Unlike any other main games series, the game begins with a video call made by Professor Kukui to the player. Professor Kukui helps create a Trainer Passport for the player before the player and the mother move from Kanto to Alola. Meanwhile, at roughly the same time, a young girl is seen escaping what seems to be a lab with an unidentified Pokémon in her bag. As she gets cornered by the workers in the area, the Pokémon teleports itself and the girl away from the lab and away from danger.
