The Asuka region is the birthplace of Japan. In ancient times, there were three small mountains that people believed were inhabited by gods. They were Mt. Unebi, Mt. Miminashi, and Mt. Kagu, and they still stand. Time has passed into the present. Takumi and Kayoko, inheriting the unfulfilled hopes of their grandparents, live out their lives. Their tale continues a story of the ages, representing the uncountable souls that have accumulated in this land. Kawase tells a story of romance and ghosts.
