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. 
BattleMomo Yaoyarozu, Kyoka Jiro and Denki Kaminari are transported to the Mountain Zone with several villains. Momo creates weapons for herself an Jiro to defend themselves while Denki runs scared. He begs for a weapon, but Kyoka tells him to use a Quirk to create an escape route. Denki explains he can surround his body in electricity but if he releases it, it will spread out across the area and risk hitting the girls.
A villain takes a swipe at Denki, but he ducks and gets kicked into the villain by Jiro to electrocute them. A second villain tries to use his elastic Quirk to strike Denki with a stone covered arm. Kyoka counters with her Earphone Jack Quirk, by blasting the stone a part with sound waves. Another villain tries to jump in and Momo uses her Creation Quirk to create a capture net. Both villains fall into Denki and are electrocuted.Kyoka uses her amplified sound waves on the surrounding villains, complaining that Denki needs aiming gear for his costume. She nearly suffers from an enemy sneak attack, but Momo repells the criminal. Then Momo creates a one-hundred millimeter thick insulation sheet to protect her and Kyoka, allowing Denki to use his Quirk at it's full power. He sends his electricity shooting out, shocking all the villains at once.
AftermathKyoka notices Momo's shirt is destroyed by the blast, but Momo says she can easily create a new one. As Denki walks towards them, Kyoka covers Momo and tells him not to look. He walks past after short circuiting his brain from his own attack.
A villain hiding underground suddenly appears and takes Denki hostage. The villain reveals that his own electric type Quirk allowed him to resist Denki's attack. He threatens to kill Denki, but the student is saved by Snipe when Tenya returns to the U.S.J. with reinforcements.
