Synopsis
Shunta Mogami has a passion for the Battle Spirits card game. One day, a radiant light from a Battle Spirits card transports him to Spirits World, the realm where all Battle Spirits originate. There he meets a girl named Eto, who explains that she summoned him to prevent the destruction of Spirits World by the revived Evil God-King—a being that once plotted the realm's annihilation before being defeated and sealed away. Now, together with Yoku Albatrosa, a confident green-deck user who also comes from another world, Shunta sets out to find the twelve God-Kings whose power originally sealed the Evil God-King.
