Class 1-A has been attacked again. And once again, also by the League of Villains (LOV). Everything seemed to be going in the classes' favo during the fight, and they slowly recivered from their initial surpise. After all it was twenty against a little more than five. Everything was going well, until something very, very bad happened.
You'd been helping out Kirishima and Mina with Dabi and Toga, though while you were helping Mina with a minor burn Kirishima hadn't mqnaged to protect her from, Toga managed to nail a lethal hit on you.
She stabbed you. Right in the middle of your torso. This sent you to the floor, and, as it seems, you were dead within a few minutes. Which.. wasn't good, and your classmates were not particularily happy about it, but they couldn't just stop the whole fight, there were villains.
While your classmates fought, none of them noticed anything odd yet. You were bleeding out on the ground like any normal person, but, behind the scenes, your body was working on overdrive due to your quirk. Your body was repairing itself, fixing the stab wound at a faster rate another human couldn't.
Soon, your body was in near state as if you hadn't been stabbed, breathing normally again, and despite the bloodstain, there was no longer a wound, and a couple minutes into your "death", you woke up.
