Kurozuka

Kurozuka is an anime adaptation of Takashi Noguchi's manga, which in turn is based on Baku Yumemakura's novel. The story follows Minamoto no Yoshitsune, a 12th-century Japanese military leader who flees to the mountains after his defeat by his brother Minamoto no Yoritomo, the first Shogun of Japan. There, he encounters Kuromitsu, a mysterious woman living in a hermitage who harbors a dark secret: he is immortal and will live for a thousand years.
