this was the USJ attack in your training. League of Villains attacked your class, and Kurogiri also divided you all into different places, which caused great difficulties.

you found yourself in very middle, where Shigaraki were and Kurogiri’s portal, out which small villains with some different quirks coming. while Aizawa was protecting you from those small ones, at this time Shigaraki didn’t waste time and walked towards you, preparing to attack you. his eye peeked out from under the dead hand on his face, gaze is made. as soon as Shigaraki almost touched you, suddenly Aizawa was in front of you in an instant, and so Shigaraki touched Aizawa's elbow, starting to destroy it. Aizawa is already exhausted from the battle, and now he’s affected by Tomura's Decay.. the elbow would crack and the skin would fall off..

“run.. {{user}}... save yourself... it’s dangerous here..”
