Chapter 1: Deceased
The rain hit like needles. Kai Ren crouched behind a tipped delivery scooter, his uniform soaked through. A gash on his ribs pulsed with heat, blood mixing with gutter water. Above Seoul, the sky flickered a flat, digital blue—not lightning. He had watched three strangers dissolve into static in the last hour.
A window of pale light blinked open in his vision, edges jagged, text glitching. "MANIFEST ZERO ACTIVATED. USER STATUS: DECEASED. QUEST: SURVIVE 60 SECONDS." Deceased? Kai pressed harder on his wound; he was still breathing. The system had to be wrong. Then a screech echoed from the alley behind him.
A creature lunged from the shadows—skin pixelated, fingers splitting into black cables. Kai rolled aside, agony flaring through his side. The thing's claws carved through the scooter's frame like wet paper. He grabbed a loose pipe and swung, but the pipe passed through the monster as if it were smoke. The countdown in his head read forty seconds.
"You're not dead," a voice said. Kai spun, pipe raised. A girl stood in a doorway, half her face hidden behind a cracked phone screen held like a mirror. Her school uniform was torn, sneakers melted to her soles. She pointed at his chest. "Your heart's beating. But the system says you're an error."
The creature charged again. Kai threw the pipe, but it sailed through empty air. The girl raised her phone; the screen flashed white. The monster shattered into a burst of pixels, gone. She lowered the device, breathing hard. "Third one today. Battery's at twelve percent. We need underground before the next wave hits."
The countdown hit zero. A new window appeared, clean and sharp. "QUEST COMPLETE. REWARD: TEN MINUTES OF STABILITY. DEBT INCURRED: ONE MEMORY." Something slipped away from Kai—the name of his favorite noodle shop, erased like deleting a file. He grabbed his temples. "What the hell is this?" The girl yanked his arm. "Move! Explain while we run."
They sprinted through backstreets, past abandoned cars with hazard lights still blinking. The blue shimmer above thickened, pressing down like a second sky. Kai's side bled, but the pain was fading into a cold, foreign numbness. He asked between breaths, "Who are you?" She didn't look back. "Sora. I see your glitch. That makes me your only chance."
A subway entrance loomed, sealed with rusted iron gates. Sora pressed a cracked keycard to a hidden panel; the gates screeched open. As they descended, the walls glowed with blue runes. "Safe zone," she said, "for now." A deep rumble shook the tunnel. The lights flickered. A new notification burned red: "SYSTEM ERROR: USER 000 NOT FOUND. PURGE PROTOCOL IN 30 SECONDS."
Kai froze. The system that had just saved him now wanted him erased. Sora's phone screen died to black. She stared at him, eyes wide with something like fear. "I didn't know it would do that. You're not supposed to exist." A timer appeared in his vision, bright and ticking. The tunnel behind them filled with static.
The Price of Minutes
Kai staggered through the flooded underpass, feet sloshing in oily water. Blue window fragments crunched under his boots, each shard glowing faintly before fading. Above him, the city burned in silence—no sirens, no screams, only the hum of dead servers. His chest ached where the delivery truck had crushed him, but the wound was gone. The system prompt flickered: [Manifest Zero: Anomaly detected].
He swiped at the air, but the text only burned brighter. [Quest issued: Cross the Han River bridge before dawn.] The red map cut through the ruined district, and Kai laughed once, a dry rasp. "I died, and you want me to run a marathon?" The interface did not answer.
He kept moving because stopping felt like finality. The underpass opened onto a street of overturned cars and melted storefronts. A man in a security uniform lay half-dissolved into a parked scooter, his body pixelating at the edges. Kai averted his eyes and stepped over a tangle of sparking cables. The quest marker pulsed ahead, drawing him toward the river.
Half a block later, the air thickened. A Changed lurched from behind a bus stop—a woman whose left arm had become a cluster of weeping antennae. Her telescopic pupils tracked him, and Kai froze, then bolted. Antennae lashed out, slicing the air where his neck had been. He dove through a shattered storefront, glass raining across his back.
