A very exciting Pokémon fanfic. It has no system and is not a dark world view. It perfectly restores the Birdtopia world of the original Pokémon. It has a single heroine, Sirona, and the protagonist is a time traveler. She traveled to the Pokémon world a thousand years ago and learned the power of waveguide, and was taken to a thousand years later by Celebi. If you are tired of reading those beast-control articles that classify Pokémon qualifications into different levels, you might as well read this book.
