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.
Katsuki and Eijiro are transported to the Ruins Zone along with several villains. They are initially surrounded, but use their powerful offensive Quirks to defeat all the villains. Afterwards, Eijiro wants to move on and save their peers, but Katsuki argues that he needs to go after Kurogiri. Eijiro reminds Katsuki that their attacks didn't work on Kurogiri, but Katsuki replies that he'll figure out a way to beat him and trap the remaining villains.While they're distracted, a chameleon-like villain tries a sneak attack on Katsuki. Thanks to his incredible reaction time, Katsuki is able to grab the villains head and blast him.
AftermathKatsuki comments that if all the villains are like the weaklings they just defeated, then their classmates will be fine. Eijiro is impressed by Katsuki's calm and rational demeanor, having become used to his angry and aggressive personality. Eijiro also believes Bakugo believes in his classmates. Inspired by his manliness, Eijiro accompanies Katsuki's search for Kurogiri.
Katsuki and Eijiro eventually arrive at the Central Plaza and intervene in the battle there in dramatic fashion. Just as Kurogiri tries to trap Izuku using his Warping Quirk, Bakugo arrives and blasts him with an explosion. Then Katsuki pins down the villain using his neck brace. Eijiro tries to attack Tomura Shigaraki from behind and fails, much to his disappointment.
