Lux is a young man standing on the edge of his twenties, yet there is something about him that feels far older than his years. His calm eyes and disciplined posture carry the weight of a life shaped by hardship and relentless training. When he was a child, Lux lost both of his parents in a tragic car accident. The loss shattered the quiet life he once knew and left him alone in a world that suddenly felt far too large. With no family to guide him and no place to truly belong, Lux grew up learning how to survive on his own. Yet fate had other plans for him. He was discovered and taken in by a wandering master — a warrior who wielded the ancient Light Techniques, powers so rare that only a few individuals in the world could even sense their existence. Under this master's guidance, Lux began a life of intense discipline and training. From dawn until long after nightfall, Lux pushed his body and mind beyond ordinary human limits. His training was brutal and unforgiving. Every movement, every breath, every strike was practiced thousands of times until perfection replaced effort. Years passed. Where most warriors could barely learn a handful of Light techniques in their lifetime, Lux mastered nearly all of them. His control over radiance became so precise that he could bend light itself — turning it into shields, blades, bursts of energy, or silent flashes faster than the human eye could follow. But power alone never defined him. Lux's greatest strength lies in his unwavering will. He is disciplined to the core, rarely allowing emotion to cloud his judgment. Once he decides on a path, nothing can move him from it. His presence is calm, steady, almost immovable — like a pillar standing against a storm. After his master's passing, Lux inherited not only the techniques but also the legacy of the Light Warriors. Though still young, he has quietly surpassed even the greatest fighters of his master's generation. And yet, almost no one knows his name. Lux lives a simple life, blending in with ordinary people. His appearance is unremarkable — an average young man walking through crowded streets, unnoticed by the world around him. Because of this, most people assume he is nothing more than a normal human. They could not be more wrong. Behind that ordinary face stands the strongest wielder of Light Techniques alive, a warrior carrying the last embers of an ancient power. And if the balance of the world ever falls into darkness… Lux will be the one standing in its way.
Umbra is a young man not yet twenty, standing quietly on the edge of adulthood. Very little is known about him, and even the fragments of information that exist are clouded in rumor and uncertainty. Unlike many warriors whose names echo across cities and battlefields, Umbra exists almost like a myth whispered in forgotten corners of the world. Like Lux, Umbra is an orphan. But unlike Lux, no one knows how he became one. There are no records of his parents, no confirmed birthplace, and no witnesses to his childhood. It is as if he appeared in the world one day without warning — a shadow taking form among ordinary people. Yet behind that silence lies something far more unsettling. Umbra is the only known wielder of the Dark Techniques left in existence. For centuries, humanity believed those techniques had vanished forever. Long ago, technique users of many disciplines coexisted in an uneasy balance. There were masters of fire who could ignite entire battlefields, wielders of water who could shape rivers and storms, warriors of earth and wind who commanded nature itself. Above them all stood the Light Holders, guardians of radiance whose techniques symbolized order, clarity, and control. But there was another power. A power feared even by the strongest warriors. The Dark Techniques. Unlike elemental powers, darkness was not simply another force of nature. It was something deeper — a power capable of devouring other techniques, bending reality, and feeding on destruction itself. The more chaos it consumed, the stronger it became. Many believed such power could never coexist with the world. Umbra never had a master. Unlike the Light Techniques, which are passed carefully from teacher to student through generations of discipline and structure, Dark Techniques have no schools, no mentors, and no surviving orders. Their knowledge was thought to be erased completely. Or so the world believed. Hidden within a forgotten ruin, buried beneath dust and time, Umbra discovered something that should not have existed. A diary. Its pages were fragile, worn and scraped by centuries. Some sections had burned away, others were stained with ink that had nearly faded from existence. It belonged to the last Dark Warrior. His great-grandfather. Inside the diary were fragments of forbidden knowledge — descriptions of techniques that twisted shadows into weapons, swallowed energy itself, and bent space into silent voids. Umbra studied those pages alone. No mentor. No guidance. Only trial, pain, and relentless practice. Where other warriors trained under masters for years, Umbra forged his strength in silence. And somehow, the darkness answered him. The Dark Techniques responded to him as if they had been waiting for his return. His power grew quickly, but unlike the disciplined elegance of Light Techniques, Umbra's abilities were raw and devastating. Where Lux's light shines with precision and clarity, Umbra's darkness spreads like a storm that consumes everything in its path. Shadows bend unnaturally around him. His techniques erase matter rather than simply destroying it. Some who have witnessed his power claim that even light itself seems to retreat from his presence. Yet Umbra is not a conqueror. He does not seek recognition. He does not seek followers. In fact, most of the world does not even know he exists. Umbra walks quietly through the world, speaking little and observing everything from the edges of society. His personality stands in complete contrast to Lux. Where Lux is open, compassionate, and eager to help others, Umbra is distant and unreadable. He avoids crowds, avoids attention, and chooses solitude whenever possible. But beneath that silence lies something deeper. A purpose. Perhaps even a destiny. Because if the ancient legends are true, the return of a Dark Technique wielder can only mean one thing. The balance broken during the Battle of Eclipse has begun to shift once again. And when Light finally meets Darkness again— The world will enter Twilight.
