Aragami

A samurai wakes in a remote temple after a storm to find his wounds closed and his wounded comrade dead. The swordsman who shelters him, along with a silent young woman (Kanae Uotani), is Aragami (Masaya Katō), once known as Miyamoto Musashi, and he has given the samurai (Takao Osawa) immortality. Kitamura made it in a week, with two fighters and one setting, framing the temple's wooden halls like a stage.
