Kyoichi Takagi finally defeated the monstrous Demon God. He was so ready to go back home to his own world. But then, the huge explosion from that final battle sent him flying into another weird dimension!
This time, he crashed onto a rooftop right where two legendary warriors, the 'PreCure', were fighting a monster. His cheat powers still worked, which was awesome, but something crazy happened. He'd somehow turned into a fairy-like being, the kind the PreCure use to transform and get stronger!
Thrown Into the World of Pretty Cure - The Twin Light Covenant Ring—Embracing You in the Darkness
The treatment room was silent as death.
Medical equipment lining the walls hummed faintly. The waveform on the heart monitor flickered weakly. The smell of disinfectant and old ink hung stagnant in the air.
On the bed, Nagisa lay sleeping.
Her white combat suit was torn in places, and black crystals covered her exposed skin. From her cheeks to her neck, from her collarbone to her chest—they continued their slow encroachment, like living things. Her lips were pale. Her fingertips had turned purple. Only her faint breathing proved she was still alive.
Kyoichi floated beside her pillow.
His golden light flickered weakly, as if about to go out at any moment. His tiny fists were trembling.
(*Dammit...*)
Only the sound of the heart monitor echoed through the room. Beep... beep...
Then—
*Clack, clack.*
The sound of a cane approached. Turning, he saw an old woman with silver hair standing at the entrance to the treatment room. Beatrice Sinclair. Her golden eyes behind her monocle gazed at Kyoichi, filled with deep sorrow.
" It is time."
In her hands, she held a bundle of aged parchment.
" The Twin Light Covenant Ring—a forbidden art that completely shares the life force, magical power, and memories of the contractor and the fairy. The procedure is written here."
Kyoichi stared at the parchment in silence.
" Do not forget the price. If one of you dies, the other dies as well. Furthermore—to activate the art, your magical power and Nagisa's must be completely fused. To do that, you must become one in every sense. In other words..."
Beatrice paused. Her wrinkled hands gripped her cane tightly.
" Within the mental world, you must share a physical body."
Kyoichi said nothing.
He simply gazed at Nagisa's cold hand.
(*I said I'd protect her.*)
Another scene flashed through his mind.
Blood-soaked ground. A fallen woman—Lilia. His own voice, screaming over and over as he held her hand. Her fingers growing colder. Blood washing away in the rain.
" ...I'll do it."
Kyoichi's voice was low and trembling.
" I never want... to fail to protect someone again."
He took Nagisa's hand. It was cold. But still—a faint warmth remained.
" I will never give up."
Kyoichi's golden light began to shine brighter.
Beatrice nodded quietly.
" ...Then let us begin."
She raised her cane. The tip glowed, and an ancient magical circle of runes materialized throughout the treatment room.
" Nagisa's mental world is a labyrinth of darkness, given form by her loneliness and trauma. There, you will face the darkness in her heart."
Kyoichi nodded.
His vision exploded into white.
————
When he came to, Kyoichi was standing in a dark corridor.
It was long. Endlessly long. The walls were cold concrete, and fluorescent lights flickered ominously. It was a familiar sight. The hallways of Gyoukou Academy. But—the air was heavy. Suffocating.
(*So this is... inside Nagisa's heart.*)
Kyoichi was no longer in his fairy form. He was back in his original human body—black hair, slightly long in a short cut, deep brown eyes, a physique of 175 centimeters. Not hunched over, but standing straight.
At the end of the corridor.
A small shadow was crouching.
He approached.
It was—Nagisa as a young child.
She looked about ten years old. Her bright brown hair was disheveled, and she sat hugging her knees, her face buried against them. Her small shoulders were trembling.
" ...Because of me, everyone ends up in danger."
The girl murmured the words repeatedly.
" I'm enough on my own. I'll do everything myself. So—"
Kyoichi tried to step closer.
In that instant—
*THUMP.*
A wall of black shadow rose up between them. Nagisa's heart's defense instinct. A barrier made of darkness, rejecting anyone who tried to reach her.
" Nagisa!"
Kyoichi shouted.
