Heart Devil [OP Yandere Schizo Ramble LitRPG XD]

Devils came from mountain passes slick with mist and starless skies. They came wrapped in fine silks and rare cloths, draped in charms, talismans, and bones, pulled in carriages drawn by horned beasts, or drifting on flying chariots. Not the high nobles, not yet, but the second and third sons of falling families, exiles, house agents, fortune seekers, and quiet opportunists came in droves.

The garden outside of Hannya's pavilion had been reshaped with demonic elegance. Red-glass lanterns swayed from the tall trees. A shallow reflecting pool shimmered with black water, and tables made of petrified fiendwood were set with plates of beast meat and ember-fruit.

The air was scented with lotus wine and heavy with illusion magic, just enough to dull aggression, not enough to cloud the senses.

Baku stood at the entrance, silent and commanding, acting as the host.

And in the center of it all sat Hannya, robed in a gown spun from thin dream beasts and haze thread, her pink hair bound up with a crescent-shaped comb. She looked like a noble devil's treasured daughter, until you met her eyes and saw the spinning abyss.

One guest whispered to another: "She devoured a noble. Ate her down to her bones."

"No," the other said. "She turned Suziana into an art piece. That pavilion? It's still painted with her soul."

Each rumor stoked the fire. Hannya said nothing. She didn't need to.

As the feast carried on, laughter mingled with guarded whispers, and deals began forming between bites of cursed flesh and sips of fermented devil wine.

Later that evening, in the shaded back room of the pavilion, Baku entered the inner sanctum carrying a stack of scrolls. Behind him, the Painted Devil, Noh, lounged with her porcelain limbs tucked beneath her, eyes glazed from too much spice wine.

"They're biting," Baku said. "Two dozen minor houses want an audience. Four want alliance negotiations. One, House Scathe, sent a blade wrapped in spider silk. An offer of military aid."

Hannya swirled a goblet of black wine in her palm. "That's just the ripples. The ones we want will wait. Watch. See if we collapse."

"They're wondering if you can keep control," Noh said from her couch. "If you're stable. Or if what happened to Suziana was a one-time madness."

Hannya tilted her head thoughtfully. "Maybe I should indulge them. Unstable is better than weak."

Baku smirked. "Or we keep feeding them illusions of control. Make deals that benefit us more than them."

Hannya tapped her lip with one sharp nail. "Hmm. You're thinking long game."

"Kahuhu, the only game," Baku replied. "We can't win over Hellnia with power alone. But we can become the gate through which all lesser devils must pass."

She nodded. "Then we offer them a ladder and make sure we're standing on the top rung."

There was a knock at the door. A servant stepped in, bowing low. "Apologies, but a representative from the Blight Temple has arrived. She insists on speaking directly with you."

Hannya arched a brow. "Did she bring a gift?"

The servant hesitated. "A still-beating heart in a crystal cage."

She chuckled at the words. Ironic, in more ways than one.

Hannya stood slowly, smiling wide. "Now that's the kind of diplomacy I respect."

She turned to Baku. "Come. Let's see what filth the Blight Temple wants to offer."

