Chapter 1: The First Chrysalis
The city of Musutafu was a canvas of neon and concrete, painted over by the blinding smiles of false idols.
From my vantage point on the edge of a rain-slicked gargoyle, three stories above the bustling commercial district, the world looked exactly as it had in my previous life—flawed, distracted, and desperately seeking salvation in all the wrong places. Below me, giant holographic billboards projected the grinning visage of All Might, the Symbol of Peace. His booming laugh echoed through the drizzle, promising a safety that was, at best, an illusion.
Society here worshipped the spectacular. If your Quirk could level a city block or conjure explosions, you were destined for greatness. If it was subtle, or if you were utterly Quirkless, you were relegated to the shadows, expected to be a quiet spectator in a world of gods.
But I had always preferred the dark. It was where the real work was done.
I pulled the wide brim of my black hat down, shielding the upper half of my face. My silver half-mask, molded to resemble the sleek, predatory face of a moth, sat cool against my skin. The butterfly-shaped lenses over my eyes whirred faintly, adjusting to the low light. My long, dark cloak billowed in the autumn wind, the faint, bioluminescent purple patterns on its edges pulsing like a heartbeat.
I was not a Pro Hero. I was not a Villain. I was Nocturne. And tonight, I was going to change the rules of the game.
I closed my eyes and breathed in the damp city air, activating my Quirk. Emotion Sight. It was still nascent, a passive ability I had only truly unlocked a few months prior. It was strictly limited to a fifty-meter radius. I couldn't read minds, nor could I see across the city. What I saw were impressions—auras of raw, unadulterated human feeling bleeding through the concrete and rain.
Immediately, the dark world exploded into a muted kaleidoscope. I saw the dull, mustard-yellow thrum of greed from a pickpocket three alleys over. I saw the sharp, jagged crimson flashes of domestic anger from an apartment window across the street. Most of it was the dull, grey static of apathy—people just trying to get through their mundane lives.
I ignored it all. I wasn't looking for anger or greed. I was looking for desperation. I was looking for a very specific, potent flavor of desire.
I brought my gloved hand to my chest. Beneath the fabric of my suit, just over my heart, I could feel it. The culmination of three hundred and sixty-five days of agonizing patience. A singularity of pure, transformative energy. My power was a slow, agonizing cultivation. One year. That was how long it took my soul to forge a single conduit.
I opened my hand, and the darkness pooled in my palm. It spiraled, condensing into a fragile, breathtaking form. A butterfly composed of pure, crackling obsidian energy, its wings outlined in a brilliant, glowing amethyst. It fluttered its wings once, devoid of weight but heavy with destiny.
This was my gift. My curse. The instrument of my sovereignty.
A sudden spike of emotion flared in my peripheral vision, snapping my attention back to the street below.
It was a deep, resonating sapphire blue. The color of profound helplessness, tinged with the bright, agonizing white of selfless desperation. It was coming from a small clinic at the end of the block, where an armored transport truck had just violently careened off the road, smashing through the clinic's glass storefront.
I leapt from the gargoyle, my cloak acting as a makeshift glider, silencing my descent as I landed lightly on a fire escape overlooking the chaotic scene.
Down below, the situation was dire. The crash wasn't an accident. Two men with heavily mutated, reptilian Quirks were prying open the back of the transport, roaring at the terrified guards. But that wasn't what drew my eye.
The structural integrity of the clinic's awning had been compromised by the crash. A massive slab of concrete and rusted steel was groaning, tearing away from the brickwork, suspended directly over a trapped paramedic and a young civilian girl.
The paramedic was a young man, early twenties, with messy brown hair and a uniform stained with dust. According to my intel, this was Akio. A local fixture.
His Quirk was Eternal Vitality. A rare, passive emitter-type that granted him incredibly rapid cellular regeneration and drastically slowed aging. He could survive a bullet to the brain, heal a severed limb in minutes, and outlive everyone he knew. He was, for all intents and purposes, an immortal meat shield.
But immortality was a selfish power.
I watched through my lenses as the concrete slab snapped. Akio didn't run. He didn't hesitate. He threw himself over the little girl, curling his indestructible body into a protective dome over her frail frame.
The slab crashed down. The sound was deafening. Dust plumed into the air, masking the screams of the bystanders.
I focused my Emotion Sight on the rubble. The sapphire blue aura was blinding now. I could feel his thoughts echoing in the frequency of his despair.
