Pokémon Trainer Satoshi has a new plan: see the world! But first, he and his partner Pikachu are headed to the opening of the Cerise Laboratory, a research facility dedicated to uncovering the mysteries of Pokémon in every region. Ash meets Gou, another boy with boundless curiosity about Pokémon, and both are overjoyed when Professor Sakuragi asks them to become official research fellows. With Ash as determined as ever to become a Pokémon Master, and Gou aiming to catch one of every Pokémon (including the Mythical Mew), our heroes are in for adventure and excitement as they explore the wide world of Pokémon!
