A few days had passed and it was finally time for something different for the students.

Rescue training.

"This time, All Might, myself, and one other will supervise. Preparing you for disaster relief, from fires to floods."

"It's rescue training!" The students yelled quite enthusiastically. After a bus ride of Bakugou getting told he wouldn't be a likeable hero, Midoriya that his Quirk was similar to All Might's, Kirishima being told he has a great Quirk, and Aoyama getting told that he'd be a great hero as long as he doesn't blow his own stomach up, the group arrived at their destination.

While Aizawa got of the bus and led the students inside, he checked his phone for a moment to see if he had any messages from either All Might or Lightbringer, there was none of the above. The man stood there while listening to Thirteen explain what everyone would be doing in the Unforeseen Simulation Joint, or simply put, USJ. Then he realized that All Might wasn't present, so as Thirteen finished speaking, he approached the Pro Hero.

"Thirteen, where's All Might? I thought he was meeting us here." He asked, eyes darting around the space once more to see if he was simply late and coming in now.

"It seems he just about reached his limit during his morning commute." With those words and the three fingers Thirteen held up, Aizawa knew he wouldn't be showing up. "He's resting in the Break Room."

"The height of irrationality." He sighed. "So be it. Let's get started. I know someone else who's done a lot of rescue and may be willing to come in to fill All Might's absence." Thirteen nodded at the mans words while Aizawa walked off a bit to the side and called [L/n], who in the beginning focused a lot on rescuing by lighting up the darkest of places in order to find victims.

While the phone was ringing and he heard Thirteen explain his Quirk to the students, he realized a huge similarity between Thirteen's and [L/n]'s Quirks: simple, but could easily kill those around them.

Just as [L/n] picked up the phone, things began to go downhill.

As a swirl of wind began to appear in the center and a portal appear, or rather a warp gate, a man that appeared to have a hand for a face came out.

"Huddle up and don't move!" Aizawa yelled, never hanging the phone up, the phone in his pocket leaving the person on the other end to hear everything. "Thirteen! Protect the students!" Pulling up his goggles as more and more villains came in, he prepared to fight. With just himself and Thirteen, he didn't know how it would go, but he had no choice.

They needed to win, to protect the students.

"Shouta, Shouta are you there damnit!?" [L/n] yelled through the phone, but the connection was soon cut off. Gritting her teeth, she did the one thing she could. Bending her knees down and heels up, the wheels on the bottom of her boots beginning to spin, she placed her heels back down and took off leaving a trail of light in her wake. Her destination: the USJ.

"Thirteen! Begin evacuation and try calling the school! One of these villains must be jamming the sensors. There's a good chance one of their electric types is causing interference. Kaminari, try using your Quirk to signal for help." Aizawa commanded, the capture scarf around his neck already beginning to flow.

As he was about to launch towards the villains, Midoriya spoke up. "But Sensei, you can't fight them alone! Against that many... even you can't nullify all their Quirks! As Eraserhead, your fighting style involves Erasure and a quick binding capture, head on battle isn't—!"

The man cut him off rather simply, "No good hero is a one trick, pony." With that and one last word to Thirteen, he took off. 

As he began to fight, taking villains down one after another, he could hear one yell, "You dumbasses! He can cancel out your Quirks just by looking at ya! That's Eraserhead!"

"He cancels Quirks!? Heh heh heh. Let's see if that trick works against us heteromorphic types!"

"No. It doesn't." The man spoke simply, shoving his fist into the villains face. "Only against operative or transformative types." The villain was blown back by the impact. "However," He ducked down, avoiding another's punch, grabbing his capture scarf and using it to bind the villains. "Statistically, guys like you tend to shine in close quarters combat." He slammed their captured bodies into the ground, retracting his capture scarf. "Which is why I've got counter measures for you."

That's when it happened, when the warp gate villain appeared near Thirteen and the students.

Damnit, in the blink of an eye, he—! He may be the deadliest one here! Aizawa's eyes were wide beneath the goggles, knowing he wouldn't be able to get up there in time, leaving Thirteen and the students trapped with possibly, the deadliest of all the villains present. Not too long after, he observed as the mans warp-like body engulfed his students, and as the mans body retracted, more than half the class was gone.

