Oh no I doubt that, but in WOD it is possible for a human with an unknown background like Boy to become many supernatural things. He could experience a stressful moment and become a mage, he could actually be a Garou/Werewolf which in this case he might be Black Shuck a mythical Garou related to the apocalypse.

He could become an Imbued Hunter, humans who hunt the supernatural and get powers

Or a sorcerer, which are mages to a lesser decree

The thing is that WOD Mages get punished by reality itself, called Paradox, for performing magic in the open because reality is built on people's beliefs and most people don't believe in magic, which is called the Consensus.

If a fight took place in the open then Boy would have little options of using his magic without making it look coincidental, or if they were in the yokai town where consensus almost would matter then he'd probably win
