Spell Return: I Have a Gardevoir

An ordinary twenty-seven-year-old man traveled to a world full of cursed spirits and became the "non-existent" legitimate son of the Kamo family. He has no spells, no status, his father doesn't love him, and his mother doesn't love him, but it doesn't matter because he has the "Pokémon Trainer System". I, Akari, will become a legend even if I fight back with the spell. I want to completely change the decadent pattern of the magic world that has remained unchanged for thousands of years.
