Aizawa took a sip of his drink, the moment he realized that his quirk wasn't working was around the same time that he just gave up and decided to enjoy the show. The unchecked chaos of his class had finally reached critical mass and was slowly growing to consume everything. The gym his students had used for their concert burst like a pimple, growing in size and enlisting more and more of the campus like some kind of insidious infection of concrete.

The structure took shape quickly, a massive stadium, already the size of the one they used for the sports festival and growing by the second. Every student, faculty, and attendee was here filling the seats as they formed, but they only made up a fraction of the audience. Demons and the long dead marched from the hellish wound in the center of the stadium, mingling with the living like it was no big deal, every bit of conversation was on the battle yet to come.

The heavens split open, bathing the night sky in a pure light. Winged humans twice as tall as the average man began to fly downward their endless ranks filling the growing stadium with ease.

With a growl, Aizawa turned towards the source of all this. There was no one else it could be whenever there was a shit show; Izuku was always the star of it all. He tried once more to deactivate the boys quirk. But again nothing happened.

"Fuck yeah!" Nezu, his annoying boss of a hamster let out a scream that could probably be heard all the way across the stadium now. Part of Nezu's face was died green and he had somehow grown a foot long mohawk in the last few moments while donning a leather vest.

The frenzy in the air was palpable. Even the more reserved people he had come to almost respecting were giving into this debauchery. Vlad was head banging, Present Mic was literally fangirling over some of the players, and even Endeavour was looking like a rocker wearing a flaming leather vest and riding a motorcycle around the free way that now circled the stadium to support getting from one side to the other. The entire campus could easily fit inside the stadium now, and it was only growing more.

"Aizawa." All Might came running up to him, the pale sickly man didn't look so good at the moment, sweat was pouring down his face. Was this because heaven was open? Was All Might going to pass on now. "I feel…"

All Might buckled over clutching his stomach.

"You feel what?" Aizawa asked resting a hand on his coworker's shoulder.

"I feel…" Those were said through gritted teeth as his entire body began to pulse. "I feel..." All Might burst free from his tracksuit, a leather vest barely covering his massive musclely form as he returned back to his prime, his normal V shaped hair now a wild afro of spikes as shining chains wrapped around the heroes wrists. "PLUS ULTRA!"

"PLUS! ULTRA!" The stadium roared back.

All Might revved a Harley that wasn't there a moment ago, blue flames of lightning came out of the exhaust as the engine roared with a thousand thunderstorms contained in a bottle. All Might held up a fist and rode off the balcony of the stadium, his bike flying like a chariot drawn by lightning.

Aizawa sighed and pinched the bridge of his nose. He was an idiot for showing any sympathy.

"Yo, Eraser!" Joke grabbed onto his arm, her black bandana keeping her green hair back. She looked good in black. And how were her breasts staying inside that corset? "You wanna fuck?"

"No!" Mandalay grabbed onto his other arm and held him tight. She was dressed in similar clothes to Emi, though he was more confused how her large breasts were staying inside the open leather vest she was wearing. "He's going to be with me tonight."

"Oh, we can share," Joke offered.

All Might arrived into the middle of the field, it felt like the whole world was cheering as he grabbed a microphone of raging waters, blazing flames, sparking thunder, and roaring winds. "Are you ready to rock!?"

The crowd erupted, their unison voices shaking the earth.

Fuck it. It wasn't fun being the only sane one it was boring. Besides, apparently he got to have a threesome, that was two more people than he ever had before.

"Plus Ultra!" and just like that Shota Aizawa joined in the revelry.

XXXX

For a while there, things had gotten so crazy that they just started to make sense. Of course, David Fucking Bowie would appear out from the earth and challenge Izuku to a rock battle, and of course, they would be facing off against other famous rock stars like Freddie Mecury, Jimi Hendrix, and even Elvis Presley. Then the gym changed into a stage, their classmates finding seats in the stadium.

