Chako and her friends can't wait for the Cosplay World Series! Their East Oizuki Academy team has earned quite a reputation in Japan, and she knows that they can also win the world championship. Only one thing stands in their way--a lack of interest. The team doesn't have an adult sponsor, and can't keep up enrollment. As a result, they must fight rivals, find new members who want more than just to see the girls disrobe, and learn to change costumes in a flash.
