The fusion with Amy Mori had elevated Riku to a celestial force.
His strikes were no longer just fast, they bent space. His light was not just radiant, it was divine.
Every move he made tore through Shiki's blood constructs, shattered his golems, and pierced his defences.
Riku soared above the battlefield, wings of light trailing behind him like comets. With a cry that echoed across dimensions, he unleashed a devastating combo:
Tengu Light Spiral Barrage, A fusion of slashes, punches, and light bullets, all spinning in a vortex of radiant fury.
It crashed into Shiki like a supernova, sending him hurtling through a data tower that collapsed in a cascade of sparks.
Shiki lay in the rubble, his blood aura flickering, his body torn and scorched.
Riku hovered above, glowing like a god. "It's over," Riku declared, his voice layered with Amy Mori's spirit.
But then… the blood moved. The ground beneath Shiki liquefied into a pool of crimson, and from it, tendrils rose, twisting, writhing, whispering.
Shiki's body was lifted by the blood itself, his wounds sealing, his eyes burning brighter than ever.
"You've pushed me to the edge," Shiki hissed, his voice now distorted, ancient. "But I am far from over."
Final Vampire Surge: Blood Domain Unleashed The entire facility shifted. The walls bled. The sky turned red.
Shiki had activated his Blood Domain, a pocket dimension where he controlled every molecule of blood, including the ones inside Riku.
Riku winced as his body began to resist him, the blood within trying to betray him.
But he gritted his teeth. "Amy… we're not done yet."
The light around him flared, purifying the corruption, and he summoned a new move, one he had never used before.
Tengu Light Purge, A radiant pulse that cleansed the battlefield, pushing back the Blood Domain and restoring clarity to the corrupted realm.
The two warriors stood again, battered but unyielding.
With a blinding arc of his Tengu Light Slash Spiral, Riku surged forward like a comet, his blade trailing divine energy. Shiki raised his blood sword to block, but he was a fraction too slow.
A burst of radiant light exploded across the battlefield as Riku's blade cleaved through Shiki's right arm, severing it cleanly at the shoulder.
The limb fell to the ground, dissolving into a pool of blood that hissed and steamed under the purity of Riku's light.
Shiki staggered back, eyes wide in disbelief. His regeneration, once instant and unstoppable, was faltering.
"No…" he growled, clutching the wound. "This… shouldn't be possible."
The blood around him writhed, trying to reform the missing limb, but Riku's light had done more than cut, it had purified.
The wound was resisting regeneration, sealed by celestial energy that even Shiki's True Vampire Form could not override.
Riku hovered above, wings of light spread wide, his mask glowing with Amy Mori's spirit. "Your darkness is strong, Shiki… but it's not invincible."
Shiki dropped to one knee, blood dripping, his breath ragged. The facility pulsed around them, reacting to the shift in power. The Blood Domain flickered, unstable.
But Shiki was not finished.
He slammed his remaining hand into the ground, summoning a surge of blood from the facility's core. "If I cannot regenerate… I will evolve."
Blood Core Awakening. Shiki began drawing power directly from the Cyber Facility's corrupted systems, fusing blood with raw data, forming a new, unstable hybrid energy.
His body began to mutate, veins glowing with digital red, his aura warping into something unnatural.
Riku narrowed his eyes. "You're tearing the dimension apart."
Shiki grinned through the pain. "Then let it break. I will rebuild it in my image."
Riku hovered midair, his celestial wings flickering. The fusion with Amy Mori had pushed him beyond his limits, but now… cracks were forming.
His breathing grew heavy. The glow around him dimmed.
The Tengu Light Purge had weakened Shiki's Blood Domain, but it had not destroyed it. And now, Shiki's Blood Core Awakening was taking full effect.
Digital Blood Surge, Shiki's mutated form pulsed with hybrid energy, blood fused with corrupted code.
He raised his remaining arm, and from the facility's walls, tendrils of blood-data lashed out, striking Riku like whips of venom.
Riku cried out, his body convulsing as the tendrils tried to override his light. His sword flickered. His wings faltered.
"No… not yet…" he gasped, clutching his chest as the blood tried to invade his core.
Shiki rose from the rubble, his form monstrous, his voice layered with digital distortion. "You shine bright, Riku… but even stars burn out."
He launched forward, faster than before, his blood wings slicing through the air.
Riku raised his blade to block, but the impact sent him crashing into a data pillar, shattering it in a burst of corrupted light.
***
The facility's alarms blared. Systems failed. The dimension itself was beginning to collapse.
Riku struggled to rise, his body trembling. Amy Mori's spirit flickered within him, whispering: "You must endure. The light is not gone, it is waiting."
The corrupted dimension trembled as Shiki's Blood Core surged, threatening to consume everything. Riku, battered and dimming, stood his ground.
His celestial Armor cracked, his wings flickering. But within him, Amy Mori's spirit whispered one final truth:
"The light isn't just power. Its purpose."
Riku's grip tightened on his sword. With a roar that echoed across the collapsing realm, he launched forward, channelling every ounce of his fused strength into one final strike:
Tengu Light Judgment, A divine slash that cut through blood, code, and corruption alike.
It pierced Shiki's mutated chest, severing the Blood Core and shattering his domain.
Shiki gasped, his body unravelling into crimson mist. "No… I am eternal…"
But the light consumed him.
Shiki Goldheart, Destroyed.
The Cyber Facility stilled. The blood receded. The data streams began to heal.
Riku collapsed to one knee, his sword fading, his Armor dissolving into stardust.
The Tengu Mask lifted from his face, floating gently before him. From it, Amy Mori emerged, her spectral form glowing softly, her eyes filled with pride.
She stepped forward and wrapped her arms around Riku, her embrace warm and grounding.
"You did it," she whispered. "You helped Paulo save many worlds."
Riku closed his eyes, exhausted but at peace. "We did it."
But peace was short-lived.
His cosmic senses flared. From the shadows of the corrupted data vaults, movement stirred. One by one, figures emerged, cloaked in blood mist, eyes glowing red.
100 Lesser Vampires, Shiki's hidden legion, remnants of his twisted empire.
Riku narrowed his eyes. "So, this was your insurance, Shiki…"
But these vampires were nothing like their fallen master. They lacked his power, his cunning, his immortality. They were echoes, dangerous in numbers, but fragile in spirit.
Riku gripped his light sword, now humming with quiet fury. "I don't need Amy for this."
Light Blitz Mode Activated. Riku surged forward, a blur of brilliance.
Each slash of his blade disintegrated vampires into dust. Each punch sent shockwaves through their ranks. Light bullets rained from above, precise, and unrelenting.
***
The facility became a battlefield of radiant justice. Vampires tried to swarm, but Riku's speed was unmatched.
He weaved through them like lightning, cutting down dozens in seconds.
Light Slash Barrage, A sweeping arc of destruction cleared entire corridors.
Into a Light Punch Barrage and Light Bullets Barrage, A combo that turned the tide into a massacre.
Within minutes, the last vampire fell, disintegrating into a whisper of blood.
Riku stood alone once more, his sword fading, his Armor dimming. The Cyber Facility was quiet. Cleansed.
He walked to the Tengu Mask, now resting peacefully on a pedestal of light. Amy Mori's spirit shimmered faintly within.
"It's done," Riku whispered. "They're all gone." And for the first time in ages, the dimension exhaled.
