Some scars never fade.
Some wounds closed.
Dawn had broken by the time they returned to the Gremory estate.
On the surface, everything was quiet. But beneath the polished marble and drifting cherry blossoms, emotions coiled like unseen currents. Plans were forming. Bonds were shifting.
And something older had begun to stir.
⸻
The East Wing
The east wing was the living quarters for Rias and Lucien's peerage members.
The Gremory estate wore peace like a carefully arranged mask.
Sunlight filtered through enchanted glass. Cherry blossoms drifted endlessly in the courtyard below, caught in spells that denied the passage of seasons. Servants moved softly through the halls, voices hushed, footsteps measured.
But beneath it all, something had shifted.
The kind of shift that didn't announce itself.
The kind that waited.
Kuroka lay propped in a luxurious bed surrounded by silken pillows. Her body was wrapped in layered healing sigils that glowed faintly gold and pale blue. Her new and old wounds alike were closing, slowly but stubbornly, the alchemical poison still resisting the estate's magic like a dying curse.
Kuroka's scent still carried traces of snow and blood beneath the healing incense.
For the first time in years, she wasn't sleeping with one eye open. She could finally let her guard down.
Outside, Lucien leaned against the wall, arms folded loosely across his scarred chest.
Koneko's gaze lingered on the bandages enveloping Lucien's scarred chest.
"Thank you… for saving her," she whispered.
He placed a hand on the younger Nekomata's head and wiped away a fresh tear from her cheek.
"You don't have to thank me, Koneko, just give a few extra cookies, and we can call it even."
He ruffled her hair one last time like a caring older brother, "Now go see your big sister."
Koneko gave Lucien a light hug, trying her best not to harm any of his injuries.
The Reunion
The door creaked open softly.
Koneko stepped inside.
Small.
Hesitant.
Behind her eyes, she was carrying the weight of old ghosts. Her footsteps barely made a sound against the marble floor.
Kuroka's eyes snapped open.
"…Shirone."
Koneko stiffened immediately.
"Please…Don't call me that," she said, her voice quiet but firm. "I go by Koneko now."
Silence followed.
Not empty.
Not calm.
Heavy.
Like something waiting to break.
"I missed you," Kuroka said.
No teasing.
No grin.
Just truth.
Koneko didn't respond at first.
She stood there, staring.
Searching.
Measuring the woman in front of her against the ghost she remembered.
Koneko's fists trembled at her sides. Her voice cracked as tears welled in her eyes.
"You promised we would always be together," her voice breaking as tears began to form. "You promised we'd always be family… but you left me. If the Gremorys hadn't found me, I would've died alone."
Kuroka closed her eyes as pain flashed across her face.
"I tried… I really did. They were already watching you. If I'd taken you with me, they would've marked you too. You would've been hunted like me. I thought leaving you was the only way to keep you safe."
Koneko shook her head, tears falling freely now.
"But that didn't stop you from leaving me."
"No," Kuroka said immediately. "It made it survivable."
The room felt smaller.
As if the past had stepped inside with them.
Her fingers curled weakly into the sheets.
"You would've become what I was. A stray. A target. A weapon."
Koneko's voice dropped.
"…So you decided for me."
Kuroka flinched.
"…I chose the only outcome where you lived."
Silence fell over the room again.
But shorter this time.
"I waited, you know… even after they told me you were gone. I kept hoping you'd come back for me."
Her grip tightened at her sides.
"I kept waiting to hear your footsteps outside my door."
Kuroka's breath hitched.
"…I wanted to."
Kuroka reached out, and in that moment, the years of anger, fear, and loneliness between them cracked. She embraced Koneko tightly, both sisters crying over their shared pain.
"I'm so sorry," Kuroka whispered, her voice tight with guilt. "I thought it was best… I thought you'd be safer without me."
Koneko wiped her tears and looked up at her big sister, "Tell me the truth.… About us."
Kuroka's gaze lowered to meet Koneko's deep eyes.
She let out a low sigh before answering her sister's question.
"…Our father wasn't just strong," Kuroka said quietly. "He was a descendant of the Byakko."
Koneko blinked.
"…The White Tiger?"
Kuroka nodded faintly.
"The strength you hate? The one you try to suppress?"
Her golden eyes softened.
"It's not something broken inside you."
A small, fragile smile.
"It's him."
Koneko froze.
Something inside her shifted.
"…What about our mother?" she asked.
