I, the Heavenly Demon, Have Become a Magical Girl
The moment I opened my eyes, the first thing I saw was a pink ceiling.
…Pink?
I blinked several times, but the color didn’t change. A soft, pastel pink ceiling decorated with cute star and heart patterns filled my vision. It was the kind of room a little girl would beg her parents for.
That wasn’t the only strange thing. My body felt… wrong. Too light. Too small. And there was an unfamiliar weight on my chest.
I slowly raised my hand. A slender, pale wrist. Delicate fingers that looked like they’d never held a sword. This wasn’t my hand. This wasn’t my body.
“What… is this?”
The voice that came out was clear and high-pitched. A girl’s voice. My voice.
I shot upright. The room spun for a moment before I caught my balance. I was sitting on a bed with frilly pink sheets. The walls were covered in pastel wallpaper, and shelves were lined with plush dolls and sparkling trinkets. A full-length mirror stood in the corner.
I staggered toward it, heart pounding.
The girl staring back at me had long silver hair that flowed down to her waist, large violet eyes, and a face so beautiful it looked like it belonged in a painting. She wore a white nightgown with lace trim. She looked about sixteen or seventeen.
I reached out. The girl in the mirror did the same.
“…This can’t be.”
My fingers touched the cold surface. The reflection copied every movement perfectly.
I, the Heavenly Demon, Lee Ji-sang — the man who had unified the martial world, slaughtered countless enemies, and stood at the peak of Murim — had become this delicate girl.
A wave of dizziness hit me. I grabbed the edge of the mirror to steady myself.
“Just what sorcery is this…?”
Memories that didn’t belong to me began flooding in. A normal high school girl. A peaceful life. A contract with a strange creature from another world. The power to transform into a magical girl and fight monsters.
Lee Chae-rin.
That was this body’s name. My new name.
I clenched my small fist. Even though the hand was soft and weak, I could still feel the faint pulse of my internal energy. It was there — my cultivation, my very foundation as the Heavenly Demon. But it was trapped inside this fragile vessel, like a dragon forced into a teacup.
“Hah… hahaha…”
A dry laugh escaped my lips. The sound was far too cute for the situation.
I had died fighting the Eight Great Clans and the righteous factions. I clearly remembered my final moment — the taste of blood in my mouth, the cold blade piercing my heart, the sky splitting apart from my final technique.
And now I had reincarnated as a magical girl?
This had to be some kind of cosmic joke.
Just then, something small and round floated up from the desk. It looked like a plush toy crossed with a floating orb. Two tiny wings flapped as it approached me with sparkling eyes.
“Chae-rin! You’re finally awake! We have to go to school today~”
The creature spoke in a high, sugary voice that made my skin crawl.
I stared at it coldly.
“What are you?”
“Eh? It’s me, Puff! Your partner! Did you hit your head or something?”
It tilted its round body, looking genuinely confused.
More memories surfaced. Puff. A creature from the Magical Realm. It had formed a contract with Lee Chae-rin, granting her the power to become a magical girl.
I narrowed my eyes.
“Contract… Magical girl…”
The words felt ridiculous coming from my mouth. I, who had once commanded the fear of the entire Murim world, was now supposed to prance around in a frilly dress and fight evil with the power of love and friendship?
Absolutely not.
I would rather die again.
But as I thought that, a glowing window suddenly appeared in front of my eyes.
"Contractor: Lee Chae-rin"
"Current Status: Heavenly Demon Soul Integrated"
⟨ SYSTEM INITIALIZATION COMPLETE ⟩
“What the hell is this?”
I swiped at the window, but my hand passed right through it. More text appeared.
The soul of the Heavenly Demon has successfully fused with the body of the magical girl candidate.
Warning: Extreme personality mismatch detected.
Recommendation: Adapt to new circumstances or risk mental collapse.
I stared at the floating text in disbelief.
Adapt? To this?
I, who had cut down thousands with a single swing of my blade, who had made the heavens tremble with my roar — I was supposed to adapt to being a frilly little girl who fought monsters with sparkly magic?
The floating creature — Puff — tilted its head again.
“Chae-rin? Are you okay? Your face looks really scary right now…”
I slowly turned to look at it. My violet eyes gleamed with killing intent that no sixteen-year-old girl should possess.
“Listen well, little floating thing.”
My voice was quiet, but it carried the weight of someone who had once ruled the world through fear alone.
“I don’t know what trick of fate brought me here, but one thing is certain.”
I cracked my knuckles. Even in this small body, the motion felt familiar.
“I will reach the peak once again. Whether through magic, martial arts, or whatever nonsense this world throws at me — I will stand above all.”
Puff’s eyes widened in fear.
“U-um… Chae-rin? You’re being kind of intense for a magical girl…”
I smiled. It was a terrifying smile that didn’t belong on such a lovely face.
“Magical girl, you say?”
I looked back at the mirror. The beautiful silver-haired girl stared back with eyes full of ambition and bloodlust.
“Fine. If that’s what I must become…”
I raised my hand and clenched it into a fist.
“Then I shall become the most terrifying magical girl this world has ever seen.”
Somewhere in the distance, I could almost hear the heavens laughing at me.
But I would make them regret it.
After all, I was still the Heavenly Demon.
Even if I now wore a skirt.
