Silas felt the weight of their expectant stares like warm spotlights on his skin. He hadn't planned on showing them tonight—not really—but the way Rias's crimson eyes glittered with quiet challenge and Akeno's lips curved into that dangerous, honey-sweet smile told him postponing would only fan the flames higher.
With a slow exhale he pushed himself up from the plush leather couch, the fabric whispering against his back as he rose.
"Okay," he said, voice low and deliberately casual, "let's go. It's about time anyway."
"Don't worry," Akeno purred, stepping closer than strictly necessary, close enough that Silas caught the faint sweet-spicy scent of her perfume—something like vanilla and storm-charged ozone.
"If you disappoint… we won't laugh." Her voice dipped into velvet teasing territory. "Much."
Silas let a slow, dangerous smirk spread across his face. He tilted his head just enough to meet her gaze head-on.
"Oh, laughing is the last thing you'll be doing once you see it," he said, letting the words roll out smooth and confident. "That's for sure."
Akeno's eyes widened for a fraction of a second—genuine intrigue flashing beneath the flirtation—before her lashes lowered coyly.
"Ohhh…" she breathed, drawing the sound out like she was tasting it.
Then she leaned in, lips brushing dangerously close to his ear as she whispered, "That makes it so much more exciting."
She finished with a slow, deliberate wink, the kind that promised trouble of the very best kind, before stepping back with an innocent little sway of her hips.
Silas shook his head, half-amused, half-exasperated, the corner of his mouth twitching.
'She's one crazy girl,' he thought.
Rias cleared her throat softly—more amused than disapproving—and gestured toward the hallway that led down to the basement training area.
"After you, Silas," she said, her tone warm but edged with anticipation. "I'd hate to keep Akeno waiting any longer. She's already vibrating."
Akeno gasped in mock offense, pressing a hand to her chest. "Rias! I do not vibrate. I… quiver delicately with anticipation."
Silas snorted despite himself and started walking, feeling the two heiresses fall into step behind him. The air seemed to thicken the closer they got to the door, charged with curiosity, challenge, and something dangerously close to hunger.
He reached for the handle, paused for half a heartbeat, then glanced back over his shoulder.
"Last chance to back out," he said, eyes glinting. "Once you see this… there's no un-seeing it."
Akeno's smile turned positively feral.
"Good," she whispered.
Rias simply placed a steady hand on his shoulder, her touch cool and sure.
" I'll be the judge of that"
And with that, he turned the handle.
...
Kuoh lay shrouded in heavy, moonless darkness, the city's usual restless hum muted to an uneasy whisper as night claimed its dominion. Streetlights flickered weakly on distant avenues, but here—in this forgotten corner swallowed by weeds and cracked asphalt—the light barely reached.
The group stood before the husk of an abandoned multi-story building, its silhouette jagged against the starless sky like broken teeth.
Once perhaps an office block or warehouse, now it was only a skeleton of concrete and rusted rebar. No windows remained intact; every pane had long since shattered or been pried away. No graffiti scarred the outer walls either that any living soul had bothered to claim or even mock this place in years.
That unnatural cleanliness unnerved more than any vandalism could have.
A faint, metallic chill hung in the air, carried on a breeze that smelled of wet stone, old mildew, and something sharper—something alive and wrong.
Silas tilted his head slightly, eyes narrowing as demonic senses brushed against the building like invisible fingers. The others felt it too: Rias's crimson gaze sharpened, Akeno's playful smile had thinned into something more predatory, Kiba's hand rested near his sword hilt, Koneko simply stared silently.
Silas broke the silence first, voice calm but edged.
"It's below us," he said, gaze dropping to the cracked pavement at his feet. "Probably in a basement—or whatever's left of one."
Without waiting for replies, he stepped forward. The threshold of the main entrance yawned like an open mouth; the double doors had rotted or been torn away long ago, leaving only twisted metal hinges clinging to the frame.
Rias and her peerage followed in a loose, practiced formation—silent footsteps on debris-strewn concrete.
The moment they crossed inside, the temperature dropped sharply, as though the building itself resented their presence.
