"Huh, a stray exorcist?" the Fallen Angel mused, tilting her head as she eyed Jaune with amused curiosity. "So this is what you've been doing."
She was all curves and sin—voluptuous blue hair cascading down a body that seemed sculpted for temptation. Her crimson blazer hugged her figure just enough to make holy men doubt their vows.
"You know me?" Jaune asked, voice flat.
"Please…" She gave a throaty laugh. "The Grigori has been watching you. You, your sister… and the one wielding those cursed Norse swords."
"Because of our weapons, I take it."
"Of course," Kalawarner purred, hovered closer. "But you get more than just protection." She cupped her huge chest, groping them with a sly grin. "Considering the reason you and your sister were excommunicated… I'd say the Grigori would be more than willing to fulfill your needs."
For a moment, Jaune's brows dipped, not in shame, but in quiet memory. His sword pulsed in his grip, its cold hum washing over him, numbing any flicker of anger she had tried to spark.
"I see you were hunting a stray," she continued, glancing to the quivering and bleeding creature nearby. "Go on, finish her. Then we'll head back together."
"Bold of you to assume I'm here to kill her," Jaune said, raising his blade. "Or that I'd ever follow you."
Kalawarner chuckled, amused but not surprised. "You won't get far playing solo. I know you don't trust any faction after what the Church did. But at least the Grigori's honest about what it is." Her fingers trailed slowly down her thigh. "We don't pretend to be saints."
"Nah. I'm good."
He lifted the blade.
She frowned—not in anger, but calculation. A flicker of ancient intellect as The Watcher of God flashed in her eyes as her celestial mind connected the dots.
"I see." Her tone softened with pity. "Wherever faction you affiliated with Jaune… it's a trap. You just don't know it yet." Her eyes soften for a moment, "the world is not fair, and humans are treated less than dirt, even by their own kin."
"And that makes the Grigori better?"
"At least with us, you know what you're getting." She smirked. "Access to research. Protection. And if your sister's still as curious as you about dick and pussy...maybe a few orgies too." She finished with a promosing tone
That was when they felt it.
The night air, once cold...
...felt HOT.
It wasn't magic
It wasn't divine.
It wasn't demonic.
It was personal, intimate, and very human.
Anger.
A single clap of displaced air cracked the silence as Jaune launched forward, his broken sword clashing against Kalawarner's spear of light mid-air.
She blinked in disbelief.
That blade -- it was wrong. It pulsed with erratic energy, warping reality in bursts. One moment it was dull and crude. The next, it screamed with raw power, as sparks birth into life like a shudder.
Despite it's bright erratic hue, Kalawarner felt coldness, which can be mistaken as heat.
The coldness which burns you from the inside.
Regret.
Fustration.
Loathing.
Something she personally felt.
Then she saw his face; Jaune looked just as confused as she was, as if even he didn't understand how he'd closed the distance.
The blade flickered—then returned to normal, from its eratoc bright hue, to the dull blue-grey it held a moment ago.
Kalawarner's eyes narrowed. She slashed back with force and precision—
The world blurred.
Her spear swung through empty space—Jaune now 20 feet away, lying on the ground.
"Teleportation…? Illusion?" she muttered, eyes wide. Her scientific instincts flared. This wasn't magic. This wasn't dimensional. It was something else.
The lust vanished from her voice. Replaced now with morbid, ravenous curiosity.
"Well, kid… the sex can wait. You just became my new experiment."
-xXx-
"So, any new insights on our little curious case?"
"You mean, Jaune right?" Georg resisted to reply with a tense voice and remained stoic.
"Yes, anything on his blade?" Cao Cao said as he watch Georg scan a split pine tree, and curiously the split edge has a odd look.
Like as it its was a still image, stretch by the editor length-wise.
"Best we can tell is spatial abilities and reality-warping."
"Sound like a powerful weapon."
"But the draw back is when used too much, it disorients Jaune; makes him dizzy and confused." Georg then motions to the tree, "and there is the tendency of misfiring."
"Well... for a broken and dull blade, it does deal damage."
"Huh, well... that's not the blade's work. But Jaune's own strength."
Cao Cao looked confused, while he knows Jaune is a fighter and fought for the church... there is no way Jaune is that strong.
-xXx-
How can he be this strong?!
Kalawarner grit her teeth as sparks flew with a chime of a bell. Her muscles tense as she thrusted her spear in powerful and fast successions...
