Zombie Virus In Jujutsu Kaisen

The bridge lights of the 20th ward gleamed like a string of trapped stars, their reflections jittering in the swollen river below. Rain, thin and persistent, smeared the neon into watercolors. From the riverbank, Fushiguro Megumi watched the city breathe-sirens, distant shouts, the low hum of cursed energy like an undercurrent-trying to parse the static. He didn't want chaos. He wanted to find allies, gather information, and keep as many people alive as possible. Tonight the Culling Game felt like a wound that might finally scab; instead, something slick and unseen began to ooze out.

The first sign was subtle. A freshman-level participant-thin, eyes fever-bright-staggered into the abandoned ramen shop where Megumi and a handful of other players had set a temporary base. The kid's veins mapped dark under his skin, and his breath came as if a fist pressed against his throat. When he snarled, the sound wasn't speech. It sliced.

"Get back," Megumi snapped, instinct flaring. He didn't have a plan beyond containment, just reflexes. The others obeyed, weapons raised: simple knives, conjured shikigami claws, and one loner brandishing a hunting rifle like a prayer. The kid's lips curled, and there was no recognition in his gaze-only appetite. That absence of recognition was the wrongest thing Megumi had ever seen.

"He's got an unknown contagion," Nanami said flatly, appearing from the doorway as if he'd been reading the same pulse. He examined the kid with clinical calm, then looked at Megumi. "Not normal cursed energy."

A laugh crawled out of the infected's throat, wet and wrong. He lunged, faster than his shaking body should have allowed. One of the players, a mid-rank sorcerer named Kaito, took the bite and staggered back, blood flashing under the light. He barked, more in shock than pain. "I-he bit me!"

Panic is a contagion easier than any virus. The room's temperature shifted; someone yanked a curtain, revealing the street where three more figures lurched from an alley, moving with jerky coordination. The hunted became the hunter. Phones blinked emergency messages about the game's rules, about territory-irrelevant now. Among yen for points and survival, a new, baser fear rose: infection.

Megumi's heart sank. He'd come to this ward to scout for allies-Yuta, Kugisaki-anyone to make sense of the Culling Game's shifting hazards. Now he had to do triage. "Contain them," he ordered. His voice was steady because it had to be. "Kill only if necessary. We don't know what's going on."

"Kill 'em," someone shouted from the back, eyes wide with a kind of animal logic. "You can't let it spread."

"Not if we can avoid it," Nanami countered. "You saw how he moved. Ordinary killing techniques risk contamination. We need distance and control."

Distance, control-how do you carve that in a room shrunk by panic? A woman with a cursed tool-a rusted cleaver passed down in her family-dove forward, feinting to draw the first infected away. Megumi threw his shadow beasts, a pair of wolf-like shikigami that crashed into the staggered bodies, snapping jaws of conjured force. The infected fell, rose, attacked again. The wolf's teeth found no purchase on flesh that seemed to reject ordinary pain.

"That's impossible," the woman hissed as blood splashed her sleeve. Her hand trembled as she held out the cleaver; the blade vibrated faintly, repulsed by an energy pattern she didn't recognize. She glanced at Megumi with something like blame. "This isn't just cursed energy."

"If it's not cursed, it might be a biological factor," Nanami said. "We treat it differently."

Biology didn't fit neatly into the Culling Game's rules. The game legitimized killing, framed the city's chaos as a board of prizes and punishments. A pathogen cared nothing for those rules. It moved silently through bites, scratches, contact with bodily fluids; in cramped shelters, in alliances, in the exchange of food and trust. As they spoke, another participant-the jovial, rotund Kanji-began coughing up a froth that turned his smile into a rictus. His hand fumbled at his chest before clamping down uselessly. Fear turned to disbelief to a new kind of wrath.

Someone else noticed a pattern. "They all hit the same spots," an exorcist muttered, eyes trained on the semi-animated corpses. "Neck, shoulder, throat. The bites are precise."

"Maybe it's someone weaponizing cursed energy with biological carriers," the hunting rifle man suggested, reloading with hands that shook. "Like a cursed technique combining pathogens."

"Then it's still within our purview," Nanami said sharply. "We adapt. We don't panic."

Adaptation required choices. Megumi felt the tired weight of them. He wanted to march to every neighborhood, warn everyone, lock the city down. He wanted Yuta's face in his mind-Yuta's power and the way he'd always been the kind of person to throw himself into a fire for others. But the timeline of the Culling Game squeezed options thin....
