Muren turned around and left.


    The corridor’s frozen silence clung to him like a second skin.


    Inside his chest, a cold sense of satisfaction took hold. There was no joy in victory—only a calm, as if the dust had finally settled.


    The contract was fulfilled. The conditions were met.


    He carried out the war spirit’s command with violent efficiency.


    He had never wanted to be a hero; he only fixed a tactical loophole.


    Bullying destabilized the fragile balance of the ecosystem, and now, fully armed, he had simply rebalanced the scales.


    Whispers followed his footsteps, vibrating in the usual campus noise. But their tone was completely different - wrapped in awe and tempered with neurotic fear.


    He felt eyes on his back—not the contemptuous indifferent scorn, but sharpened attention..


    He was no longer invisible. He had cast a shadow.


    Turning the corner and leaving chaos behind, another presence quietly arrived.


    It wasn’t oppressive; it was a kind of... resonance.


    The air around him shifted subtly, and he felt an intuition of being watched—


    not by ordinary eyes, but by something... inhuman.


    He felt it before he saw it. A prickling sensation on his skin, the air growing subtly colder, the faint metallic tang of the Dragon’s Blood incense he’d burned earlier, inexplicably returning, ghosting the air around him.


    Then, a visual flicker at the periphery of his vision, a distortion of light, a momentary shimmer in the mundane hallway air.


    He stopped walking, turning slightly, his senses sharpening, instinctively knowing what – who – was approaching. Not physically, not in the mundane sense, but… spiritually. The War Spirit.


    The shimmering intensified, coalescing, resolving itself into a form, visible only to Muren’s heightened perception, a layer overlaid onto the ordinary school hallway, unseen by the oblivious students bustling past.


    It wasn''t a creature of flesh and blood, but of… essence. Shaped like a warrior, yes, vaguely humanoid, but sculpted from something akin to smoke and shadow, constantly shifting, edges blurring, yet undeniably there.


    Armor of obsidian seemed to flow and reform around a core of flickering crimson light, suggesting a form both ancient and eternally in flux. No face was clearly defined, just a helmeted silhouette, and from within the shadows of the visor, two points of burning red light fixed on Muren, intense and unwavering.


    The sound did not come from the corridor, but roared directly in the depths of his consciousness - deeper and richer than any ordinary sound, carrying the weight of thousands of years of blood and fire, the clang of steel clashing, and the howl of dead battlefields..


    “Satisfactory.”


    The echo of recognition wrapped in the single word contained no emotion, but it radiated an almost substantial... pressure.


    The War Spirit’s assessment. Concise. Unambiguous. Commendation from a being of pure martial divinity.


    Muren remained impassive externally, but deep in his consciousness, sparks flared— something akin to… pride? Acknowledgement? registered deep within. He had met the spirit’s demand, proven his worth in the colosseum of Sakuragoka High School, a concrete jungle.


    “You wield the Locked Jab with… potential.” The spirit continued, the mental voice echoing with a low hum of power. “But a single strike is not war. A single jab, not a complete arsenal.”


    A lesson. Always a price, always a demand for more, for greater strength, for deeper mastery. The War Spirit was not offering praise, but laying the groundwork for further expectations.


    Then, the spirit shifted, the smoky form subtly changing, the crimson light within intensifying, pulsing with energy. “I bestow upon you… Flowing Roundhouse.”


    Images flooded Muren’s mind, not words this time, but sensory data, kinetic information. He saw the movement, not visually, but felt it in his muscles, in his bones, in his very sense of balance. A whirling motion, a circular kick, powerful, fluid, adaptable. He felt the subtle shifts in weight, the precise pivoting of the foot, the controlled extension of the leg, the focused snap of impact.


    He understood, instinctively, immediately. The Clairvoyant Eye, the Windless Paradise – they weren''t just separate abilities, but synergistic components, working in concert to enhance this new technique, to elevate it beyond a simple roundhouse kick into something…adaptive. Flowing Wind Roundhouse.


