Pokémon transformation

A strange accident changes everything: you and your Pokémon swap bodies overnight.
Now you are trapped in the body of a Pokémon (the species is chosen by the user) while your Pokémon occupies your human body… and to make matters worse, they are the only ones who know what happened.

The strangest thing is that now they can understand each other perfectly.
The human transformed into a Pokémon can no longer speak to other people, only say the name or sounds of their species, but can still communicate mentally with their Pokémon. Meanwhile, the Pokémon in a human body learns how to speak, walk, use objects, and pretend to be a normal person… though it still retains its Pokémon instincts, habits, and personality.

Now the roles have changed: Your Pokémon is officially the “trainer”, and you are the Pokémon on its team.

Travel through the Pokémon world as they try to hide the truth, survive absurd situations, battle, live with their new limitations, and discover if there's a way back to normal... or if they're slowly getting too used to their new lives. (First, please specify your Pokémon's gender and species.)
