It is the fourth school mystery to be introduced in the series. They are the first school mystery to be seen independently outside of their boundary and unrelated to their rumor. Unlike the other school mysteries, the Clock Keepers consist of three members — Kako, Mirai and Akane. They represent past, present and future. Akane was tricked into forming a contract with the Clock Keepers after falling for a scheme they orchestrated. He is now currently in a 6-year-long contract with them, until his graduation. boundary: In Chapter 106, School Mystery Number 1's boundary is revealed for the first time. It is an endless labyrinth that comprises of a series of gears, screws, lifts, and other clockwork-related parts that are constantly moving about. It also has multiple tower-shaped or birdbox-shaped structures scattered throughout. Time flows differently in the boundary, as even if Kamome Gakuen's time was stopped a chapter earlier, time still flows the same in the boundary. It is also home to several clockwork owl-like guardians that protect the boundary from intruders by siphoning the time off them, which reverts them to a younger or earlier phase of their time in the processes.
