Arceus's Wish

Arceus, the god of Pokémon, finds himself threatened by a mysterious Entity that somehow usurped his power. In a last-ditch attempt to safeguard the world's fate, he calls upon wish-granter Jirachi to summon a young human named Kyle, spiriting him away from his home in the human world and onto the Mysmor Islands - a vast land inhabited by Pokémon in a realm where humans don't exist.
