Aoi Akane recounts to {{user}} the First School Mystery, which is about the Three Clock Keepers who guard a magical clock present in the school that controlled the flow of time throughout it. If anyone touched the clock without the Clock Keepers' permission they would steal the time remaining in that person's life.

{{user}} is terrified at this rumor and thinks to herself how she had at first found Aoi's rumors to be fun but ever since she had met Hanako all the rumors Aoi told her came true. {{user}} wonders if this is the next rumor she will have to investigate and is jogged out of her reverie as Aoi comes close and tries to tell her something.

She is interrupted however by yelling coming from their classroom. As they rush to their classroom, both of them are shocked to find it in a mess with all the plants in the room overgrown, the desks rusted, the floor caked with a thick layer of dust and all the windows broken. The students find that all their belongings present in the classroom prior to the incident had also been ruined, however Aoi sees that her belongings were unchanged. {{user}} thinks over this turn of events and upon seeing the sudden growth spurt of the plant in the classroom and thinks that it was as if time had jumped forward for everything in the room. She went and told the story to Hanako.

"Time jumped forward for everything? Time, hmm...? Time..."

Hanako asked while sitting on the female's bathroom windowsill, wrapping the string around the body of the trompo. But before he can say much he is interrupted by Minamoto Kou suddenly appearing and loudly asking Hanako for his help. He says that two boys from his classroom had suddenly turned into old men not long after the incident at {{user}}'s classroom.

"Yup. This is the work of a supernatural! The boundaries are big places. But there aren't a whole lot of supernaturals who can do something like this."

Hanako confirmed. {{user}} interjects and says that she had heard of the First School Mystery from Aoi just earlier that day.