Kuroka's expression dimmed.
"…She gave us instinct," she said. "Survival. Adaptation. The ability to become something more… or something worse."
Outside the door, Lucien remained still, listening but not intruding. A quiet warmth bloomed in his chest, unfamiliar enough that he almost didn't recognize it.
⸻
Medical Wing
Grayfia found Lucien resting against the wall.
"Lucien," she said gently. "Come."
He hesitated for just a second.
Then nodded.
The shadows near his feet shifted unnaturally against the morning light.
Lucien didn't notice.
But Grayfia did as she escorted him back to the medical wing.
The room was pristine.
White stone. Silver etchings. Magic layered so densely that the air itself felt structured.
Lucien sat on the edge of the bed as healers finished their work, fresh bandages wrapping his ribs and right arm.
They bowed and left.
Grayfia raised a hand.
A barrier unfolded instantly, sealing the room in silence.
"…That was not Destruction magic," she said.
No accusation.
Just a cold, hard fact.
Lucien didn't try to pretend otherwise.
"…No, mother, it wasn't."
A shadow stirred faintly at his feet.
Subtle as if it was listening.
Grayfia's gaze lowered to it.
"…I had hoped it would awaken later."
Lucien frowned.
"…You knew?"
She stepped closer.
Grayfia's gaze dropped to the shadows pooling unnaturally at his feet.
"Shadow authority," she said quietly. "Not spellwork. It is older than that. It runs through your grandmother's line."
Lucien stilled.
He felt the darkness shift, almost as if it were listening.
There was a pause before she continued.
"The kind that exists whether you acknowledge it or not."
Lucien's fingers tightened.
"…It didn't feel like power."
Grayfia met his eyes.
"No."
"It felt like something was calling to me."
There was a flicker of movement at the edge of his vision.
Gone when he looked.
Grayfia turned slightly.
"Grayroad."
The air folded.
And he was there.
Silent.
Watching.
"He will remain close," Grayfia said. "Until your awakening stabilizes."
Lucien gave a small, tired breath.
"…Was it that bad?"
⸻
The Question
Before heading to his room, Lucien stopped to check and talk to Kuroka.
He knocked only once before he was told to enter.
Kuroka gave a faint smile as she looked at Lucien.
"You look like hell," Kuroka smirked.
"Funny. I was going to say you clean up nicely for a stray."
She rolled her eyes. "So what now, Gremory boy?"
Lucien crossed the room and paused by the window, watching the enchanted wind dance through glowing petals.
"For now? You rest. Heal. Reconnect with your sister. Teach her what you can. Then, when you're ready… you'll join my peerage."
Kuroka's ears twitched. She opened her mouth, then hesitated, an uncharacteristic flicker of uncertainty in her amber eyes. For a moment, Lucien saw something raw and vulnerable beneath the teasing mask.
"You're that sure about me?" she asked softly.
Kuroka studied him quietly.
Most devils looked at broken things and saw liabilities.
But Lucien was different. He looked at them like they still had a future.
"No," Lucien admitted. "But I believe in second chances. And you've earned it more than anyone."
Kuroka studied him for a long beat, then let the moment pass with a familiar smirk. "I could get used to this view. You're easy on the eyes."
Lucien chuckled. "Careful. If Serafall hears that, I may never hear the end of it."
Kuroka blinked. "Serafall Leviathan?"
"Yeah."
Her grin sharpened, all cocky Nekomata once more. "Then she'd better bring her A-game. I play for keeps."
A sudden, irrational chill ran down Lucien's spine. Somewhere in the estate, he was certain Serafall just sneezed.
⸻
Lucien's Room
Lucien lay back against the headboard, a manga volume open in his hands.
A freshly released chapter of That Time I Got Reincarnated as a Slime.
Of all things.
Bandages wrapped his torso.
His arm rested stiffly at his side.
Peaceful.
Almost.
The door opened without knocking.
Rias entered first.
Akeno trailed in behind her.
Rias stopped the moment she saw him.
Her expression tightened.
"…You're worse than you look."
Lucien glanced up.
"…I'll take that as concern."
Akeno stepped in, amusement already dancing in her violet eyes.
"My my… those bandages," she said, covering her mouth lightly. "Do you need a personal nurse?"
A pause.
"Oh wait… I forgot."
A sly smile.
"You already got yourself a little kitty."
Lucien snorted.
"Akeno," he said lazily, flipping a page, "I'm pretty sure there's a nurse outfit somewhere in this estate with your name on it."
