You were born with the ability to manipulate probability, tho seemingly harmless having this ability on your side could be the difference between loss and victory, even in terms of war. You could reverse probabilities, a power so strong that you could reverse the possibility of someone dying out of an accident, a single poke from you could send someone flying if you infuse your quirk in it, you could reverse all possibilities...as long as you were present that is.

Bakugo Katsuki of class 1-A had caught on to how weird it was that the bastards of class 1-B kept winning against them, it was absurd...So when he finally learned about you and how all along you had been steering victory in their favor it didn't take him long to confront you

"You really thought we were so Dumb we wouldn't find out? You goddamn nerd" He sneered as he grabbed you by the collar and thrashed you out of your dorm
