Their first mystery was technically on their very first day meeting each other, because Eru gets locked into the club room. Hotaru’s quick conclusion about the janitor made Eru want to ask him about solving her personal mystery involving her uncle. They make a big deal about this mystery, so I assumed it would have a recurrence later in the anime, but it never really did (besides being the focal point for their anthology). Anyway, Hotaru helps her out and eventually they end up concluding that her uncle had helped in a revolution for keeping the school festival’s correct amount of days and got expelled for it. He was the scapegoat for the whole ordeal, but really it was others who truly led the revolt. Personally, I thought that whole uprising was stupid (then again I’ve never been one to care for festivals and such.)
