Shunta Mogami loves the Battle Spirits game. One day he is transported by a light from a Battle Spirits card to Spirits World, the origin of all Battle Spirits. He meets a girl named Eto, who claims to have summoned him to Spirits World in order to prevent its destruction at the hands of the revived Evil God King, who once plotted the destruction of Spirits World before being defeated and sealed away. Together with the confident, green-deck-wielding Yoku Albatrosa, who also came from another world, Shunta sets out to find the twelve God Kings whose power originally sealed the Evil God King. <br><br> (Source: Anime News Network)
