The event takes place 2 to 3 months before all for one and all might fight

Ten years ago
--
Somewhere in Kamino Ward, in Yokohama City, a boy barely ten years old lay in a narrow alley, collapsed in a pool of his own blood.
His name was Michael Blackwood. His father was a foreigner, his mother Japanese.
Michael had been born quirkless—a rarity in a family overflowing with powerful abilities.
His father possessed a quirk that enhanced physical abilities to five times their normal limit, though it consumed a tremendous amount of energy.
His mother had a quirk that allowed her to float and fly up to three feet, requiring very little energy but leaving her sick afterward.
His siblings were even more gifted.
His older brother inherited his father's quirk, but an evolved version—fifteen-fold physical enhancement, though it caused severe sickness.
His older twin sister inherited their mother's quirk, able to float and fly over thirty feet, but at the cost of huge energy drain.
And then there was his twin sister—their parents' perfect hybrid. She inherited both quirks with none of the weaknesses. She could soar endlessly and enhance her physical power fifty-fold, all while consuming barely any energy—though her physical body remained fragile.
And then there was Michael.
The failure.
The disappointment.
The quirkless child born into a bloodline of power.
His siblings despised him for something he had no control over.
Today, his misfortune reached its peak. A villain attacked him, and the hero who was supposed to save him took one look… and decided Michael wasn't worth the effort. The hero chased after the villain, leaving the bleeding boy behind.
And so Michael Blackwood died—
with anger,
with hatred toward his family,
and with regret for never taking revenge.
Or… did he?
--
Suddenly, the dead body of the boy jerked—a violent, unnatural spasm—before his eyes snapped open. But the eyes were no longer the deep yellow that once belonged to Michael Blackwood.
Now, one gleamed an eerie emerald, bright and alive…
…and the other was a void of pitch-black, swallowing light itself.
A foreign soul had forced its way into the corpse, merging with the dying remnants of the original.
Michael had returned.
A translucent blue screen flickered into existence before him, static tearing through its edges like claws scraping glass.

Goodbye, Host.}
The screen shattered into blue shards of light that dissolved into the air like dying fireflies.
Those were the last words he ever heard from his so-called system.
As consciousness settled back into him like a suffocating fog, Michael realized the truth:
He had transmigrated again.
The first time, it was into a world of magic and demons—a place where he clawed his way to the top, slew the Demon King, and believed he finally earned peace.
But the people he bled for—the ones he called family—
stabbed him in the back the moment he was no longer useful.
From that betrayal, he learned a lesson carved into his soul:
Humans are the most disgusting creatures alive.
Now life had thrown him into yet another world.
The world of My Hero Academia.
A world he had only watched up to Season 3 in his previous life.
As the memories aligned and the last haze of resurrection faded, he forced himself upright, taking in the cold alley, the blood-soaked ground, the oppressive darkness pressing around him.
But then—
A shadow stretched across him.
Someone was standing in front of him.
Not just someone.
A presence so overwhelming it suffocated the air itself.
A figure he recognized immediately.
The main villain of My Hero Academia.
All For One.
His mechanical mask gleamed under the dim light.
His aura felt like a hand gripping Michael's throat.
And then, All For One spoke—calm, cultured, and horrifyingly amused.
"Ah… so you woke up, little one."

AFO POV
--
Kyudai Garaki—All For One's loyal mad scientist—had been begging him for more subjects again.
"If possible, quirkless ones," Garaki croaked.
"They handle multiple quirks far better. Their biology is… cooperative."
All For One considered this request in silence. His mind drifted through possibilities, strategies, opportunities.
Then, during one of his quiet walks through the back alleys of the city, he saw it.
A villain cornering a small boy—no more than ten—before dragging him into the shadows. A short struggle, a cry muffled by fear, and then silence.
Moments later, a pro hero sprinted past the alley, chasing the villain without even looking down to notice the boy collapsed on the ground.
Typical.
Heroes only cared when it made them look good.
All For One observed the boy from a distance. The child lay motionless, breathing shallow, his consciousness flickering like a candle on the verge of death.
He turned, ready to leave.
But then—
The boy jerked violently, gasping as his eyes snapped open. One eye glowed an unnatural emerald; the other hardened into pitch-black darkness. His body, broken moments ago, began repairing itself with impossible speed—bone aligning, skin knitting, breath stabilizing.
A regeneration quirk? Or something more?
Interesting.
All For One stepped forward, letting his presence fall over the alley like a heavy shadow.
The boy stiffened, instinctively recoiling from the pressure radiating off him.
All For One's voice was calm, smooth, almost gentle—but carrying a weight that crushed the heart.
"Are you all right, boy?"
His real intention was already decided.
If the boy's power was worth taking, he would claim it.
If the boy proved useful, he would shape him.
If the boy resisted…
Well.
All For One had never been sentimental.

General POV
--
As soon as I heard what All For One asked, the answer slipped out of my mouth before I could think.
"Yes, sir… I'm all right."
A satisfied hum came from the darkness.
"Good. Then tell me, boy… what do you think of the current hero society?"
I knew what he was doing the moment the words left his mouth. Testing me. Probing me. Trying to pull me into his orbit.
And yet… the truth came out anyway.
"This hero society is rotten to the core," I said carefully.
"The title of 'hero' has become nothing more than a job."
AFO leaned forward, the air around him thick with malice.
"Oh? Then what do you think about changing this society… or tearing it apart and rebuilding it from the ashes? Would you do that?"
I hesitated.
Then—
A surge of memories tore through my mind. Memories that weren't mine.
Michael Cross… and Michael Blackwood.
Pain. Abuse. Isolation. A childhood shattered long before it even began.
And in that moment, everything aligned.
Everything made sense.
I lifted my head.
"Yes," I said.
"I will destroy this society… and rebuild it, piece by piece."
All For One's laughter echoed through the chamber—deep, delighted, monstrous.
"Excellent. From now on, call me Sensei."
He paused.
"Now tell me, boy… what is your name?"
I thought for a moment. Let the old identity burn away.
"Michael Hellborn," I said.
He repeated it, intrigued.
"Hellborn… interesting."
His voice lowered.
"Is there something you want from me, Michael?"
"Yes, Sensei. But… who are you really?"
AFO chuckled.
"Have I not introduced myself? Very well. I am All For One, Emperor of the Underworld. My quirk allows me to give and take quirks as I see fit."
I met his gaze.
"Then… I want you to take all the quirks from my family. And give them to me."
AFO's smile widened.
Cold. Endless.
"Fine. I will give them to you."
