The warm afternoon sun filtered through the tall windows of the Gremory estate's sitting room, casting dancing shadows across a polished chessboard. Three teenagers sat in focused silence.
Lucien lounged sideways in a velvet armchair, one leg crossed lazily over the other, idly spinning a bishop between his fingers. Across from him, Sona Sitri tapped her chin, glasses glinting as she calculated. Rias sat between them, arms folded beneath her impressive bust, already eliminated from the round but watching with sharp interest.
Lucien studied the board, feeling every piece as an echo of his own position. His knights and bishops, the aggressive, unconventional choices he wanted to make with Kuroka, looked exposed. Sona's pieces formed a patient, methodical wall, much like the noble houses watching and waiting to see if the Lucifuge-Gremory heir would stumble.
"Knight to E5," Lucien spoke at last.
Sona blinked. "Aggressive. Almost reckless."
"Calculated risk," he replied, the words carrying more weight than the move itself. "You taught me to sacrifice when necessary."
The move felt exactly like reaching for Kuroka: bold, potentially costly, but necessary if he wanted to break Koneko free from her self-imposed cage. Yet the board clearly showed the danger. His knight now hung vulnerable, open to capture, just as his plan could invite political backlash or worse.
"Your knight for my rook is still a questionable trade," Sona noted.
Lucien shrugged. "Sometimes what seems inefficient at the moment creates pressure later."
Rias smiled faintly, brushing a lock of crimson hair behind her ear. "You're sounding more and more like my brother."
Lucien smirked, though the expression didn't reach his eyes. "He cheats. Subtle magic nudges when no one's looking."
Rias retorted, "He does not!"
Lucien replied coolly, "You've never played him drunk."
That earned a reluctant snort from Rias as Sona made her countermove.
"Check."
The single word landed like a ward ripple. Lucien stared at the board, the narrowing paths suddenly feeling too familiar. His king had fewer safe squares with every turn. The pieces he wanted to protect (Koneko's future, his own ideals, his second chance) were being hemmed in by forces he couldn't yet see clearly on the board… or in life. External hands were moving: Sirzechs weighing options, rival houses stirring in the shadows, the Underworld's expectations pressing down like an invisible rook.
He could see the collapse coming if he pushed too hard or too soon.
And maybe, he thought grimly, that was the real lesson today.
Lucien tipped his king. "Well played."
"You rushed your endgame," Sona observed, already resetting the pieces with precise movements.
"Maybe," Lucien said, straightening in his seat. "Or maybe I had something on my mind."
Sona quirked an eyebrow. "Is it about Kuroka?"
Rias froze.
Lucien caught it instantly, the subtle shift in her shoulders, the flicker in her eyes as her gaze slid away. His voice softened with genuine surprise. "You didn't know?"
She shook her head. "No… Koneko never talks about her."
"She won't," Lucien murmured, watching enchanted ward-lights dance overhead and cast shifting shadows across his crimson hair with its silver tips. "She's terrified we'll see her as just another stray."
"But you're trying to find Kuroka? Why?" Rias asked, her voice quieter now, the playful Gremory edge replaced by something fragile.
Lucien leaned back, eyes drifting to the ceiling. "She's Koneko's only blood relative. Whether she was right or wrong to kill her master… the official records were written by those with something to conceal. Truth here is more shadow than substance… and far less honest. If Koneko stays haunted by that fear, she'll never truly grow."
Rias looked at him with awe, concern, and a flicker of guilt crossing her face. She had seen the fear in Koneko's golden eyes and looked away, like so many devils did when discomfort arose.
Lucien leaned forward, voice quiet but intense. "Ri Ri… imagine if it were you or me. Separated. Misunderstood. Judged for choices we never got to make. If Kuroka is truly irredeemable, I'll stop her. But I need the truth for Koneko's sake… and maybe for hers."
She blinked, visibly caught off guard.
"Separated. Misunderstood. Judged for choices we never got to choose."
He let the words hang there, heavy with meaning.
Rias hesitated, then nodded slowly. "Then I'll support you… whatever you need."
She had always seen herself as Koneko's protector. Perhaps Lucien was fighting for the girl's very soul.
Sona cleared her throat, reclaiming detachment. "Emotional logic in recruitment strategy. Can be risky."
Lucien chuckled, low and edged. "It's devil logic. Power tempered by connection. We don't just rule, we protect. Or we should."
Before anyone could reply, a subtle ripple passed through the estate's wards, a familiar cold signature brushing the room like winter wind.
Lucien felt it first: a prickle at the base of his neck.
⸻
Deep below, in a hidden archive beneath the estate, Sirzechs stood alone, fingers trailing over an ancient crystal orb that pulsed faintly with light. Suspended beside him floated a sealed intelligence file, the name on the cover unmistakable:
KUROKA
"She killed her master," came a shadowed voice from Grayroad. "But the energy discharge showed irregularities. No offensive intent until the final blow."
Sirzechs narrowed his crimson eyes. "Meaning she reacted. Not initiated."
"Correct. Her master experimented on demonic hybrids. Records were redacted. Ties to Old Satan remnants exist."