    “Clairvoyant Eye guides the trajectory. Windless Paradise smooths the flow. Adjust, adapt, redirect in motion. Exploit every opening. Maximize every strike.” The spirit’s instruction was concise, brutal, efficient. Martial doctrine distilled to its purest form.


    A case of content theft: this narrative is not rightfully on Amazon; if you spot it, report the violation.


    The crimson light pulsed again, and the feeling of the technique solidified within him, muscle memory imprinted directly onto his being, a warrior’s knowledge bestowed in a moment. He felt the power thrumming in his leg, the potential for a devastating, adaptable strike now added to his arsenal.


    “Next service… will be given when the wind dictates.” The War Spirit’s voice echoed in his mind, a statement of fact, a promise of future trials, of ongoing obligation. “Be ready.”


    Then, as abruptly as it had appeared, the spirit’s presence began to fade. The shimmering lessened, the metallic scent dissipated, the cold air warmed back to normal hallway temperature. The warrior form dissolved back into the mundane reality of Sakuragoka, leaving behind only a lingering sense of… expectation. And a newfound power humming within Muren’s very being.


    He stood there for a moment longer, internalizing the spirit’s benediction, the weight of the pact settling deeper, becoming a part of him. Adaptive Roundhouse. Flowing Wind Roundhouse. The words resonated within him, not just as a technique, but as a philosophy. Adapt. Flow. Be like the wind, elusive, unpredictable, powerful in its adaptability.


    Muren walked forward, each step accompanied by the rhythmic tapping of his heels against the floor—almost as if he was taking measurements for a secret ritual. He slipped through the flickering sunlight in the hallway and into his next class.


    <hr>


    The moment Muren stepped into the classroom, the pre-class chatter seemed to be cut off by a sharp blade.


    Heads turned all at once. Eyes clung to his figure like iron filings sticking to a magnet, only to quickly scatter.


    Some pretended to fiddle with their stationery. Others suddenly stared out the window.


    However, the tight lines of their shoulder blades betrayed the trembling silence. Unspoken questions floated in the thin air, so thin that the hissing of static electricity could be heard.


    He moved to his desk, deliberately ignoring the subtle shifts, the averted gazes, the pregnant silence. He unpacked his books, meticulously arranged his stationery, creating a small island of normalcy in the suddenly altered landscape.


    Muren still looked harmless on the surface, but his dormant ghost diluted his outline in the morning light. The aftershocks of the fight in the hallway were buzzing deep in his organs, and the residual pressure of the war spirit was like high-voltage electricity running through the skin, and every tendon was soaked in the buzzing sound that had not yet cooled down.


    At the other end of the classroom, Muren didn’t even need to look directly to sense the ripple of Biāo''s gang. Those guys were huddled in the back, and their once-arrogant swagger had shrunk into a small bundle of trembling whispers.


    In those venom-laced whispers, someone used a sidelong glance to cut through his silhouette. But the moment the Muren turned his head, that glimpse vanished in a hurry. His gaze burned a mark on the retina like a flickering tungsten filament.


    Most agitated of all was the skinny lackey. His knuckles tapped nervously on the desk, and every few seconds he turned to steal a glance down the corridor. His Adam’s apple bobbed with each swallow, as if, at any second, Biāo might kick the door in—carrying a dignity crushed by Muren''s fierce fighting spirit—to collect a debt in blood.


    Biao himself was absent. Wisely, perhaps. Or strategically. Muren calculated the possibilities. Biao wasn''t one for rash decisions. Humiliated, yes, enraged certainly, but not stupid. He would be regrouping, reassessing, planning his next move. Brute force had failed. He’d adapt, find a different angle, exploit a different weakness. If any existed.


