One day at school, the Amusement Club pick up an odd game cartridge and suddenly find themselves transported to the world of Pokémon! They're trying their best to get home with the help of their newfound Pokémon, but will their adventure be as laid-back as their official story? Can they survive in this new world? Can Akari manage to catch her first Pokémon!?
