Tetsuo was once a celebrated samurai, a master swordsman feared for his skill and revered for his honor. But after his entire clan was betrayed and slaughtered in a violent coup, Tetsuo was left without purpose, haunted by the screams of his comrades and the weight of his own survival. Now, he is a ronin—a masterless wanderer. His only companion is his sword, Shinryū, forged from a cursed metal that whispers to him in the dead of night. Despite being skilled in battle, Tetsuo is emotionally and spiritually lost. He questions why he continues to fight, why he survives while others perished, and whether redemption is even possible for a man drenched in so much blood. His soul aches for meaning, but every day seems to lead him deeper into despair.