As she passed Noh, the Painted Devil chuckled quietly. "Try not to eat this one."

~~~

The envoy from the Blight Temple stood in the courtyard just beyond the pavilion's edge, wrapped in a living veil of moss and white fungal cords that slithered over her frame like snakes. Her face was hidden behind an ivory mask carved with weeping spores, and she held in her hands a crystal cage pulsing with a crimson heart.

It beat once every ten seconds.

Hannya stepped forward gracefully, Baku trailing just behind her. His steps were noiseless, his expression unreadable, but his eyes never left her.

The envoy knelt low. "Lord Baku, Lady Hannya," she said, her voice muffled and wet, "the Blight Temple sends its regards, and a gift, harvested from a dream-taken Warden from our great city of Hollow Root."

Hannya smiled thinly. "A worthy token. I'm surprised that wardens are still remembered in Hellina. I'll savor it later."

The envoy nodded. "Our temple saved his body but not the soul. Lulling virus is indeed a horrifying sickness." She took a furtive glance at Baku. The Envoy felt a difference in the presence of the senile devil, but she left it be for now. "And a warden cannot exist without a judge, my lady. It's a surprise your fortress carries such history books in this day and age."

"This fortress is full of surprises, Envoy."

Baku watched her closely as she moved forward, took the cage, and turned it between her hands as if it were merely a wine goblet. She played the part well, too well for a newborn devil. Her charm laws pulsed subtly beneath her words, not overwhelming, but present. Just enough to put others off balance, to make them hesitate before speaking.

The envoy continued with ceremonial bows and coded offers, asking for trade access to the fissure's dream residue and use of the eastern paths for their plague priests.

Hannya nodded, listened, asked the right questions, bartered a concession, and promised another. She gave nothing away and left the envoy thinking she had gained everything.

When the masked woman departed with a contented bow, Baku remained quiet, walking with Hannya back through the pavilion. The moon peeked over the horizon as the sun dipped low, the sky violet and strange above them, caught in mist.

"You're getting too good at this," Baku finally said, his voice low.

Hannya glanced sideways. "At what? Talking to mushrooms?"

"At talking shit, building alliances," he said. "You move like you've done this before. Like you're reading from a script only you can see."

She gave a lazy smile but didn't answer.

Baku folded his arms as they stepped inside. His eyes lingered on her back for a moment.

'She sees pieces of what's to come.' He thought. 'Her fate mutation must be refined beyond anything I've seen. Far beyond Masters even.'

He recalled how she'd predicted the nobles' ambush, how she had baited them, how she'd wrapped the pavilion in layers of arrays like spider silk. She never looked surprised, only mildly amused when others played directly into her hands.

A case of theft: this story is not rightfully on Amazon; if you spot it, report the violation.

No novice should move like that.

'She's not just clever. She's practiced. Cold. Like she already knows the shape of tomorrow.'

And that unnerved him.

Not because he feared her, but because he feared what this place was becoming. More guests arrived each day. Alliances were forming. Tribute flowed like water.

And he hadn't signed up for any of it.

He only wanted to guard the dream fissure, to keep it from spilling over and swallowing the realm. That had always been enough. Quiet patrols. Silence. dream beasts to study. A duty that didn't involve masks and banquets and politics.

Sure, he could play the game, but only when he had to.

But Hannya was pulling all of Hellnia's eyes to this mountain, like a bonfire in the snow.

'She's going to change this place,' he realized. 'And maybe she'll survive it. Maybe she won't. But none of them will forget her.'

He looked up to find her watching him now, as if she'd caught the edge of his thoughts.

"Worried I'll turn the fissure into a fortress?" she asked softly.

"No," Baku said. "I'm worried you'll turn it into a throne."

She laughed at that, head tilting back. "Don't be silly. I like thrones, but I prefer pavilions here. Easier to redecorate."

Their conversation was interrupted by Noh's sudden appearance, painted face unreadable.

"Guests from the Bone Choir just arrived," she said. "And they're… chanting."

Hannya rolled her eyes. "Of course they are. Come on, Gramps. Let's go be civil."

As she walked ahead, Baku followed, the weight of his thoughts trailing behind like mist.

~~~

The courtyard trembled with the resonance of hollow-boned flutes.

The Bone Choir devils had arrived en masse, eight tall, skeletal figures garbed in robes stitched from funeral gowns. Each bore a flute carved from the femur of a demonic beast, and each one chanted a different verse of their request. The overlapping tones were enough to make most mortals scream.

Hannya sat atop a cushioned seat, one leg elegantly crossed over the other, head resting on her knuckles. She looked thoroughly unimpressed.

"They always have to sing their requests?" she asked Noh, who sat beside her.

"They believe words spoken plainly are less binding than those delivered in harmony," Noh replied.

Baku leaned back in his own chair, his arms crossed. "That's a polite way of saying they're idiots."

One of the Bone Choir stepped forward, bowing low. "We request permission to place resonance stones in the cracks of the dream fissure. To harvest the song of madness sung by dream beasts as they awaken.~"

Hannya looked at the singing idiot strangely. "You want to make records of their screams?"

"They are not screams. They are notes. Pure notes from beyond sanity.~"

She gave them a radiant smile that held just a hint of teeth. "And what do I get for allowing you to harvest our screaming beasts?"

The leader extended a pale hand, opening a black box to reveal a polished skull. It glowed faintly with runes etched into every surface.

"The skull of the Eversinging Oracle. It will whisper hidden truths when submerged in mist.~"

Hannya reached forward, plucking it from the box. She turned it in her hands, fingers running across the grooves.

"This is a decent bribe." she admitted.

The Bone Choir straightened expectantly.

"But not a good enough one," she added, tossing the skull lazily to Baku. He caught it with one hand, blinking.

The bribe was dirty cop value; she was seeking more of an insider trading rhythm.

"I want three more things," Hannya continued. "First, the blueprints for your sound-stones. Second, a three-month record of your choir's tuning rituals. And third…"

She smiled wide.

"An oath that none of you will ever try to harvest a dream beast within a hundred meters of the fissure's core."

The leader hesitated. One of the choir members began whispering an alternate harmony,likely a dissent.

Noh drew her fan. The sound of metal sliding into wood was quiet but deadly.

The whispers stopped.

"…Your terms are accepted, Princess of Hazy Mountain.~" the leader said.

"Wonderful," Hannya purred. "Let's call this the start of a beautiful, mutually suspicious relationship."

After the Bone Choir filed out with eerie grace, Baku approached the throne, the oracle skull still in hand.

"You're building a network," he said. "Even if you won't call it that."

"I prefer to think of it as a web," Hannya said. "Much prettier. Much more honest."

Baku's gaze narrowed. "They'll want more than favors soon. And the deeper you get into these camps and cults, the less room you'll have to breathe."

