The ventilation shaft thrummed faintly beneath Akio’s boots, each step measured, deliberate, nearly soundless. Dawn Hound gear muffled his movements as he glided through the narrow passage, the cool metal brushing past him in a blur. His breath stayed even, his pulse steady—mind locked into that familiar, razor edged clarity that arrived whenever a mission demanded nothing short of perfection.

  Below him, through the thin slits of the venting, the facility glowed in fractured patches of green and white, machinery humming like an organism struggling to stay alive.

  He scanned the chamber beneath with clinical precision, tracking movement and structural weaknesses. He spoke softly, projecting his voice into the comms.

  “Ten minutes.”

  Gabriel’s response came instantly, a low crackle of static riding his voice. “Copy that.”

  Akio vaulted over a support beam without breaking stride. Ten minutes was aggressive for this operation—tight margins, little room for error. But the facility wasn’t on the verge of exploding, nor was there an imminent threat demanding evacuation.

  His urgency was… personal.

  Aira had arranged for him to meet her friend today, Hyakki. She’d been excited in that earnest, radiant way of hers, insisting that he show up. Akio had promised he would. And he would never break a promise to Aira.

  So the only option, naturally, was to finish this mission early.

  He slipped out of the vent and onto a suspended platform, then dropped into a controlled slide along its surface, momentum carrying him toward the central chamber. The air shifted as he landed on the narrow ledge overlooking the heart of the facility.

  The chamber below stretched wide and hollow, dimly lit except for the unsettling emerald glow emitted by the central tank. Liquid swirled faintly inside it, casting ripples of fractured green light across the grated metal floor.

  Akio dropped from the ledge, cloak fanning behind him like a shadow detached from its source. His boots touched the grate without a sound. He straightened smoothly, weapon hanging loosely in his grip—primed in the same way a calm storm hangs just above the horizon.

  His gaze locked onto the far side of the chamber where darkness pooled deepest, clinging to steel and angled supports. It looked empty. Quiet. Innocent.

  Akio knew better.

  He remained perfectly still, breath steady, shoulders relaxed but coiled—like a blade in its sheath waiting for a hand to draw it.

  Seconds stretched. Nothing moved.

  Then the shadows shifted.

  Slowly, a figure unraveled from the dark. First a shape, then limbs, then the slithering outline of a cloak catching the dim green glow. A humanoid silhouette stepped forward, absorbing light rather than reflecting it, a creature carved from void and violence.

  One gloved hand brushed the cold surface of the tank as though in idle curiosity. The face remained obscured behind a black, featureless mask—smooth, empty, unreadable. But when the figure lifted its head, turning toward him, light grazed its right side.

  A single red eye burned through the dark.

  A dying star. A hunger. A warning.

  It fixed on him.

  Akio met its gaze from behind the featureless white hound mask. Recognition sparked instantly, cutting through calculation with an icy edge of inevitability. They had anticipated this possibility. Prepared for it in quiet contingency plans. Now it was no longer theory.

  The Hollow had returned.

  Akio watched as the Hollow slowly lowered its hand from the chamber wall, shadows clinging to its movements like oil. A breath later, twin blades materialized in its grasp, curving wickedly like carved fangs. Their handles were joined by a chain that seemed to stretch into darkness itself, disappearing past where logic said they should end. The weapon hung loose but ready—like it existed in a state of permanent threat.

  Akio’s eyes narrowed, analysis snapping into place before the moment finished unfolding.

  Not the scimitar from before.

  This weapon was smaller and lighter. Dual-wielded. Faster. Chain blades meant greater reach, greater unpredictability. They added an entirely different layer of danger.

  He shifted his stance minutely, weapon angled to strike, the pale blue tracing along its edge steady as his heartbeat.

  Across the chamber, the Hollow stared back. Assessing him with the same predatory calculation. Its lone red eye burned with a cold, feral intelligence he had never underestimated.

