While on their way to a battle in the Kalos region, Satoshi, Pikachu, and their friends discover a strange portal in time. Suddenly, Pikachu gets sucked into the portal, and Satoshi jumps in to save his best friend. They both later find out they have been sent to another dimension, and knock on the door of a nearby house, which we soon find out is the residence of Nobita Nobi and his best friend Doraemon.