The crystal flickered. Sirzechs' jaw tightened.
"He suspected the gaps," Grayroad continued. "Sharper than most realise."
Sirzechs exhaled, running a hand through his hair. "I gave the boy space… but this changes things." His voice dropped, cold as a winter night. "Continue investigating. Quietly. If there's any cover-up or innocence, I want it before the Council stirs."
He turned from the orb, gaze lethal. "And double Lucien's combat regimen."
"Double?"
"If he insists on taking on these risks, he must be strong enough and smart enough not to die for ideals." Sirzechs' tone softened at the edges. "He's my son. I won't lose him to the same shadows I've spent the first half of my life fighting."
The orb dimmed. The chamber fell still.

High above, in the sunlit training grounds behind the estate, Lucien stood opposite his mother.
Grayfia Lucifuge watched with steel-blue precision, her silver hair pinned perfectly, even in her maid's uniform. "Again."
Lucien nodded, sweat already beading on his brow. His crimson hair with silver tips clung damply to his forehead.
He raised a hand. A weak swirl of Power of Destruction flickered, unstable, hungry, devouring his reserves far too quickly. The crimson-black energy lashed out at a training dummy, shredding half of it before sputtering out and leaving him breathing hard. The drain on his magic was immediate and punishing.
"Control your output," Grayfia instructed calmly. "Do not let it consume you."
Lucien switched tactics, forming intricate magic circles with practised ease, high control, glowing arrays that stabilised barriers and minor spells without effort. Then he attempted basic ice magic: a modest shard formed, sharp and cold, but nowhere near the devastating scale he knew was possible in theory.
Spatial magic remained locked in books and equations, theoretical only, unusable for now. And deeper still, something dormant stirred in the shadows, a darker potential he hadn't yet touched.
He tried the Power of Destruction once more. It surged violently, draining him so heavily his vision blurred for a moment.
Grayfia caught his arm before he staggered. "Enough for today. You push too hard."
Lucien straightened, wiping sweat from his eyes. "I have to. The board is moving faster than I expected."
Grayfia's expression remained composed, but her grip lingered a fraction longer maternal beneath the queen's mask. "Then we train harder. Together."
Unbeknownst to Lucien, far away, the game had already shifted in ways no one in the estate could yet see.
In the opulent halls of the Vermeil Succubus Clan, information moved faster than magic and cut deeper than any blade.
The Midnight Markets never slept. Whispers were currency. Secrets were collateral. And every shadow belonged to her.
Vermeil lounged upon her gilded throne, posture relaxed, one leg crossed over the other as though the world itself moved at her convenience. Her violet hair flowed down her shoulders in soft waves, framing a face that carried no urgency, only quiet, dangerous awareness. Small horns curved from her head, elegant rather than imposing, like a crown worn by something that had never needed to prove its dominance.
Her golden eyes drifted lazily toward the envoy… but there was nothing lazy about what lived behind them.
She had read the report three times.
Verified it twice.
And decided before the man finished kneeling.
"The Lucifuge heir…" she murmured, voice soft, almost absent-minded, as if the name were a passing curiosity rather than a political storm.
One slender finger tapped lightly against the armrest.
"Powerful lineage. Political gravity. And… instability."
A faint smile touched her lips.
Now that… is interesting.
Around her, unseen but ever-present, her network breathed. Assassins. Informants. Brokers of sin and silence. The Vermeil Clan did not react to the world.
They knew it before it happened.
"And a boy," she continued, tilting her head slightly, "standing at the centre of a board that's beginning to shift faster than its players realise."
Her eyes lowered briefly, thoughtful.
Then curved again, sharper this time.
"A child reaching for something dangerous… or something necessary."
A soft laugh slipped free, quiet as silk sliding over steel.
"Yes…I'd like to see what he'll become."
Her gaze finally settled fully on the envoy.
Not heavy.
Not forceful.
Just enough to make his breath catch.
"Tell Sirzechs," she said, voice smooth and certain, "the Vermeil Clan is… interested."
A pause.
Then, almost as an afterthought:
"And have the Midnight Markets keep eyes on him."
Her smile deepened, something ancient and predatory flickering beneath the warmth.
"I want to know who reaches for him next…"
In the frozen training grounds of the Glasya-Labolas Clan, Esdeath sheathed her blade with a crisp snap after another flawless session. Ice still clung to the air, shattered dummies frozen solid around her.
A maid approached, bowing deeply. "Lady Esdeath, the clan has received a proposal from Lord Sirzechs Lucifer. A betrothal to his son, Lucien Lucifuge-Gremory."
Esdeath's blue eyes sharpened with sadistic delight. A slow, predatory smile spread across her lips.
"The strong survive. The weak are conquered." She drew her sword again, frost blooming along the edge. "If this heir proves worthy… he may earn my loyalty. If not…" She laughed, cold and thrilling. "I will enjoy testing him."
The maid shivered. Esdeath settled into her stance once more, ice magic crackling around her like a waking storm.
The maid turned to leave, but Esdeath's words stopped her. "Tell me… does he break… or does he adapt?"
The board had shifted.
And for the first time…
Lucien was no longer the only one dictating the game.
