Rain lashed against my face, cold and sharp as needles. From sixty stories up, the neon lights of Neo-Veridia blurred into a smeared sea of electric blue and violent pink. I crouched on the narrow edge of a stone gargoyle, my sneakers gripping the slick, wet surface with practiced ease. Water pooled in the creases of my black tactical jacket, but I barely felt the chill. Training since the age of five had burned away my vulnerability to something as simple as the weather. Every muscle in my body was coiled like a steel spring, waiting for the precise moment to strike. Down below, the city hummed with a chaotic, electric energy. This was a playground for the powerful, a metropolis where SSS-Rank heroes and ruthless mercenary lords waged a silent, devastating war for control. Most fifteen-year-olds were asleep right now, dreaming of high school exams, sports, or video games. My reality was vastly different, defined by a blade dripping with fresh blood and a heart that beat in perfect, silent rhythm. Tonight, my target sat inside the penthouse directly below me, completely unaware of the doom perched above him. His name was Senator Vance, a corrupt politician who had crossed the wrong people. He believed his S-Rank bodyguards and bulletproof glass made him safe from the world's dangers. They couldn't stop the dark. My hand slipped into my pocket, fingers brushing against the cold steel of my custom-forged throwing stars. Each star was engraved with the unique crest of the Kurogane clan—a reminder of who I belonged to, of what I was. Focusing my mind, I let my consciousness slip into the pitch-black space beneath my feet. Darkness stretched, peeling itself off the stone ledge like living liquid, expanding into the rainy night. It felt cold, a familiar numbness that spread from my chest down to my fingertips. This was my EX-Rank Shadow Manipulation, a terrifying anomaly that granted me control over the dark. I could summon clones, store an arsenal within my shadow, and slip through the darkness undetected. Ordinary people saw me as just Kenji, a quiet high schooler who kept his head down and tried to blend into the background. Underneath that boring exterior lay a weapon trained to kill without hesitation. Memories of my childhood often drifted back to the harsh training grounds of my family's estate. Monks and mercenaries had beaten the weakness out of me in windowless concrete rooms, forcing me to hone my gifts through blood and pain. They taught me that relationships were liabilities, that emotion was a disease, and that my only value lay in my obedience. "You are a shadow, Kenji," my father's voice echoed in my head, cold and unyielding as a winter grave. "A shadow does not feel. It does not regret. It only obeys." I had believed him for a long time, accepting my fate as a tool of death, a weapon to be pointed and fired. But then came Lyra. She had moved into the house next door three years ago, bringing a chaotic brightness into my dark world. She was loud, clumsy, and possessed an absurdly positive outlook on life that I found both baffling and secretly comforting. We walked to school together every morning, sharing cheap convenience store snacks and talking about nothing of importance. Pretending to be normal was a beautiful, fragile lie, a temporary sanctuary from the blood on my hands. I would do anything to protect that lie. Living a double life was an exhausting game of chess. Every word I spoke at school had to be carefully measured, every reaction meticulously fabricated. When Lyra talked about her dream of becoming a hero who saved everyone, I had to smile and nod, hiding the cynical sneer that wanted to break through my lips. Heroes did not save everyone; they only saved those who could afford their protection or fit their narrative. Our world was far more ruthless than she realized. Rumors had been circulating about a wealthy SSS-Rank heiress who commanded teleportation and telekinesis, a girl whose family held immense sway over the city's infrastructure. Our paths had not crossed yet, but in our line of work, collision was inevitable. For now, my focus remained on the immediate threat—and the job at hand. Slithering down the sheer concrete face of the skyscraper, the dark tendril of my power crept toward the penthouse balcony. Red beams sliced through the heavy rain, crisscrossing in a complex grid. My shadow flowed beneath them, flat against the wet stone where the light could not reach. Lasers detected physical mass, but they could not detect a lack of light. I guided the darkness through a microscopic gap in the window frame, slipping into the warmth of the senator's study. Vance was pouring a glass of amber liquor, his hands shaking slightly from some unseen anxiety. He had sold out three mutant orphanages to the black market, thinking the transactions were completely erased from the digital world. My family did not care about his morality, only the high-paying contract on his head. I watched him through the eyes of my shadow construct, feeling nothing but a dull, hollow quiet. He was just another task, another name to cross off the list. My EX-Rank power allowed me to do more than just manipulate darkness. I could feel the heartbeat of every living thing within a fifty-meter radius, translated through the vibrations in the shadows. Two guards patrolled the hallway outside Vance's study, their heart rates steady and calm. They had no idea that death had already bypassed their high-tech security systems and entered the inner sanctum. Swiftly, the shadow rose from the floorboards behind his leather chair, shaping itself into a tall, featureless silhouette. It did not make a single sound. Even the dust motes in the warm room remained undisturbed as the dark figure solidified. Temperature in the room plummeted instantly. Vance suddenly froze, perhaps feeling the unnatural drop in temperature as the darkness drew near. He turned around, his glass slipping from his fingers to shatter on the plush rug. Before he could press the panic button under his desk, my shadow-blade lunged forward. One clean stroke severed his throat with surgical precision. Blood sprayed, painting the mahogany desk, but my shadow absorbed the sound of his dying gurgles. He slumped forward, his eyes wide with a terror that would never find an answer. Watching him die brought no joy, no remorse, only the cold satisfaction of a job cleanly done. I was my clan's perfect, unfeeling tool. --- Pulling the shadow back to me, I prepared to slip away into the rainy night. My job was finished, and the trace would be gone before the guards realized their boss was dead. I could go back to my quiet room, sleep for a few hours, and walk to school tomorrow. I could pretend to be normal. Suddenly, a violent crack of thunder shook the entire skyscraper. A brilliant flash of azure lightning tore through the dark clouds, illuminating the sky with blinding intensity. My heartbeat spiked with unfamiliar panic as the energy signature washed over me. It was too powerful, too distinct to be a natural storm. Hovering in the air, framed by the electric storm, was a figure I knew all too well. Lyra. She was in her full SSS-Rank superhero suit, the silver-and-blue armor humming with raw, crackling electricity. Electric static whipped around her face in the gale, glowing with pure energy. Those glowing, electric blue eyes were staring directly at the shadow construct I had left behind in the room below. Breath hitched in my throat as I shrank back into the deepest recess of the roof. We had shared a bench at lunch just eight hours ago, arguing over a silly math homework assignment. She had laughed, her eyes bright and completely devoid of the fierce, lethal focus she held right now. If she looked up, she would see me. Discovery meant death, shattering the fragile illusion of my peaceful life into a million pieces. She floated downward, her boots touching the wet balcony floor with a soft click. Glass shattered inward under her immense SSS-Rank pressure. Stepping into the room, her gaze immediately locked onto the lifeless body of Senator Vance. I watched through the tiny sensory link I had left behind—a microscopic speck of shadow hidden under the edge of the desk. Kneeling by the corpse, her expression tightened with a mixture of anger and grief. "No," she whispered, her voice trembling slightly. "I was too late." Her hand reached down toward the floor, searching for any clue the assassin might have left behind. My breath hitched as my shadow-clone-sensor registered her fingers brushing against a small, metallic object that had slipped from my sleeve during the struggle. As Lyra descends to inspect the corpse, Kenji's shadow-clone-sensor detects her picking up a discarded, custom-forged mercenary throwing star—engraved with the unique crest of his own clan.
