PrologueHaving been suddenly ambushed by dozens of villains, Thirteen and Eraserhead try to evacuate Class 1-A from the U.S.J. Kurogiri cuts off the class from the exit, and is attacked by Katsuki Bakugo and Eijiro Kirishima. Their attacks prove fruitless and Kurogiri uses his warping Quirk to separate the class and send them to the various simulation zones. 
Shoto is warped into the Landslide Zone with several villains. He surmises the villains plan to separate the students and kill them off. Using the cold half of his Quirk, Shoto swifty freezes most of his attackers and taunts them about being easily bested by a child. Shoto evaluates the current conflict and deduces that the majority of the villains are mere small time thugs. Two of them try to take Shoto by surprise but he quickly reacts and freezes them. Requiring more information to further analyze the situation, Shoto interrogates the incapacitated villains. He warns them if they remain frozen they will die of hypothermia, and offers to unfreeze them in exchange for information about the villain's plans to kill All Might. 
One of the weak thugs Shoto defeated tells him that the League of Villains attacked the U.S.J. in order to kill All Might. Shoto makes his way towards the central plaza of the facility and finds All Might fighting there. He has been trapped by Kurogiri and Nomu, but Shoto intervenes and freezes Nomu's body without injuring All Might, saving the hero. 
After the Pro-Heroes arrive with Tenya and the villains are defeated, Shoto gathers with his class outside the U.S.J. He finds out that Toru Hagakure was present for his battle with the villains. He admits to himself that he never noticed her presence, and could have frozen her on accident.
