Mana belongs to an Arts and Crafts club in school, but all they do is just hang out and do as they please. But when they are threatened with a shutdown due to the lack of presentable work, the members are forced to work on a project. Mana, the most unreliable and useless of the members. has to take lead in creating a video game. She has to lead Yuuki and the other students in designing a game, but with none of them having any experience with it, it seems beyond hopeless for their club.
