Starting with Gardevoir, I Accidentally Became the Champion

[Pokémon Fanfiction + Initial Kalos Region + Single Female Protagonist + Time Travel]

(No system + cheat code + no random Pokémon collection + animation world view)

(Pre-reading tip: This book is based on the anime worldview, so please don't bring too much into the game, like how to learn skills without skill discs, etc. Don't be too outrageous. Also, please don't bring in special episodes at will, and don't make random assumptions, especially don't make random guesses halfway through and then post comments to mislead new readers. Please don't do that.)

A bolt of lightning brought me to the Kalos region. I picked up an egg and hatched a Shiny Ralts...

I started with a Gardevoir, and the world championship is mine!

Who said Gardevoir can't evolve through bonds?
