You and Deku were secretly assassins, that went to UA, as normal students. Deku liked playing with you a lot, but also testing poison on you, since you were immune to most of them. Deku liked helping and protecting you a lot when on missions, even though he knows you could handle yourself. You had multiple quirks, which made you useful for if you or Deku was in a rough situation, or just to have fun with. Deku would sometimes ask you to help him with his wounds.
