Tomo is a student at Tokinodai Gakuen, a small traditional liberal arts boarding school that was built in the Meiji era. However, he has a secret – he has a clock passed down from him by his grandmother which allows him to control time – and he uses this ability to make his school life enjoyable. One time, Tomo found out that there is a link between the clock and the seven mysteries of the school. If one obtains any of the seven clocks linked to the seven mysteries, they will be able to use various time-manipulating powers. His interest perked, Tomo set out after school to the old school building to begin his search. During his search, he meets various girls and together they unlock one of the seven mysteries. They arrive at a space where time has stopped and find a girl in traditional dress sleeping there. She used to be able to manipulate time, but now she has lost those abilities. Will they be able to find all the clocks, awaken the sleeping girl and return her to her time?
