Hello!! I'm not claiming this as my work. It's AI generated as I have no writing skills. I only draw stuff but I've had an idea for so long but couldn't write it on my own- I'd love to see people taking this idea and using it in their stories :33 I have been playing Zenless Zone Zero and what if there was thirens in the BNHA universe? I made (y/n) have natural abilities and that thirens were rare in this AU. (Y/N) is a bastard child between endeavor and a random strong thiren mother. This story is gender neutral! Anyway heres the summary of this AI generated story>
(Y/N) spent their whole life trying to stay invisible, but when their hidden Quirk erupts at the U.A. Sports Festival, thereās nowhere left to hide. Now suspended and forced into Quirk training under Endeavorās watch, they must finally face the power theyāve feared for so longāor risk losing control forever.
Sport FestivalāA Secret Unleashed
(Y/N) never wanted to stand out. They had spent their entire life hiding, blending into the background, making themselves small. It was easier that way. It was safer.
The moment he touched them, his smug smirk stretching wide as he activated his Quirk, (Y/N) knew something was wrong. He thought he had copied their agility, their precisionāthings everyone assumed were their Quirk. But they werenāt. They were justā¦ them.
What he did copy, thoughā
Brilliant, untamed, and hungry, they erupted from his hands in a violent blue inferno. The heat was suffocating. The air cracked around him. He staggered back, confusion flickering in his wide, terrified eyes before pain overtook him.
The fire consumed his arms instantly. Unlike (Y/N), his body wasnāt immune. His screams echoed through the stadium, raw and agonized, as his own power turned against him.
(Y/N) justā¦ stood there.
Their breath hitched. Their limbs locked. They couldnāt move.
The crowd wasnāt cheering. They were silent. Stunned. Horrified.
Monoma collapsed to his knees, desperately trying to put out the flames, but they wouldnāt stop. The smell of burning flesh curled in the air, sharp and nauseating, and something in (Y/N)ās stomach twisted so violently they thought they might be sick.
Not by skill. Not by strategy. But by accident.
Their secretāthe thing they had buried, ignored, refused to acknowledgeāwas out.
The realization hit them in waves, slamming into their chest over and over. They barely heard Present Micās panicked shouting, barely saw the pro heroes rushing in, barely noticed the way the entire stadium was now staring at them.
He was standing, hands clenched into fists at his sides, eyes locked onto them with an expression they had never seen before. Shock. Realization. Something elseāsomething unreadable.
Because that fire wasnāt just fire. It was his. Stronger. Wilder. Hotter.
(Y/N) swallowed hard, their hands trembling at their sides.
They never wanted this. Never wanted them to see.
Everyone's thoughts regarding this incident>
For the first time in years, he is completely speechless.
Those flamesāhis flamesāwere stronger than his own. That deep blue, raging hotter than anything he could produce, was something he never imagined (Y/N) possessed. And yet, there it was, burning uncontrollably in front of thousands.
He had suspected (Y/N) had a Quirk, but (Y/N) never trained, never showed it. Did (Y/N) know? Did they hide it from him on purpose?
His fists clenched as he stared at (Y/N)ās frozen form. (Y/N) looked horrified by what had happened.
And (Y/N) had just revealed to the world that (Y/N) was more powerful than even him.
Shoto's breath caught in his throat.
For so long, he thought he was the only one left with fire in their bloodline. Toya had been the exception, and he had died for it. But nowā(Y/N).
Had (Y/N) been hiding this? Did (Y/N) know how strong (Y/N) was?
His hands curled into fists. He didnāt know what he was feeling. Resentment? Jealousy? Shock? Or was it something worseāguilt? Had he spent so much time treating (Y/N) like an intruder that he failed to see the burden (Y/N) was carrying?
For the first time, he saw (Y/N) not as an annoyance or a reminder of his fatherābut as something else.
That was all Bakugo could say as he watched Monoma writhe in agony, (Y/N) standing there like a ghost, completely frozen.
This whole time, (Y/N) had been hiding that?
His jaw clenched, his heart pounding. That wasnāt just some weak-ass fire Quirk. That was power. That was destruction.
And the look on (Y/N)ās faceālike (Y/N) was about to be sickā
Why? Why the hell was (Y/N) scared?
Did (Y/N) seriously not know (Y/N) had that kind of firepower? Or did (Y/N) know and choose to hide it?
Either way, Bakugo wasnāt sure what pissed him off more.
Izukuās brain was moving a mile a minute.
(Y/N) had never shown signs of a fire-based Quirk. There had never been any reports of (Y/N) using flames before. And yetāthose werenāt just flames.
They were Endeavorās. Noāstronger than Endeavorās.
His grip tightened on his notebook as he stared at (Y/N), taking in every detailāthe way (Y/N)ās hands shook, the way (Y/N)ās breath came too fast, the way (Y/N)ās face had gone pale as if (Y/N) was the one who had been burned.
(Y/N) hadnāt wanted this. (Y/N) hadnāt wanted any of this.
This wasnāt just a fight. This was something else. Something deep. Something painful.