It felt normal.

But then the crazy got kicked to eleven when All Might showed up in the middle of it all looking like he had just given a god of thunder the best blow job of all time in the middle of a leather and bike shop.

Kyoka held onto her guitar, well it wasn't really her guitar anymore, it looked like it was made of fire that didn't burn her. All of the bits were still there, but it felt warm. Really fucking warm. But it didn't hurt her. So far her clothes were still the same, but she now had a mohawk. Which was as awesome as it was tacky.

Behind her that adult Eri was all but vibrating as more and more drums got piled around her like she was sitting on a throne of percussion instruments. Behind Eri was an even larger drum set, with giant floating drum sticks matching Eri's every movement. The girl, woman, or whatever the hell she was looked to be bursting with excitement.

And speaking of bursting with excitement, Momo was barely holding on. Her face was flushed red, and her leg was spasming the same way it did when she had an ever so slightly too intense orgasm. The girl looked like she was completely lost to anything, and that her mic stand probably had more sexual experience than most of the people in the stadium. Well, besides the rock stars.

Momo kept looking towards Izuku, her unasked question being if she could sing, or if they could just start fucking again.

Then there was Izuku. He was standing at their lead practically the epitome of everything rock and roll in one shirtless short little beef cake that was absolutely killing it in leather pants. God, she wanted to be fucking him right now. Wait, could she fuck him and play at the same time? How would that work?

And wait, where was Izuku's guitar?

And was he floating? That was hot.

"Alright!" All Might boomed screaming into his microphone of pure chaotic rock energy. "Without further adieu! Let's get this show on the road! Today, we are going to have a rock battle for the fate of the world! Representing those that slither in the dark! The creeping temptation and all things sin! We have the lord of hell himself, Lucifer! Better known as David Motha Fucking Bowie!"

It felt weird hearing All Might swear.

The crowd roared, humans, demons, angels, and everything in between screaming like fangirls.

All Might then pointed towards them, more specifically Izuku. "Aaaaaaand representing, humanity! Freedom! And justice! We have Izuku Midoriya!"

It was impossible to tell which cheer was louder, or where one cheer began and one cheer ended, one thing was for sure it felt like the entire population of Tokyo was cheering this whole thing on.

"Let us begin." David Bowie's criminally smooth voice was loud and clear despite the half mile or so between them, though he did not shout.

Music came pouring out from the opposing band, all the talent gathered there joining into one harmonious voice crying out for sweet sweet victory. It gathered around them, coiling, bubbling and taking on a red hue that reverberated throughout her entire being.

Kyoka gasped, feeling her knees go weak at the presence. It was a giant red snake that wanted to devour her and swallow the entire world. This was what they were up against. How on Earth could they-

Green energy erupted from Izuku, his fingers dancing across thin air. He was playing the absolute best air guitar that had ever existed. It was the best because it was real, she could feel it, every string, every chord reverberated in her soul, making her feel more and more alive, more and more like playing her guitar.

So she did.

That first chord was pure freedom. Her energy joining and being amplified by Izuku's own energy to become something greater than the sum of their parts. Eri's drums joined in, the sound of a rebellious march thundering with the sounds of shattered chains. It made her want to play more. Play better. Play harder. Her guitar ignited growing from a campfire to a blaze that surrounded her, enveloping her in a smoking hot dress of flames that left her clothes little more than ashes.

Alright, so she was wearing a dress of fire, that was pretty awesome. Hopefully it didn't rain. But with Izuku's playing summoning thunder, she didn't have high hopes.

Momo stepped forward, her entire body twitching as she waited for her part. The swirling green energy around them that protected them from the snake was funneling directly into her. She lurched forward, her laughter barely heard over the roaring tsunami of their music. She grabbed the mic, holding it just above her as she leaned forward like she was in pain.

The scream that followed set the tone of their song.

