The Edo Period was a time when humans still had dangerous encounters with demons who ran rampant throughout the land. In a remote village in the mountains known as Kadono, the traditional shrine maiden called “Itsukihime” would unfortunately be targeted by demons.
Despite being an outsider, a young man known as Jinta is tasked with the duty of protecting the shrine maiden. One day, while hunting down a demon sighted in a nearby forest, he comes across a mysterious demon who claims to have seen into the far future — from the Edo Period all the way to the modern Heisei Era.
Jinta ends up on a journey spanning across time, constantly forced to question what it means to wield a sword and what it means to be a demon and to be a human.
