Chapter 1: The First Chrysalis
Reincarnation was not the blinding flash of light or the serene awakening that the old stories promised. For the man who now called himself Nocturne, it had been a jarring, disorienting plunge into a reality that he had once thought was confined to ink and paper. Waking up in the superhuman society of My Hero Academia was one thing; realizing he possessed a Quirk that felt less like a hero's blessing and more like a comic book villain's ultimate weapon was another entirely.
He sat perched on the rusted edge of a fire escape, the relentless neon glow of Musutafu City bleeding through the evening drizzle. Across the street, a massive holographic billboard projected the booming, triumphant smile of All Might. The Symbol of Peace. A man who bathed in the sun, casting a shadow so large that the rest of the world was forced to live in it.
Nocturne pulled the collar of his long black cloak tighter against the evening chill. Faint, luminescent patterns resembling the wings of a butterfly pulsed sluggishly along the dark fabric, syncing with his heartbeat. He adjusted the silver half-mask that concealed his upper face—a sleek, metallic carapace styled after a moth, complete with multifaceted, butterfly-shaped lenses that hid his eyes. A wide-brimmed hat completed the ensemble, plunging his features into an abyss of shadow.
One year, he thought, opening his gloved palm.
For three hundred and sixty-five days, he had felt the energy pooling deep within his chest, a tight, fluttering pressure that demanded release. Today was his anniversary in this new world. And today, the chrysalis within his soul had finally cracked.
From his palm, a sphere of deep, violet light bloomed. It coalesced, pulling the shadows from the alleyway into itself until it formed the shape of a butterfly. It was ethereally beautiful, its wings shimmering with a dark, mesmerizing cosmic energy. It rested lightly on his fingertip, completely weightless, yet Nocturne could feel the sheer, unadulterated potential vibrating within it.
This was his currency. His weapon. His gift.
He closed his fist, letting the butterfly dissolve into intangible energy that hovered just beneath his skin, ready to be deployed. Now, he needed a host.
Nocturne closed his eyes and activated his passive Quirk: Emotion Sight.
Instantly, a headache flared behind his temples. At this stage of his growth, the ability was raw and unrefined, limited to a strict fifty-meter radius. The world around him faded into a muted gray, replaced by swirling, chaotic nebulas of color that represented human emotion. Below him, the bustling sidewalk was a muddy river of dull yellows (anxiety), spikes of bright green (excitement), and flashes of crimson (irritation).
He swept his gaze across the streets, dismissing the trivial, mundane feelings of the evening commuters. He wasn't looking for ordinary. He was looking for desperation. He was looking for a desire strong enough to forge a new Quirk.
Then, he felt it.
It was a sharp, piercing beacon of pure, agonizing sapphire blue—the color of profound, selfless grief, mixed with the harsh, jagged orange of absolute powerlessness. It came from a narrow, garbage-strewn alleyway forty meters to his left.
Nocturne moved. He didn't fly, nor did he possess super speed, but the shadows were his domain. He leaped across the gap between the buildings, his cloak billowing like a pair of massive wings, and landed silently on the rooftop overlooking the alley.
Below, the scene was a tragically common one in a society obsessed with power hierarchies. Three street-level thugs had cornered a young man. The victim was barely out of his teens, wearing a torn convenience store uniform. He was on his knees, clutching his ribs, coughing violently onto the wet pavement.
"Come on, Akio!" laughed the lead thug, a burly man whose forearms had mutated into jagged cinderblocks. "I thought you said you were gonna call the heroes? Or were you too busy playing a human shield for that stray dog?"
Akio wiped a smear of blood from his mouth. Amazingly, the deep gash on his cheek was already steaming, the flesh knitting itself back together at an unnatural pace. Eternal Vitality, Nocturne realized, watching through his Emotion Sight. Rapid healing. A defensive Quirk with absolutely zero offensive output.
"Leave it alone," Akio rasped, his voice trembling but defiant. "You have my wallet. Just... leave the civilians out of this."
The thug sneered, raising a cinderblock fist. "You heal fast, Akio. Let's see how many times I can break your jaw before it stops being fun."
Through his Emotion Sight, Nocturne felt the raw, unfiltered intensity of Akio's soul. I want to protect them, the boy's inner voice screamed into the aether. I can take the hits, but I can't stop the fists. I'm just a sponge for pain. I want to be a shield. I want the power to protect!
It was perfect. A high-potential host with a pure, unadulterated desire that perfectly aligned with his original Quirk.
As the thug brought his fist down, a sudden, unnatural darkness swallowed the alley. The sparse streetlights flickered and died. The temperature plummeted.
"What the—?" The thug stumbled back, looking around wildly.
A distorted, ethereal whisper echoed off the brick walls, seeming to come from everywhere and nowhere at once. It sounded like two voices speaking in unison—one smooth as silk, the other grinding like tectonic plates.
"You bleed for a world that does not notice your sacrifice," the voice murmured.
From the shadows near the dumpsters, Nocturne stepped forward. His glowing butterfly-wing patterns cut through the gloom, casting a haunting purple illumination across the rain-slicked pavement. The thugs froze, paralyzed by the sheer theatricality and the unknown threat of the masked figure before them.
"Who... who are you?" Akio gasped, clutching his healing ribs.
Nocturne ignored the thugs, locking his hidden gaze entirely on the boy. He raised his hand, and the dark, cosmic butterfly materialized from his palm, fluttering gracefully in the freezing air.
"I am the Winged Sovereign," Nocturne whispered, the butterfly dancing around his fingertips. "I see the depths of your heart, Akio. You possess a boundless vitality, yet you are condemned to act merely as a punching bag. You desire the strength to protect. The power to turn your endless endurance into an impenetrable fortress for others."
"Hey, back off, freak!" the cinderblock thug yelled, though his voice cracked with sudden terror. He lunged at Nocturne, swinging a massive, stony hook.
Nocturne didn't even flinch. With a flick of his wrist, he sent the butterfly darting forward. It bypassed the thug entirely, phasing cleanly through his stony fist, and fluttered directly into Akio's chest, sinking into his heart.
"I accept your desire," Nocturne commanded. "Arise, my Immortal Healer. Let them break upon your Aegis."
Akio gasped, his eyes flying wide as a shockwave of blinding, violet energy erupted from his body. The concussive force of the blast caught the lunging thug mid-air, throwing him backward with the force of a speeding truck. He crashed into his accomplices, sending all three men sprawling into a heap of garbage and shattered brick.
Akio slowly stood up, floating a few inches off the ground. He looked down at his hands. Rippling waves of golden and violet light—the Aegis Pulse—flowed outward from his skin. The streetlights flickered back to life, illuminating the awe and raw power painted across the young man's face.
"What... what is this?" Akio breathed, clenching his fists. He could feel the new power humming perfectly in sync with his rapid healing, an extension of his very soul.
The thugs scrambled to their feet, terrified, and sprinted out of the alleyway without looking back, leaving their victim floating in a halo of newly minted heroism.
Akio turned to thank his mysterious benefactor, but the alley was empty. The dark figure in the moth mask was gone, leaving only the faint, lingering scent of ozone and old dust.
High above, standing on the edge of the nearest skyscraper, Nocturne watched his first champion test his new powers. Deep within Nocturne's chest, a phantom sensation bloomed—a ghostly tether connecting him to Akio. He could feel the faint echoes of Eternal Vitality and Aegis Pulse humming in his own veins, locked away, waiting for the inevitable day Akio would fall in battle and the powers would return to their true master.
Nocturne smiled beneath his silver mask.
The first chrysalis had hatched. The swarm had begun.
