Many of the series female antagonists are dressed provocatively.
The Specter Sisters have brief nude scenes when they are healed
In Season 3, both Messiahs are depicted as nude women. There is no graphic genitalia.
The last episode showed Usagi completely nude, but this was done in a mannequin-style rather than in a sexual way.
Several characters often make references. An example of a character would be Minako Aino
Characters are seen wearing short/ cut clothing
A rape scene occurs in season 2. The scene is not mentioned again after the episode.
Characters share beds and homes
The show has a fair amount of fan service, mostly skirts and costumes
Character Ami Mizuno is seen completely naked. This scene is not sexual in anyway, it's supposed to be for purity.
Mild suggestive theme.
A major plot element is the relationship between Sailor Moon and Tuxedo Mask who are reincarnations of a married couple. There is some flirting and kissing in later episodes.
Contains only very mild stylised nudity throughout the course of the series.
Transformation sequences depict the Sailor Guardians nude, however, their bodies are bathed in white. The shape of their breasts and buttocks are occasionally visible. Throughout the second season, several villains undergo a brief purification process in which their naked bodies spin around before returning to their ordinary states. Nipples are depicted in some of these sequences, however, any such nudity is very brief and presented in a fantastical, non-eroticised fashion.
Also contains infrequent "fan-service" (shots common in anime) in the form of panty shots and the like. Such shots are usually incidental and are not prolonged.
One episode is shown Usagi naked holding luna but this is not sexual.
Also contains infrequent very mild naturalistic nudity.
Chibiusa has some panty shots which is kinda creepy considering she's only a young girl.
Esmurade is scene once in the bath, not that sexual, though.
