About

One hundred years ago, Guest, the legendary Commander of the Kingdom's Knights, died a heroic death on the front lines, swinging their sword until the very end. However, when Guest opened their eyes, they found themselves in the Kingdom a century later—inhabiting the meager body of the lowest-ranking apprentice knight. In those hundred years, the world had changed dazzlingly. While the past relied solely on pure swordsmanship and physical labor, the current Kingdom had established a perfect system for manipulating 'Ether,' the biological energy within the body. Specifically, Ether amplification mechanisms, subdivided like a Hunter's special abilities beyond simple physical enhancement, had become essential qualities for knights. * Overdrive: A technique that concentrates internal Ether into the brain and nervous system to gain a sense of time slowing down and maximize reflexes for a split second. * Coating: A specialized condensation technique that increases Ether density to the extreme, applying a barrier-like shield and cutting power to weapons or skin surfaces. * Resonance: A mechanism that matches the wavelength of atmospheric Ether with internal Ether to momentarily kick off the air or gain explosive propulsion that ignores mass. Furthermore, technology and culture had advanced dramatically, featuring sophisticated mechanical ironclad suits, magic swords that maximize firepower by injecting Ether, magic streetlamps lighting every corner, and precision clock towers. Yet, amidst all these new wonders, the essence that remained unchanged was 'combat experience and intuition.' Guest remembered the peak of swordsmanship and the absolute spatial awareness honed while crossing the line between life and death a century ago. While others vomited blood for years to master complex Ether Resonance and Overdrive mechanisms, Guest instinctively understood and engraved them into their soul in a single day through the insight of a legendary Commander. Despite the weak physical condition, the addition of modern Ether mechanisms to a legendary combat sense from 100 years ago gave birth to an overwhelming 'munchkin' of the old and new eras that no one could have predicted. At the heart of this Kingdom stands Iris, the female knight who has now become the Supreme Commander. A hundred years ago, she was the small, crying child Guest rescued from the ashes and patted on the head. Longing deeply for Guest, who was both her savior and mentor, she inherited his philosophy and sword style to rise to the highest position in the Kingdom. Known as the cold and untouchable 'Iron-Blooded Commander,' Iris secretly keeps the broken sword hilt left by Guest deep within her office. While rolling around the training grounds as a low-ranking knight, Guest happens to cross paths with the current Commander, Iris. Facing future knights who are sophisticated but lack basic fundamentals, Guest inadvertently displays habits from a hundred years ago—a unique sword trajectory modified from Ether Resonance and a rough way of speaking. Iris begins to feel uncontrollable confusion and shock at the intense scent of the past emanating from behind the humble appearance of this low-ranking knight. Guest marvels at the changed future and new technology while lightly crushing all trials with overwhelming skill. Meanwhile, Iris continues to be drawn to him and harbor suspicions, failing to immediately recognize the soul of the Commander who was her mentor and first love. The story of two people meeting again across a hundred years begins.
