Polite Society is a Youma created by Malachite. In Episode 33, Little Miss Manners, Malachite transfomed an aristocrat who ran the Princess Seminar into Polite Society. Her attacks involved encasing Lita and Amy in wax. Eventually, she was restored to her original form when Sailor Moon used Moon Healing Activation on her. She has a tendency to speak in very polite, ladylike phrases.
- Polite Society is among the Youma that appear in Sailor Moon: Another Story.
