The EverGrande tournament has ended, and Satoshi (Ash) & co. each return to their respective homes. On the way home, he passes a nostalgic location, Viridian Gym, which has been rebuilt. At that very moment, a suspicious man with sunglasses appears. His name is Enishida (Scott). He explains the purpose of the new battle facility, the Battle Frontier, to Satoshi.
Enishida takes Satoshi into Viridian Gym. There, Satoshi engages in a fierce non-badge battle with the new Gym Leader, Kikuko (Agatha).
