As the Gyarakushi Kappu (Galaxy Cup) begins in Mutsuba-cho (Mutsuba Town), Yuamu accidentally activates the rock-system that turn people into cards and get possessed by something in the lab. Meanwhile, Yuudiasu (Yudias) and Yuhi pick up Epokku (Epoch), since Yuudiasu promised Arufureddo (Alfred), Epokku's butler, that he'd be her tutor in rush duels. They take her to Mutsuba-cho to show introduce her to the card game and end up meeting Yuamu, who's acting weird.
