"Oi. Oi. OI! Isn't this getting a bit too real?" Kirishima asked before Aizawa literally leaped into action, the underground hero hit two thugs on his descent, the thud echoing as the class was still paralyzed with fear. "Go! Call the other pros!" Eraserhead said while he deflected a punch and returned it to the sender with twice the power. He noticed how many opponents were bearing mutant type quirks, 'Great' he sarcastically thought as he dodged another kick before he pulled the leg of whatever lowlife tried to injure him, and tossed him into even more thugs. "I'm only 30, but I'm getting too old for this" he said bluntly while he used his quirk to cancel any possible threats coming his way. 3 grunts charged at him simultaneously, but luckily for him he was able to trip one up with his capture system. Effectively snagging the ones that followed, a muscular grunt looking like a lizard ran up to him at tremendous speeds. "Die!!" He shouted as the latter gave a quick huff before he dodged flawlessly, still fazed from the missed collision, the lizard man was met with a fist straight into his jaw, effectively knocking him out. "One after another" Aizawa said to himself while he saw he was surrounded. "Meet your end! Hero!" First hurdling towards him was a keen fellow wearing pure black, Eraserhead used his capture system to snag his foot. He spun the poor grunt around until he had enough momentum to knock out the other thugs surrounding him. He released the grunt sending the man hurdling into four more criminals. "You're so cool, eraserhead!" The man with disembodied hands cooed at the pro hero fighting off the canon fodder, without using his quirk to boot.

"Go! Call the other pros!" Aizawa called before he launched himself into battle. "Y-You heard him! Class let's get out of here!" #13 said until the black mist blocked their path towards the gate. "I'm sorry children, but we'll be needing your full participation" the eerie yellow glow of the fog's eyes were piercing holes in the psyche of the student body. Almost no one could move, except for bakugo. "Die! You mist fuck!" He said as he propelled himself with explosions from his hands, the momentary flight and loud booms were brought to snap half of the classes trauma, the fear engulfing their chest was lifted as most of them were starting to take fighting stances, flames in their eyes as the boy's entrance was literally a bang. "Bakugo!" #13 yelled at the boy launched himself, then proceeded to send several explosions towards the black mist. The villain gave a hearty and nerve wracking laugh before he stated "Try your mettle, boy. But you won't be hurting me anytime soon" angry yells and grunts could be heard from the explosive teen as he tried to go full Nagasaki on the villain, "Sorry bakugo!" Asui said as she wrapped her tongue around the boy and pulled him back to the group. "Let me go you froggy fuck!" He said as he struggled in the vice-like grip of her tongue. "Students! Stay back!" #13 said as a cap opened on his index finger, a vacuum of gravity and air awaited the villain as he was slowly getting sucked into the void of the hero's quirk. "Not so fast, hero!" Black Mist said as he opened a warp gate directly behind the hero. "#13!" The class simultaneously yelled as the hero was being pulled apart by his own quirk. "S-Stay b-b-back" the hero said as he was slowly being sucked into dust. "Get away from him!/Fuck you!" Todoroki and bakugo said simultaneously as the bi-color-haired teen froze the surrounding temperature to send a glacier crashing on the villain. "Die!!" Bakugo, not being outshined punched his way with his hands propelled by the use of short bursts of explosions. The villain huffed before he sent even more warp gates towards the class of heroes in training. "Why don't all of you take a short break?" He said as he sent the class flying into different zones of the USJ. He looked pleased with his work until he heard a loud metal clang behind him. "Oh No!" He glanced towards the gate, slightly ajar. "Tomura! Someone has escaped!" He yelled towards the man covered in hands. "You dumbass! You had one goddamn job!" He yelled back as he scratched his neck in annoyance. "You see that, eraserhead?! You may have found a cheat, but that doesn't mean we can't have fun now can we?" He said as he crouched down to the beaten and pummeled body of Aizawa. The Villain hummed before he glanced towards the hulking black figure pinning the pro-hero down. "Isn't that right, Noumu?"