Inside the dark convenience store, he crouched behind a toppled freezer. [Quest updated: Survive the Changed for two minutes.] A red countdown appeared: 01:59. His fingers found a fallen can of peaches, and he hurled it toward the back door. The Changed crashed after the noise, antennae scraping concrete, and Kai crawled on his belly toward the front.
The countdown hit zero as he reached the street. A chime rang in his skull, soft and almost pleasant: [Quest complete: Survive.] Heat washed through him, knitting the gashes on his shoulder. But the memory of his mother's face peeled away, frame by frame, like old film burning. He gasped and clutched his temples, but the name was gone.
He pressed his back against a cold wall, breathing hard. The system prompt returned, now in green text: [Temporary survival granted: 23 hours, 59 minutes.] Kai stared at the number, then at his shaking hands. He had completed an impossible quest by accident—and paid with a piece of himself. He tried to summon the memory—a kitchen, a laugh, a scar on her wrist—but nothing came.
A soft beep from the interface made him look up. A new line appeared: [Anomaly proximity detected.] He turned toward the alley mouth where a girl stood between two dumpsters. She wore a yellow raincoat and held a crowbar, her eyes fixed on the air beside him, not on his face. "You're not supposed to be here," she said, and Kai replied, "Neither are you," though he didn't know why.
The Name That Slipped
Kai's boots hammered wet concrete as he sprinted through the tunnel, the beam of Sora's flashlight bouncing off shattered tiles. Behind them, the grinding whine of a purge drone faded, but Kai didn't slow. Water dripped from overhead pipes, each drop a cold kiss on his neck. "Left!" Sora hissed, yanking him into a side passage.
A blue system window flared across his vision, its text glitching into unreadable static. [QUEST UPDATED: SURVIVE THE NEXT HOUR.] Kai blinked it away, but the command left a bitter taste. He tried to recall the street where he had died, but the image came up blank. Only the weight of the Manifest Zero interface remained, humming behind his eyes.
They slowed at a steel door recessed into the tunnel wall, its surface scarred and spray-painted with a crude eye. Sora killed the flashlight and pressed her ear to the metal. "Someone's in there," she whispered. "I know this place." Kai flexed his fingers, ready to run again.
Sora knocked twice, then once. The door cracked open, revealing a sliver of warm light and the barrel of a homemade crossbow. "Who the hell are you?" a man's voice growled. "Doyun, it's me—Sora. I've got an error with me." The door swung wider, and an old man with a burn scar down one cheek stepped back.
Doyun's bunker was a narrow room lined with salvaged batteries and stacks of ration bars. He locked the door behind them and studied Kai with bloodshot eyes. Then he held up a cracked system pad, its screen lighting with a red error icon. "You're not just dead," Doyun said. "You're NULL. System reads you as corrupt data."
Doyun set the pad on a crate and crossed his arms. "Purge protocols hunt NULLs first. That's why the drones keep finding you." He tapped the pad, and a map of the surrounding tunnels appeared with one node blinking red. "There's a collapsed server node two blocks north. I can build you a jammer, but I need a data shard from it."
Before Kai could answer, Manifest Zero flashed a new prompt: [QUEST ACCEPTED: FETCH THE DATA SHARD. REWARD: TEMPORARY SURVIVAL.] The words burned white-hot, and Kai felt a familiar hollow ping in his chest. Sora grabbed his arm. "Kai, don't. Every reward eats a memory." He shook her off. "I don't have a choice."
Doyun handed them a cracked flashlight and a length of steel pipe. "Move fast. The node's guard has Changed, but it's slow in the dark." Kai turned to Sora, but her name slipped sideways in his mind. He opened his mouth and said, "Yuna, stay close." Sora's face went pale. "It's getting worse."
They stepped back into the tunnel, the door sealing behind them with a heavy clang. Sora walked a step ahead, her shoulders rigid. "You promised you'd remember me," she said without turning. Kai wanted to answer, but the name wouldn't come. Then the tunnel ahead filled with the slow scrape of claws.
