The Forest of Drizzling Rain

After the sudden death of her parents, a young woman named Shiori Kanzaki finds a picture of a man that she believes to be her grandfather, and travels to Azaka Village, where he was apparently from, in hopes of meeting him. However, when she arrives, she learns that her grandfather has already passed on, and the family manor converted to a museum. There she meets Sakuma, a middle school girl who tends to get herself in trouble; Officer Mochizuki, the cop who usually busts Sakuma; and Suga, the strange manager of the museum who only communicates in written memos.