Not by the full edge of a blade—but by its absence. The jagged stump of Jaune's weapon met her strikes head-on, and the air cracked from the sheer force.
But something was wrong.
With every parry, her weapon flickered. Not just visually—but fundamentally. The spear shimmered like heat-haze, then stuttered, a split-second from unraveling into dust before it reformed again.
That shouldn't happen. Not with a Light weapon.
Angels and Fallen conjured them by instinct, maintained them through will. It was as natural as breathing. But now, her control stuttered, but not her will, like something was interfering with the concept of her spear existing.
Her eyes narrowed.
It wasn't just strength.
That sword of his...it was undoing things.
The Fallen rationaled, before feeling her weapon slammed into the ground with extreme force!
The earth broke upon impact as her weapon turning into sands of light.
The wind shifted when Jaune pivot with his blade!
Kalawarner saw cold eyes when just as a broken blade swung at her. The blade felt it would miss, but she is not taking any chances!
DING!CLANG!
Just as she thought, as once again the blade bit the new Spear of Light protecting her!
In her eyes, the human flickered for a moment, just as he appeared closer so that his excisting half of his blade made contact with her second Spear of Light.
A quick glance at her weapon just comfirmed her suspicions, as her weapon destablizes constantly before forming back into a spear.
She grinned, as she lifted her first blade and swung it to Jaune.
The human's eyes widen, as he stepped back haphazardly for his life, letting go of his blade.
Kalawarner was on him in an instant! As the Fallen flew to the sky!
Jaune saw the woman zoom towards him, with two vicious Spears of Light!
BAM!
AHHHH!!!
Muscles spasm in extreme pain, as every nerve flaired! Kalawarner never felt this kind of pain, as her throat turn harse when a Ki Bullet slammed into her!
The stray devil had her hand raised, Jaune believe that the magic was from her and didn't waste the opportunity.
He burst forward, Sad Sword appearing in his hand, raising above his head and slammed at Kalawarner.
The Fallen gritt her teeth, as the blade made crude and shallow cut, right below her heart! Jaune placed his weight on the pummel, but found the Fallen'a bones that tough.
Kalwarner found a semblance of strength, lashed at him.
Jaune grabbed the offending hand, then pinned it down to the ground with his broken blade!
AHHHH!!!
Kalwarner screamed! But it was cut short when a fist slammed into her face!
A fist clad in aura tighted, just as Jaune's other hand chocked the Fallen to the ground!
BAM! BAM! BAM!
Kalwarner head ached more, as her brain bore the pure impact of the punches!
The ground vibrated abit by each punch, as blood begin to pour with an aura clad fist tearing the skin of the Fallen. Her entire body flinched per impact as her tits jiggled per impact.
As for Jaune, he felt nothing but the numbness to finish the mission, as his new power pour out of his soul and slammed into his enemies face through his punches.
"ENOUGH!" She yelled just as she gained her motor functions from the Ki bullet.
BLAST!
Her free palm burst pure light, blasting Jaune away from her as the blonde rolled over the ground and slammed into a tree!
Jaune wobbled as he stood in pain, just as another light blast hit his torso! His aura flashed, then another one slammed at him, pushes him through a tree. Just as another bore down at him!
Kalawarner stood bleeding, face half-smashed, eyes like a serial killer. Her breaths came in ragged heaves as she yanked the Sad Sword from her pierced hand, a messy schlick of blood and torn flesh spilling down her arm. The blade flickered out of existence as she tossed it aside.
"Oh, I will have so much fun breaking you," she snarled, summoning a new Spear of Light, its glow searing and unholy. "That sword… that thing… Lord Azazel's going to make it his next pet project."
She spat blood. A tooth clattered beside her boot.
"Guess I'll just bring you in missing a few pieces."
Step.
A shadow moved.
Kalawarner paused mid-step as someone blocked her path. The stray devil—bruised, panting, trembling—stood between her and Jaune, arms up in a loose guard.
Two bloodied figures stared at each other, silent.
Then Kalawarner laughed, hard.
"Bwahahaha! What? You're protecting him now? The same brat who tried to kill you?"
The Stray's eyes twitched, like she wasn't sure of the answer herself. But her stance didn't waver.
Too much was happening with that boy. His strange ki, that broken sword that feels familiar yet extremely different. It felt… wrong. Or maybe, just different. And different might be enough.
Kalawarner's grin twisted into a sneer.
"I've lived centuries, seen angels fall, humans rise, devils burn, but today? This is new." Her eyes narrowed. "Not because of you, Stray. But him."
