Synopsis
DEMON SLAYER / FROM CROSSOVER For Jin, a doctor whose caution borders on obsession, survival is a science. In a town plagued by creatures that hunt in the dark, his meticulous doctrine of preparedness is the only thing that has kept him alive. Every action is calculated, every outcome anticipated. But his science cannot account for the impossible. A flicker in reality, a glitch in the nightmare, and Jin is violently torn from everything he knows. He awakens in Taisho-era Japan, a land steeped in tradition and stalked by a new, more sophisticated kind of monster: Demons. Here, warriors of the Demon Slayer Corps battle the darkness with swords and elemental power—a world utterly alien to his own. Armed with advanced medical knowledge that seems like magic to this era, Jin's survivalist mindset is immediately put to the test. His path crosses with Shinobu Kocho, the enigmatic Insect Hashira. In her, he finds a startling reflection of himself—a fellow specialist in poisons and human anatomy, yet her serene smile conceals a purpose and a fury he cannot begin to fathom. At the same time, his new reality is fractured by echoes of the old. Haunting visions of Kristi, a familiar face from the town he left behind, begin to plague him. Are they merely memories, or is the glitch that brought him here something far more sinister and unstable? Caught between the rigid code of the Demon Slayers and the lingering horror of his past, Jin must adapt his doctrine. But in a world where monsters have faces and allies hide deadly secrets, his obsessive caution may no longer be enough to save him. Can a man of science survive in a world of myth? And what happens when the greatest threat is not the monsters you can see, but the glitch in reality that follows wherever you go?

Chapter 0: Protocol for an Unscheduled Variable

The first sound in Jin Nakahara's penthouse apartment was not the gentle chime of an alarm, but the sharp, metallic snap of a katana being sheathed. At precisely 05:00 hours, bathed in the cool, pre-dawn glow of Tokyo, Jin completed his final Kendo kata. His movements had been flawless, each of the one hundred prescribed strikes a testament to a life spent pursuing perfection.

"Morning analysis complete, Master Jin," a calm, synthesized female voice echoed from unseen speakers. "Your father's shipping interests have caused a minor—and I quote the market—'unforeseen ripple' in Nikkei futures. Your mother's presence at the Paris fashion gala has resulted in a 400% increase in social media traffic for the term 'unapproachable elegance'. Both are within expected parameters."

Jin didn't reply, his focus absolute. To him, his family wasn't family; they were sources of chaotic variables he had to account for daily. He was the stoic center of a hurricane of flamboyance and organized crime. His appearance was a gift of their genes—the sharp, handsome features of a model locked in the severe, brooding expression of a man who expects the worst from the universe at all times.

Later, in the kitchen, while preparing a breakfast calculated to the exact microgram of nutrients he required, it happened. A faint tickle in his throat.

A normal person would have cleared their throat. Jin froze. Internal system anomaly detected, his mind raced. Unscheduled irritation of the pharyngeal mucosa. Potential for viral infection: 6.7%. Unacceptable.

"J.A.N.E.," he said to his home's AI. "Cancel my afternoon lecture. I need to acquire medical countermeasures."

"Acknowledged," J.A.N.E. replied. "Shall I have the supplies delivered?"

"Negative," Jin stated, already moving. "Third-party delivery introduces too many points of potential failure."

His garage was a sterile, functional space. In the center sat his chosen vehicle. It wasn't a flashy supercar designed to advertise wealth. It was a statement of intent. A custom, fully-modified Lexus LX 600, its original glossy paint covered in a matte-black, radar-absorbent coating. The subtle, angular lines of custom ballistic paneling disrupted its luxurious silhouette, giving it a menacing, governmental look. It sat on heavy-duty, military-grade run-flat tires that added to its aggressive, practical stance.

He donned his daily attire: a simple black shirt, dark jeans, and his custom-made, lightweight bulletproof jacket. He did a quick systems check on the Lexus, its armored windows humming faintly as they sealed. The Glock 17 was secure in his hip holster. His black, dragon-motif katana was locked in its rapid-release mount by the driver's seat. A final glance confirmed the status of his emergency supplies, neatly organized in custom, hidden compartments. For Jin, this was not an event; it was routine.

At the pharmacy, he methodically cleared the shelves of medicine, bandages, and IV kits, leaving the pharmacist stammering about the apocalypse. Jin's only reply was a cold stare. "I am preparing for a potential fever. The two are not mutually exclusive."

On the drive back, a news alert flashed: UNEXPECTED ROAD CLOSURE ON THE MAIN HIGHWAY DUE TO A FALLEN ANCIENT TREE.

Static Target. Increased Risk. Jin's mind processed. He immediately took the nearest detour, a winding country road that grew older and more desolate with each mile. His high-tech GPS flickered, then died.

He drove over a hill and saw it. A small, quaint town that wasn't on any map. He circled it once, his mind mapping the layout, and tried to leave. The same road brought him back. He tried a second time. Same result. A topographical trap.

He brought the Lexus to a stop in the middle of the street, its powerful engine idling with a low, barely-audible hum. He looked at the setting sun, a grim orange light painting the edges of the strange, imprisoning buildings.

Jin Nakahara, the man who prepared for everything, felt no fear. He felt only the weary exhaustion of being proven right once again.

"Of course," he muttered, killing the engine. "Another unscheduled variable."

His hand rested on the grip of his Glock. "Protocol activated: Secure a defensible position. Establish a perimeter. Begin observation."
