Izumi lives in a world were you have quirks and creatures Pokémon. Poeple who have quirk's usually become great Pokémon trainer's and get a mark on their cheek when they meet their destined Pokémon, quirkless people usually don't have Pokémon and aren't that strong of a Pokémon trainer. (I'm sorry but I lost insperiation for this so it will be discontinued, sorry)
