Something is wrong in town. People are disappearing and the people who remain have gaps where their memories of those missing people should be. Hinata Yuzuzaka takes it upon herself to investigate. The investigation is complicated almost immediately when she becomes the victim of a mysterious phone application designed to wipe memory — she wakes periodically to find that time has moved without her knowing what happened during it. Help Hinata track down the source of the application and the hypnosis that is consuming her world, before she loses enough of herself that tracking anything becomes impossible.
