I Just Became Champion, and Now You Want Me to Promote Pokemon?

(Some changes have been made, such as removing the level 100 cap and making levels unlimited, and cutting Dynamax, Terastallization, and Z-Moves. Please be understanding, and feel free to switch off your brain while you're at it.)

An orphan who has been frail and sickly since childhood, Bai Yu makes a wish upon a shooting star to be reborn, only to unexpectedly transmigrate to the world of Pokemon!

There, she meets one companion after another and slowly rediscovers what it means to live, until she reaches the pinnacle of the world. At last, she wins the ultimate showdown against Ash and becomes the world champion, recognized by everyone!

Just as the whole crowd is cheering for her, everything in Bai Yu's vision suddenly begins to shatter. In a panic, she finds herself back in the basement on Blue Star.

Bai Yu thinks it was all just a dream, but her companions are still there, her body has become healthy, and Pokemon have appeared in this world!

The problem is, humans have completely forgotten everything they knew about Pokemon. Most absurd of all, they mistake them for terrifying monsters and launch a campaign to wipe them out!

"Are they trying to get themselves killed? If they provoke the alpaca, I can trade my life for it, but can you?"

And so, burdened with the great mission of saving the world, Bai Yu sets out to teach people about Pokemon.
