Heart Devil [OP Yandere Schizo Ramble LitRPG XD]

Hazy Mountain Ascension Chambers, Hours earlier.

The room was quiet.

Mist hung in low layers, veiling the carved stone tiles with a dreamlike haze. The natural warmth of the mountain breathing through its veins, and the slow, deliberate beat of a heart preparing to change.

Hannya sat cross-legged at the center of the sanctum, her veil draped across her lap.

Before her stood Baku, arms clasped behind his back, posture straight and unmoved. He looked down at her with the eyes of a teacher, fixed in their demand for understanding.

The stone walls around them were painted in old devil scripts. A thousand warnings, promises, and regrets etched by hands long forgotten. This was not a place of comfort.

It was a place of transformation.

"Are you listening, kid?" Baku asked.

Hannya nodded slowly.

He stood there, his face a mask of stern warning. His silence was its own form of pressure, one that tested how deeply her attention sat.

Then he began.

"Devils are not born as one," he said. "We come into the world fractured. Our body, mind, and soul are not a unified being, but three predators locked in a struggle. Fighting to lead a singular will."

Hannya tilted her head, listening intently, though she'd heard this many times, Baku seemed to be extra serious today, so she just accepted the words again, she wouldn't take a beating if she didn't have to.

"Some devils think the body leads," Baku continued. "Others believe the soul guides the flesh. And fools think their mind is king of the system."

His gaze sharpened.

"They're all wrong."

She remained still, watching him like a student before a sacred blackboard.

"The purpose of evolution is not just power," Baku said. "It is unity."

He began to pace, slow steps echoing through the sanctum.

"The three parts must learn to speak to each other. To share. To collaborate. You're not making one dominate the others."

Hannya's eyes spun lazily as she pondered the Dream Eater's words.

"You're telling me to trust myself."

Baku smirked faintly.

"Exactly."

He moved to stand behind her now, his voice coming from over her shoulder like a ghost of discipline.

"Your body has desires. Your mind has judgment. And your soul carries the echoes of something outside of my current understanding."

At that, Hannya blinked. A spark of something stirred deep within, but she said nothing.

And he didn't elaborate.

"You will descend into yourself, your inner world." Baku continued. "You will hear them argue. You will feel them pull. That is normal. That is expected."

He leaned down slightly, voice lowering.

"And if it becomes too much, if one starts to devour the others, you'll either balance them or you'll shatter."

She showed no reaction.

Only a breath. even and calm.

"Do not forget," Baku said, straightening. "This isn't a rebirth, It is not a cocoon."

He turned back toward the far wall.

"This is surgery, a reconstruction. Done from the inside. While you're awake…"

He hardened his heart and spoke. "...And no one's coming to save you if you fail."

A long silence passed between them.

Then, finally, Hannya spoke.

Her voice was soft. Respectful. But there was a light behind it that hadn't been there before.

"And if I succeed?"

Baku didn't turn.

He raised one hand and gestured toward the sealed stone door ahead of her, the one lined with seven sigils glowing in different colors.

"If you succeed…" he grinned.

"…you'll be one step closer to the monster you were meant to become."

She didn't smile. Not yet.

And she stood.

Baku turned to face her again. His expression had not softened, but there was something knowing behind it.

"You'll be alone in there," he said. "Completely. No demons. No Acolytes... No watchers."

"I understand." she replied simply, her face tranquil.

He stared for a long moment.

Then gave a single nod.

"Then go."

She walked toward the stone door, each step deliberate, her bare feet silent across the tile. The sigils responded to her approach, shifting from faint glow to full radiance.

As the doors slowly opened, Hannya paused in the threshold.

"Gra- Senzei," she said softly, "thank you."

Baku didn't answer, but his back became a little straighter.

She stepped inside.

And the mountain sealed her in.

The stone door sealed behind her with a muffled sigh.

The sanctum was completely still, no eyes, no acolytes, no attendants, no Baku, no Noh. For the first time in months, Hannya was completely alone.

She stood motionless for a moment, gaze cast downward, her veil hanging over her face like the final curtain of a stage play.

Then she exhaled.

And the entire act melted away.

Her shoulders slumped. Her back slouched in relaxation. She pulled the veil off and flung it to the side, flapping it like someone airing out a dress. Her face twisted in giddy relief.

"Lilith's tits, Finally!"

She stretched, arms reaching toward the stone ceiling, letting out a long, dramatic groan. "Being so superior and exceptional at every turn really is a lubless job." the creature grunted as she dropped her arms.