I can take this, Akio's aura screamed silently into the void. It won't kill me. It will crush my spine, and it will heal. But she... she's going to die. My body isn't wide enough. My bones aren't strong enough. What good is living forever if I can't save the person right in front of me?! I want the power to protect her! I want to be a shield for others, not just myself!
It was a perfect resonance. A pure, unadulterated desire that perfectly aligned with his inherent nature. High potential. Incredible drive.
Yes, I thought, a cold thrill running down my spine. You are the one.
The Pro Heroes were still minutes away. The reptilian villains were distracted by the loot. The dust cloud provided the perfect cover.
I dropped from the fire escape, landing silently in the thick of the debris. I stepped over shattered glass and twisted metal, arriving beside the massive concrete slab pinning Akio and the girl. Beneath the stone, I could hear Akio grunting in agony, his bones breaking and rapidly snapping back into place, a torturous cycle of useless immortality.
"Do you curse your own survival, Akio?"
My voice was electronically distorted by the moth-mask—a layered, ethereal whisper that seemed to echo from the shadows themselves rather than from my throat.
Beneath the slab, the shifting stopped. "W-Who's there? Help her! Please, I can't hold the weight off her legs!"
"I cannot lift the stone," I lied smoothly, crouching beside the crevice. "But I can give you the power to do it yourself."
I extended my hand. The obsidian and amethyst butterfly rested on my index finger, its wings beating in a hypnotic rhythm.
"The world has given you a shield that only covers your own heart," I whispered into the dark crevice. "It is a cruel irony to be an immortal who is forced to watch mortals bleed. Tell me, Akio. What is your greatest desire?"
"To save her!" he choked out, coughing on the dust. "To protect them! I don't care about myself! I want to protect them!"
"Then accept my gift, and let your desire take form."
I flicked my wrist. The glowing butterfly slipped through the crack in the rubble. It didn't fly like an insect; it drifted like a falling star, phasing effortlessly through the dust and stone until it found Akio's chest.
The moment it made contact, the butterfly dissolved, sinking directly into his heart.
For a heartbeat, there was utter silence. The ambient noise of the city, the sirens in the distance, the roars of the villains—it all seemed to mute.
Then, the world erupted.
A shockwave of blinding, golden-white light exploded from beneath the concrete. It wasn't a destructive force; it was a wave of pure, kinetic revitalization. The massive concrete slab weighing thousands of pounds was blasted upward, shattering into harmless pebbles before it could hit the ground.
I stepped back, shielding my eyes as the golden light coalesced into a fifty-foot translucent dome.
In the center of the crater knelt Akio. He was panting heavily, his eyes glowing with a brilliant, amethyst light that mirrored the wings of my butterfly. The little girl beneath him was staring in awe. The scrapes and bruises on her arms were rapidly knitting themselves together, sealed by the ambient energy rolling off Akio's body.
Aegis Pulse. The name of the power whispered itself into my mind, a sudden download of instinctual knowledge. An area-of-effect healing wave combined with a localized, temporary absolute defense field.
It was a perfect extension. His desire to project his Eternal Vitality outward had manifested beautifully.
The reptilian villains stopped loading their truck, turning to stare at the glowing dome of light in sheer bewilderment. One of them raised a heavy rifle, firing a burst of automatic fire at Akio. The bullets struck the golden dome and flattened instantly, dropping to the pavement like useless pebbles.
Akio looked at his own glowing hands. The despair in his aura had vanished, replaced by a roaring, incandescent white light of pure, unadulterated resolve. He stood up, placing himself between the villains and the civilians. For the first time in his life, he wasn't just a survivor. He was a protector.
I didn't stay to watch the rest of the fight. The screech of tires heralded the arrival of the Pro Heroes—a fiery hero with a flashy entrance who would undoubtedly take the credit for the villains' apprehension.
I grappled away, ascending back into the rainy canopy of Musutafu's rooftops. As I perched on the edge of a water tower, watching the flashing red and blue lights below, I closed my eyes and focused inward.
There it was. A thin, invisible, metaphysical tether connecting my soul to Akio's.
I could feel his new power humming at the end of that line. Aegis Pulse, layered neatly over Eternal Vitality. The moment Akio was rendered unconscious—whether by a villain, exhaustion, or by my own hand—that butterfly would return to me. And when it did, it would carry both of those Quirks back to its master.
My first chess piece was on the board. The sovereign had taken flight.
I smiled beneath my mask, the glowing butterfly lenses narrowing as I looked out over the sprawling city. It would take an entire year to forge my next Chrysalis. I needed to start looking for candidate number two.
