The Iron Market was a place of hard angles and heavy objects, and right now, every one of them was a potential coffin. Atsu Yuta stood in the center of the plaza, his blood dagger still humming with the kinetic energy of the last parry. The "ON" state was active, but he could feel the drain on his Mana Reserve. Converting the thief's blood into refined energy was a temporary fix; it was a fire that burned bright but fast.
The leader of the mercenaries, a man whose muscles looked like coiled steel under his brass plates, didn't charge again immediately. He was breathing heavily through his gas mask, his eyes fixed on Atsu's hands.
"You're fast, kid," the leader growled, circling to the left. "But I've fought 'shifters' before. You can't hold that shape forever. Every time that red dust clears, you're just a boy in a messy haircut."
Atsu didn't reply. His apathetic gaze was focused on the mercenary's feet. He was calculating the distance, the weight of the cleaver, and the remaining energy in his chest. The mercenary was smart he had noticed the "gap." He was waiting for the OFF command.
Logic State: ON (Blood Dagger). OFF (Displacement Mist).
"Atsu!" Elara called out from the shadows. "He's timing your pulse! Don't reset until he commits!"
The mercenary leader roared and lunged, but it wasn't a reckless swing. It was a feint. He swung the heavy cleaver low, forcing Atsu to parry downward. The moment the blades clashed, the mercenary didn't pull back. Instead, he slammed his shoulder into Atsu's chest, using his superior mass to pin the boy against a rusted shipping container.
Atsu felt the air leave his lungs. The metal container groaned behind him.
"Now!" the leader shouted. "Clear the field!"
The two mercenaries Atsu had previously downed with the blood-wall were back on their feet. One of them raised a heavy, mechanical crossbow, the bolt tipped with a glowing blue suppression crystal.
Atsu saw the finger pull the trigger.
Calculation: Dagger cannot block a suppression bolt. Must switch. OFF.
"OFF," Atsu whispered.
The blood dagger in his hand shattered into a fine, useless mist. The system reset. For a fraction of a second, the loop was empty. This was the "Reset Delay" the window of vulnerability where the anomaly was stripped back down to human flesh.
The suppression bolt whistled through the air, aimed straight for Atsu's heart.
Recreation Loop: ON = Spray Blood (Wall). OFF = [EMPTY].
Atsu's mind raced to rebuild the pair, but the physical shock of the mercenary leader's weight was slowing his cognitive flow. The bolt was inches away.
He didn't wait for the mental "click." He used his physical intelligence. He twisted his body, allowing the mercenary leader's own brass-armored shoulder to act as a shield. The bolt struck the leader's pauldron, the blue crystal shattering and releasing a wave of numbing energy.
The leader screamed as his arm went limp, the suppression magic backfiring into his own nervous system.
"My arm! You little rat!"
Atsu shoved the paralyzed man away. The window had closed. The system was back online.
Activation: ON.
Atsu thrust his left hand toward the crossbowman. Instead of a solid wall, he envisioned a wide, horizontal fan. A violent spray of blood erupted, expanding into a mist-shield that didn't just block the next bolt but obscured the entire plaza in a thick, iron-scented fog.
Inside the red haze, Atsu's "数字" tattoo glowed with a predatory light. This was his terrain now. He could sense the blood of his enemies moving through the fog the rapid thumping of their hearts, the heat of their anger.
"Where is he?" one of the mercs yelled, swinging his cleaver wildly through the mist. "I can't see the kid!"
Atsu moved like a ghost through his own biology. He appeared behind the crossbowman, his hand already positioned near the man's neck. He didn't use a weapon. He used the Hand Conduit.
He didn't drain him to death. He just took enough.
A sharp tug of energy pulled from the man's jugular, a thin ribbon of red entering Atsu's palm. The mercenary collapsed into unconsciousness, his mana-levels bottoming out as his blood-flow was momentarily disrupted.
Reserve Refilled: 40%.
Atsu stepped out of the fog, facing the leader, who was still clutching his paralyzed arm. The mist began to settle, coating the Iron Market in a fine, rusted dust.
"The Guild said you were a danger to the city," the leader wheezed, looking at his fallen men. "They were wrong. You're a danger to everything that breathes."
Atsu stood over him, his expression as detached as ever. He reached behind his ear, took the unlit cigarette, and finally put it back. He didn't feel like a victor. He felt like a machine that had just barely avoided a malfunction.
"Tell the people who hired you," Atsu said, his voice cold. "The next time I have to reset, I won't be using a wall. I'll be using your blood to build the next one."
The mercenary leader scrambled away into the darkness, leaving his gear behind.
Elara stepped out from the shadows, her amber staff glowing softly. She looked at the red dust on the ground, then at Atsu. "That was close, Yuta. Your 'Reset' is a death trap if you're outnumbered by someone who knows the rhythm."
"I noticed," Atsu said, his breath finally evening out. "The system is slow."
"It's not slow," Elara corrected, walking toward him. "It's incomplete. You're treating it like a tool you use. You haven't realized that the ON and the OFF are part of the same breath."
She stopped in front of him, her eyes searching his face. "The Guild is moving up the schedule. Those weren't just mercenaries. They were 'Hounds' trackers used to test the limits of Type 3 targets. They have the data now. They know your window is half a second."
Atsu looked at the cross tattoo on his hand. Half a second. In a world of instant-casting mages, half a second was an eternity.
"Then I need a better pair," Atsu said.
"You need a better teacher," Elara replied. "But first, we need to get off the streets. The 'numbers' are shifting again."
Atsu looked at his reflection in a puddle of rainwater. The "数字" tattoo had changed. The lines were sharper, the count lower. He didn't know what happened at zero, but for the first time, he was afraid to find out.
