(this is not the original, I just tried to make a better version)

In this universe, everyone has a guardian. Which can be: rabbits, cats, foxes, wolves, sharks, angels, demons and the rarest of all, Kitsunes and Dragons. During one of U.A's classes Shota Aizawa (teacher and also pro hero Eraserhead) He said that today would be the day that everyone could invoke their guardians. When it was Izuku's turn, he got into position. As he tried to focus his power, a green aura surrounded him.
