U.A. Team vs. Tomura Shigaraki is battle taken place during the Final War between a team made up of Heroes and U.A. students against "Tomura Shigaraki".

Prologue
In order to defeat "Tomura Shigaraki", the Heroes are not only aware that they must separate him from All For One so they can not assist each other in battle, but they also have to face him in a terrain where he cannot take advantage of his multiple Quirks. For this, U.A. High School is transformed into a floating fortress with all sorts of measures designed to counter Tomura's powers, also known as the "Coffin in the Sky".

This version of U.A. has disposable parts to prevent the Decay from spreading, with various students and heroes taking charge of repairing and replacing the damaged parts mid-battle. The battlefield is surrounded by an electromagnetic barrier to prevent "Tomura" from escaping. Outside said barrier is an electricity generator, which houses the students capable of producing electricity, including Chargebolt, Comicman, and Yuyu Haya, powering the barrier and keeping the fortress afloat.

As part of the hero force in charge of fighting "Tomura" head-on, Deku is set as a key role in the strategy to defeat him, as the bearer of One For All. Lastly, Phantom Thief copies and learns to use Kurogiri's Warp Gate Quirk so that they may catch the Villains off guard and separate them.

When everything is properly prepared, the heroes lure All For One and his allies into an ambush using Can't Stop Twinkling and Deku as bait, and with the help of containers, the heroes divide the villains into smaller groups and push them into portals created by Phantom Thief, sending them to the assigned areas.

As planned, Tomura alone is sent to U.A., but the first failure of the plan occurs when Deku was dragged into a different portal by Himiko Toga, ending up on Okuto Island, two hundred kilometers off the mainland. Dynamight, who was with him, warns Best Jeanist that something went wrong and Deku isn't there.

Battle
Best Jeanist asks what happened, but Dynamight only says that Deku was taken away somewhere else. Suneater worries about this setback and Nejire Chan suggests they warn everyone. Only Mirko doesn't seem to care about the situation and the only thing they should focus right now is facing "Tomura".

As the heroes rethink their strategy, Tomura figures that he is in a floating version of the U.A., in addition to none of the escaped convicts or members of the Paranormal Liberation Front being there, so he has to deal the heroes alone. Without giving too much importance to his situation, and telling his "other self" not to interfere this time, as soon as he lands, Tomura touches the ground and begins to destroy everything with his Decay.

However, the disposable part placed underground launches up skyward to harmlessly disintegrate to nothing, preventing the Decay from spreading. This also launches Tomura into the electromagnetic barrier, severely electrocuting him. Tomura tries to recover from the shock but before he can do it, Best Jeanist uses his Fiber Master Quirk to ensnare him with wires and slam him to the ground.

It doesn't take long for "Tomura" to break free, and as he avoids being captured again, he understands the strategy the heroes are trying to employ, taunting Best Jeanist that sooner or later they're going to run out of terrain. The hero simply replies they are never short of resources, showing him how new parts fix the area affected by Tomura's Quirk. Jeanist tells "Tomura" that the arena was constructed with the purpose of cornering and neutralizing him.

Inside the huge floating building, numerous professors and students from U.A. are working tirelessly to constantly repair pieces destroyed in battle: Power Loader reports about the destroyed metal plates, while Cementoss and Ectoplasm manage the Development Class to provide new pieces to fill the gaps. Creati uses her Quirk to produce a near-limitless amount of material to supply them with, being aided by Lunch Rush, who constantly prepares meals for her so she can using her Quirk endlessly.

Back on the surface, Best Jeanist continues his speech saying to "Tomura" that no one is fighting for honor or glory, but to stop the doom he brings. All the heroes go after him, so "Tomura" decides to shoot a shockwave to destroy the forcefield and the electricity generator on the other side, only to find out that he can't use any of his Quirks.

Turns out, standing atop the power room, Phantom Thief is using Erasure on him, with Eraser Head and Manual accompanying him; the former is in continuous contact with the Class 1-B student to circumvent his time limit for copied abilities, while the latter uses his Quirk to wet Phantom Thief's eyes so he can keep them open and on "Tomura". Despite only having one eye left, Eraser Head also contributes as best he can by using his Quirk, but he laments the unavailability of Deku has caused a halt in their plans.

With all his Quirks blocked, Tomura is at the mercy of the heroes, who pounce on him, but then something totally unexpected happens: "Tomura"'s left hand suddenly begins to transform into a grotesque amalgamation of fingers. This catches the heroes completely off guard, as he has never displayed such an ability previously, and before they can react, "Tomura" attacks Mirko with it, since she was the closest.

However, the attack does not end there, as the grotesque swarm of fingers continue to grow larger and larger, overrunning U.A. and causing great damage in its path, destroying one of Dynamight's Grenadier Bracers and some of Mirko's prosthetics. The Heroes ask Phantom Thief if Erasure is working to which he assures is still in effect, which means Tomura's new power does not come from any Quirk, much to their confusion.