"W-Where am I?" Izuku said as he rubbed the throbbing pain in his head away. "We got portalled to some section in the USJ" Kyouka said as she collected herself and brushed off the dust that covered her skirt. "O-Ow" another feminine voice called to the two as they looked, it was Yaoyorozu. "Kids like you should be burning in hell!" A grunt with a knife charged up to them. "Oh no you don't!" Kyouka said as she plugged her earlobe-jack into her boots, the sound of her heartbeat broadcasted and boomed towards the poor sap. The purple-haired girl kicked the body lightly to check if he was safe to stay around. "That's so cool, Kyou-senpi!" Izuku cooed as a light blush graced her face. "We shouldn't rest just yet, we have company" Yaoyorozu said as she pointed to several villains slowly approaching them. "Here" the black-haired girl produced swords and staffs using her quirk. She tossed the katana to Jirou and the staff to Izuku, She herself was brandishing a scimitar. "Get ready!" Kyouka said as she went into a fighting stance and walked backwards to make sure her teammates would cover for her. "Die! Kid!" A woman with knives for fingers leaped at Izuku as he quickly panicked. He was about to hit her with his staff, but the neck of his guitar snagged on Jirou's shoulder. He lost his footing and toppled over, luckily for him. He had enough force and momentum punt into the staff as he accidentally chucked it at the face of the grunt. "GAaah!!" She said as the butt of the staff had hit her square in the eye. "Nice job, Izuku!" Kyouka said as she slashed a grunt away. "I didn't know you were a fighter" Yaoyorozu said before she dodged a kick by a hair, then she punched the grunt hard enough for him to be rendered unconscious. "Th-Thanks" Izuku said as he scurried to get his staff back. "Do these guys ever get tired!?" Jirou said after she scored her 5th kill, Izuku on the other hand had accidentally totaled 8 kills. All of which have happened on total coincidence and him being clumsy.

"-I am here!!" A booming voice came from the gate as the three shifted their focus towards allmight entering without his usual smile, this time he wore an uncharacteristically serious scowl. "I had a gut feeling that something might go wrong, And Tenya just proved my suspicions" He said as he stepped down the stairs. "Ahh! Finally!" Tomura said with glee and animosity laced in every word. "Noumu!" He called out to have the hulking figure pinning Aizawa shift it's attention. "Your toy has arrived" He said before the expose-brained freak tossed eraserhead aside to focus on the top hero ahead. "GO KILL!!" Shigaraki yelled as Noumu launched himself towards allmight, with almost impossible speeds the two were trading punches with each other. Large bursts of wind were blowing with every punch landed, small craters formed form the sheer force behind he collision of fists colliding with bodies. "I-It can keep up with allmight" Izuku said as a nervous sweat dropped from the side. "It's even with ALLMIGHT!?" He asked before he thought of a plan. "Goddamnit! izuku Think!" He yelled in frustration as he tugged locks of stray green hair. "Take it easy Izuku, Allmight's got it" Kyouka said as he patted the boys back. He processed the scene, "C'mon! Find. A. Weakness!" He said as he glanced the hulking figure taking its stand and working its way to weakening allmight down. "W-Wait" Izuku furrowed his brow as he saw one saving grace, the big bastard's brain was encased in glass. "That's It!!" He exclaimed as he rushed over to the scene.

"Oi! Where do you think you're going!?" Jirou said as he gripped his collar to stop the boy from doing anything stupid. "I need to help allmight!" Izuku said with conviction and flames in his eyes. "And how the hell are you going to do that!?" She said as the boy still had that altruistic flame in his gaze. "S-Somehow" He pointed towards the noumu battling allmight, the boom of every punch and hit was heard throughout the USJ. "I need to damage his brain, somehow" He muttered as he looked down, he focused and pondered on how the hell he could actually damage the beast. Melee was definitely out of the question, he didn't have anything ranged or remotely usable at hand. "We can help if you need us" Yaoyorozu said as she walked up to the two. "You're not supposed to encourage him" Jirou said as the boy muttered on. He looked towards his feet, his thoughts brought him to possible uses for waves or projectiles to be used. Izuku looked down until he glanced on Jirou's boots, Subwoofers boosted with tech from the support department has definetly caught his eye. "Maybee" he muttered before he shot up and confronted the purple-haired girl in front of him. "What's your foot-size!?" Izuku said before the latter gave a strange look. "What!? Why!? You're not supposed to ask these sort of stuff at a time like this!" She said with weird expressions and slight annoyance. "Kyouka" Izuku said sternly "What's your foot size?" He asked in a more serious tone, the purple-haired girl got the message and took him seriously. "Around 6 and a half, why?" She asked in a huff before the boy nodded. "it shouldn't be too tight, then." He said as he took of his shoes. "Wait why!? And what the hell are you gonna do with my boots!?" Jirou said in protest as Izuku asked her for her special boots. "I need to shatter that glass barrier encasing it's brain, and I'm not getting close anytime soon" he said as he quickly glanced towards Allmight and noumu in a stalemate. "I need your boots to amplify the guitar's chords" Izuku said as he removed the glossy green and black guitar that was strapped on his back. "I-I see" She said before she took off her boots and gave it to the boy. "It fits perfectly" he said as he took a few practice steps. "Yao-san" he called to the black-haired teen watching the clash of behemoths before her. "Yeah, Midoriya-san?" She said before the boy gave her a determined look. "Can you make an aux chord? Both ends must be male" he said as the teen gave a nod and used her quirk to produce said item. "Wait Izuku!" Jirou said before the boy could storm off, he glanced behind him showing the two girls looking at him with concern. "Be careful" The purple-haired teen said as Yaoyorozu gave a smile. "I can't promise that" Izuku said as he ran away from the earthquake zone and rushed towards the two lugs in a stalemate.

