Sword of the Demon Hunter: Kijin Gentosho

For generations, a shrine has stood in the mountain village of Kadono, and for each generation the shrine has had an Itsukihime--its shrine maiden--and the maiden has had her guardian. During the Edo period, a young man named Jinta protects the town and the Itsukihime. When he confronts a strange demon in the nearby forest, it tells him that in the distant future a Demon God will threaten all people, everywhere, and it claims that the Demon God's rise to power springs from this very time and place, in the village of Kadono.

Jinta's path is set: in one hundred and seventy years, he will face the Demon God and attempt to prevent a catastrophe. He has changed his name to Jinya and left his adopted home behind. It is the Bakumatsu period, and the city of Edo is bristling with unease. As a demon hunter in the city, Jinya encounters a warrior in search of his missing brother and finds demons hiding among the people. Among these meetings and partings, he seeks a reason to wield his blade.
