Rakuyou

Kaoru, a university student, loses his father to suicide, although he feels suspicious about the circumstances. He is worried about living expenses, and he considers moving to an apartment and working part-time so he can continue studying. As a strange coincidence, an attorney from his dead mother's estate shows up and states that he inherited a house in the countryside. He is allowed to live off the estate and not worry about the expenses, but only if he changes his last name to his mother's last name. He agrees and moves there. People living in the village act very cold and scared towards him and he is asked to avoid the mountain and its temple. As he finds out more about the secrets of the mountain and his family line, something is just waiting to happen in this strange place......