Shit! Aizawa was caught off guard, but managed to continue taking down the minor villains that just continued to swarm him.

Then the doors opened, only to be slammed and locked behind the person who charged in. Looking up for just a moment, Aizawa saw someone who he just recalled calling minutes ago, someone he didn't hang the phone up on.

Pro Hero Lightbringer, [F/n] [L/n]. Her eyes landed on the small amount of students, Thirteen, and Aizawa continuously getting swarmed. Then she recognized two specific villains, the warp gate villain near Thirteen and the students, and the crusty one a minute away who practically decayed the skin from her shoulders to finger tips.

"Lightbringer!?" Thirteen yelled in somewhat surprise at the Pro Heroes arrival. Squinting, he was able to see her eyes beneath her very, very dark sunglasses, and he didn't like what he saw as her eyes darted between the warp gate person and someone in the distance.

The look of recognition.

"Go down there and help Eraserhead and take care of the rest of the villains, I'll take care of the students!" Thirteen practically yelled as things only proceeded to get worse. Lightbringer swiftly nodded, wheeling off and down towards Aizawa, a trail of light still being left in her wake.

"Eraserhead/Lightbringer!" Both yelled as they became back to back, Aizawa halting Quirks and capturing while [L/n] created spurts of light to temporarily blind the villains.

"It's them, the one's who interrupted our cargo a few nights ago, and the girl who got a feel for my Decay." The villain with a hand on his face spoke rather maliciously.

As more and more villains began to swarm the duo, it was getting harder and harder. [L/n] couldn't fully use her Quirk without burning Aizawa behind her and her arms were still far too injured to use fully either, so she settled with kicks and short bursts of blinding light while Aizawa was facing the other way. This wasn't how they usually fought, and it showed. Midoriya, Mineta, and Asui had just escaped their zone and were watching their teachers begin to struggle, but they couldn't help, not after what was slowly approaching.

The minor villains were done, so while the two launched themselves towards the man with a hand on his face, only Aizawa got to him.

For [L/n], things were different as a monstrosity that appeared to have a beak rammed into her, sending her body flying and violently rolling across the ground.

Meanwhile, the warp gate was causing Thirteen to be ripped apart by his own Quirk.

Aizawa now knew what [L/n] went through as he was pinned to the ground, his clothes and the skin on his elbow beginning to decay. He was more focused on himself until he watched as the monstrosity neared [L/n] once more and slammed it's fist into her body, shattering the ground beneath her.

Midoriya, Mineta, and Asui found themselves frozen in absolute fear.

Looking around herself to make sure no one was too close, Lightbringer illuminated her entire body, becoming made of the exact same atoms of the sun- only a bit more minor due to the intensity of course. As the monster-like creatures fist approached her body once more, it's fist sank into sheer heat, it's outer, what appeared to be skin, melted away and the creature retracted its arm, [L/n] taking this chance to stand up, arms now in a defensive position. They may hurt, but she had no choice.

Both she and Aizawa saw Midoriya, Mineta, and Asui, who were very close to them. They couldn't afford to be beaten and have them go after the students.

Things can always change though, and the good guys don't always win.

As the blue haired man gripped Aizawa's elbow tighter, even more of his arm decaying, he whistled, the creature that he had whispered to be Nomu appeared at his side at an insanely quick speed, leaving [L/n] just standing there.

Her instinct in that moment was to go get Asui, Midoriya, and Mineta and take them away, but that changed quickly as the Nomu had Aizawa's body pinned, arm broken while the man with a hand on his face leaned down and whispered something into Aizawa's ear.

"You see, Eraserhead, while our goal here is to kill All Might, the Symbol of Peace, it's rather convenient to see that the two of you are here, the one's who interrupted our supply just a few nights ago. Everything she felt and that you're about to feel, well, consider it payment." With those words, the Nomu twisted his arm even more, the hero unable to look up to stop either of their Quirks, his head then getting slammed into the ground more than once by the insanely powerful Nomu.

"Look away!" Lightbringer yelled, launching her body feet first, her entire body made up of the same atoms of the sun, towards the Nomu and crusty faced man. While Aizawa shut his eyes and the three students, still paralyzed in fear, also managed to shut their eyes. While her feet made contact with their faces, both the Nomu and crusty faced man were sent back, but not by much. Stopping her Quirk her eyes glanced to the students for a very short amount of time before returning to the Nomu's and mans.