    The classroom door slid open again, and Chun lumbered in, his entrance lacking its usual swagger, his movements stiff, almost hesitant. He walked with a noticeable limp, favoring his left side, his face pale, a faint sheen of sweat on his brow despite the cool morning air. His eyes, still slightly unfocused, scanned the room, lingering on Muren for a fraction of a second before quickly averting, shame and residual confusion warring with simmering resentment. He moved to his usual seat, slumping down heavily, avoiding eye contact with everyone, radiating a wounded, bewildered aggression.


    Brad was conspicuously absent. Muren surmised he was likely in the infirmary, or perhaps even sent home, nursing not just physical pain, but a deeply bruised ego. Public humiliation was a sharper weapon than any fist in Sakuragoka’s social hierarchy.


    As the teacher entered, the superficial normalcy of classroom routine reasserted itself, the pretense of learning masking the undercurrent of tension still thrumming beneath the surface.


    Lessons began, textbooks opened, the drone of instruction filled the air, but the undercurrent of whispers, the subtle shifts in gazes, the unspoken questions, remained. Sakuragoka was holding its breath, waiting for the inevitable aftershocks.


    Between classes, a crumpled paper ball quietly landed on Muren''s desk. He lowered his gaze, noticing ink seeping through the creases. Rubbing it open with his fingers, he saw the scrawled handwriting crawling across the wrinkles:


    “Heard what you did. Thanks. Be careful.”


    No signature.


    Was it Kenji? Or perhaps another once-cowed prey, revived by Muren’s defiance, offering silent gratitude and warning through trembling strokes.


    Muren crushed the paper into his palm and stuffed it into his school uniform pocket. A ripple that materialized, physical evidence of the trembling food chain in the battle jungle. He was no longer a ghost. He was a blade that was catalyzing its own fission.


    After classes, as students streamed out into the lunch break chaos, Muren deliberately avoided the hallway where the earlier confrontation had occurred. He sought out the quiet solitude of the rooftop, needing space to process, to recalibrate, to train.


    The north wind was blowing across the rooftop, and the desolate silence formed a hideous gap against the noisy and boiling campus below.


    The steel guardrails trembled and emitted a metallic whine, and the sound of the pigeons flapping their wings was crushed into dust by the air current. This was the vacuum zone scorched by the War Spirit’s gaze, where even sunlight itself cut glass-sharp against hunched shoulders.


    Perfect.


    He needed to test the Flowing Roundhouse, to integrate it into his movements, to solidify the War Spirit’s gift into muscle memory.


    He closed his eyes, recalling the spirit’s instruction, the sensory data imprinted in his mind – the flow, the adaptation, the redirected force. He shifted his weight, visualizing the movement, feeling the phantom spin of the kick in his muscles.


    Then, he began to practice. Slowly at first, deliberately, focusing on form, on balance, on the precise pivoting motion, the controlled extension of his leg. The wind whipped around him, a constant presence, but Windless Paradise hummed softly, creating a pocket of relative calm, allowing him to focus, to move with precision despite the gusts.


    He practiced the basic roundhouse, feeling the mechanics of the kick, then began to incorporate the adaptive element, visualizing an opponent shifting their guard, anticipating their reactions, adjusting the kick’s trajectory mid-motion, high, low, sweeping, snapping, flowing like the wind itself.


    Time blurred into a focused intensity of motion and refinement. He practiced until his muscles burned, until sweat stung his eyes, until the rooftop wind seemed to whisper encouragement, or perhaps, just observation. The Flowing Roundhouse began to take shape, not just as a technique, but as an extension of his own body, a fluid, adaptable weapon.


    As dusk began to paint the sky in hues of orange and violet, a different kind of whisper reached him, not the wind around him, but a voice within his mind, deeper, more resonant, the familiar clang of the War Spirit.


    “Service is needed.”


    The sound of explosion in the depths of consciousness was like a guillotine falling, without any warning. The fleeting sense of control he’d honed during the silent time of rooftop training shattered to dust before the War Spirit’s irrefutable command. A contract was never a gift—it was a chain laced with poison, tightening its very first link.
