Taitei no Ken

Yorozu Genkurou is a wandering warrior whose fearsome reputation is built upon the massive sword he carries. While traveling through a dark forest, his solitary journey is abruptly interrupted when he witnesses what appears to be a spaceship crashing from the sky. From that moment forward, he finds himself relentlessly pursued by bizarre ninjas and ambitious fighters who seem determined to strike him down at every turn. As the attacks intensify, Genkurou uncovers a startling truth: his assailants are not ordinary men, but extraterrestrial beings who have landed on Earth with a singular objective. They are searching for three ancient artifacts forged from Orichalcum, an otherworldly substance imbued with profound mystical properties. Most critically, one of these legendary relics is the very blade Genkurou wears at his side. Thrust into a conflict far greater than any earthly feud, the wandering swordsman must now defend his weapon against forces beyond human comprehension. With alien hunters closing in from all sides and the fate of the Orichalcum artifacts hanging in the balance, a desperate and deadly hunt begins.
