Work Text:
Izumi was starting to believe that whoever was responsible for security at UA should be fired. In theory right now she would be finishing her Test of Courage alongside Reiko from 1B, instead she was down both of her arms, facing a potential manslaughter charge for beating Muscular into the dirt, and running for her life to save her classmates from what appeared to be the Yakuza.
From the little she was able to glean from the mad serial killer, he was hired on by the Shie Hassaikai, who wanted to make an example of the next generation of heroes, having synthesized a working prototype of a Quirk Erasing Bullet. Muscular said she was on their list, alongside Bakugo, who showed he had no heroic qualities to him on national television, and Todoroki, who was most likely targeted for his connection to Endeavor as a legacy kid.
Izumi knew that she should likely get to safety, as one of the targets, but after dropping Kota off with Eraserhead, she turned heel and ran back to battle. She smirked internally despite the pain fighting against her adrenaline-induced state. She had a secret weapon that she alone had, none of the other students did. Izumi was biologically quirkless, born with redundant pieces of the past, like wisdom teeth, the appendix, and the infamous pinky toe joint. One For All flowed through her veins now, but it was not a seamless part of her DNA. If she had her DNA rewritten for One For All to integrate, the unnecessary parts would have rotten away the first time she was healed by Recovery Girl. They would no longer be part of her genetic structure.
No. One For All was akin to a soul possessing her, she was its vessel, but it was not a part of her. One For All would not be harmed by the Erasing Bullets. She was the one student who could take the brunt of the damage. The girl bit back a wince at imagining what could potentially happen to someone like Tokoyami or Shoji if they were affected in such a way. Dark Shadow was her own person, would she simply die instantaneously? Would his own bird mutations melt away and kill him in their absence? Would Shoji be unable to breathe, and lose usage of his arms? She would not learn this. She would have to be everyone’s hero.
One For All heeded her call as she tore through Moonfish, keeping her legs intact as she stomped his head into the dirt, his teeth shattering on the hard rocky terrain. She had luckily been able to convince Tsuyu, Shoji and Tokoyami to return to their lodgings when she reunited with them alongside Ochako, Todoroki and Bakugo, she did not know the extent of the quirk erasing bullet’s potential, but she would not risk those with different anatomy to her own. It was not worth the risk. Unfortunately Ochako and Izumi were soon left alone, as a masked magician had stolen away Bakugo and Todoroki, right from their grasps.
Izumi asked Ochako to trust in her, and Ochako gave Izumi weightless properties. Izumi launched herself into the air, zooming behind the masked kidnapper. Her legs flickered in a blue aura, forcing her body to move faster and faster, fighting any air resistance that may have been in the way. She landed directly on top of the magician, and stole the trapped and marbled students back.
Or so she had thought, as the remaining yakuza villains began to retreat into dark cloudy portals, like Kurogiri from the USJ, but a deeper black as opposed to his purple, almost like a faded copy. The magician, now dubbed Mr. Compress showed his hand; the real Todoroki and Bakugo were still within his grasp.
Izumi was out of energy, she could not bridge the gap in time. In vain, she moved her broken and shattered arms forward, trying to grasp anything she could of the pair. One For All once more heeded the call, and black fire poured from her fingertips. The blackened tendrils of energy wrapped around Todoroki and Bakugo, and Izumi grit her teeth and PULLED. The pair flew away from the man’s grasp, and Izumi collapsed to the ground, the pain finally catching up to her. She was grabbed in their stead, the villains taking her away, and leaving behind Bakugo and Todoroki.
…
Something was wrong.
The living corpse of the man felt as his hands involuntarily twitched.
Long before he had lost most of his face to a duel with All Might, All For One considered himself a caring family man. He attempted to do everything he could to free his brother from the shackles of oppression as the Age of Quirks dawned. When that endeavor had failed, he spent his life chasing his brother's legacy. Then, he started a family of his own. Zen Shigaraki became Hisashi Midoriya. A normal family man, an immortal man with the bite and breath of a dragon.
When his child was born, he placed a tracking quirk onto them, so that he would know they were safe, even if his past returned to haunt them. His child was born quirkless, as due to having Hisashi as her parent, she was only a second generation born, still unlikely to have a quirk. However, that allowed Hisashi to dote on her even more. Quirkless bodies held the potential for quirks, with none of the restrictions. He had stockpiled more quirks than he’d ever need, especially with so many redundant copies. In addition to their normal birthday gifts, Izumi would be blessed with small, insignificant quirks that those around her would never realize. She’d never be sick, she would heal far faster than normal, her skin was more resistant to blunt trauma and fire. Of course, he could only hide so many of the quirks. As his child wished to become a girl, Hisashi offloaded Transform to her, with the girl awakening in her ideal form overnight. A little miracle that only Izumi and Inko would know of. Especially after the man was sent into a coma due to collateral damage from a villain attack. Of course, the coma was actually caused by All Might decimating his frontal lobe. He felt horrible to leave his family behind.
