Rumi Usagiyama vs. High-Ends

Mirko vs. High-Ends is a battle between the No. 5 Pro Hero Mirko against four High-End Nomu.

Mirko attempts to reach Kyudai Garaki and Tomura Shigaraki while the High-Ends defend them.

Prologue
During the early stages of the police raid on Jaku General Hospital, Mirko goes ahead of the other members of the Hospital Raid Team in order to find Doctor Garaki's secret laboratory as quickly as possible. The Rabbit Hero rushes through the morgue of the hospital and is confronted by several Nomu. She relays the incoming enemies to her allies as another large swarm of Nomu attack them at the same time.

Mirko enjoys the wild rush of battle and strikes her way through all the Nomu impeding her path with a furious barrage of kicks. Combined with her incredible speed, the Rabbit Hero's flurry of kicks cuts through all the Nomu and she's able to burst into the mad scientist's secret lair just before he's warped to safety.

By blasting through the wall of the lair, Mirko crushes the little Johnny Nomu, preventing it from using the Warping Quirk and ultimately killing it. Mirko asks if this Doctor Garaki is the genuine article while the evildoer screams in terror.

The impact of Mirko's entrance not only killed Johnny but shattered several tanks of Nomu and Quirk duplication equipment. She radios to Endeavor and tells him that she found the Doctor and a bunch of peculiar-looking Nomu. The No. 1 Hero asks Mirko to capture the Doctor.

The Rabbit Hero rushes at the Doctor and prepares to deliver a strong kick, but another small Nomu stops her from doing so. She kills the Nomu with a single kick, but this buys the Doctor just enough time to activate the High-End Nomu within his lab.

Battle
Five High-Ends suddenly burst out of their containment tanks and attack Mirko. Woman manages to send Mirko flying back with a straight open-handed strike to her face, senting her crashing into the area above her opponents. but not before Mirko kicks off her other hand and the arm of Chubs.

After regenerating their lost limbs, both High-Ends begin to speak, commenting that they have faced a hero. All the High-Ends realize they've been awakened and express their excitement to go wild a fight heros once more. Just then, Crust arrives at the lab in horder to help Mirko, but Chubs recognizes him and charges at him, pushing him out of the lab and blocking the entrance in the process. Mirko frees herself from the tubing in the wall and despite her injuries, taunts the Doctor for fleeing into the inner sanctum of his lair. Excited for a good fight, Mirko claims things are just getting heated up.

The Rabbit Hero surmises that the Doctor is trapped inside that section of the lair and decides to taunt him. The High-Ends are surprised to see that she survived the initial attack. Mirko jumps at her opponents and reveals her own legs canceled out the impact. She leaps clean over the Nomu and makes a mad dash for the Doctor.

Ribby attacks her with tentacles that come out of his head, but Mirko dodges it and continues running between the capsules. Eleph comes out in front of her to stop her, but the hero evades the High-End and keeps running. She also dodges Woman's attack, but in doing so she ends up in front of Eleph again, who attacks her with his trunk, but Mirko manages to deflect the attack with a kick.

However, Mirko is caught in Ribby's tentacles, and Eleph and Woman instantly converge on her, as the Nomu reveal their orders are to brutalize the enemy. The Rabbit Hero flips her torso downward, shifting her legs upward, allowing her to block both Nomu from landing a hit. Ribby attempts to restrain her with his antennae-like Quirk, but Mirko tears through the tentacles and strikes the other two High-Ends at the same time with her Luna Ring Ultimate Move.

The tentacles are able to throw Mirko's aim off, so her vertical spinning kick landed too shallow of a blow to put down the Eleph and Woman. She turns her attention to Ribby and blitz's past it's tentacle attacks, blasting them apart with incredible speed in the process.

Mirko maneuvers herself behind and above her target and prepares to deliver a fierce downward kick. However, the Robot uses a spatial distortion Quirk to destroy Mirko's forearm completely. The No. 5 Hero's intense willpower allows her to ignore the pain. Ribby attempts to inflate it's back and reinforce its defense with bones. Mirko breaks through its defense but is unable to land a direct hit to the head, even so, she lands a powerful blow with a second Ultimate Move: Luna Fall!

Directly afterward, Mirko flips rapidly at Robot and prepares to get its head in a scissor hold. The helmet-headed High-End is surprised by her undaunted attitude and the No. 5 Hero reveals that she knows those who fight at long range are sorry fighters in close quarters. Robot attempts to retaliate with its laser eyes, but Mirko simply dodges, stating that she will die when its her time. Using her Luna Tijeras Ultimate Move, Mirko severs the High-Ends head with a powerful scissor kick maneuver.

Using strands of her hair to apply a tourniquet to her amputated arm, Mirko turns toward the other three High-Ends, stating that now it will be easier for her to deal with them now that he knows that he can defeat them permanently by crushing their heads. She also declares that she lives her life everyday like there's no tomorrow for her so when it's time for her to die, she'll have no regrets, and that a bunch of mindless Nomu will not be able to kill her.

As the fight rages on, Mirko starts to lose the upper hand. She begins missing all her attacks and realizes it's not the result of her injuries, but the result of the Nomu are finally awaken. Even with as much fun as she's having, Mirko prioritizes the mission and attempts to make a direct line for the Doctor using her speed.

Ribby uses his sharp antennaes to stop her, slashing her side and tearing off a part of her right ear, but Mirko continues to run, ignoring her injuries. Then eleph grabs her by her hair at the same time that Woman bites her left leg. Nevertheless, Mirko presses on and continues running, telling herself that if she is going to die, she will do so after she has accomplished her goal. Mirko makes it through the small tunnel and comes flying into the inner sanctum with the full intention of destroying the holding tank with Tomura Shigaraki inside, with Kyudai alongside crying out in fear.

She is about to destroy the tank with her leg, but Ribby manages to pierce her lifted leg with his antennae, also slashing off a piece of her face as well, and prepares to pull her back. Even so, Mirko refuses to give in because she knows a hero never ever gives up. Thanks to the arrival of Endeavor, Ribby is taken care of and Mirko is able to reach Tomura's tank.

As Mirko approaches the tank, she can feel her Rabbit instincts screaming to her that Tomura is a serious menace now and he can't be allowed to wake up, hitting her leg on the pod, shattering the front but not completely destroying it. Woman is able to free their tentacle-headed ally from Endeavor's grasp, allowing Ribby to attack Mirko again, piercing her lower leg and right arm and pulling her away.

With all her willpower, the Rabbit Hero ignores the pain and manages to burst Tomura's tank using her Ultimate Move Luna Arc, much to Dr. Garaki horror. However, Mirko curses as she is dragged away by Ribby, since she hasn't been able to fully destroy the capsule. The High-End Nomu violently throws Mirko at Endeavor to get him off his back.

Once saved, Mirko yells for everyone else to keep fighting to stop Tomura from awakening at all costs.

Aftermath
Following her critical role in the fight, Endeavor brings Mirko to a safe space and cauterizes her wounds closed to stop her from losing too much blood. The No. 1 Hero thinks to himself about how its only been five minutes since she radioed into him and surmises that she fought multiple High-Ends all alone.

Dr. Garaki works desperately to fix the damaged pod system, stopped at 75% completion, as he is still trying to wake Tomura from his slumber. Woman finds Endeavor and attacks him. At the same time, Mirko radios to Crust and the others, telling them not to let Tomura awaken the same way the High-Ends did. Before long, reinforcements from the rest of the Hospital Raid Team arrives and restrains the High-End, allowing Endeavor to deal a finishing blow.