  Then Akio felt a displacement of air behind his opponent—soundless, effortless—as Gabriel dropped into the chamber.

  The Hollow didn’t react, but there was a subtle shift in its posture—the faint, tensioned awareness of a third presence entering the equation.

  For a long moment, the three of them remained frozen in perfect balance. A triangle of stillness. Breathless tension suspended like an arrow waiting for release.

  The story has been taken without consent; if you see it on Amazon, report the incident.

  Then—

  The Hollow’s eye widened imperceptibly.

  Akio moved first.

  He shot forward and his blade met the Hollow’s strike in a burst of sparks. Akio spun the blade in a fluid arc, striking from a secondary angle before the Hollow had fully recovered.

  But the Hollow moved with impossible reflexes, slipping past the slash and retaliating with an overhead strike—

  Gabriel was already there, scythe carving through the space with a lethal arc that forced the Hollow to pivot sideways, momentum snapping it into a backward leap.

  Akio slid into the landing zone before the Hollow fully touched down, blade already aimed for the throat. Gabriel mirrored him from the opposite side, closing in with perfect timing—a pincer, clean and lethal.

  Then the temperature dropped. A cold shift in the air hit him like a blade to the spine.

  Akio aborted the strike instantly, instincts flaring so violently his nerves sparked. He pushed off the ground and vaulted back just as a blast of corrupt energy erupted from the Hollow.

  He landed lightly at the chamber’s edge, breath steady but senses on high alert as the familiar, sickening twist of the M.A.W. bled through the air. The very architecture groaned in response.

  Across from him, the Hollow rose.

  Black fire ignited along the edges of its twin blades, thin and deadly, and the chains coiled around it like living serpents infused with the same ruinous energy. M.A.W. ran across the links in pulsing waves.

  It was getting serious now.

  Akio adjusted his grip, shoulders loosening in preparation as he began to slowly circle his opponent. Pale blue constructs sparked into existence behind him, data-light feathers spiraling outward in a widening arc.

  Across the chamber, Gabriel twirled his scythe and mirrored the motion, red cards flared into being and slipped into the same rotational current as if drawn by an invisible gravitational pull.

  A dome of floating constructs formed around the chamber in a seamless sweep, pale blue and crimson weaving together into a rotating barrier of sharpened intent. Together, they created a shifting hemisphere of pressure and prediction, sealing off every exit, every angle.

  The fight resumed.

  The Hollow fought like a creature born from violence itself—silent, predatory, every movement carrying an intent to kill. Chains lashed around its shifting silhouette, blades laced with M.A.W. corruption that pulsed like malignant veins. Every strike it landed sent corruption splintering across the environment, metal wilting under the corrosive spread.

  Akio and Gabriel never let it touch their weapons. Their strikes were too swift; their dodges too precise. In the narrow spaces between attacks, they switched positions seamlessly—baiting, forcing angles, driving the Hollow back with a rhythm sharpened over years.

  Evenly matched. For now.

  But Akio could feel it: the Hollow was beginning to slow. Its slashes came a fraction later, its evasions a fraction shorter. The pressure was working.

  They were wearing it down.

  Suddenly the Hollow abruptly disengaged. It pushed off Akio with explosive force, flipping backward through the air before skidding across the chamber floor. Metal screeched beneath its claws as it crouched low—one palm pressed flat against the ground.

  Akio landed lightly, boots barely making a sound. His senses sharpened instantly.

  The floor trembled.

  He glanced down just as darkened fragments of metal and viscous black oil seeped upward through the grated panels. The pieces shook, rattled, then surged toward the Hollow as if pulled by an invisible gravitational field. They gathered, fused, twisted—taking form faster than the eye could track.

  Within seconds, a massive centipede-shaped Anomaly towered behind the Hollow. Its body scraped the chamber walls—rows on rows of rotating saw teeth grinding together with a metallic shriek. Bright red sensors along its head flared erratically, casting violent streaks of crimson light.

