A gentle story about girl learning about the world and people. Due to the job demands of her parents, who repair old buildings and works of art for a living, nine-year old Mou Yuu has travelled all the way from the city to a rural village. In this village, where the lush greenery of nature has been preserved, Yuu makes new friends and has many adventures with them. Perhaps because of her heritage, or simply because she is in such close contact with nature, she also encounters the supernatural and mysteries that cannot be explained.