"Get Eraserhead out of here, now!" This was the first time any of them had seen her eyes, with her sunglasses being previously shattered by the Nomu, they could see her [e/c] eyes. [L/n] was being serious, demanding, something that had never been seen on the Unrated Pro Hero before. Snapping themselves out of their fear paralysis, they nodded and grabbed the unconscious hero and quickly began to run.

"How noble of you, Lightbringer. Don't you think that was stupid though? You've already experienced our Quirks and yet you choose to fight alone." She could see the smirk beneath the hand covering his face and it made her feel uneasy as she pulled down the shaded goggles atop her head to make up for the destroyed sunglasses. Her hero costume was already mostly damaged, both wheels on her right boot already broken.

At this point, all she could do was pray.

While two of the kids continued carrying away Aizawa's completely beaten body, Midoriya found himself stopping and turning around— which he both regretted and was glad he did. He knew all about Lightbringer, despite some of her Quirk that was unexplained to the media, and one big downfall for her was that she couldn't do combat that well or fight full-fledged with others around. He didn't know how her arms were injured, but by the bandages and fact she hadn't used them even once, he knew it must've been something more major than minor.

"You come here to kill All Might, destroy Eraserhead's body, destroy Thirteen's body, you aren't making it out of here. That being said, I hope you go to Hell!" Improvisation, a dangerous one at that. Wheeling skillfully on only one foot, she propelled herself at the two, arms out as she activated her Quirk and went to grab the Nomu's skull and hand faced man, but the strength of the Nomu, the speed of the Nomu, could not be beaten, at least not by her.

Because he is on par with All Might, and she isn't. In that moment of hesitation and realization, she stopped her Quirk. Dropping his head down, the blue haired man avoided her hand and grabbed her neck, decaying the skin and threw her body at the Nomu. The result was terrifying.

As it's mouth opened, the Nomu then clamped it's jaws down onto Lightbringer's torso, causing her to unwillingly scream as her blood began to fill both its mouth and drip down it's beak-like jaws. As things began to fade, she heard one mans voice, and one mans words.

"Fear not. I... am here." It was a very tense voice, and the man behind the voice was not smiling.

"I've been waiting, hero." The blue haired male spoke as All Might's eyes landed on the scene around him. Thirteen was destroyed, Eraserhead was being carried away, unconscious, by two students, and Lightbringer, who's body was being held between the jaws of who he didn't yet know to be Nomu.

"I'm sorry, Aizawa." He spoke as he walked past the students carrying his body away. His eyes then landing solely on [L/n] and her bleeding body hanging limp from the Nomu's mouth. The Pro Hero was stuck, if he were to attack the Nomu, he may simply shut his jaws even tighter.

"Nomu, she's not why we're here." He paused. "Get rid of her." With those words, the Nomu began to tighten its jaws, causing All Might to rush into action, hitting the Nomu with his infamous Carolina Smash. The attack didn't hurt the Nomu, but he spit the Pro Hero's body out of his mouth as if she were nothing but garbage, something in its way.

The hero then rushed to grab her body and take her away, but the Nomu delivered a blow that genuinely managed to shoot All Might's body in her direction. Doing the only thing he could, he wrapped his arms around [L/n] so that as they rolled she'd take as least damage as possible. That's when his anger began to build even more, when he could feel her blood seeping through his clothing and onto his skin. 

He didn't have time to take her body away, but he wouldn't be able to fully fight with her there either. Knowing that Midoriya was there, he was going to call for him, but he saw that he was already rushing in his direction.

All Might began to panic, but then another student came out of the blue.

"Damnit Lightbringer, how the hell am I supposed to fight you if you're dead!?" Bakugou roared, blasting himself next to All Might, who released her body so that he could grab it. Going to blast himself back to the main group to give her to the other students, he was almost attacked. However, as Midoriya, Todoroki, and Kirishima were also present, he didn't get hit. 

For the rest of the battle, All Might carried a heavy guilt on his shoulders. From the students being forced to fight, to seeing the bodies of Aizawa's, Thirteen's and [L/n]'s being destroyed.

And the rest was violent, violent, history.
