A 15 year old boy named Hiroshi Kuzumi recently moved into a new town in the mountains. The town is separated into new and old streets by a river and many mysterious local cultures still remain. The towns people are unusually friendly to him but one person kept her distance from him: class committee member Kushinada Nemuru. In their few encounters she gave him a word of advice: "Stay away from the old streets."
Hiroshi learns about the town's local traditions and legends, most prominently the ones about the local Wolf Spirits. However, something mysterious goes on in the background; people mysteriously "move away" and students suddenly "transfer schools" while none of the locals pay any attention. Hiroshi initially tries to ignore it, but he soon sees a girl with an enormous scythe along with people in strange masks kill someone that was written off to have "moved away" the next day. Hiroshi is soon drawn into the dark secrets long hidden by the townsfolk and uncovers a plot to destroy the town.