Silas halted abruptly just past the entrance, boots grinding dust into the floor. The others froze behind him.
The darkness inside was near-absolute, broken only by slivers of faint city-glow filtering through high, broken windows far above. But that wasn't why he'd stopped.
Directly ahead of them, the floor simply... ended.
A massive, roughly circular hole gaped in the center of what had once been the lobby—easily ten meters across, edges crumbled and blackened as though scorched before being eaten away by time and water.
And it was filled—completely filled—with water.
The surface lay unnaturally still, a black mirror reflecting the faint light that managed to reach it.
The water was so dark it seemed to drink the illumination rather than reflect it, only the tiniest silver ripples betraying that it was liquid at all.
The flooded abyss stared back up at them, patient and hungry, its black surface barely rippling now, as though the thing below had already sensed their arrival and decided to play dead—or pretend to be patient.
Rias tilted her head, crimson hair catching the faint sliver of streetlight that managed to sneak through the shattered windows high above. A teasing lilt curled into her voice.
"Can you swim?" she asked, lips twitching with amusement.
Akeno let out a soft, melodic chuckle that echoed strangely in the cavernous, empty space, like wind chimes in a graveyard.
Silas turned to face them fully then, the ghost of a grin tugging at his mouth. His eyes—usually so calm—now held a spark of something almost playful.
"Wait here," he said simply.
And without another word, he reached for the hem of his dark shirt.
The girls froze.
He peeled the fabric up and over his head in one smooth motion, muscles shifting and flexing under pale skin kissed by faint scars—old battles etched like faint silver rivers across his shoulders, chest, and abdomen.
The candle-like glow from outside carved sharp shadows into every ridge and valley of his toned physique: broad shoulders tapering to a narrow waist, the defined V-lines disappearing beneath the waistband of his dark boxer briefs.
Akeno's breath hitched audibly. Rias's eyes widened a fraction before she schooled her expression, though the faintest flush crept up her neck.
Even Koneko—usually unflappable—blinked rapidly, small hands curling into loose fists at her sides as her golden eyes traced the lines of his body before darting away, cheeks blooming pink.
Silas kicked off his shoes next, then his pants, stepping out of them with casual indifference. He stood there a moment in nothing but black boxer briefs that clung just enough to leave very little to the imagination, completely at ease under their stares.
Then he turned toward the edge.
And dove. A clean, powerful arc—arms extended, body slicing into the inky water with barely a splash at first, then a deep, resonant SPLASH as he disappeared beneath the surface.
The water closed over him like oil, ripples spreading outward in slow, hypnotic circles.
Down below, the darkness was absolute to human eyes.
To Silas, it was merely dim.
The flooded basement stretched far wider than the hole above suggested—almost like a natural cavern that the building had collapsed into over decades.
Pale bioluminescent flecks drifted in the water like lazy stars. And there, suspended in the center like a trophy on display, floated the Stray.
She was breathtaking.
Long, flowing hair the color of seafoam and moonlight undulated around her like living silk. Iridescent scales shimmered along her lower body, transitioning from deep indigo to pearl at the flaring tail.
Full lips curved in an enchanting, predatory smile that had doubtless lured countless men to their doom—eyes glowing softly violet, promising every desire they could ever name.
She tilted her head, smile widening as if to say *come closer, darling*.
Silas met her gaze.
And winked.
In the same heartbeat, raw power surged from his eyes alone—silent, invisible, unstoppable.
A pulse of pure, searing Purple energy erupted outward in a perfect sphere.
*BWHOOSH.*
The water itself screamed—vaporizing in violent bursts around the edges of the blast. The mermaid's enchanting smile froze, then shattered as her body disintegrated in a flash of light and shadow, not even ash left behind.
The shockwave rolled through the flooded chamber, sending violent tremors up the walls; chunks of old concrete cracked and fell in slow motion through the water.
Above, the surface of the hole erupted.
Rias and the others staggered back a step as waves slapped against the broken edges, sending cold spray across their legs and faces. The entire building groaned, dust sifting from the ceiling like dark snow.
Then—silence.
