「三人の時計守」

The three clock keepers are the first of the Seven Mysteries. 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.

The clock keepers are able to control time. Kako and Mirai have the ability to turn back and move time forward respectively. As a contractor, Akane can stop time for five minutes up to three times a day. He notes that if he goes an entire school day without any incidents, he is able to use it for fifteen minutes at a time.

Obviously, The First School Mystery oversees the "Time" aspect of Kamome Academy. In fact, when the Big Clock at The Sealed Auditorium was destroyed, the entire academy's time was stopped, which also opened the Clock Keeper's boundary.

Boundary

Until Chapter 106, the boundary of School Mystery Number 1 was unknown. And until Chapter 110, their Yorishiro remains unknown.

It is noted Hanako does not know where their boundary is located at due to a bad first impression. He had said the Clock Keepers "can do all the pervy stuff [they] want" with their powers, causing the keepers to "never want to see him again" and refuse to tell him where their boundary was.

In Chapter 103, Natsuhiko claims that the location of School Mystery Number 1's boundary has been found, thanks to having planted the tsueshiro on Akane earlier. In the following chapter, Natsuhiko himself goes to the mechanical room of the Big Clock of The Sealed Auditorium, and spills his blood, which later coats and covers the entire mechanical workings. All the while, Natsuhiko claimed in the form of a rumor that his blood can instantly destroy any supernatural. Thus, it implies that the Clock Keeper's Boundary, or its entrance has something to do with the Big Clock at The Sealed Auditorium that they control in the first place. It is revealed that only when the Big Clock is destroyed and time for Kamome Gakuen is stopped, that the entrance to the Boundary is revealed and thus, can be accessed.

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 process.

In Chapter 110, the Heart of the boundary is revealed after Kako used the Key containing the Clock Keepers' Yorishiro to unlock the door that leads to it. The Heart of the boundary is at a sleepy western-styled town in the middle of a snowy environment. The town is populated by clockwork doll-like people that speak an entirely foreign language, and one of the houses within contains Kako's worshop where he fixed up Mirai while discussing with Akane about the "Root of the Problem". It is also implied that both Kako and Mirai hail from the same town and are of the same species as the inhabitants there.

...Have you heard the rumor?

It's school mystery number oneー The three clock keepers.

There's a big, big old clock somewhere in the school.

That clock is time itselfー the time that flows through the school.

If you move the hands of that clock, the school's time is yours to command.

But you see...

...There are guards watching over the big clock.

They are the three clock keepers who represent past, present, and future.

If anyone touches the clock without their permission...

...The three clock keepers will steal the time from that person's life...!

Trivia

• The Clock Keepers are the only School Mystery to have more than a single representative.
• Aoi Akane's hairstyle as a Clock Keeper is inspired by Kako's own hairstyle. This is because Mirai wanted his hair to match with Kakos. Akane, while annoyed by it admitted that it has a "scholarly" feel to it, right after Mirai asked if he wanted his hair to match with hers instead.
