A solitary house stands in a desolate landscape. Here resides a petite girl with pigtails, unconstrained by her isolation. She rarely encounters anyone to meet or interact with, except for occasional masked visitors from an unknown place. Her only companions are the inanimate objects around her. They recount stories about themselves, the girl, and the static surroundings they observe day after day—all while she remains unaware of their sentience. One day, the monotony is broken when the girl meets someone who offers her a choice capable of altering many fates, including her own.
