đ Midnight â Dimensional Rift, Border of Kuoh Town
A crack in the sky.
It appeared without warning, a shimmering tear in space that bled violet lightning and roaring winds. Hidden from mortal eyes, this rift pulsed at the edge of Kuoh Town's barrierâunstable, volatile, and unnatural.
Kaizen stood at the edge of it, his coat fluttering violently in the storm of energies. His eyes narrowed as his Gearflow Vision mapped the rift's frequencies in real time, calculating dozens of variables per second.
"This... isn't natural," he murmured. "It's not just a tearâit's a message."
Behind him, Akeno and Kiba arrived, their auras tightly coiled in readiness. Akeno's fingers crackled with restrained electricity, while Kiba's hand hovered near the hilt of his sword.
"Who could've done this?" Kiba asked, his voice tense.
Kaizen turned, his gaze serious. "Someone who wants to bypass this world's protections. Someone who knows how to thread between realities."
"Another like you?" Akeno asked, stepping closer, her expression unreadable.
Kaizen hesitated. "Possibly. But if so, they're not friendly."
The rift pulsed again, and a shape emergedâa shadowy figure in a long cloak, eyes glowing a deep crimson. Kaizen's pupils contracted. That energy signature... it matched the one from the ruined fragments of another multiverse.
A voice echoed from the figureâdistorted, haunting.
> "You left the door open, Kaizen."

đ Earlier â Occult Research Club Room
That afternoon, the mood had been lighter. The club members had gathered for their usual strategy discussion. Rias sat at the head of the table, flanked by Akeno and Koneko, with Kaizen standing behind her, arms folded.
"We've intercepted transmissions from the Fallen Angels," Rias said, spreading a glowing map over the table. "They're regrouping. Azazel might not be the only one aware of our presence here."
"And what about that strange energy signature we detected near the temple ruins last night?" asked Issei, scratching his head.
Kaizen stepped forward. "That wasn't from this world either. I cross-referenced it with multiversal patterns. It matches something from a dead timeline. Someone is opening breaches."
The group tensed. Even Rias's composed demeanor wavered slightly.
"Do we know what they want?" Koneko asked.
Kaizen's voice was low. "They're after me."
Akeno turned, eyes narrowing. "Because of your ability?"
He nodded. "More specifically... my core. If they get it, they can map all the realms I've been toâand open them permanently."
Rias stood. "Then we protect you. Together."
Kaizen looked around the roomâIssei clenching his fists, Kiba nodding resolutely, Akeno offering a small but fierce smile, and Koneko staring at him with unexpected warmth.
Maybe, just maybe... this place was becoming more than just a mission.

đ¤ Later That Evening â Church Ruins
Kaizen stood before the remnants of the old church where Issei had once died. The air smelled of ash and time. He placed a hand on a scorched beam, memories flooding backâof a girl's scream, of light exploding, of blood on sacred stone.
Suddenly, footsteps echoed behind him. He turnedâXenovia and Irina, the exorcists, approached, their blades sheathed but their expressions guarded.
"You're Kaizen," Xenovia said. "The anomaly."
Kaizen chuckled. "I've been called worse."
Irina eyed him carefully. "We were told to watch you. But Michael says to observe, not interfere."
"Wise of him," Kaizen replied. "This war... is bigger than you think."
Xenovia crossed her arms. "Then show us."
Kaizen raised a hand. A projection bloomed into the air, showing collapsing timelines, alternate versions of Kuoh, twisted by beings known as the Ashborne. Entire worlds consumed by one name: Nullshade.
Irina paled. "That'sâŚ"
"The enemy that's hunting me," Kaizen finished. "And they won't stop at me. They want everything."

đď¸ Back to Midnight â Dimensional Rift
The cloaked figure stepped forward. "You know me, Kaizen. Or you used to."
Kaizen's mind reeled. That voiceâit wasn't just familiar. It was his own.
The cloak dropped.
The figure was Kaizen.
Or rather, another Kaizenâscarred, corrupted, glowing with chaotic power. His left arm was mechanical, infused with red lightning. His eyes shimmered with a void-like gleam.
"I am what you abandoned," the dark Kaizen said. "I am Nullshade."
---
đŠď¸ Midnight â Dimensional Rift (Continued)
Kaizen stared at his dark reflectionâNullshadeâwhose presence twisted the air with each breath. Lightning from the rift lashed out violently, echoing the chaos that clung to his multiversal counterpart like a second skin.
Issei, Akeno, and Kiba formed a defensive line behind Kaizen.
"Is that⌠really you?" Issei asked, disbelief in his voice.
"No," Kaizen muttered. "That's what I could've become."
Nullshade raised his arm, and the corrupted aura of his Gearflow erupted around him, black and crimson circuits flaring like a neural web gone rogue. "You abandoned countless timelines. Left them to rot in collapse because you chose to move forward. I chose to fix them."
"By breaking into this one?" Kaizen's voice was calm but firm. "By hunting me down?"
"They call it corruption. I call it clarity," Nullshade hissed. "You were too weak to do what was necessary."
Kaizen's fists clenched. Behind him, Akeno's aura surged with lightning.
"Permission to strike?" she asked, her voice controlled but furious.
"Not yet," Kaizen answered. "This is my fight."
Nullshade laughed, the sound distorted like a broken radio. "Oh, no. This is everyone's fight now."
He slammed his corrupted palm into the ground. The rift expandedâand from it emerged creatures born of fractured timelines. Echoes of fallen warriors, distorted angels, and warped devilsâAshborne. Shadow-born anomalies that fed on collapsing reality.
Kiba drew his sword. "We're surrounded."
"Split formation!" Kaizen commanded. "Akeno, support Kiba and Issei! I'll handle him!"
The battlefield exploded into chaos.

