The story follows Kōnin, a charismatic senior who enrolls at Seika Jogakuin under the guise of a transfer student. While appearing aloof, he is secretly tasked by the school’s “council of elders” to investigate a series of odd occurrences—missing textbooks, unexplained power outages, and a mysterious graffiti that reads “Sao Ojisan.” seika jogakuin kounin sao ojisan 7 updated

Enter Sao Ojisan, an eccentric older gentleman who claims to be the school’s retired janitor, yet displays an uncanny knowledge of the academy’s hidden history. He becomes Kōnin’s reluctant ally, providing cryptic hints and comedic interludes while wielding an old‑fashioned pocket watch that seems to affect time in subtle ways.

Together, they uncover a clandestine club of alumni who use the school’s old ventilation system to smuggle rare artifacts. As the duo delves deeper, they discover that the “Sao Ojisan” moniker is more than a nickname—it is the key to a decades‑old secret society that once protected the academy from external threats.