And Izuku couldnāt help but wonderā Just how much had (Y/N) been hiding?
Aizawaās eyes narrowed.
He had always kept an eye on (Y/N). (Y/N) was quiet, avoided conflict, kept to (Y/N)ās self. He thought he had (Y/N) figured out.
(Y/N) had been hiding somethingāsomething massive.
His hands gripped the capture weapon around his shoulders. The way (Y/N) stood, locked in place, staring at Monomaās burns in horrorā
This wasnāt a student reveling in victory. This was a student on the edge of breaking.
And that made (Y/N) dangerous.
Toshinoriās fingers tightened into his palm as he stared at the scene before him.
(Y/N)ās flames werenāt just powerful. They were devastating.
And (Y/N) was afraid of them.
(Y/N) looked like a child who had just been caught holding a lit match, realizing too late that (Y/N) had set an entire forest ablaze.
How long had (Y/N) been carrying this? How long had (Y/N) been alone in this?
This wasnāt just another revelation of a powerful Quirk. This was a wound. And it had just been exposed for the whole world to see.
Toshinori swallowed hard.
(Y/N) was about to face a storm. And from the look on (Y/N)ās faceā¦
The silence that followed was deafening.
Even as the medics rushed Monoma off the field, the smell of burnt flesh still lingered. The murmurs in the crowd grew louder, voices overlapping with confusion, shock, and something elseāfear.
(Y/N) could feel their eyes on them.
Their hands shook at their sides. Their breath came in short, uneven bursts.
They hadnāt meant for this to happen.
They never meant for this to happen.
Their head snapped toward the pro heroes gathered on the sidelines. Aizawaās gaze was sharp, unreadable. All Might looked tense, his lips pressed into a tight line. Midnight was whispering something to Present Mic, who kept glancing at them like they might explode at any moment.
His eyes were locked onto them, burning just as fiercely as the flames they had unknowingly unleashed. He lookedā¦shocked. Impressed. But alsoāconfused. Like he couldnāt understand how they had made it this far without ever using their flames.
What mattered was that Monoma could have died.
Their stomach twisted, a sickening feeling rising in their throat. They clenched their fists, nails digging into their palms as they forced their voice outābarely above a whisper.
ā(Y/N).ā Aizawaās voice cut through the noise like a blade. Calm. Firm. Unrelenting. āWe need to talk.ā
āI didnāt mean to,ā they blurted, their voice shaking. āI neverā I didnāt know he wouldāā They swallowed hard, their pulse hammering in their ears. āI never wanted this.ā
Their vision blurred at the edges. They needed air. They needed to leave.
They barely heard the shouts behind them as they tore through the hallways, their breath coming in ragged gasps. Their legs moved on instinctāfast, precise, in ways that had nothing to do with a Quirk and everything to do with them.
They didnāt stop until they found themselves outside the stadium, away from the noise, away from the stares.
Back in the stadium, Endeavor stood rigid, still staring at the spot where (Y/N) had been moments ago.
They had never used their flames before.
That much was clear now. The way they reactedāthe horror in their eyes, the way they didnāt even try to control themā(Y/N) had never trained. Never even acknowledged them.
And yet, they had come this far.
Their agility, their precisionāit was natural. Something not even a Quirk. And everyone had mistaken it for one.
He let out a slow exhale, realization hitting him harder than he expected.
They had been holding back this entire time.
Shoto, standing nearby, was equally stunned. He had spent his whole life training, honing his skills, using his Quirk. And yet, (Y/N)āsomeone who had never used their full strengthāhad fought on their level.
Bakugo scoffed, arms crossed. āTch. No wonder theyāre such a pain in the ass.ā
Midoriya, still scribbling furiously in his notebook, muttered under his breath. āHowā¦how is that possible? If Thirens have natural abilities like agility and precision, then that means theyāve been competing with students who use their Quirksāwithout using theirs.ā His eyes darted up, bright with realization. āTheyāve been holding back this entire time.ā
Aizawa sighed, rubbing his temples. āThatās not the issue right now.ā
Because the real problem?
(Y/N) curled into themself, arms wrapped around their knees as they sat in the dimly lit classroom. Their breathing was still uneven, hands trembling slightly from the adrenaline crash.
Not just from the stadium. Not just from the heroes.
The flamesāthose awful, cursed flamesāhad finally revealed themselves, and now, there was nowhere left to hide.
They stiffened instantly, heart lurching, but they didnāt need to look up to know who it was.
His presence was always quiet, yet somehow suffocating when he wanted it to be.
āYouāre coming with me,ā he said, voice unreadable.
āIāā their voice cracked. āI didnāt mean for it to happen.ā
āI know.ā His tone wasnāt cruel, but it wasnāt comforting either. āBut that doesnāt change the fact that it did.ā
They swallowed the lump in their throat. They had no excuses. No arguments.
Slowly, they stood, limbs feeling heavier than ever.
And without another word, they followed him.
The air in the principalās office was suffocating.