He punched the wall. His fist struck the black haze, but it didn't budge.
Then—
Another scene flickered at the edge of his vision.
A rainy night.
A transformed Nagisa fighting Cipher. Light Purification Fists exploded, and Guroamu shattered. But—blood was streaming from her arm. She was battered. Alone. No one was there. No help was coming.
The image switched.
A classroom.
Lunch break. Amidst the flying laughter, Nagisa sat alone by the window, reading a book. She wore a smile. But—her eyes were dead. Her heart was being crushed, yet she couldn't tell anyone.
It switched again.
Male students surrounded Nagisa.
"Pretty Cure is for girls only, right?"
"Why can a guy like you become one?"
"You're disgusting."
Nagisa was silent. She bit her lip and said nothing.
(*...So this is what she's been fighting.*)
Kyoichi clenched his fist.
" Don't screw with me!!"
He punched the wall again.
" Show me... show me all of your pain!"
And then—Kyoichi released his own memories.
————
The scene shifted.
Another world.
Blood-soaked ground. Lilia, fallen.
Rain was falling. The cold rain soaked her red hair.
"Lilia... Lilia!!"
Kyoichi held her hand. Her fingers were growing colder. Colder and colder. The warmth was fading.
"No... no!!"
The tears wouldn't stop. No matter how much he screamed, she wouldn't open her eyes.
He hadn't been able to shield her from the Demon God's attack. It was his fault. Because of him—she was...
"I... I..."
Clutching Lilia's hand, Kyoichi cried out. The rain washed everything away. The blood, the tears, the warmth.
————
In the dark corridor of reality.
Tears streamed down Kyoichi's face.
" I'm the same... I couldn't protect someone precious to me."
The young Nagisa raised her head.
" But because you were there... I felt like I could fight for someone again."
Kyoichi shouted.
" You're not alone!! I'm here!!"
At that moment—
*CRACK.*
A fissure ran through the wall of black shadow.
The crack spread, and light poured through.
The young Nagisa stood up.
" ...Kyoichi?"
Her form grew before his eyes. She returned to her original age—Nagisa at sixteen. Bright brown semi-long hair, tied in a side tail. Large, strong-willed blue eyes.
The wall crumbled with a crash.
The two faced each other at the center of the dark labyrinth.
" ...You came."
Tears spilled from Nagisa's eyes.
" Of course I did. Idiot."
Kyoichi walked towards her.
————
In that instant, Beatrice's words echoed in his mind.
*'Within the mental world, you must share a physical body.'*
Kyoichi embraced Nagisa.
" Tell me if you're scared."
Nagisa shook her head.
" I'm not scared. If it's with you, Kyoichi... I'm not scared."
She wrapped her arms around his neck herself.
In that moment—
Their bodies began to glow. Their clothes dissolved into particles and vanished.
The two held each other, naked.
Kyoichi's hand traced along Nagisa's back. With every touch, their magical power resonated, scattering golden sparks. Crackling, like tiny bolts of lightning.
" What is this...?"
Though bewildered, Nagisa felt a sense of relief she had never known in Kyoichi's warmth. She buried her face against his chest. It was warm. She could feel his heartbeat.
"This is... the Twin Light Covenant Ring's..."
Kyoichi's hand slid from Nagisa's back down to her waist. Her skin was astonishingly smooth, and a sweet numbness ran through him with every touch.
" Ah..."
A small sound escaped Nagisa's lips.
Kyoichi's magical power and Nagisa's magical power had begun to resonate. His crimson magic and her light magic intertwined in a spiral. The entire mental world began to glow like an aurora.
Kyoichi laid Nagisa down.
The floor of the dark labyrinth had, at some point, transformed into a soft carpet of light.
His fingers traced along Nagisa's chest. From the hollow of her collarbone to the swell of her breasts. Carefully, as if touching something fragile.
" Nn... that spot's sensitive..."
Nagisa's body jerked. Her breasts were small, yet beautifully shaped. Kyoichi's hand gently cupped one.
" Aah... your hands are so hot, Kyoichi..."
