Tetsuro's Full Backstory:
THIS PART CONTAIN SPOILERS
Tetsuro was born into a peaceful family of scholars on the outskirts of a kingdom now forgotten by time. His parents were revered for their knowledge, but they lived quietly, far from the power struggles of the realm. From a young age, Tetsuro demonstrated a unique blend of wisdom and calm, far beyond his years. He was a natural philosopher, absorbing knowledge at an unprecedented rate. But despite his intellect, he never sought fame or glory. Instead, he found solace in the written word and the study of human nature.
However, peace was fleeting. His family's collection of ancient texts, regarded as priceless, made them a target for warlords and treasure hunters. One fateful night, marauders attacked their home. Tetsuro's parents fought valiantly, but their pacifist beliefs were no match for the brutality of the invaders. In the chaos, Tetsuro barely escaped with his life, carrying only one artifact—a scroll containing an ancient technique that had been long forgotten by the world: the power of Sealing.
The technique of Sealing was a mystic art, one that allowed the wielder to lock away not only physical entities but the very essence of life, emotions, and power. This scroll held the key to mastering this profound ability, and Tetsuro, guided by his desire for peace, vowed to master it.
As he traveled the lands in search of more knowledge, he encountered countless warriors and beasts. Many of these creatures were born from the chaos and violence that plagued the world. Tetsuro, in his pursuit of peace, began to see the destruction wrought by these beings. They were not just monsters—they were manifestations of the violence and suffering the world had created.
Over time, Tetsuro discovered that consuming the corpses of these beasts gave him access to their essence, their raw power. The act was not born out of hunger, but necessity—by eating the remains, he could absorb their energies and refine them, gaining strength without needing to shed blood or create more suffering. This was the path he chose, seeing it as a way to use the power of destruction to fuel his personal growth and preserve the fragile peace he sought.
With the Sealing technique and the power of the monsters he consumed, Tetsuro became a figure of immense knowledge and power. He could suppress destructive forces, locking away chaos within himself to prevent it from consuming the world. His travels eventually led him to the Kurokaji Clan, where he met Yizorushi, a dragon destined for greatness but torn by his own destructive tendencies.