"Tomura" confirms that his ability is just a natural growth of his body, similar to the growth of nails or hair, as his body is adapting and mutating to accommodate the power inside him, an outcome predicted in Dr. Kyudai Garaki's Quirk Singularity theory.

By losing her prosthetic right leg and left arm, Mirko managed to avoid Tomura's unforeseen attack, and immediately calls in for spares that arrive from below the battlefield. Once she's back in action, she orders Dynamight not to act too recklessly, something he doesn't take too well, starting an argument between the two that ends when Best Jeanist tells them to stay focused.

A worried Phantom Thief swears that he hasn't made any mistakes using the Erasure, with Eraser Head assuring him that he hasn't done anything wrong. Mandalay appears to report they've gotten into contact with Deku. He apologizes to his teacher for being dragged off by Himiko on Okuto Island and requests being warped to U.A., before being interrupted by the fighting.

Unfortunately, the heroes are aware that this will not be possible. Phantom Thief can't use two Quirks simultaneously, and each of innumerable growing spreading fingers that sprout from Tomura's arm has the potential to use Decay. This means that if Phantom Thief shuts using Erasure to bring Deku there, Tomura will take that opportunity to destroy the entire battlefield in one go. Considering the situation, Eraser Head tells Deku to get to U.A. on his own. Until then, the heroes declare that they will strive for victory against "Tomura", even without One For All.

Despite their boast, it is clear that the heroes have trouble dealing with the gigantic and misshapen mass of hands and fingers, not being able to do anything but dodge when it comes at them. Suneater is almost crushed by one of the tentacles, while Nejire Chan tries to hold another one back with her Wave Motion Quirk, having to move away when another tentacle attacked her from above.

The other heroes also dodge the waves of flesh, with Best Jeanist using his Quirk to move Dynamight away, who got a spare Grenadier Bracer to replace the one that was destroyed. Best Jeanist reminds everyone to keep moving to avoid being swallowed by the masses of flesh, while searching for Tomura's main body. On the bright side, he also warns them that although the hands are a massive threat, while they are active "Tomura" can't use his All Might-esque mobility.

Edgeshot uses his Ultimate Move Pulp-Thread Throttle to take a huge chunk of fingers and hands with the attack, only for more to grow in its place. Seeing this, he doubts such power is a simple "growth" and not be produced by a Quirk.

"Tomura" simply responds that it's the result of his body adapting to be able to stably contain the All For One Quirk and all the other Quirks inside him. He continues his speech declaring that with his power he will create a new world where he will end inequalities and the rejection caused by lack of understanding, having every subjected under his rule, mockingly asking the heroes if world peace isn't what they yearn for.

Dynamight responds that, even though he doesn't know if he's currently Tomura or All For One, he's sick of his speeches, and activates "Suppressive Heavy Mobile Unit: Strafe Panzer". Several guns come out of his his new support item and he starts shooting wildly, blasting large chunks of deformed flesh in his way towards "Tomura".

Thinking about all the heroes and his classmates who are giving their all, and recalling the time Izuku saved him and Tomura's words about lack of understanding results in fear and rejection, Dynamight yells the villain he already saw the real steps to overcome such issues. Seeing his trainee tearing straight through Tomura's fleshy defences delights Best Jeanist into using his full hero name. Dynamight manages to get close enough to "Tomura", unleashing a direct hit with his new Ultimate Move, Howitzer Impact: Cluster.

Dynamight's point blank explosive attack is so powerful, it reverberates throughout the fortress, being felt by both those inside and outside. Unfortunately, when the dust clears, it is revealed that "Tomura" has only been singed off the right side of his face. The villain managed to deflect most of the blast by grabbing Dynamight's right arm, wounding him in the face in the process, with his right eye bleeding.

"Tomura" commends the injured Dynamight for concentrating his explosion so as not to harm others. He then crushes his arm and begins to generate a new wave of fingers to finish Dynamight off, reminding him what he told to him last time: he is no longer interested in him or his growth.

Mirko, Best Jeanist, and Edgeshot rush to Dynamight's aid, but "Tomura" mocks them for rushing in and thinking they can deal with him in close quarters. Throwing Dynamight to the side, he attacks with his mass of fingers and the shock wave generated is enough to knock down all three heroes.

Dynamight is stunned at Tomura's sheer power, as "Tomura" starts to move towards him, clarifying that the only thing that interests him about him is his friendship with Deku. Concerned about what is happening on the battlefield, Eraser Head asks Mandalay for Deku's status, but she informs him that they unable to reach him, as the static outside is currently preventing any communication. Eraser Head can only watch helplessly as Tomura approaches his student, desperately yelling for someone to help him.

Elsewhere in the rubble of the U.A. building, Suneater expresses to Nejire Chan he would like to have a proper graduation ceremony. A voice tells him that they will only have to ask Nezu once everything is over, but Suneater replies if they have a chance. Emerging from the ground, Lemillion motivates them to fight as The Big 3 once again, in order to protect everyone until Deku gets there.