It was one of passion, of purpose, of joy, of all those wonderful things that made Momo, Momo. And there was just a splash of orgasm in there. Okay, there was a lot of orgasm. Kyoka couldn't see Momo's face but the girl was stroking her cheek like she was currently in the throes of pleasure.

"Am I brave enough? Am I strong enough? To follow the desire that burns from within! To push away my fear to stand where I'm afraid! I am through with this, cuz I am more than this." Momo let out a laugh that matched the melody; she was wrapping the song up in around herself, its flames licking at her heals as she took the lead from Izuku, her voice the absolute in all of this. She ran a hand through her hair, the black color of her hair falling like ashe as her hand left a trail of blood red hair.

Momo looked fucking hot as a redhead.

"I promise to myself alone and no one else!" Sparks formed on Momo's back, burning at her shirt. Two nubs appeared, burning and glowing with sparks and cinders, growing inch by inch like a candle burning in reverse. Feathers appeared from the flames. Once the flames reached the tips, two red angel wings erupted from Momo's back. She took to the sky, flying as easily as she walked. Graceful, elegant, and drop dead gorgeous. "My flame is rising higher! I am the fire! I am burning brighter! Roaring like a storm!"

Kyoka wanted to join her. She needed to join her! Wings erupted from her back. Black, leathery, bat like wings of a demon. She wanted to know if her hair changed color too, but she needed to be with Momo now. With a single flap, she took to the sky; it was easier than walking, riding the song like she breathed to meet Momo in the air.

Momo's black eyes met hers and they were so full of love and life. Momo held the mic between them.

"You're the one I've been waiting for! Screaming like a siren, alive and burning brighter!" Kyoka sung, her voice mingling with Momo's like they were having sex. Right there in front of millions of people. In front of the entire world.

Izuku joined them, wingless, shirtless, his fingers still shredding the very fabric of reality. The energy around them began to grow, it's features becoming more pronounced, more animal like, a massive green eye appeared and looked towards the snake that David Bowie had created.

All three of them together sang as one.

"We are the fire! We are burning brighter! Roaring like a storm! You are the one I've been waiting for screaming like a siren! Alive and burning brighter! We are the fire!"

Bursting from the coil, their energy took the form of a mongoose, it's lithe form dancing around creation with ease. It leapt forward snatching the snake in its jaws and snapping it instantly.

"Well done." David Bowie's voice drifted into her head once more. "This world shall know peace, Izuku Midoriya. Well done."

The music stopped. The stadium vanished, and everything felt like it had been hit with a reset button.

Save for her, Momo and Izuku falling back down onto the stage to the roaring applause of their now metal head classmates. Even All Might was still rocking his rocker bike look. Just without the lightning.

"Woo!" Eri cheered from behind them. "That was fucking awesome! Totally worth it!"

"That was amazing!" She managed to hear the smaller Eri looking over at them from her spot in the crowd.

Kyoka stood, vaguely aware that she still had her new wings and that she was now very topless. Someone was quick to throw her a towel. And wait, why did she have a devil tail now? Did she have horns? She poked around her head. Yep. She had horns now.

Momo followed suit, one hand going to her wing while the other covered her chest. "Well that certainly was something. But these are going to take some getting used to. And the hair."

"You look good as a redhead." Izuku stood smiling at both of them. "And I like your horns, Kyoka."

"Ahh, oh well umm, thank you, Izuku."

"I can change you back if you want." Eri popped over, humming and looking completely unphased by everything. "But I like them too."

"Oh well then, I guess I could give them a try." Momo flapped her wings softly and looked at her hair once more. "I'll have to consider if I want to dye it or not later."

"Right later." Eri hummed placing both hands behind her back. "But uhh, how about that four way now?"

Whatever grace Izuku had moments ago, vanished and he promptly fainted with a blood nose.

When he woke up, they did have that four way.

AN: ROCK ON! Hope you all enjoyed this pure insanity.
