The wind howled, pulling at the heavy crimson leather of Ace's Demon Hunter's Coat as he stood at the edge of the rooftop. The dying sun painted the sky in violent streaks of bruised orange and deep purple, casting long, warped shadows across the concrete.
"Let's see what's making that noise," Ace said, the wind carrying his words away.
He raised the bone-white Hollow Mask and snapped it back over his face.
Pop.
The vacuum seal hissed. In the pitch-black labyrinth of the lower floor, the mask had forced his vision into a dichromatic silver-and-blue map. But here, bathed in the bleeding light of the sunset, the optic lore adjusted. The vivid colors of the dying day rushed back into his eyes. The mask didn't blind him to the natural world; it simply augmented it. A subtle, high-contrast HUD overlaid his normal vision, painting faint, shimmering silver halos around heat signatures and spatial anomalies.
Through this new predatory lens, he scanned the roof. It was a nightmare ecosystem—a jungle of bioluminescent ferns and mutated moss, set against the jagged silhouette of the Seattle skyline. In the center, where a luxury infinity pool once sat, the water had been replaced by a thick, viscous black tar.
Rising from the center of that sludge was a giant, violet bulb-shaped plant. It pulsed with a rhythmic, sickening light, its massive roots tangled deep into the building's concrete spine.
Thrum... Thrum... Thrum...
The heartbeat was deafening out here.
Ace swept the perimeter, moving with the Silent Tread of his Waraji Striders. He used the massive HVAC cooling towers as cover, the Hollow Instinct highlighting his path through the blind spots in faint silver. He rounded a rusted exhaust duct and froze.
He came face-to-face with a creature he'd never seen before—a humanoid variant, but its throat was swollen into a massive, glowing, translucent sac.
It saw him. Its jaw unhinged.
Ace moved with Shunpo speed. He blurred forward, his reinforced tactical glove slamming into the thing's throat to crush the sound, but he was a fraction of a second too late.
SCREEEEE—!
A jagged, piercing note tore through the air, vibrating the very concrete beneath his feet.
The roof responded instantly. The giant bulb in the pool convulsed, splitting open down the center with a wet, visceral tear.
The sheer shock of the grotesque amalgamation of vine and flesh tearing itself out of the plant triggered Ace's raw reflexes. Before his conscious mind even registered the threat, he flared his red coat, drew the twin Ebony & Ivory replicas in a blur, and opened fire in pure surprise.
BANG-BANG-BANG!
The initial shots staggered the emerging mass, but it immediately arched back and retaliated, spitting a massive glob of steaming, acidic slime. Vines erupted from the tar pool like biological harpoons, lashing out to drag him into the center.
Ace moved. He flipped backward, the acid hissing violently as it melted the concrete where he had just stood. Landing cleanly in a low crouch, he instantly drove all his weight into the Waraji Striders. The reinforced steel soles bit into the roof, allowing him to violently redirect his kinetic energy and launch himself forward into a dead sprint. He vaulted off a rusted pipe, sprang off the side of a concrete pillar, and twisted in mid-air—channeling the high-octane acrobatics of a legendary demon hunter—landing perfectly on top of a massive HVAC unit.
He had the high ground. He leveled the twin Arcane pistols and unloaded.
BOOM-BOOM-BOOM!
He emptied both magazines, twenty-four rounds of magically stabilized lead tearing into the center mass of the bulb. The firepower shredded the plant matter into a pulp of violet sap and black ichor.
The bulb slumped heavily against the cracked pool foundation. The vines went completely limp.
Ace stood atop the HVAC unit, smoke curling from the barrels of his guns. He crossed his arms, twirling the pistols around his fingers before snapping them forward into a classic, stylized pose.
"Jackpot," he smirked behind the bone-white mask.
He hit the magazine releases, the empty clips clattering against the metal roof. As he slid fresh magazines into the grips, he paused. He waited for the objective readout. The system notification.
Nothing happened.
The shredded outer layer of the plant suddenly fell away in wet chunks. Out from the gore stepped the true form—a mobile, skeletal variant covered in dense, thorn-like armor. It screeched, charging with terrifying, explosive speed.
The fight instantly escalated into a high-speed, acrobatic blur. Ace dropped from the HVAC unit, his hands moving with impossible fluidity. He holstered Ebony, keeping the white silver of Ivory leveled in his left hand, while his right hand drew the sleek black blade of the Tensa Zangetsu replica.
