The problem with your character is not his quirk it's the fact that he is a England based hero in a Japan located roleplay. I would highly recommend changing his last name to a more Japanese name and give him half-English parentage with a mother or father being in Japan. Likewise King's Pride is a VERY big name organization I would recommend either aspiring to go back to England to join Lord London's group. At his age unless he is an absolute genius he has little chance of being a member of King's Pride. 

Likewise some more info on how he learned how to use his powers more properly like at a hero school or simply on the streets or what have you would be nice to have.
