A tall man with tanned skin stepped out of the chamber.
Long black hair cascaded down his back, still damp with sweat, and two polished onyx horns curved from his temples like a crown. He was naked, unashamed, a silken cloth barely hanging from his waist as if modesty itself had surrendered in his presence.
"Ah…" he exhaled, satisfied.
"Nara is just as delicious as I imagined… the wives of gods truly are different."
The air screamed.
"VAEL NOCTIS!"
Thunder descended.
The world shattered as a colossal bolt slammed into the mansion, obliterating walls, pillars, and marble alike. Stone and splinters were erased in an instant, leaving only the bed untouched—where a woman still slept, unaware, wrapped in divine exhaustion.
Vael Noctis turned lazily.
"Gramm…" he chuckled, golden eyes glinting with amusement. "What's the matter? Why are you so angry?"
The thunderlight condensed.
An entity made entirely of lightning emerged, divine pressure crushing the land beneath it. The sky howled in rage.
"You bastard!" Gramm roared. "You dare defile what is mine?!"
Vael sighed and raised a single hand. A soft pink glow spread across his fingers.
"Calm yourself."
"Bind."
Chains of lust-tinted energy erupted into existence, wrapping around the lightning god's form, sealing and constricting.
"Caught you," Vael said, smiling in satisfaction.
Then—
Pain.
Vael's expression froze.
He looked down.
A spear of thunder pierced straight through his chest, passing cleanly through his heart.
"What…?" he muttered.
His legs gave out. His body collapsed to the ruined ground.
The chains dissolved like paper thrown into fire.
Gramm stepped forward, divine fury crackling violently around him.
"You thought you could rival a god just because you stood above mortals?" he spat. "Insolent worm."
Vael tried to move.
No mana answered him.
"Die."
The sky itself answered the command.
A pillar of divine lightning descended, swallowing Vael Noctis whole.
There was no scream.
Only dust.
...
"Where… is this place?"
Vael opened his eyes.
A room. Rows of desks. Voices. Noise.
Students.
Humans?
No—something else.
One had hair like stone. Another's neck stretched unnaturally. Others bore horns, scales, glowing eyes. Crude mutations masquerading as evolution.
Vael turned his head slowly, eyes narrowing.
"What… are those inefficient magical iron chariots?" he thought as he glanced outside the window. "They're hideous—"
Agony exploded inside his skull.
His vision shattered.
Memories flooded him.
A child crying.
A notebook filled with scribbles.
Heroes. Quirks. Society.
All Might.
"This world… isn't mine."
Realization struck like a blade.
"My soul…" Vael realized. "It crossed dimensions."
Just before his body had been annihilated, he had activated his final safeguard.
Abyssal Magic: Soul Exile.
A forbidden spell meant to cast his essence beyond divine reach.
"Perhaps Gramm's final thunder tore space itself," Vael thought grimly. "And my soul slipped through the crack…"
He exhaled slowly.
So this was the price.
He—Vael Noctis, one of the Seven Demon Kings.
The Demon King of Lust.
An Eleventh Circle Magician.
A demi-god who shattered the boundary between mortals and divinity—
Reduced to this. He had lost like an ant before a true god's power.
"Midoriya. Midoriya!"
A sharp voice snapped him back to the present.
Vael blinked.
Midoriya Izuku.
That was the name of this body.
"I've called you several times," the teacher said sternly, though his tone softened slightly. "Come solve the problem."
Vael stood and walked to the board.
Algebra.
Primitive.
A classmate snorted.
"Hey, quirkless," a boy sneered. "The only thing you're good at is math. What, even that's too hard now?"
Vael turned his head.
Just slightly.
The boy froze.
A chill ran down his spine—pure instinct, primal fear. He swallowed and said nothing more.
This body is pathetic, Vael thought. No mana. And he doesn't even have this world's power, a Quirk.
Then he smiled.
But as thanks for your vessel, Midoriya Izuku… I will make you the strongest.
He picked up the chalk.
