Takakage is disturbed by a peculiar dream, apparently of a past life as a soldier during Japan's Sengoku Era. In that existence, he loved the miko Ayame, although their romance was doomed by war. Now, in his current life, he receives a prophecy that he will encounter the woman of his dreams. Takakage, a college student, has been experiencing strange dreams recently. In them, a young shrine priestess named Ayame promises to marry a young soldier named Genshiro, who looks like Takakage, the night before he is sent to battle. Takakage discovers a maiden who resembles the woman from his dreams. With the assistance of her, his sister, and his fortune-telling friend, he attempts to uncover the truth about their, and his, true origins.
