Chapter 18: Kira’s Midnight Hunt
The Valerius manor was completely silent, bathed in the pale light of a crescent moon. In his bedroom, Ren sat at his heavy oak desk, a single runic light illuminating his workspace.
He was peering through a makeshift microscope he had constructed using carefully manipulated quartz lenses, examining the dark, pulsating purple crystal he had extracted from the Alpha Silt-Drake.
"The crystalline lattice is organic," Ren murmured to himself, writing a string of equations in his notebook. "It’s acting like a parasitic neural node. It interfaces directly with the host’s spinal cord, hijacking the central nervous system and flooding it with cortisol and adrenaline. It burns out the host's body in exchange for rabid aggression."
A soft rustling sound came from the thick rug by the hearth.
Kira was awake. Since her evolution to the Mythic class Neural-Kinetic Assassin, sleep had been difficult. Her body hummed with an ever-present, low-level static charge. In the dark, her silver fur literally sparked with microscopic arcs of blue electricity as she shifted under her blankets.
She sat up, her fox ears swiveling. Her amber eyes glowed softly in the darkness.
"Master Ren?" she whispered, crawling over to his chair and resting her chin on his knee. "My skin feels... fuzzy. Like bees are buzzing inside my arms."
Ren smiled, setting down his quill and gently stroking her ears. The static electricity safely grounded itself into his skin.
"That is your new electromagnetic nervous system, Kira," Ren explained softly. "In a normal biological body, when you want to move your arm, your brain sends a signal. That signal travels as a chemical messenger across gaps between your nerves, called synapses. It takes time. A few hundred milliseconds. It’s why people flinch after they hear a loud noise."
Kira tilted her head, trying to follow the logic.
"But you don't use chemicals anymore," Ren continued, his thumb gently rubbing the space between her ears, causing a deep, rumbling purr to build in her chest. "Your mana has formed a superconducting magnetic rail down your spine. Electricity encounters zero resistance. The delay between your thought and your action has been reduced to absolute zero."
"I think it, and I do it," Kira summarized, her tail swishing across the floor.
"Exactly. But having a sports car's engine inside a wooden carriage is dangerous," Ren said, turning in his chair to look at her seriously. "If you accelerate instantly, the G-forces will snap your bones and turn your brain to mush against the inside of your skull. You have to learn how to bleed the kinetic energy smoothly. You need to calibrate your vectors."
Ren turned his gaze toward the window, looking out over the moonlit fields toward the village. He had been monitoring the seismic vibrations of the land all night.
"Three infected Dire Hounds broke off from the Silt-Drake pack before we killed the Alpha," Ren stated, his voice dropping into its cold, commanding tone. "They are currently prowling the outer wheat fields, heading toward the village livestock pens. The Baron's guards are asleep."
Kira’s ears snapped straight up. The fuzzy, restless energy in her limbs suddenly found a focal point. The purring stopped, replaced by the coiled tension of an apex predator.
"I will kill them, Master Ren," she stated, her amber eyes flashing with absolute devotion.
"Consider this a live calibration test," Ren nodded. He reached into his desk drawer and pulled out two sleek, high-carbon steel daggers, their edges honed to microscopic sharpness, and handed them to her. "Do not wake Elara or Lyla. Use your aerodynamics to silence your approach. And Kira? Bring me their crystals."
"Yes, Master."
Kira stood up. She didn't walk to the door; she merely intended to be at the window, and a fraction of a second later, she was standing on the sill, the night wind catching her silver hair. With a silent leap, she vanished into the darkness.
The autumn air was frigid, but beneath her standard maid uniform, Ren's pearlescent spider-silk suit regulated Kira's temperature perfectly.
As she sprinted across the open fields, Kira focused on her internal circuitry. She didn't just run; she manipulated the air. She formed the razor-thin wedge of atmospheric pressure in front of her nose, slicing the air resistance. Because her silk suit was entirely frictionless, she generated zero sound.
She was a ghost, crossing two miles of farmland in less than twenty seconds.
She slowed down as she approached the wooden fences of the village livestock pens, remembering Ren's lesson on inertia. She leaned backward, forcing her cleats to carve long, deep grooves into the dirt to bleed off her velocity smoothly rather than stopping on a dime and shattering her knees.
Pant. Pant. Pant.
The tale has been stolen; if detected on Amazon, report the violation.
She heard them before she saw them. The heavy, wet breathing of rabid beasts.
Kira leaped silently onto the branch of a large oak tree overlooking the pens. Below her, three Dire Hounds were pacing. They were massive, muscular wolves, but their fur was falling out in clumps, revealing dark, pulsating purple veins beneath their skin. Thick, acidic foam dripped from their jaws, burning the grass where it landed.
Three targets, Kira analyzed, her mind operating at speeds that made the world around her seem as though it were moving through thick syrup.
A normal assassin would drop down, stab one, and try to fight the other two. But Kira was a Neural-Kinetic Assassin trained by a physicist.
Target one: directly below. Target two: fifteen yards left. Target three: twenty yards right.
Kira closed her eyes and visualized the geometric vectors. She couldn't move in sharp angles at supersonic speeds without tearing her own ligaments. She had to move in a continuous, flowing arc—a parabola of violence.
She tightened her grip on her daggers. She flooded her superconducting spine with mana.
Execute.