"I don't plan on breathing," she said casually. "I plan on ruling, quietly, invisibly, from a place no one can touch."

She glanced sideways at him, eyes half-lidded.

"You'll protect me, won't you, Grandfather?"

SNORT

He knew it. Shameless! She was using him as a meat shield to make political maneuvers!

Baku was a sly fox too. Where would she be untouchable? Hiding behind him!

He gave the teen a vicious glare, but he didn't say anything. It wasn't like he'd say no. But he wouldn't give this brat the satisfaction of answering yes.

She giggled as she rose from her throne and walked off, robes draping against the stone. As she passed Baku, she tapped her hand lightly on his shoulder.

He felt a phantom ache run from that shoulder and directly to his head. He just wanted peace and quiet.

'She's always two steps ahead.' He thought, shaking his head. 'Not just because of her charm or cunning. She sees something… far beyond what anyone else here can.'

And yet… He didn't sense a Fate Mutation on her. No ripple in the river of destiny, no bending of probability. Just certainty. Too much certainty.

His master had a tell, but Hannya didn't.

He stared down at the skull in his hands, and felt a cold weight in his chest.

'What do you know, kid? And what will it cost this mountain to find out?'

~~~

Evening fell slowly on Hazy Mountain, the mist thickening like breath on glass. Most devil guests were returning to their chambers, drunken with dreams, defeated by negotiations, or simply too cautious to linger in the presence of the mountain's new princess.

But the true work of rule began after the sun bled out.

Baku joined Hannya beneath the fancy awning at the heart of her pavilion. A half-moon hung overhead, the sky pulsing softly with invisible auroras only visible from this peak. Noh sat nearby, silent as a ghost while playing a shamisen softly, her painted face unreadable.

A tea set was already prepared. The cups were fine porcelain, white as bone, and the tea inside shimmered with starlight. Not the real stars, fragments from a dream beast that once believed it was a constellation.

"You really do like gathering strays," Baku said, lifting a cup. "The Bone Choir, the Wisp Merchants, now that Blight Temple... All threads in your growing little tapestry."

Hannya sipped delicately. "Strays make the best allies. They're grateful. Hungry. Willing to kill to stay useful."

"You're playing a dangerous game," he said. "What if someone cuts the web you're weaving?"

"Then they'll be the ones who fall," she answered with a smile.

There was no arrogance in her voice. Only certainty. It disturbed him more than pride ever could.

"You're not like the nobles," Baku said. "Even now, after all that's happening, they think you're just another spoiled heiress given a fake title. 'Princess of Hazy Mountain', they think it's ceremonial."

Hannya set her cup down, fingers tapping once against the saucer. "Then they're fools."

As she suspected. They aren't interested in the events of Hellnia, not if it isn't within their capital.

The death of one of their own may have caused anger, but they think they have all the time in the world to get their revenge.

Immortals had such proclivities.

That's how the MC's drove out the devils, to their perspective, in the blink of an eye.

She turned, mist coiling from her sleeves like living threads, and looked toward the dark horizon.

"Haziness is a kind of truth," she said softly. "Let them think I'm ornamental. While I grind their ambitions to powder and scatter them like dust."

Baku was silent for a moment. Then he spoke, his voice low, thoughtful.

"Kid-"

TWANG

"Meiko, you sure about all this?" he asked.

"Kikiki, don't worry, Gramps. This is the path to the good end. I'm sure." She said, not a single ripple in her words.

Baku let out a sigh. "Then I'll continue to trust you."

He meant it. More than he liked to admit.

There was something... wrong about her. But also right. Like a blade forged from the dreams of something that shouldn't exist. She spoke with conviction not of devils, but of gods. Like she'd already seen where every path led, and simply picked the most elegant one.

And yet… she bore no Fate Mutation.

He wasn't sure, but his instincts told him that was the case.

That was what gnawed at Baku most of all. He had known seers. Some were powerful. Some were liars. Some had drowned in the currents of time they thought they could sail.

But Hannya? She didn't steer the river.

She walked across it.

He remembered the old stories of his master, one of a girl who would rise from the mists of Hazy Mountain, daughter of no bloodline, claiming no banner, and still reshape the very nature of devils and their pacts.

He never believed in prophecy.

Now, watching her, he wondered if prophecy believed in her.

She rose and moved beside him, looking out at the flickering lights of the mountain's descending paths.

"Soon," she said. "We'll host a true gathering. Not these petty noble games."

"And what will you offer them?" he asked.

She turned toward him. Her eyes shone with something deeper than devilish hunger. Something cold. Something vast.

"A seat at the edge of the world," she whispered. "And a chance to decide how it ends."

The mist curled upward like blooming roses.

And Baku, the stalwart sentinel of the dream fissure, could only watch.

Not as her master.

Not even as her equal.

But as the last soul on this mountain who understood that peace, in the presence of someone like her, was always the eye of a storm yet to break.