As they jump into action, Lemillion asks Suneater and Nejire Chan to keep "Tomura" busy while he uses his Permeation Quirk to get close, and rescue Dynamight. As soon as he succeeds, he will then be in charge of keeping "Tomura" busy, in order to give Suneater time to prepare his attack.

Stepping on his head, "Tomura" rhetorically asks Dynamight where Deku is and that it shouldn't take long to reach them. Dynamight attempts to retaliate with his Strafe Panzer and the last remaining Grenadier Bracer, but "Tomura" effortlessly stops him by using his toes to grab his hair and lifts him up, grabbing him by the neck and causing his Strafe Panzer to miss the shoots as he shatters his last Bracer. The villain mocks Dynamight, remembering back to when he seriously injured him in their last fight and how enraged Deku became, planning to use his corpse to welcome Deku back to U.A., taunting the boy he can never surpass "One For All".

Nejire Chan then appears behind "Tomura" and attacks him with her Nejire Wave: Pike. "Tomura" holds Dynamight in front of him as a shield, forcing Nejire Chan to redirect the attack at the last minute. Still, this leaves "Tomura" off guard, and using his Vast Hybrid technique, Suneater sneaks up on him with Octopus Mirage and uses Scorpius Toxin to sting his back with two scorpion tails and inject venom into him.

However, "Tomura" mocks their efforts as pathetic, growing a mouth along his shoulder to expel the toxin from inside him. He then manifests another rapid flesh growth, forcing Suneater back. The villain gloats that his body is constantly adapting, and they can't bring him down.

This turns out to be primarily a distraction, as Lemillion uses his Permeation Quirk to pass right though "Tomura's" attacks and get Dynamight away from him, throwing him back towards Best Jeanist so he can take care of him while he and his teammates deal with "Tomura". The villain remembers him from the last War and he introduces himself as Lemillion.

While evading his fleshy tentacles, he asks the villain why he is hellbent on destroying everything, which he responds is because the current systems have failed. Lemillion is determined to hold him back however long he has to for Deku to arrive, knowing he isn't strong enough for it but fortunately he has backups.

Outside of the chaotic fleshy masses, Nejire Chan peers for an opening, until she spots one and fires a Wave Motion that wraps around Lemillion's right hand, just as he replies to "Tomura" that his explanation is why he never had any friends, which confuses the villain to hear. As he lands a point blank punch empowered by Nejire Chan's Quirk on "Tomura"'s body, Lemillion declares that if he did have friends, he'd know there's plenty worth keeping around.

Meanwhile, Best Jeanist tries to take care of Dynamight's broken right arm, since they still need his fire power. When his former trainee doesn't seem to react, Best Jeanist thinks his spirit is broken by the overwhelming power of Tomura, and tries to console him by saying that their foe is on a different level altogether. But then, he hears Dynamight whispering, eyes fixated on the the ongoing fight. Best Jeanist is shocked when he realizes that Dynamight is actually using his analytical skills to predict Tomura's twisted moves, showing that he is far from being broken, and intends to continue fighting.

Back to the fight, "Tomura" seems aggravated by Lemillion's words that he doesn't have any friends. Such accusation actually manages to get through to him and causes the part of his personality that represents "Tenko Shimura" to momentarily break free of All For One's control, taking control of the body to shout out hysterically at Lemillion that he really has friends.

Surprised by this outburst, Lemillion immediately apologizes for his words, before dodging another wave of flesh. While evading the monstrous fingers; Lemillion wonders what caused such unexpected reaction. Either way, he is concerned that "Tomura's" body is way tougher than the hand tentacles, as his previous wave-boosted punch barely caused any damage.

Meanwhile, All For One's personality regains control of "Tomura". He is noticeably unsettled by the momentary lapse of control despite him and Tomura Shigaraki having merged and become one, and realize that there's still a component within that hasn't been assimilated yet: Tenko Shimura, the childhood self of Tomura before his Quirk awakened. He judges that dragging the fight out is not ideal, so he decides to walk towards Dynamight, ignoring Lemillion who he knows is just trying to buy time.

Best Jeanist steps up to face "Tomura" in order to protect Dynamight. "Tomura" scoffs at his efforts, stating that the huge battlefield they built to contain him will actually be their tombs. Nejire Chan appears and shoots several Pikes at him, but the villain just protects himself and counterattacks by generating more flesh tentacles. Nejire Chan tries to dodge them the best she can, and although she suffers some injuries, she doesn't stop attacking.

In actuality, all those attacks were to keep "Tomura" distracted, and give Suneater time to prepare his Ultimate Move, the Plasma Cannon. Unleashing the full power of his Manifest Quirk, Suneater combines the traits of various aspects and characteristics of animals and plants he has eaten for the occasion to generate a gigantic organic cannon. Nejire Chan then fires one of her Wave Motions directly toward Suneater, which he absorbs and amplifies, providing enough energy for the shot.
