Janitor Ghost

A kindly janitor's ghost that still considers himself employed at Karasumori Academy. Despite his having been dead almost fifty years, he has yet to pass on, and Yoshimori seems in no rush to force him. Yurina Kanda is the only other student to have seen him.

Appearance
He is a short, round older man, and wears glasses.

Personality
Despite being dead for so long, he only seems to want to clean up the school, and is in no hurry to pass on, despite repeated urgings from Yoshimori.

Trivia

 * The janitor ghost is most likely the anime version of Gen-san, the ghost who frequently appears near the school gardens.
