Akane, a member of her school's newspaper club, has a new assignment: write about the "haunted" places in her sprawling town. She decides to invite the new (and seemingly lonely) transfer student to come with her on her ghost hunt, sparking a friendship between them. As the two girls embark on their own little adventure down labyrinthian staircases, across cryptic sidestreets, and through dark and foreboding tunnels, they discover that there might be some truth to all the spooky stories, after all!