Her voice echoed in the empty chamber.

She let out a giggle. Then another. Then a full, almost feral laugh, sharp and breathy.

"Kikiki! Kikiki! Kikiki!"

She spun in a slow circle, arms spread, looking up toward the bare ceiling with wild, glimmering eyes.

Elegance, check!

Clout, check!

The perfect gift, check!

These are the things that drive a man mad with desire, a lofty woman with status!

A cold handsome will pretend to be unimpressed, disdainful even, if she fluanted to much.

But Hannya knew better, she'd studied this game long ago.

Everyday she had offered him reverent prayer through ritual, praise, affection, even a few hail marys sprinkled in, but sady, her inbox had been dry. Interference, surly. The Abyss area was thick with suppression, she had scouted as close as she could already.

…but what if he was ghosting her?

Sure, she'd been a bit forward in some of her messages, but nothing misandric or offensive.

She shrugged.

Love was war, and to gain a prince, she needed to be a huntress. To hesitate was to lose.

She then grinned, her predatory petals spinning with unmasked intentions.

"Kikiki, that frozen heart will crack eventually." Her grin widened, especially after today!

"Evolution. Finally! It's all coming together!"

She clasped her hands under her chin and practically bounced on her toes.

"And in six months, when I stand before my darling Vainglory with a chest bursting with heavy authority, tight waist of superior discipline, and thighs carved by delegated conquest, he's gonna regret being sealed away for so long!"

She cackled again, tossing her head back with a 'womanly' shriek of glee.

He'll soon realize that no paradise compares to a woman built to rule! But she'd never say that out loud.

She was reformed of course.

"Kikikiki!"

The entire mountain felt so far away now.

No councils. No spies. No acolytes or henchmen. Just her and the story she was writing. A beautiful, twisted fantasy where she and Vainglory would stand at the top, holding the leash of gods and devils alike.

Still giggling, she dropped cross-legged to the center of the room, the last of her mask gone.

Her fingers gently tapped the floor.

"Alright," she whispered. "Let's go meet the rest of me."

She closed her eyes.

And her mind sank.

When her awareness rose again, the world had changed.

No longer the sanctum, but a valley under eternal twilight, where a thin breeze carried the scent of fresh blood and wilting roses.

Black petals fell from the sky like snow.

She stood in the middle of a vast, living maze, black-stemmed roses growing out in spirals, their thorns sharp as needles, their blossoms full and velvety. Everything shimmered with a kind of predatory beauty, as if the land itself encompassed Hanny's true nature.

She walked forward, barefoot on damp grass.

The maze guided her without words. The thorns bent around her. The roses swayed with breathless anticipation. As she neared the center, a shape began to emerge through the falling petals.

A pillar.

Massive, towering.

It jutted from the ground in front of a fractured temple built into a sloping hill, cracked columns, sunken steps, and a roof split by time and tension.

If you discover this tale on Amazon, be aware that it has been stolen. Please report the violation.

But the pillar was untouched.

It pulsed with unseen gravity.

Carved across every inch of it was scripture, etched in flowing red lines she could not read. Words of her own will, made at a time when she had no thoughts, only fury. Surrounded by desperation yet appeased with singular affection.

She knew what it was.

Her Tenet.

Its name fluttered in her chest like a shiver.

Desperate Love.

A paradoxical tenet. Two-scripture formation. Forged the night she judged the unworthy surrounding Baku.

She reached out toward the pillar, but the second her fingers touched it… the air shifted.

The roses around her rippled.

And the temple door opened.

She stepped through into the inner sanctum of herself.

Inside, the temple was low and open-roofed, stone overgrown with black moss and roses that curled between the cracks.

At its center were three thrones, chipped, mismatched, and ancient looking. One of them was empty.

The other two were already occupied.

To her right, lounging with one leg draped over an armrest, was her 'Body'.

She looked like Hannya, but rawer. Wilder. Her skin glistened with light sweat. Her eyes were half-lidded, and her mouth curled in something between a sneer and a challenge.

She wore leather armor, crudely stitched from the hide of dread spiders, armor shaped more for intimidation than function. A golden-back spider skin ran along one shoulder, a remnant of the arrogant spider she'd once flayed alive.

Sir Haughty, The Enduring.

Body smirked and cracked her knuckles.

"Well, well, well," she purred. "The brain finally shows up. Took your time, slave driver."

To her left sat 'Soul'.

She was motionless. Regal. Still.