Rias pinched the bridge of her nose.
"…Can you two not?"
Akeno's smile softened.
"Aw, don't be like that. We didn't come to tease you," she said.
Lucien closed the manga.
Now attentive.
"…The power matrix," Rias said quietly.
And just like that—
All the warmth in the room vanished.
Elsewhere, while the Gremory estate settled into uneasy calm, another gathering began.
⸻
Elsewhere — The Old Devil Faction
Far away, in the scorched remains of a forgotten citadel buried within a dimensional fold, a shadowed council gathered. Cloaked figures surrounded a flickering projection of Kuroka's failed capture.
The leader snarled, "The Lucifuge heir snatched the asset right from under us."
"And protected by him," another hissed. "Grayroad… the one we missed."
"Impossible. We wiped out his entire bloodline, every cursed blade, every silent monk. The clan of shadows should be extinct."
"They were the Lucifuge's hidden blades," spat a third. "Boasting of unmatched stealth and sorcery. Arrogant to the end but deadly. They fell only because we brought down an entire mountain to bury them and lost a lot of manpower to end them."
"We thought we ended them. But somehow, the child survived."
"And now he guards her like they once guarded the Lucifuge princess. The oath survived."
Silence followed.
"…Then Grayfia inherited it."
"She made him her blade," another said coldly. "Trained him in silence, hidden in the folds of war. A living shadow. Silent. Loyal. Deadly."
"And now… she's given him to her son."
"They're a matched pair," the eldest rasped. "The mother, the frost queen with the mind of a tactician. And the boy… something new. Unshaped. Unyielding. Dangerous."
"Then we must finish what we started."
"No. We failed once. We won't get another chance."
"Project Chimera must continue," a voice whispered. "But Lucien Lucifuge must be divided. Isolated. Or he will become worse than his mother."
"Worse?" a voice sneered. "He'll unite the broken bloodlines and bury us beneath the weight of legacy."
"And if Grayroad stands beside him…"
"Then this time," the eldest whispered, "we die for real."
Courtyard of the Gremory Estate
As the sun dipped below the Underworld's crimson skyline, the family gathered in the courtyard. Rias leaned against Lucien, half-teasing, half-sincere.
"You always throw the house into chaos."
He grinned. "It's a gift."
Sona, seated across the chessboard, studied him carefully. "I think your 'gift' is more calculated than you let on."
Grayfia returned with a tray of tea, graceful as ever. "He's growing into the role he was born for."
Lucien raised a brow. "Any chance that role comes with less training?"
Sirzechs, sipping his tea, scoffed. "I'm increasing it tenfold."
Everyone groaned except Kuroka, who laughed. "You'll thank him later."
⸻
Garden at Dusk
The sky burned red and gold.
The pool reflected it like liquid fire.
Lucien sat at the edge.
Waiting.
Sirzechs arrived without ceremony.
"You've changed the board," he said.
Lucien didn't look back.
"…Feels like the board changed before I even made a move."
A faint smile.
Sirzechs stepped beside him.
"You and Rias will be receiving your Evil Pieces soon."
Lucien blinked.
"…That fast?"
"Tell me, are you ready?"
A faint smirk appeared on his father's face.
"And you'll need partners."
Lucien narrowed his eyes.
"…What did you do?"
Sirzechs smiled.
Dangerously.
"I arranged your betrothals."
" …Rias is fighting to escape one arranged marriage, and your solution is to give me two?! Are you serious? "
Two portraits appeared.
Floating.
Lucien looked.
Then froze.
"…No way."
One woman radiated cold authority. Silver hair. Ice in human form.
The other presence that felt like elegance wrapped around something monstrous.
"…They look like…"
He stopped himself.
Sirzechs tilted his head.
"Like what?"
Lucien exhaled slowly.
"…Nothing."
But his thoughts were loud.
Too loud.
Something about this world had already drifted away from the story he remembered.
⸻
The Weight of Legacy
Night settled over the estate.
Lucien remained in the courtyard alone.
Starlight cast long shadows across the obsidian stones.
The weight of legacy pressed in from all sides.
Lucifuge.
Power.
Shadows.
Expectation.
Somewhere unseen, the darkness stretched.
Curled.
Not hostile.
Not kind.
Patient.
And somewhere deep within.
That same voice he heard before his reincarnation.
Soft, almost amused.
You've only just begun.