Numbers flowed effortlessly. Symbols aligned. Logic bent into elegant structures far more complex than anything this world could comprehend.
This type of formula was what a 1st Circle Mage would use for their spells.
In less than two minutes, the problem was complete.
Silence filled the room.
Wide eyes. Open mouths.
He set the chalk down and returned to his seat without a word.
Vael Noctis closed his eyes.
A quirkless body.
A world without magic.
And yet…
"…How interesting," he murmured.
...
School ended under a dull afternoon sky.
Students poured out of the building in noisy clusters when a sharp, familiar voice cut through the crowd.
"Hey, Deku!"
Midoriya stopped.
He recognized that voice instantly.
Bakugo Katsuki.
Midoriya—Vael—turned slowly.
So this was the boy who had tormented the original owner of this body for years. The one Midoriya Izuku had foolishly called a friend just because they hang out when they were little kids.
How naive, Vael thought.
He faced Bakugo fully.
"What do you want?" he asked, flatly.
Bakugo blinked.
For a split second, confusion flashed across his face—then irritation exploded.
"Ah?!" Bakugo barked. "Is that how you talk to me now, Deku?!"
Without hesitation, Bakugo threw a punch.
Midoriya didn't dodge.
Didn't flinch.
Didn't even blink.
The fist stopped inches from his face.
Bakugo froze.
His muscles screamed at him to pull back. Every instinct he had was shrieking danger.
Move.
Now.
"You…" Bakugo muttered, eyes wide. "What the hell…?"
Midoriya looked at the suspended fist calmly.
Bakugo yanked his hand back as if burned.
"Thanks," Midoriya said casually.
Then he walked past him.
Bakugo stared at his own trembling hand.
"…What the hell just happened?" he whispered.
...
Midoriya arrived home shortly after.
The door slid open.
"Welcome back, sweetie!"
Inko Midoriya greeted him from the kitchen.
Vael's eyes immediately settled on her.
She was shorter than him, with soft facial features and kind, round eyes. She was slim, her body neatly shaped from years of careful dieting and exercise. Her waist was defined, her posture confident, her movements light. She wore a simple pink blouse and some jeans.

Hm… Vael noted. Not bad... did Midoriya take mostly from his father?
"How was your day?" Inko asked warmly.
"Good," Midoriya replied. "I'm going to my room."
He walked past her without hesitation.
Inko blinked.
"A-Ah… o-okay," she said, surprised.
She watched him go, hands clasped together.
Did something happen at school…? she wondered.
...
The moment the door closed, Midoriya sat cross-legged on his bed.
His expression hardened.
He reached inward.
Searching.
Feeling.
Nothing responded.
"…Tch."
He frowned.
"The ambient mana in this world is pitiful," he muttered. "Even if I force circulation… I'd barely reach the 4th Circle within this body's lifespan."
He clicked his tongue.
"Is there truly no other way—"
He paused.
Something else stirred.
A faint structure buried deep within the body.
"…This is," he murmured slowly, eyes narrowing, "a Quirk Factor."
He examined it more closely.
Fragmented.
Incomplete.
Damaged.
"This body had a Quirk," Vael realized. "It was stolen."
Only traces remained—residual energy, shattered pathways left behind by the thief.
Midoriya smirked.
"Perfect."
He drew out every last drop of mana his soul had retained after crossing dimensions.
It burned.
This was all he had left.
Carefully, precisely, he began weaving.
He connected the broken Quirk fragments, threading them together with lust-infused mana, compensating for what was missing, reshaping what once was into something entirely new.
Not restoring.
Replacing.
The mana poured in.
The structure stabilized.
The fragments fused.
"…Success."
A pulse ran through his body.
A faint pink glow spread across his skin.
A new Quirk had been born.
Not Midoriya Izuku's.
But Vael Noctis's.
He opened his eyes, lips curling upward.
"I'll call it…" he murmured.
"Sin of Lust."
To be continued...

Hey guys, does it look promising?
