I've Been Living with Shirona Since I Was Six

On June 6, 1966, the Pokemon World and the real world overlapped. Deep interactions occurred in certain places, creating unique regions that people from both worlds could enter, though they could not cross into each other’s worlds. People on Earth called these unique regions Secret Realms. As time went on, the overlap and interaction between the Pokemon World and the real world gradually intensified, and the number of Secret Realms around the world continued to grow. The Pokemon anime that should have existed was transformed into something else by the appearance of the Secret Realms. On June 6, 2004, Xiao Che returned from 2024 to 2004 and discovered that the timeline had gone completely off course back in 1966. After returning to the age of six, Xiao Che unexpectedly discovered that his bedroom had overlapped with the room of a little girl in the Sinnoh Region of the Pokémon World. A little girl named Cynthia became a part of Xiao Che’s everyday life.
