In her unchanging daily life, a girl is tormented every night by the same recurring nightmare. Trapped in a day that repeats like the swing of a pendulum, she seeks a way to break free. In desperation, she makes a wish to the snowdrop—for a “tomorrow”. But that simple wish begins to distort her world, drawing her into a new spiral of fear and unease… From Kei Sanbe, the creator of ERASED (Boku dake ga Inai Machi) and The Island of Hōzuki, comes a haunting tale of psychological turmoil and looping dread— the beginning of a pendulum-horror story steeped in anxiety and mystery.