Kyoichi continued touching her skin in silence. Magical power flowed from his fingertips. Inside Nagisa's body, light and darkness mingled.
Nagisa's hands hesitantly wrapped around Kyoichi's back.
" I want... to touch you too."
Her fingers traced the muscles of his back. A rugged texture. When she touched an old scar on his neck, Kyoichi trembled slightly.
" Did it hurt... here?"
" ...It's an old wound."
Tears welling in her eyes, Nagisa pressed her lips to the scar.
Kyoichi's fingers parted Nagisa's thighs.
Her hidden place was revealed. Beneath the faint tuft of hair, nectar was already seeping out.
" No... it's embarrassing."
" Do you hate it?"
" ...I don't hate it. I want you to see me, Kyoichi."
She spread her legs of her own accord.
" I want you... to know everything about me. I want to feel you inside me."
Kyoichi nodded.
Slowly, he positioned himself over her.
The tip touched her wet entrance.
" I'm going in."
" ...Come. Inside me."
*Squelch.*
Kyoichi entered Nagisa. Slowly, as if confirming every sensation.
" Aaaah...!!"
The moment of penetration, their magical power fused explosively. Nagisa's two years of loneliness, Kyoichi's pain of loss—all of it was shared in an instant.
Tears overflowed.
But—they weren't tears of despair.
They were tears of forgiveness and acceptance.
Kyoichi began to move his hips. Slowly, but surely. Every time his penis rubbed against her vaginal walls, Nagisa's body arched backwards.
" Ah, aah... Kyoichi, Kyoichi...!"
Nagisa kept calling Kyoichi's name. Her moans echoed through the mental world.
Inside, she was astonishingly hot, and her tightness wouldn't let Kyoichi go. The slick, fleshy walls clung to his penis. With every piston-like movement, obscene, squelching sounds filled the air.
" More... deeper...!"
Nagisa wrapped her legs around Kyoichi's waist. Her heels pulled his hips closer.
Kyoichi held her waist and thrust deep inside her all at once.
" Hyaa!? There, no... you're hitting deep...!"
Nagisa's pussy tightened hard. It swallowed Kyoichi's penis to the base and refused to let go.
Kyoichi didn't stop moving, slamming his hips against her. Every time his pubic bone rubbed against her clitoris, Nagisa's body jumped.
" Kyoichi... I'm not alone anymore..."
Crying, Nagisa cried out in the midst of her climax.
" Aah, I'm coming... I'm coming...!!"
Her body convulsed, and her vagina contracted violently.
Kyoichi was at his limit too.
" Me too... Because you're here, I can keep living...!!"
He released his hot semen deep inside her. It pulsed thickly, again and again. The cum struck her cervix, filling Nagisa's insides.
" Ah... you're coming inside me... Kyoichi's, inside me..."
They climaxed simultaneously.
In that instant—
Golden and crimson light fused, shining brightly on their wrists.
The Twin Light Covenant Ring was complete.
What appeared on their wrists were two intertwined rings of light. Gold and crimson spiraled together, shining as if alive.
" ...The Twin Light Bond."
Nagisa murmured.
The mental world began to quietly collapse.
————
The treatment room.
Kyoichi opened his eyes.
He looked at Nagisa lying beside him. The black crystals that had covered her body were completely gone.
And then—her eyes slowly opened.
Blue eyes. A powerful light.
" ...Kyoichi-kun."
Seeing Kyoichi awake and positioned over her, Nagisa blushed, as if under the illusion that what had happened in the mental world had occurred in reality too.
" ...What's with that face?"
She gave an embarrassed laugh.
" Shut up... I was worried about you."
Kyoichi cursed as he wiped away his tears.
The two stared at the Twin Light Bond shining on their wrists, speechless.
At that moment—
The door burst open.
Beatrice rushed in, more flustered than they had ever seen her. She seemed too impatient to even lean on her cane properly.
" This is terrible! Both of you, look at this!"
She hurried to the window and threw open the curtains.
The sky outside—
Was completely shrouded in darkness.