(Y/N) sat stiffly in the chair, head bowed, avoiding their eyes. Across from them, the weight of their stares felt unbearable.
Aizawa. Vlad King. All Might. Endeavor.
All of them watching. Judging.
Principal Nezu sat on his desk, tail flicking slightly, but his usual playful demeanor was absent. His small black eyes locked onto (Y/N) with an unsettling sharpness.
āHe could have died.ā
Vladās voice cut through the silence like a blade, sharp and full of barely restrained anger. āDo you even understand that? Monoma could have died because of your flames, (Y/N).ā
āI know,ā they whispered, barely able to keep their voice steady.
āThen why,ā All Mightās voice, calm but firm, filled the room, ādid you never tell anyone about your Quirk?ā
āIāā (Y/N) hesitated. Their fingers dug into their sleeves.
They had a thousand reasons.
They were scared. They didnāt want to be like him. They didnāt want to train, didnāt want to acknowledge that part of themself. They had spent years pretending it didnāt exist, hoping it would just go away.
But none of those excuses mattered now.
They gritted their teeth. āI never wanted to use it.ā
A heavy silence followed.
Endeavor hadnāt spoken once.
āYou went your entire life without using your flames?ā His deep voice was quieter than usual, laced with something (Y/N) didnāt recognize.
They glanced up, just for a second, and saw something in his eyes that made their chest tighten.
For not noticing. For not training them. For not realizing that they had been suppressing something so powerful.
Endeavor had spent years pushing Shoto to use his flames. But with (Y/N), he had done nothing.
And now, they had no control over them at all.
āThat doesnāt change the fact that you kept it hidden,ā Vlad snapped, dragging the conversation back to the real issue. āThat was reckless, (Y/N). If Monomaās injuries had been any worse, weād be dealing with something a lot more serious right now.ā
(Y/N) lowered their gaze again, shame curling in their stomach.
āIām sorry,ā they whispered. āI never meant for this to happen.ā
Nezu finally spoke, his voice eerily calm. āIntentions mean little in situations like this, (Y/N).ā His small hands folded together. āYou may not have meant to harm him, but you did. And more importantly, you put yourself and others at risk by not disclosing the full extent of your abilities.ā
(Y/N) squeezed their eyes shut.
They were in trouble. They knew that.
But worse than the punishment was the weight of everything. The weight of Monomaās screams. The weight of everyone staring at them like they were some kind of monster.
The weight of him looking at them like that.
āEffective immediately,ā Nezu continued, āyou are banned from participating in any more of the Sports Festival. Furthermore, you will be required to undergo supervised Quirk training to ensure this does not happen again.ā
āTraining?ā they repeated weakly.
āYes,ā Aizawa confirmed, arms crossed. āYou clearly donāt have control over your flames, and that makes you dangerousāto yourself and to others.ā
A lump formed in their throat.
They had spent years keeping their distance from their Quirk. They had avoided it for so long.
And now, they were going to force them to face it.
They barely noticed the way Endeavor was still staring at them, his gaze heavy with something he wasnāt saying.
For the first time, he was realizingā
They hadnāt just been avoiding him.
They had been avoiding themself.
The silence in the car was unbearable.
(Y/N) sat in the passenger seat, hands clenched in their lap, staring out the window. The city lights blurred as they passed, but they werenāt really seeing them.
Their mind was still back at the stadium.
Still hearing Monomaās screams.
They swallowed the lump in their throat. How bad were his burns? Would he be okay?
They had been too much of a coward to ask.
Now they were suspended for the rest of the week. Not expelled, not permanently bannedājust suspended. That was their punishment for nearly killing a classmate.
Their fingers dug into their sleeves.
āā¦You havenāt said a word since we left,ā Endeavorās deep voice broke the silence.
(Y/N) stiffened slightly but didnāt look at him.
āā¦Whatās there to say?ā they mumbled.
Another silence. But this one was heavier.
Endeavorās grip on the steering wheel tightened slightly, his expression unreadable. āYouāre not going to ask about your punishment?ā
They shook their head. āAlready know it.ā
Their voice was flat. Emotionless.
But inside? They were crumbling.
Endeavor exhaled through his nose, his jaw clenching. āYou should have told someone.ā
(Y/N) finally turned their head, their gaze dull. āAnd what would you have done?ā
His hands tensed on the wheel. He didnāt answer immediately.
That was what they thought.
(Y/N) turned back to the window. The streets of Musutafu were quiet this late at night, but their thoughts were anything but.
āI never wanted to use them,ā they whispered, barely audible.
Endeavorās fingers flexed, his flames flickering faintly at his wrists before dying out. āI know.ā
They frowned, caught off guard by the quiet way he said it.
For a moment, the tension shifted. Not goneābut different.
Their voice was small, almost fragile.
Endeavor was silent for a beat before answering. āHeās being treated. The burns were serious but not fatal. Recovery Girl is doing everything she can.ā
Their grip on their sleeves tightened.
Their throat burned, but they didnāt cry. They just nodded stiffly, eyes glued to the window.
This one lasted the rest of the ride home.
