi.