âď¸ Battle Sequence â Riftfront
The Ashborne chargedâsilent, fast, and monstrous. Kiba blurred forward with holy demonic sword in hand, carving a path through twisted versions of familiar foes. Akeno floated above the ground, calling down lightning strikes in perfect arcs. Her magic glowed brighter than ever before.
Issei powered up his Boosted Gear, each shout of "Boost!" stacking raw force behind his gauntlet.
Kaizen and Nullshade clashed at the rift's center.
Gearflow versus corrupted Gearflow.
Their strikes were a storm of shimmering energy, flickering images of alternate realities flashing around them as they moved. Each punch and block echoed across the multiverse.
"You think you're saving them," Kaizen growled, parrying a strike, "but you're erasing free will!"
"I'm giving them structure! A world without suffering, without failureâwhere only strength survives!" Nullshade bellowed, sending a shockwave across the battlefield.
Kaizen rolled to the side, panting. Blood dripped from a shallow cut across his cheek.
His AI flickered.
ăCore integrity at 89%. Synchronization stable. Suggest recalibrating auxiliary memory nodes.ă
"No time," Kaizen whispered. "Overclock Gearflow."
His aura flaredâsilver and blue circuits dancing violently across his skin. Time slowed. He saw Nullshade's next move before it happened, pivoting to strike under his corrupted clone's guard.
His punch landedâstraight into Nullshade's chest, cracking his armor and sending him flying.

đ Elsewhere on the Battlefield
Issei shouted, "Dragon Shot!" blasting apart a shadowborn with sheer brute force.
Kiba covered his flank, slashing down another with a spinning flourish. "They just keep coming!"
Akeno's wings flared, lightning forming an arc between her hands. "Then we'll keep sending them back!"
Her power surged, and in a brilliant flash, she wiped out the entire right flank of Ashborne invaders.
Kaizen, breathing hard, leapt in front of them just as Nullshade returned, his damaged frame steaming and crackling.
"You're stronger than I expected," Nullshade said, smirking. "But so am I."
He pulled out a jagged blade forged from corrupted timeâChrono Reaper. It pulsed with dark multiversal energy.
Kaizen reached inside his cloak and drew a glowing crystal daggerâthe Echo Fang, gifted to him by a protector deity from another reality.
"This ends now," Kaizen said, his voice resolute.
---
đ Final Duel â Center of the Rift
Time itself fractured around them as the two Kaizens foughtâslashing through echoes of infinite possibilities.
One strike shattered a version of Kuoh Town where devils ruled the skies. Another tore open a glimpse of a world where Kaizen had never left his original home.
Each blow carried the weight of a different choice.
Nullshade moved with anger, with purpose twisted into obsession.
Kaizen moved with clarityâand conviction.
Their blades locked.
"You could've been me," Nullshade snarled. "You were me!"
Kaizen's eyes burned. "But I chose to grow. I chose people."
With a final roar, Kaizen activated his core's hidden functionâSingularity Pulse. His dagger exploded in light, severing the bond between Nullshade and the rift.
The corrupted double screamed as the light consumed him, and the rift collapsed in on itself, imploding with a deafening boom.
The battlefield fell silent.

đ Post-Battle â Kuoh Academy Roof
Later that night, the ORC members sat in silence on the rooftop.
The moon shone peacefully again, the stars returning to their proper order.
Issei broke the silence. "That was⌠not normal."
Kiba nodded. "We just fought ghosts of the future."
Akeno looked at Kaizen. "What happens now?"
Kaizen, arms folded, stared at the horizon. "Now we prepare. That was only one of them. Nullshade was just the first to breach this world."
Rias appeared behind them, her presence regal and calm.
"You've proven yourself again, Kaizen," she said. "And I think it's time we move forward... together."
Kaizen gave a slow nod.
The war wasn't over.
But tonight, they'd earned peace.
