The Paradox of the Flesh

The human eye blinks at an average speed of three hundred milliseconds. For Shinichi Rei, those three hundred milliseconds were an intolerable waste of information.

Seated in the car of the Tokyo metro's Oedo Line, Shinichi held his old notebook. His eyes scanned the passengers. Subject A: slight tremor in the left index finger, nicotine addiction, high stress levels. Subject B: dilated pupils while looking at the phone, cheap dopamine. He didn't watch people out of empathy; he studied patterns of human behavior. Criminology was a game of chess where the criminal always left a piece misplaced.

Suddenly, the car's liquid crystal screens flickered.

The interactive cosmetics advertisement distorted into a violent, greenish static. The train groaned—a metallic screech that resonated in everyone's stomach—and the emergency brakes slammed on. Passengers were thrown from their seats.

Shinichi rolled across the floor, bracing for the impact with his shoulder. The train had come to a dead stop in a dead section of the underground tunnel, a half-built station covered in scaffolding and plastic sheeting.

The lights in the car went out. In their place, the flickering screens displayed a single message in burning red code:

[THE NEXUS: CONTRACT DUEL DETECTED]

[FILTERING REALITY... 99%]

[BETS OPEN]

"What the hell...?" muttered a passenger, holding up his phone. There was no signal. Only an unknown application that had installed itself, showing a live stream of the very same dark station where they were stranded.

Shinichi stood up. The atmosphere wasn't just dark; the air felt thick, heavy, as if the oxygen had turned into mercury. An invisible vibration made the train windows tremble.

The automatic doors of the car were torn open from the outside. Not by an explosion. By human hands.

The Board of Blood and Neon

Outside, under the flashing lights of the construction site, two men faced each other.

One was a two-meter-tall titan dressed in a frayed tactical vest. The other was a slender guy in a long coat with a glowing earpiece implanted directly into his ear cartilage.

"Your intellect won't save you today, lab rat!" roared the giant.

Shinichi, peer-watching from the gap in the train car, saw something that defied every law of physics he had ever studied at university. The giant's body began to glow with a translucent, dense, and violent aura. The air around him distorted from the heat.

The Pulse.

The giant lunged forward. His speed was inhuman. The concrete floor cracked beneath his boots, leaving tracks of destruction with every step. He threw a straight punch directly at the man in the coat. The impact generated a sonic shockwave that shattered the remaining windows of the train.

Estimated destructive force: equivalent to a hydraulic ram at maximum power, Shinichi's brain calculated automatically, frozen by adrenaline. If that hits a bone, it pulverizes it.

But the man in the coat didn't flinch. He simply smiled as he touched his earpiece.

"Prediction calculated," said the strategist, his voice amplified by a throat microphone. "Your Pulse increases your muscle mass by 400%, but it reduces your peripheral vision due to blood pressure in your eyeballs. You drift three degrees to the left when you strike in anger."

The strategist took a millimeter-precise step to the right. The giant's fist passed a millimeter from his cheek. At that exact moment, the strategist pressed a button on his smartphone.

A civil inspection drone, hacked and hidden in the ceiling rafters, dove down and fired a low-frequency industrial laser straight into the giant's eyes.

"Damn you...!" the giant screamed, temporarily blinded, smashing a steel scaffold with a blind blow of frustration.

Logic Against Force

The combat was a choreography of brutality and software. The giant used his Pulse to demolish the environment, throwing half-ton concrete blocks as if they were pebbles. The strategist moved like a ghost, utilizing hacked emergency lights, small explosive charges pre-installed on the pillars, and statistical data to dodge the inevitable.

However, the power gap was insurmountable. The strategist was bleeding from the nose; the sheer air pressure from the giant's punches was destroying his internal organs.

"Your time is up, know-it-all," spat the giant, wiping the blood from his eyes. The aura of his Pulse doubled, turning a crimson red. "I'm going to collapse this tunnel with you inside."

The giant concentrated all his energy into his right leg. The ground began to liquefy under the pressure.

"If you hit that pillar..." the strategist coughed blood, his wrist-mounted laptop smoking, "the ceiling will give way. We will all die. Even the civilians in the train."

"The Nexus loves collateral damage. It drives up the stakes."

The giant raised his foot. The final blow was about to bury them all.

The Awakening of Zero

Shinichi Rei analyzed the situation in microseconds.

The load-bearing pillar is four meters from the giant. The trajectory of his stomp will generate a shockwave at a 45-degree angle. The train car will collapse 1.2 seconds after impact. There is no physical escape. My maximum running speed is 7 meters per second. Probability of survival: 0.003%.

Fear should have paralyzed him. But Shinichi's brain worked differently. In the face of absolute chaos, his mind demanded order. It demanded an equation.

How do you stop an infinite vector of force? You can't counter it. You have to redirect it. You have to understand it.

Shinichi leapt from the car, landing directly in the danger zone, right between the giant and the strategist.

"Get out of there, you idiot kid!" yelled the strategist.

The giant brought his foot down with the force of a meteor.

In that instant of imminent death, time seemed to stop for Shinichi. His obsession with analyzing details, his cold detachment from fear, and his relentless need to decipher others' behavior shattered a lock in his own mind. The energy lines of the giant's Pulse became visible to him. They weren't magic; they were vectors, frequencies, perfect bioelectric vibrations.

His mind, a completely blank canvas free of any predetermined fighting style, mimicked the exact frequency of the attack before it touched the ground.

Archetype: Tabula Rasa.

Shinichi didn't block the blow. He didn't have the strength to do it. Instead, he extended his left palm and touched the giant's knee at the exact millisecond the foot descended. Using the perfect copy of the energy flow his brain had just processed, he altered the angle of the giant's force by a mere two centimeters.

The giant's foot slammed into the ground.

BOOM.

The concrete erupted, but the shockwave didn't head toward the load-bearing pillar or the train. It shot out in the opposite direction, shattering a solid rock wall at the back of the tunnel.

The silence that followed was sepulchral, broken only by the dripping of water from ruptured pipes.

The giant blinked, staring at Shinichi, who remained standing, hand extended, breathing heavily. His eyes, once ordinary, now reflected an absolute void—a clean slate that had just erased the most powerful attack in Tokyo's underground.

"You..." muttered the giant, taking a step back. "Your energy flow... it changed to match mine exactly. Who are you?"

Shinichi looked at his own hands. They were trembling, but not from fear. A cold, analytical smile—one he had never worn before—spread across his face. The chess game had just shifted in scale.

"My name is Shinichi Rei," he said, as the Nexus screens throughout the tunnel began to recalculate the wagers, going wild over his name. "And I think I just figured out how your board works."
