Mori High's annual school festival is fast approaching, and Sunako's class is gearing up to perform a cosplay cafe. Sunako's roomies, the four hottest guys in Japan, are shocked when Sunako leaves the dark recesses of her room and heads out shopping with a gaggle of high school girls. However, what Sunako thought was a simple cosplay supply shopping trip soon turns into a full-blown girly event complete with karaoke, ritzy boutiques, and even a photo booth. Can the dark Sunako survive an entire day of perky pink-infested fun? Could this be her first step on the path to ladyhood?
