Shota Aizawa & U.A. Students vs. Tomura Shigaraki & Nomu

Shota Aizawa & U.A. Students vs. Tomura Shigaraki & Nomu is a battle fought between the Pro Hero Eraserhead and Class 1-A students Izuku Midoriya, Tsuyu Asui and Minoru Mineta against the Villains Tomura Shigaraki and Nomu during the U.S.J. Incident.

Prologue
Shota quickly takes down villain after villain using his Erasure quirk combined with his close-quarters fighting. Tomura observes the battle from a distance for a while before deciding to enter the fray himself.

Battle
Tomura rushes at Shota while counting out loud the decreasing maximum time that Shota can keep his quirk active. He grabs the end of Shota's Capturing Weapon and lets himself be pulled in close so that he can activate his own quirk.

Tomura blocks Shota's elbow strike with his left hand and as he taunts the Pro Hero, Tomura partially disintegrates Shota's elbow and inflicts heavy damage to his arm. Shota counters by punching with his free arm and backs off; dodging the attacks of a pair of nameless villains as he does so.

As Shota gains some distance, Nomu suddenly appears from behind and deals a heavy blow that breaks Shota's goggles. Within moments, Nomu pins Shota to the ground and breaks his arm like a twig.

Shota nullifies Nomu's quirk by looking at him and realizes that Nomu's superhuman strength is his own base strength and unrelated to his quirk. Nomu simply slams Shota's head into the ground as Izuku, Tsuyu and Minoru look on.

Kurogiri arrives and relays to Tomura his failure at stopping Tenya from escaping the scene. Tomura is dismayed at the news and threatens Kurogiri's life but calms down and admits that they have to retreat at the prospect of fighting multiple Pro Heroes. He decides that before they leave, however, they will scar the Symbol of Peace's pride by killing some of his students.

He quickly rushes at the observing Izuku, Tsuyu, and Minoru and attempts to use his quirk on Tsuyu by grabbing her face but Shota intervenes at the last moment by nullifying Tomura's Decay. As Shota's head is slammed back into the ground by Nomu, Izuku quickly leaps out of the water and aims a punch at Tomura to free Tsuyu.

The punch connects and Izuku realizes that his arm is unbroken. He looks up to see that his punch connected with Nomu, not Tomura, and quickly winds up in the grip of the villain who prepares to attack him back. Tomura reaches once more towards Tsuyu and Minoru while Tsuyu's desperately extends her tongue to save Izuku.

Suddenly, the doors to the U.S.J. are broken off their hinges and All Might enters the facility, interrupting the battle.

Aftermath
Shota's serious injuries would have a lasting effect on him that would keep him heavily bandaged during the entirey of the U.A. Sports Festival. Even after he recovered back to fighting condition, his quirk lost some of its effectiveness due to his head injuries.