She raised her glowing spear.
"And I know your kind. Dangerous. Unstable. A mutt from a cursed race." Her voice turned to venom. "And yet you chose to become a devil. To kill your own master. Do you even understand what this does to you?"
The light of her weapon flared, bright and pure—poisonous to any devil.
"You think you can block me with a body already burning from the inside?"
The stray didn't move.
"I know," she said quietly.
Then her voice hardened.
"I'm tired of all of it."
Demonic energy rose like smoke. Yokai power followed; wild, bitter, scarred. The strain of it cracked the air. Even standing there was pain. The Light already seared her skin, digging into her blood like acid.
Kalawarner's stance shifted, instincts sharpening.
"I can kill you right now," the Fallen warned. "Light eats through your kind like rot. All I have to do is graze you."
The stray's eyes glowed with something ancient and furious, yet tired.
"I. Don't. Care."
Her voice trembled with exhaustion. And truth.
Light clashed with shadow.
And the Underworld felt a small earthquake that day.

Jeanne wanted to scream at Georg, her glare hot enough to sear through his coat.
Georg only sighed. "A massive magical spike triggered near your area. The devil nobles are bound to send someone to investigate."
"But you didn't even—!"
"A risk we couldn't take," Cao Cao interrupted, sharp and controlled before Georg could defend himself. "The world doesn't know what we are yet. I intend to keep it that way."
He didn't flinch at her anger. Let her rage. Emotion clouded judgment.
One soldier was expendable if it meant the movement survived.
Jeanne's fists trembled at her sides, chest heaving. Her eyes were still that of a girl—not yet hardened by the reality of war.
"Please, don't worry, Miss Jeanne," Georg offered, his tone flat but softened by something faint. "We can still find him."
"What's the chance he's still alive?" Sieg asked, his voice edged with urgency.
Georg hesitated. "Hard to say. He's good—but the Underworld…"
"…is a different breed entirely," Cao Cao finished. "If things went south, your brother may already be dead."
He didn't enjoy saying it—but someone had to.
Jeanne's world cracked. Her knees gave out, and Sieg caught her before she could fall completely. Her breath hitched. Her thoughts spiraled.
If it wasn't for me. If I just stayed pure. If I hadn't entertained those feelings…
"Hey guys," a hoarse voice broke through the tension.
They turned.
Jaune stood in the tent's entrance; burnt, bleeding, soot staining his ruined clothes. Smoke curled from his hair, and his stance barely held. But his eyes… his eyes were clear.
Cao Cao narrowed his gaze.
So. The boy survived.
Jeanne barely processed his voice before she stumbled forward; shoving past Sieg, nearly tripping over herself.
"Jaune!"
She crashed into her brother, arms wrapping around his burned frame like she feared he'd vanish again if she blinked. He didn't cry out despite the wounds. Just rested his chin atop her head.
Cao Cao watched in silence.
Emotion made people soft. But in rare moments. Dangerous. Motivating.
Jaune didn't look like much now—smoke-streaked, pale, clothes torn apart. Yet he stood. And that meant more than Cao Cao wanted to admit.
He crossed his arms. "Georg," he said, voice low, "notify Hercules. We will include Jaune Arc to the list."
Georg gave a curt nod, though his eyes flicked briefly back to the twins. That same quiet, persistent concern. Predictable.
Cao Cao didn't fault him for it. Everyone had attachments. But only a few knew when to cut them loose.
His gaze shifted back to Jaune.
The boy's hand still trembled behind Jeanne's back. Hidden from her. Not from him.
He was holding it together for her.
Cao Cao tilted his head slightly. That sword… the one from earlier. No signature. No logic to its form. And yet… it broke light. It split certainty itself.
He narrowed his eyes. There was potential there. Not just in the blade—but the wielder. Whatever happened out there hadn't broken him. It had sharpened something.
"Tend to your wounds," Cao Cao finally said aloud, calm as ever. "We'll talk soon."
He turned from the siblings and stepped into the night air outside the tent, the stars above reflecting cold and endless across the sky.
The board had shifted tonight.
And Jaune Arc was no longer just a pawn.
-xXx-
Well Jaune didn't have time to tend his wounds.
"Here" he handed a bag of bread and water.
"Thank you." The woman received it with a faint but suspicious smile, "Are you sure this is a good idea, Jaune?"
Jaune gave the stray a flat stare, "Like you are going anywhere, Kuroka."