'Melee probably won't work. So I've got to get behind and surprise that thing.' Izuku thought as he hid in the background watching All Might fight the Nomu. Unnoticed by the villains and him as Izuku crept closer and closer. He tightened the strap to his guitar and plugged in one end of the aux cord in. "Wait! Where would I even plug in the other end!?" Izuku thought as he looked for the aux port in the boots. He heard a loud boom as he saw half the Nomu's body underneath All Might in attempt to do a German Suplex. But failed as the villain Black Mist stepped in. 'Now's my chance!' Izuku rushed in as he attracted attention to the villains and All Might and jumped forward and slid underneath All Might's body. "What the hell is with the guitar kid? Some sort of weapon?" The pale grey haired villain said as he was behind Nomu's head and locked his head around the neck. "Yeah, a weapon. And also the end for you!" Izuku said as he jammed the other end of the aux cord into the Nomu's head. He shattered the glass that was encasing the soft membrane of the behemoth's brain, It shouted in pain as blood and brain juice squirted out before healing back. But the cord still stuck in. "Alright. I hope this works!" Izuku said as he adjusted his legs to the Nomu's head and strummed the cords on his guitar in a hurry. "Gwoooooooaaaaahhhhhh!!!" The Nomu shouted as sound waves were lodged into its brain and hitting the sides of its head. It released All Might and grasped Izuku's leags in prying him off. "I won't let go of you! Sit back and listen to this!" Izuku said as he played random notes sloppily as the Nomu flailed and began punching his legs. Shaking him off. Crashing into lights and trees in hope of Izuku falling. "Nomu! What's wrong with you! Get that brat off and beat All Might!" The grey haired villain shouted as he watched his anti-symbol weapon being beat by a kid with a guitar.

Izuku was still on his neck. He could feel the bruises and pain throughout his body. Getting bruises on his legs, chest, arms. Even his head bleeding and roughed up. But his legs still locked, and his guitar not even damaged. "Ha...ha...g-give up? " His answer was given in the form of two fist punching his sides as he heard crunching sound and coughed up a bit of blood. "Figures, fans will always be wanting more. Haha."
"Midoriya/Deku!" Izuku saw All Might, Todoroki, Kirishima, and Kacchan barley coming and stopped as they saw him hit by the Nomu. "Well I guess this is the last tune I'll play for now. I need more practice and then I'll play you a song...Nomu!"
"Groooooaaaaaahhhhh" The Nomu cried as it jumped and leaned back to have his back facing the floor. "There it is!" Izuku ripped out the amp cord that was lodged in between the noumu's brain to have the amp plugged in the side of kyouka's boots. he positioned his legs to face each other as they caught onto the neck of the beast, he brought his bleeding hands up. "Hear this, a new sound I created called, Black Soul!" Izuku said as he moved his fingers across the cord as his hand shaking up and down. Hitting notes along as they were pushed to the side and Nomu screamed in pain. It's head shaking violently as it held its head in pain and blood spewed from its eyes and mouth. The sonic booms accompanied by strums of notes shattered the remanence of the glass shield that held up it's brain. The surviving grey-matter splurted onto the ground, blood and matter fell as the rapid regeneration stopped, Without the main server the body was useless. All of the quirks it possessed were halted by taking out the brain, but the battle was not without a cost.
Finally, it collapsed.
Unmoving and Izuku falling to the ground. "Shit! Nomu down! And heroes!!! Fall back!" The grey haired villain shouted as the teachers came and the bill retreating. 'Ahh...not bad for playing it for the first time.' Izuku thought as he looked at the guitar in his hands. His vision becoming fuzzy as he saw teachers and Kyouka in his sights. 'Ah! That's right...I forgot I wore her boots. I...probably..messed them up. I...make it up to her....least I know her shoe size...next time...we go out...together...' His eyes grew heavy as Kyouka ran over to him with worry. But his smile ever so peaceful and he fell into unconsciousness.

"IZUKU!!" The purple-haired teen slid down the earthquake zone, to run desperately at the boy. "Goddamnit! I told you to not to do anything stupid!" She yelled in desperation as she saw the boy's unconscious body hit the ground. "G-Get up!" She said as she shook his unmoving body, tears stained her eyes as she saw the the boy garner no reaction. "Jirou-san. We should get him to recovery girl" Allmight said as he walked his injured self to carry the boy. "Let's go! Let's go, Please" She said with clear desperation in her breath as she glanced at the limp boy being carried by allmight.

A/N Anime_MultiPlay_ helped me with the final clash. I suck at action scenes, like hell.
