A Hunter For Fun (Rwby x male one punch man reader)

This is a story i've been wanting to do for a while, this is also my first story so if anything is wrong please tell me.

Your name is (Y/N) (L/N), you where once a normal human, but one day that changed when you saw a kid about to get attacked by a bunch of grim and stepped in to save him, the fight wasn't easy but you won, barely, and on that day you decided to train tell you where the strongest human on remnant, and kill all grim, in one.punch.

I do not own one punch man nor RWBY
you own yourself
I only own the story
