Oc or reader is a female. Pokemon exists but they can't interact with people and people can't interact with them. Unless oc catches and then releases them from her pokeballs. Pokemon that she catches she can't get rid of (not that she would anyway) Her quirk let's her catch Pokemon and store them in a pocket dimension where they live on a ranch like proffesers oaks. Her Pokemon can't die they only faint and once they are returned to their pokeballs they are healed.

They eat human food. She can understand them. When they talk it'd like they are speaking English. But other people just hear them say their names.

She Dosent name them. As when she catches them a voice in her mind tells her all about them (like the powder when you catch a new Pokemon)  she never has two of the same Pokemon.

But she can have all the different eeveeulations. And if a Pokemon Dosent want to evolve they don't have to. They still get their evolved moves and they still get stronger they just stay in their first evulation

She is bisexual and all of class 1a have a crush on her.  She is really good friends with all class 1a.