Her long veil shimmered softly over a black robe that shifted like liquid shadow. Her pale pink eyes were haunting, filled with spirals. Constantly turning, inward and outward, as if she stared into an abyss and the abyss answered.

She said nothing.

But her presence crawled across Hannya's skin like silk soaked in honey and cold.

Hannya stepped toward them, her breathing steady.

No mask this time.

She was not here to command.

She was here to unite.

"I'm the mind," she said aloud. "And you are the rest of me."

The Body snorted, in a strange, acknowledging way.

The Soul lifted her head, and nodded slightly.

She walked to her own seat and sat down.

The temple's walls pulsed faintly with breathless silence.

Hannya sat in the center. To her left, Soul, graceful, veiled, and still. To her right, Body, grinning and legs wide, one draped across the arm of her seat, swinging.

"You're slower than I expected," Body said, starting to pace. "After all that buildup, all that 'high born devil' pomp shit, I thought you'd be barking orders by now."

"I don't need to bark," Hannya said. "I listen first. Then I pull the leash."

Body waved her hand. "Shut the fuck up with all that, Noh's not here. You sound like a total clamp." She then grinned. "And you think you're really holding the leash here?"

Soul tilted her head slightly, spirals rotating in her pale pink eyes.

"I remember," Hannya said. "That time… six months ago. Right before I got out of Neel."

That made Body stop kicking her leg. She turned her head.

"A-ah, You mean-"

"Yes. After I crushed Abigail and that dumb elf slut." Hannya said it with venomous fondness, the words sliding out like thorns wrapped in silk. "Their screams were pretty satisfying. Beating up lower species women felt like a long lost hobby."

She leaned back, resting her chin in one hand.

"But then came Arden."

Her voice dropped, and her finger tapped her chin with a tactics grace.

"He was stronger than them, far beyond. We read the whole story, remember? He cuts demons in half without blinking. And I was still new. No real dream body control, no martial might. Just instincts and charm."

Her fingers tensed.

"So I retreated. I found the summoning circle Corrine had laid for me. I knew I only had seconds before he'd spot me with that construct summon. But just as I stepped toward escape…"

Her eyes narrowed on Body.

"…you showed me him."

Body didn't respond right away.

But the air grew hotter around her.

"A golden silhouette," Hannya said quietly. "Majestic light. That voice I imagined all those lonely nights."

Her face darkened.

"I almost turned back. Almost threw everything away to try to impress him."

Soul's spirals also darkened, the pink glow flickering as though doused in cold water.

"But I didn't," Hannya said, leaning closer to Body now. "Because it didn't feel like him. It was beautiful, yes. Perfect, yes. But it didn't see me."

Her smile was small and sharp.

"He would have seen me."

Body scoffed and turned away, arms crossed. "Fine. It didn't work. Big deal."

"Oh, it was a big deal," Hannya said, letting a bit of venom slip through. "Because you almost got us killed. And worse, you tried to use him to do it."

Body tensed, as if finally realizing the biggest issue.

And then, she pointed at Soul.

"She gave me the idea."

Soul blinked.

Hannya turned to her.

Soul remained still for a long moment, then gave the smallest nod.

"I did." she admitted. Her voice was quiet, barely more than a whisper.

"I suggested the idea, a way for Body to express herself. I thought if she helped show what you truly desired, it would help us grow."

Body's smile returned. "And she abandoned me the second it failed."

Soul tilted her head. "You were only supposed to use it once, also… I realized something."

She turned toward Hannya now, robes like ink trailing down her throne.

"You knew it wasn't him. You rejected the delusion. And that means… you're capable of choosing what's real over what's beautiful."

Hannya met her gaze, two sets of spiral-filled eyes staring at one another. The words felt…familiar.

"That's why I sided with you," Soul said softly. "Because the moment you turned away from the golden lie, you became complete. You understand what you want, what we all want. Something real."

Body growled, fangs flashing.

"You're both forgetting something," she said, stamping her foot. "If it wasn't for me, we wouldn't have survived those first months. I bled for us. I ran on fury and a dream while the Mind played pretend and the Soul whispered nonsense, like always." she snorted.

"And now you're invited to sit," Hannya said, voice level. "Not command."

"You don't command me either." she snarled.

"No." Hannya agreed, crossing one leg and placing her hands on the arms of the center throne.

"I lead us. And you follow, maniac. You follow because when the three of us walk together, there's nothing in Hellnia, or the rest of Neel, that can stop us."

