Ryo, a young ronin, and his sister, Akari, are on a journey to find an elusive samurai with white hair who they believe will be able to help them. Following a lead into a small village, troubles arise when Ryo's sword gets stolen and Akari's identity as a yokai is exposed. The siblings are saved by Suzuka, one of the villagers, who recognizes they are not a threat. She agrees to tell them about the white-haired samurai, as long as they do something for her first.
