The horizon above the Jaku General Hospital didn't look like a sky anymore. To Kenji Mizunashi, it looked like a Rendering Error. The air was thick with the scent of ozone and the "Digital Static" of a hundred thousand Quirks activating at once. This was the Paranormal Liberation War, the moment the "Main Quest" shifted from a school simulation into a total System collapse.
Kenji stood at the vanguard of the System Raiders—a specialized unit he had hand-picked from Class 1-A and 1-B. Beside him stood Bakugo, Shoto, Midoriya, and Tokoyami, each of them equipped with "System-Synced" gear Kenji had crafted using Zonai Ultrahand and Mass Effect Omni-Tools.
"Listen up," Kenji's voice resonated, now a perfect harmonic blend of human warmth and machine precision. "This isn't a skirmish. All For One has initiated a World-Overwrite. He's trying to merge the Quirk Singularity with the planet's 'Source Code.' If he succeeds, there's no 'Respawn.' There's only 'Deletion'."
Part I: The Siege of Jaku
The signal was given. Endeavor and the Pro Heroes launched the frontal assault, but Kenji's team had a different objective: The Central Server. Deep beneath the hospital, Dr. Garaki was finalizing the "Upload" of Tomura Shigaraki's new body.
"Raiders, initiate Blink-Sequence!" Kenji commanded.
Using the Destiny: Void-Walker logic merged with Nightcrawler data, Kenji didn't just run; he folded the space between the hospital entrance and the laboratory. In a single, flickering second, the System Raiders bypassed the frontline Nomu and appeared in the heart of the "Bio-Computing" lab.
[WARNING: HIGH-LEVEL ENTITY DETECTED]
[TARGET: TOMURA SHIGARAKI (99% COMPLETE)]
Shigaraki sat in a vat of "Structure Gel," his eyes snapping open. They weren't the eyes of a man anymore; they were a Global Malware.
"Mizunashi..." Shigaraki's voice echoed through the room without his mouth moving. "You're too late. The 'User Agreement' has been signed. I am the Admin now."
Part II: The Multiversal Onslaught
The vat shattered. Shigaraki didn't touch the ground; he floated, a dark aura of Decay-Code radiating from him. Every tile he touched didn't just crumble; it turned into "Null Data"—a black void where nothing could exist.
"Raiders! Full-Buffs!" Kenji roared.
Kenji initiated the Omni-Build: The Final Fantasy Limit Break.
He summoned the Exalted Blade (Warframe) and infused it with Elden Ring's Destined Death. He lunged at Shigaraki, the two meeting in a collision of gold and black energy that shook the very foundations of the mountain.
"Bakugo! Use the Doom-Eternal: Grenade Logic! Overwhelm his 'Regeneration Frames'!"
"Shoto! Lifestream-Freeze! Lock his 'Source Code' in place!"
The battle was a sensory overload of high-level gameplay. Bakugo moved at Mach speeds, his explosions now leaving "Lingering Burn" status effects that prevented Shigaraki's cells from knitting. Shoto unleashed a massive wave of ice that didn't just freeze; it Transmuted Shigaraki's Decay-aura into harmless prismatic crystals.
Part III: The Corruption of the World
But Shigaraki wasn't alone. Deep within his mind, the All For One Virus took control. The villain's body expanded, sprouting thousands of hands made of "Corrupted Data."
"You think you're the only one who can 'Mod' reality, Kenji?" All For One's voice boomed. "I've been stealing 'Code' for a century. I've eaten the souls of the 'Original Players'!"
All For One unleashed a System-Wide Decay. The hospital began to "Clip" into the ground. The sky turned a deep, bleeding red. The "Quirk Singularity" was happening—reality was becoming too heavy for the "Engine" of the world to support.
[SYSTEM CRITICAL: FRAME-RATE DROPPING...]
[WORLD INTEGRITY: 42%]
Kenji felt his own "Master Interface" straining. He saw Midoriya struggling, the One For All energy being "Leached" by Shigaraki's parasitic code.
"I have to do it," Kenji whispered. "I have to Format the Planet."
Part IV: The Final Dive – The Genesis Protocol
Kenji closed his eyes while parrying a mountain-sized hand of decay. He entered his Fourteenth and Final Dive: The Genesis Protocol.
This wasn't a game. It was the Developer's Tool-Kit. He merged the creation-logic of Minecraft and Stellaris with the soul-binding power of Elden Ring.
He didn't fight All For One. He Recoded the environment.
Kenji raised his hand, and the "Null Data" Shigaraki had created began to transform. The black void turned into Golden Ley Lines. He was "Attaching" the broken pieces of reality back together using Ultrahand.
"All For One!" Kenji's voice was now the voice of the World itself. "You are an 'Unauthorized User'! Your 'Account' is being Terminated!"
Kenji unleashed the Limit Break: The Final Patch.
He manifested a staff made of every "Game" he had ever played. The Hokuto Shinken pressure points, the Wukong strength, the Mass Effect Biotics, and the Cyberpunk hacks all converged into a single point of infinite density.
He struck Shigaraki in the chest.
"FORCE-QUIT."
Part V: The Deletion of Evil
The impact was silent. A wave of white light washed over the entire Jaku city, then the country, then the world. It wasn't an explosion; it was a Deep-Clean.
Every "Nomu" simply turned back into the "Data" they were made of—becoming flowers and trees. The "Decay" was deleted. The "Corruption" was scrubbed from the atmosphere.
Inside the mental "Server" of All For One, Kenji faced the old villain one last time.
"You can't delete me," All For One hissed, his form flickering like a dying candle. "I am the history of this world!"
"No," Kenji said, his hand glowing with the Lifestream. "You're just an old 'Save File' that's been corrupted for too long. It's time for a New Game."
Kenji touched the villain's forehead. The black ooze of All For One dissolved into golden sparks. The "Virus" was finally, permanently, Deleted.
Aftermath: The End of the Tutorial
Kenji woke up on the grass of the mountain. The sun was rising, a true, natural sun that didn't have a "Visual Glitch" in sight.
Beside him, Midoriya, Bakugo, and Shoto were breathing heavily, their Quirks intact but their "System-Gear" dissolved. They were just boys again.
Kenji looked at his own hands. His silver hair had returned to its natural dark color. His Focus HUD was gone. The "System" was silent.
"Is it... over?" Midoriya asked, looking at the peaceful horizon.
"The 'Main Quest' is," Kenji said, a soft smile on his face. "All For One is gone. The 'Corruption' is deleted. The 'Quirk Singularity' has been patched into a 'Evolutionary Update'."
"Then what now?" Bakugo asked, looking at Kenji. "Without your 'Gamer' powers, you're just a normal nerd."
Kenji stood up. He felt the wind on his skin, the weight of his own body, and the warmth of his friends. He didn't have a HUD, but he could still see the beauty of the world.
"Now," Kenji said, "we play the 'Post-Game.' And I hear the 'Free-Roam' in this world is incredible."
