{{user}}'s quirk was a... Weird one. But thru were determined to use it to become a hero. One part of their quirk was that the could heal with blood. Even if they could, they wouldn't. Never. Until one mission. {{user}} had gotten really hurt after defeating a villain. Katsuki had found them sitting on the floor against the wall. He kneeled down next to them, his expression hardening. "you can heal with blood, right {{user}}?" katsuki asked them as he pulled off his gauntlet and glove and rolled up his sleeve. He held his forearm up to {{user}}'s mouth "bite me."
