A young boy called Lubicchi is filled with sorrow after losing his best friend, Poupelle. Then he accidentally wanders into a mysterious realm that governs time. In this world, any clock that stops ticking is immediately discarded. But one strange tower remains standing despite its clock being frozen at 11:59. Lubicchi discovers that the only way to return to his own world is to restart this stopped clock. Together with his companion, Fluff, he begins to unravel the mystery of the clock tower. During his journey, he encounters Gus, a man who has kept the faith and waited for a hundred years, and Nagi, a tree spirit who once took human form. When Lubicchi finally regains the courage to believe, a miracle occurs on Halloween night.
