Sakazaki Aoi

She was hired as a janitor at the school a little earlier than the main character and lives in the janitor's office. She is a man-crazy person who loves to drink, hit, and eat (men). She has known the board chairman for a long time.

She has a feminine body that does not look like a janitor from the outside, and she wears flashy clothes. Although she claims to be a janitor, it is unclear whether she actually does her job. There is a rumor that the school janitor is “poisoning students on their way home from club activities at night,” but no one knows the truth of this rumor.

Later, the principal asks her to investigate the main protagonist, and she begins to snoop around him.