One day, he hoped to return, but as he awoke, his daughter had been chosen as the next holder of his brother’s quirk. All For One smiled inwardly at the notion, One For All always should have been a family matter after all. Regardless, in this state, he’d have to lie low until he could recover his old identity.
At least that was the plan. But the fact that the tracking quirk went haywire sent All For One into a shock. All For One had implanted that quirk within her so that he could protect her. He saw it as a duty to his family, to protect them when they were in danger. He had failed that duty when he was indisposed.
He would not fail again.
“Doctor. Watch over Tomura in my absence.”
Doctor Garaki turned to the man with a confused expression.
“Master, whatever for?”
“I do not need to explain myself to you. I must attend to a family matter.”
The man slowly rose, in spite of his body’s ceaseless agony. He cracked his neck.
“Master, I recommend that you at least bring your emergency breathing apparatus!”
All For One smiled as he turned to Garaki, a sinister chill befalling the man.
“Oh Doctor, I promise you. This will not even require me to break a sweat.”
All For One grasped his suit jacket in his hand, seamlessly pulling it away from his form, cloaking it for a moment, before he warped into the unknown.
…
Izumi bit harshly into the blanketing material of the torture room she’d been disposed of in. She used her broken arms in spite of the agony to tie knots of bedsheets around the six bullet wounds that had been fired into her body. Overhaul was relentless, he could not accept that Izumi was immune to his plans. Each revolver shot like searing molten metal poured into her body. She did everything she could to stay awake, even if awake was agony. She realized now that she was not the only victim. A small girl named Eri was the source of their bioweapons.
She needed a hero.
She would survive to save Eri.
She would not die here.
Her vision slowly began to fade to black.
Screaming.
There was so much screaming.
However, soon she felt the familiar warmth of being held, just as she had been as a child.
…
All For One levitated above the base of the Shie Hassakai. Normally, he’d enjoyed the contrast of his brutal fighting with his formal attire, but now he stood above the grunts cowering in fear, his muscular body straining against the clean white dress shirt. He hoped that it’d permanently be stained red after today. An empty face smiled down at the fearful men. Then, suddenly, without moving an inch, the man launched down to the earth, leaving a crater in his wake. The aftershock shattered the ground, trapping multiple men in the cracks.
“Ah, Wizard’s Foot is such a fun starter, is it not?”
All the surrounding men did was scream.
“Hm. Poor audience. Ah well- Spirit Sword”
The man fanned his left arm to his side, a blazing purple blade of energy bursting the fabric of his sleeve away. The man moved from his menacing stance into combat as if violence was his very way of life. The blood of countless men stained the earth as he cleaved into them. Of course, he made sure to aim for nothing vital, at least not initially. A clean death was more than the men who harmed his daughter deserved.
“I’ll make you pay for this bastard!”
A giant man came barrelling towards him as he finished his initial slaughter. All For One smiled.
“Ah. Rikiya Katsukame. Quirk: Energy Suck. What a delightful power to add to the hoard. Devil Trigger : Sword Swarm.”
A swarm of glowing blue blades rose behind All For One and flew towards Rikiya, piercing them to the ground. Rikiya cried out in pain as his body began to resemble pasta sauce as opposed to anything human. All For One slowly stalked over to the man, before calling upon Rivet Stab to pierce his brain and acquire his quirk.
“What are you doing here?!”
A scrawny man in a plague doctor’s getup screamed out after witnessing his comrade become swiss cheese. All For One felt compelled to respond.
“I am here to kill you.”
“Must be Shin Nemoto, Quirk : Confession.”
“You’re not worth the effort. Raging Demon.”
Nemoto did not even realize the moment he had died, consciousness simply was snuffed out as All For One dashed past the man and walked away, deeper into the complex.
The fodder was pathetic in his opinion. So many men required nary a single quirk to dispose of like the trash they were. Another bullheaded man, coated in crystals rushed him.
“Yu Hojo, Quirk : Crystallize. How about I show you some real crystalization? X Ray : Deep Freeze.”
As Yu lunged towards All For One, he unleashed a devastating punch to their stomach, ripping out their entrails. The man’s eyes widened in shock and pain. All For One smiled as he froze the entrails into a spear in his grasp, and plunged it directly into the man’s eye socket, killing him instantly.
However, the spear was quickly pulled away, now wielded by a blonde man in a plague mask.
“All of your moves so far have relied on weaponry, how will it feel when it’s turned against you?”
All For One scoffed.
“Oh, Toya Setsuno. Quirk : Larceny. You know, I am something of a thief myself. In fact, they say that I’ve stolen every move I have, like a clone or echo of sorts. But let me tell you, I do not need a weapon to be strong. Warlock Punch.”