The creature moved with predatory elegance, leaping from ducts to the edges of the pool. Ace met it head-on, seamlessly weaving Swordmaster and Gunslinger styles. The clash of its bone-blades against his katana sparked brilliantly in the twilight. Ace parried a sweeping strike with Zangetsu, then immediately thrust Ivory forward, firing a point-blank shot into the creature's armored shoulder to break its poise.
He vaulted entirely over the creature's head, firing mid-air, and transitioned into a heavy, spinning slash upon landing. The variant hissed, its thorn-armored hide whistling through the air as it retreated toward the edge of the building.
As Ace fought, a profound realization hit him. He wasn't just swinging a sword or pulling a trigger; he was executing frame-perfect parries and aerial combos he had only ever done on a controller.
The system wasn't just making him faster. When he had Traced the growing collection of anime and gaming weapons in the Armory, he hadn't just copied their physical forms. He had downloaded their histories. He was absorbing the combat reflexes, the lore, and the soul of every legendary character those weapons belonged to. That was why he trained to exhaustion every night—he wasn't building muscle; he was physically processing the downloaded combat experience. His body was mutating—the hair, the eyes, the predatory instincts—to accommodate a soul crammed with the legends of every hero whose weapon he had claimed.
"Don't run," Ace growled, his voice distorted by the mask.
Ace sheathed Tensa Zangetsu with a sharp, echoing click and slammed Ivory back into its holster. He reached over his shoulder, his fingers wrapping around the skeletal crossguard on his back. He drew Rebellion.
The moment the heavy demonic claymore cleared its scabbard, Ace's entire posture shifted. He wasn't just a survivor anymore; he became the Son of Sparda.
The Sylvan-Reaver lunged, crossing its remaining bone-blades to decapitate him. Ace didn't dodge. He planted his feet and swung Rebellion in a massive, one-handed horizontal arc. The collision sounded like a freight train hitting a brick wall. The sheer kinetic weight of the claymore shattered the creature's guard and threw its entire body off balance.
Ace stepped into the opening. He dropped his shoulder, driving the massive blade upward in a vicious, lifting slash that completely defied gravity. The strike caught the variant under the jaw and launched it spinning fifteen feet into the air.
Before the creature even reached the apex of its launch, Ace leaped after it. He met the monster mid-air, unleashing a blistering, stylized flurry of heavy slashes that shredded its thorn-armor into splinters. Hanging suspended in the air, Ace gripped the hilt with both hands, flipping forward to bring the massive claymore crashing down in a brutal, plunging strike.
The monster slammed back into the concrete roof with a cratering impact, tumbling violently toward the edge of the building. It staggered upright, its bark-skin cracked open and leaking black ichor. It let out a desperate, bubbling screech and prepared for a massive, final leaping strike near the roof's ledge.
The time for games was over.
Ace shifted his center of gravity into a low, explosive stance, channeling every bit of kinetic energy from his Striders into a single, forward burst.
"STINGER!"
He rushed forward like a red comet. Rebellion led the way, the massive blade catching the creature square in the chest. The force of the rush was absolute—it carried the monster twenty feet across the concrete, slamming it into a reinforced maintenance wall at the very edge of the skyscraper.
The variant was impaled, pinned to the wall by the screaming skeletal hilt. It thrashed, its bark-skin cracking. Ace didn't give it a chance to recover. In a blur of motion, he drew Tensa Zangetsu in a reverse grip and drove the black blade straight through the creature's skull, executing a flawless, stylish finish.
The Arcane Integration
The creature went still. As the desiccation process began, the system finally chimed.
[CORE PURIFIED]
Source: Tier 4 Alpha Variant (Sylvan-Reaver)
Essence Purified: +25 UP
The black sludge didn't turn into the usual red motes. Instead, a core began to form that was larger and more intense than anything he had seen. It was a deep, shimmering Gold.
Before he had a second to examine it, the golden core burst into a blinding light. It shot forward, slamming into Ace's chest with the force of a physical blow. He staggered back, his heels catching on the very edge of the roof, the wind howling around him. The supernatural energy sank into his skin, turning his veins into lines of molten gold.
A cascade of new UI prompts erupted across his vision.
[WARNING: COMPATIBLE SUPERNATURAL CORE DETECTED]
[Arsenal Matrix Syncing... 100%]
[WARNING: Traced Arsenal items currently integrating into Host Soul.]
Would you like to activate [GENISIS GATE]?
Ace looked down at his hands, the golden light slowly fading into his skin. He finally understood the scope of what he was becoming. The golden core hummed in his blood, waiting to bridge the final gap between his physical body and the mythical armory locked inside his matrix.
Behind the bone-white mask, a predatory grin widened.
"Hell yes."
