Before the screams, before the ash-filled skies, before the cities were reduced to bone and steel there was peace.
And in that peace… lived a boy with eyes sharp enough to cut through lies. Arashi Kuroda. Only 17, yet hailed as the brightest mind of the Neo-Scientific Era. He wasn't just a student he was a prototype architect for the "Project Heaven Chain," a top-secret mission designed to connect alternate dimensions through Qi-energy stabilization.
He wasn't born for battle. He was born to build. In the capital city of Neo-Yokai, surrounded by skybridges, synthetic gardens, and towers that touched the clouds, Arashi coded reality while his peers struggled with simulations. But perfection breeds enemies.
One day, during a system stress test inside Sector 7's lab, alarms blared. "Energy Surge Detected Dimensional Barrier Breach!"
He turned to the screen watching as a black fissure spread across the dimensional map like cracked glass. "That's not supposed to happen..." By the time the emergency crew arrived, it was too late.
The rift had opened. And something stepped through. The rift wasn't just a tear in space. It was a doorway. From it poured a plague of horrors zombie-like beings, fused with ancient curses and alien technology, unlike anything in Earth's database.
Some were slow… others screamed. Some walked upright… others crawled upside down on walls. But all of them… were hungry. The Fall began that night.
Governments collapsed in 48 hours. Satellites went dark. The World Defense Protocols failed. And the cities that once gleamed turned into slaughterhouses.
Arashi ran.
From labs, from guilt, from the knowledge that he had caused this.
He tried to warn, to fix, to re-stabilize the system but every time he recalibrated, another rift opened somewhere else. The dead weren't coming from one world.
They were leaking in from dozens. His family was among the first to fall his mother infected, father torn apart while shielding him.
That night, Arashi didn't cry. He didn't scream. He just stared at the stars, burning through the smoke-choked sky. "If this is my curse… then let me carry it alone."
Years passed in shadows. Arashi became something else half genius, half ghost.
He joined rogue squads, fought beside death-hardened survivors, fused broken tech with forbidden Qi techniques from ancient scrolls left behind by monks and hackers alike. And finally when all hope seemed gone…The Core Theory appeared in a dream. "What if the virus wasn't just spreading… but seeking something?"
He returned to his destroyed lab, reactivated the Heaven Chain system, and tried one final time to stop the multiverse infection. He initiated a risky reverse-pulse through the corrupted Qi-threads, hoping to seal the rift once and for all.
System: 'Dimension Lock Initiated…'
But something pushed back.A presence. A voice. "Your soul doesn't belong here, Arashi Kuroda."
The screen cracked. His vision blurred.
The last thing he saw was his own body breaking apart and the world exploding in a flash of white light.
"System Integration: Success."
"Host Transferred to Parallel Stream: Earth-3490."
"Welcome back, Arashi Kuroda. Reincarnation Complete."