A purple haze surrounded All For One’s fist as it found it’s way through Toya’s chest, the purple stained red.
All For One fell to the floor, unable to stand straight. The floor opened up beneath All For One.
“Mimic.”
All For One sighed as Soramitsu Tabe attempted to devour him as Deidoro Sakaki stunned him.
“Well then, I suppose two can play this game. Hex : Devour Hope.”
All For One’s next movement killed Tabe instantaneously, with no mental effort.
“Ah, Hexes can be so unreliable, but when they work, they sure are lovely.”
Deidoro shook in fear as All For One unsteadily approached.
“It will be fast. Possibly painless.”
All For One stabbed into the man’s head, bubbles bursting out from his scalp as his face was blown off.
“You will not continue your rampage any further.”
Two men now stood in All For One’s path to reach Overhaul. Hekiji Tengai put up a Barrier to shield himself alongside Kendo Rappa, who flexed his muscles in preparation.
“Ah Kendo. This is a family matter for me. Your men have stolen my daughter. I’ll have her apologize to Itsuka for making her an orphan here. Waveshine”
All For One dashed into Hekiji’s shield breaking it instantaneously as a blue shield rippled around him, sending the men flying.
“Shoryuken”
A flurry of red flame surrounded All For One as he uppercut the two men in half.
All that stood in his way to finding his daughter now was Overhaul himself. All For One ripped off the reinforced steel door that guarded Overhaul’s office. Chisaki Kai, a normally composed man, appeared to be paralyzed in fear.
“Oh dear. For the leader of the Yakuza I would have expected more bravado. How I wish I could see the despair within you… oh wait.”
All For One’s Rivet Stab pierced the man’s torso as he tried to run away, stealing Overhaul for himself.
“Ah Overhaul, such a wondrous quirk. It alongside your Bullet’s quirks will do well as delightful presents for my daughter. My illness has made me miss far, far too many birthdays.”
Chisaki’s eyes widened as he realized that the girl he had kidnapped had been the Dark Yet Darker’s daughter. He could only wish for a quick death in that moment.
“Of course, she could barely recognize me like this, however, thanks to Overhaul, I can simply remedy that issue now.”
All For One outstretched his hand over Chisaki’s face, painfully ripping away his features. All For One smiled as his eyes returned, his organs repaired, and his likeness of Hisashi Midoriya could be finished. Of course, the pile of parts known as Kai Chisaki was unfortunately still alive after this procedure.
“Oh dear, it seems I am still left to clean up the trash. But this is a message, here and now. Nobody will harm my daughter ever again. Giga Drill Break.”
All For One’s arm transformed into a spiral of pure energy, rotating rapidly, and he plunged it into the remains of Kai Chisaki, turning him into a puree of viscera and gore.
…
Hisashi Midoriya held his daughter close, repairing her wounds as she was cradled in his arms. Her eyes were barely open past a squint.
“D-dad?...”
Kind grey eyes stared down at Izumi, stroking her hair.
“You’re okay my little treasure. Daddy’s here now. You’ll never have to hurt again. You’re so brave.”
Izumi whimpered in pain and coughed.
“T-there’s a girl here. Eri… she’s a victim too… help…”
“Do not worry a moment dear. She will be saved too.”
…
A tired and battered Eraserhead sat beside a bickering All Might and Sir Nighteye as the men attempted to put together a plan to safely rescue their student. It had only been a few short hours since the yakuza’s invasion of their campsite, but they had to jump into work immediately.
“I told you All Might, she’s not the right one, she’s going to lose One For All and we’re all going to be doomed.”
“Mirai, your visions are often correct, but they are short sighted. There is no better holder of One For All than Midoriya.”
“Oh yes, I would certainly agree.”
A chilling voice emanated from the hall outside the meeting room. The men present inside stood ready for combat, as a blood soaked and fully healed All For One stepped into the room, carrying Izumi Midoriya and Eri in his arms.
“I’ve gone ahead and dealt with the issues you’ve been having. Though I will certainly be having words with the school board for endangering my daughter in such a way.”
“Your daughter? There is no way such a heroic and kind soul bears any relation to you!”
All Might yelled, ready to fight All For One then and there, only for All For One to shake his head and deposit Eri and Izumi in the desk chairs of the room.
“Ah yes, even if you believed that, what of my brother Yoichi, who held that power first? One For All and All For One are a family matter Yagi, whether you like it or not.”
Sir Nighteye scowled.
“Of course, I told you this protege was the wrong choice All Might! She is destined to be a villain like her father.”
“Yet whilst you remained her motionless, I was the one to rescue her. Without any of the moral hangups you hero types display. Though knowing you Nighteye, you have no morality to begin with.”
“What did you do?”
All For One smiled as he hugged his daughter.
“I made sure the Shie Hassaikai would never harm my daughter ever again.”