  The temperature dropped, and Akio felt the certainty settle into his bones.

  We can’t let that thing reach the surface.

  His feathers broke away from the dome and shot outward in a burst of pale-blue light. They streaked across the chamber, detonating on impact in blinding flashes that momentarily disoriented the Anomaly. The creature recoiled, metal plates vibrating violently.

  Akio slid beneath a descending blade of its segmented body and sliced cleanly across the exposed joints, sparks scattering in a radiant arc. The Anomaly lurched sideways with a mechanical screech, attempting to correct its balance—

  —but Gabriel was faster.

  Scarlet cards rained from above like burning meteors, shredding through the opposite limbs in an instant. Severed metal crashed to the ground as the Anomaly toppled.

  That was the opening Akio needed.

  In one fluid motion, he vaulted over its collapsing body and drove his blade straight into the exposed central core, a single blinding pulse tearing through the chamber as the Anomaly detonated. Fractured metal rained across the floor.

  Silence swallowed the chamber.

  Akio landed lightly, scanning the destruction with cold precision.

  The Hollow was gone.

  He straightened, breathing steady. His gaze tracked the shadows for movement—listening, calculating—but there was nothing. Only the scorch marks where the creature had stood.

  Off to the side, Gabriel stepped over twisted metal, his cloak flicking behind him as he examined the wreckage. His voice crackled softly through the comms.

  “Its fighting style changed.”

  Akio nodded once, eyes narrowing. “Cleaner. Faster. And the M.A.W. usage…” He exhaled quietly. “More deliberate and concentrated. Its refining it.”

  Gabriel hummed, the sound low and serious. “It’s way more efficient. That thing isn’t just adapting—it’s getting smarter.”

  Another hush settled between them. Akio stood amid the wreckage, blade lowered but not relaxed, breath steady as his mind replayed every instant of the fight in stark clarity.

  Before, years ago, the Hollow wielded the M.A.W. like an uncontrolled storm. It had let corruption swallow its entire form, its weapon dripping with volatile darkness that crawled and writhed like a living parasite.

  But now…

  Now the M.A.W. threaded along its blades in thin, precise lacing—controlled, deliberate, almost elegant. A weaponized filament instead of a flood. Subtle enough to evade the eye, lethal enough to kill before a countermeasure even formed.

  The change unsettled him more than he wanted to admit. It no longer moved like an unknowable creature.

  It moved like a person.

  Before the thought could settle, a soft, sharp beep cut through the comms—crisp, unceremonious, utterly out of place amid the carnage.

  Akio blinked.

  The timer. Ten minutes is up.

  A brief, indescribable beat of dread hit him—not enemy related, not tactical. Something far worse.

  Aira.

  He had completely, catastrophically forgotten he was on a timer. If he stayed even a minute longer—

  She is going to hound me for days.

  “…I have to go,” he said, deadpan but resigned.

  Through the dim static, Gabriel’s voice slipped in, amused in that unmistakable way of his. “Don’t worry. I’ll handle the cleanup. Tell her friend I say hi.”

  Akio’s mouth curved—just slightly—into a fond, exasperated smile. “Thanks. And… I will.”

  He sheathed his blade, stepped backward once, then vaulted up onto the nearest ledge in a single silent leap. His movements resumed their usual efficiency—swift, clean, cutting through ruined corridors with practiced ease as he ascended toward the exit.

  Even as he ran, his mind didn’t still.

  Three years without a sighting. And in that time, the Hollow had not only survived—it had adapted. Refined. Learned. That alone carried more implications than he could process in a single sprint, but they would unravel that mystery later. For now, there was a different mission.

  Get out. Get home. Get changed.

  And—somehow—arrive on time to meet his sister’s long-lost best friend.

  Akio moved with new purpose, cloak cutting through the stale air as he vanished into the upper corridors, already planning three routes and a justification that would hopefully save him from Aira’s wrath.