Kira dropped from the branch. Gravity pulled her down, but she didn't wait to land. The instant her toes touched the back of the first Dire Hound, her brain issued the command to strike. Because there was zero synaptic delay, her body obeyed perfectly.
Before the hound even registered the weight on its back, Kira’s right dagger severed its cervical vertebrae.
She used the beast's collapsing body as a fulcrum. Her legs coiled like steel springs, and she launched herself toward the second hound on the left.
BOOM.
A sonic crack echoed across the quiet farm as Kira broke the sound barrier over a span of fifteen yards. To the second Dire Hound, the world simply skipped a frame. One moment, its pack-mate was standing. The next, a silver blur passed its peripheral vision, and its head was cleanly separated from its shoulders.
But Kira realized her mistake instantly.
She had used too much force on the jump. Her velocity was too high. The third hound, twenty yards to the right, had turned at the sound of the sonic boom and lunged, its jaws snapping wildly.
Kira was mid-air, hurtling toward it. She couldn't change direction without a solid surface to push off.
Vector change required! her mind screamed.
She thought of Ren’s lessons on centripetal force and rotational momentum. She couldn't stop, but she could spin. Kira violently twisted her torso, throwing her arms out to alter her center of mass. She turned her forward velocity into a rapid, horizontal spin.
She became a silver buzzsaw.
She collided with the leaping hound. Her spinning daggers shredded the beast’s ribcage, completely obliterating its momentum.
However, as they crashed into the dirt together, the hound’s wildly thrashing claw managed to snag the sleeve of Kira’s maid uniform. The razor-sharp talon couldn't pierce the spider-silk armor beneath, but the sheer kinetic force of the impact yanked Kira’s arm violently, pulling the silk back just enough for a secondary claw to graze her exposed wrist.
Kira tumbled across the grass, popping smoothly to her feet and sliding to a halt.
The field fell dead silent. Three infected Tier-2 beasts lay slaughtered. The entire engagement, from the moment she dropped from the tree to her final slide, had taken exactly 1.4 seconds.
Kira stood up, her breath coming in short, excited gasps. The adrenaline was intoxicating. She looked down at her hands. She had moved so fast, calculated so cleanly. She was exactly the weapon Master Ren needed her to be.
Then, she felt a slight sting on her wrist.
She looked down. A thin, shallow cut, barely two inches long, was welling with a few drops of blood. The hound's claw had carried a trace of the acidic, purple mucus.
Kira frowned, pulling a cloth from her pocket and tying it tightly around her wrist. It wasn't a deep wound, but the purple infection stung like a hornet. She quickly moved to the carcasses, expertly extracting the three pulsating purple crystals from their spines, wrapping them in a leather pouch.
She wiped her daggers clean, took a deep breath, and prepared for the run back to the manor.
Master Ren will be pleased with the crystals, Kira thought, her ears drooping slightly in shame. But he is going to be so angry that I let myself get scratched. I miscalculated the jump vector.
Ten minutes later, Kira slipped silently back through the window of Ren’s bedroom.
Ren was still awake, writing in his ledger. He turned as she landed lightly on the rug.
Kira immediately dropped to one knee, offering the leather pouch. "The targets are eliminated, Master Ren. The village is safe."
"Excellent work, Kira," Ren said, taking the pouch. He noted the total lack of blood on her uniform. Her control was improving exponentially. He reached out to pat her head.
Kira leaned into the touch, but as she did, she winced slightly, shifting her weight.
Ren stopped. His high Intelligence stat immediately analyzed her posture. Her left shoulder was tense. Her breathing was fractionally elevated.
"Show me your arm," Ren commanded, his voice losing its warmth, replaced by the clinical, absolute tone of a physician.
Kira guiltily held out her left arm, rolling up her sleeve to reveal the cloth tied around her wrist. The white fabric was stained with a mixture of red blood and a sickly purple hue.
"I'm sorry, Master," Kira whimpered, her tail tucking between her legs. "I used too much force on the second jump. I couldn't alter my trajectory in the air, and one of them grazed me as it died. I failed the physics equation."
Ren didn't yell. He didn't scold her.
He gently untied the cloth. The cut was minor, but the purple acidic infection was slowly eating at the edges of the wound, preventing her natural beast-kin healing from closing it.
"You didn't fail, Kira. You gathered new data," Ren said softly, his dark eyes analyzing the necrotic tissue. "You learned that airborne velocity removes your frictional anchor. Now you know not to jump unless you have a calculated landing point."
"Are you... not angry?" Kira asked, looking up at him with wide, teary eyes.
"I am angry at the beast that scratched you," Ren corrected, guiding her toward his bed and sitting her down on the edge. "But I am never angry at you for learning. Besides, this provides an excellent opportunity for tomorrow's lesson."
Ren placed his hand hovering just an inch over her bleeding wrist.
"Sleep here tonight, Kira," Ren instructed, his mana slowly gathering in his palm. "Tomorrow, when Elara and Lyla wake up, we aren't going to the cavern. We are going to the library. Because it's time I taught my Vanguard the true anatomy of a healing spell, and how to forcibly overwrite cellular corruption."
Kira nodded, her heart swelling with an overwhelming, absolute devotion as Ren's warm mana enveloped her wrist, instantly neutralizing the stinging pain. She was a Mythic assassin, a weapon of unparalleled speed, but to Ren, she was just his precious Kira, and he would always fix her when she broke.
