The mythical beast disappears and the city remains as usual. Three hundred years ago, after the destruction of the Pokémon world, the Pokémon came in the form of cards. The main card can accompany you on a daily basis, but the secondary card is asleep due to damage to its origin. Only fusion can briefly awaken it.

When various forces are secretly surging for the legendary card, his peaceful daily life is being quietly disturbed.