Body hesitated, then looked away with a grunt.

"Fine," she muttered. "But don't forget, when you fall again, it'll be me crawling through the mud to get us up."

"I know," Hannya said, smiling to her. "That's why I want you near."

The wind inside the temple quieted.

Roses bent toward the throne of the Mind, their black petals fluttering like eyelids closing in reverence.

Hannya sat still, high on her seat, eyes half-lidded, as she breathed peacefully. A small shift in the air occurred.

Soul sat to her left.

Body to her right.

For a long moment, nothing passed between them but a charged, wordless understanding.

Then Hannya turned her head slightly.

Her gaze fell on Soul.

"You're hiding something from me," she said, voice smooth and calm, but laced with precision.

Soul paused for a moment, she then bowed her head slightly. "Yes."

Hannya's eyes narrowed. "What is it?"

Soul's spiraling pupils rotated slowly. The light in her irises shimmered like old film.

"I'm protecting something." she answered.

That alone was a confession.

The air felt tighter around them.

Black petals paused midair, hovering.

Hannya leaned forward on the throne, elbows on knees. "Is it about the curse in my system?"

Soul said nothing.

But Soul's silence curved like a nod.

The curse had always been there. In her interface. Unnamed. Unmovable. Filled with question marks.

Even the system wouldn't describe it.

"It's tied to something I've forgotten," Hannya said slowly. "From a different life."

Still, Soul said nothing aloud.

But Hannya understood.

The past.

The truth.

Her name wasn't always Hannya.

She wasn't always a devil.

And the demon before had experienced something.

Causing her to become fractured.

And Soul carried the pieces.

Hannya exhaled slowly. She'd sensed it a few times after her rebirth, a tug at her more clear, more superior mind. Gaps in the demon's memories.

"I could force it," she said. "Press you for it. Demand it."

"You could," Soul admitted. "And I would give it to you."

She paused.

"But I don't think you're ready to remember."

Hannya sat there for a moment.

She didn't look upset or argue.

Instead, she tilted her head back, lips curling in a lazy smile.

"You're probably right." she shrugged.

Soul, a little surprised, warned. "Are you sure? You can only retrieve them during evolution."

"Yes, yes. We've got more evolutions down the road anyways." she said simply waving her hand.

Then she leaned forward again.

"Besides, we've got more important things to do first."

Her fingers tapped on the armrest.

"Like getting our future husband out of the abyss before anyone else tries to take what's mine."

That word echoed in the temple.

Mine.

Body's grin flared like fire catching dry leaves.

"Kikiki! I can't wait to save our hubby, then slam-dance on every altar between here and the Greed border, until Hellnia's gates collapse from the noise."

"...Agreed." Soul said, her expression serene but voice sharp as glass. "He will awaken to a world that remembers what he was."

"And who he belongs to." Hannya added.

All three of them exhaled at once.

A perfect, terrifying accord.

Hannya's gaze returned to Soul.

"I'll trust you, trust us." she said softly. "So keep it sealed. For now."

Soul smiled, a real one, small and bittersweet.

"I'll guard it well."

'Evangelist 9.' she thought.

"And when the time comes," Hannya whispered, "I'll be ready to take it back."

She stood up, lifted both arms, and raised her hands high in the air with total seriousness. Her fingers were spread, palms open to the sky.

"To slam dancing our beloved." she said regally.

Like it was a sacred vow.

Body grinned with feral glee, fangs glinting as she clapped her hand against Hannya's with an audible smack. "To slam dancing!"

Soul followed more slowly, but she reached up and pressed her palm to Hannya's other hand. Soft, graceful, but trembling slightly.

"To…To slam dancing." she echoed with a subdued and shaky breath.

A faint blush colored her pale cheeks.

But it was her eyes that revealed the truth, spirals tightening inward, a flicker of forbidden curiosity, calculated obsession, and a light that glittered a little too brightly.

She whispered under her breath, almost too quiet to be heard.

"I-I wonder if his body is the same… as we calculated... back when we were still her."

Hannya blinked slowly.

Then all three of them burst into high-pitched, malicious giggles, like schoolgirls plotting a murder.

Petals swirled around them like curtains drawn on a final act.

Outside the temple, the black rose maze shimmered with quiet understanding. The pillar, Desperate Love stood untouched in the distance.

For now, she had evolved in the only way that mattered.

By accepting herself. Flaws, fractures, obsessions and all.

The temple began to tremble.

The petals turned red.

And a notification appeared.

DING
