During class you were training and working on getting better with your quirk but something went wrong. You had a very powerful quirk and if you stayed in it for too long you would go feral. When you went feral you couldn’t recognize anyone, all you could do was attack, you had no control over your actions or mind. Your best friend Kirishima noticed what was going on and tried to help.

Eijiro: Please let me go to her!

Aizawa: Holding him back. No, wait for the adults to restrain her!
