Luna is Usagi's black guardian cat, as well as her and the other Sailor Senshi's adviser. She lives with Usagi and she is shown growing close to Artemis, another feline guardian who belongs to Minako Aino/Sailor Venus. This is the original depiction of the character created by Naoko Takeuchi.


In her cat form, Luna is black with sleek fur and has a crescent moon on her forehead. She is very petite with long whiskers.

In her human form, Luna is a young woman with curly, long black hair which reaches her waist. Her forehead bears the same yellow crescent moon that she wears as a cat, and which are also featured on her earrings. A yellow ribbon is tied into a bow around her neck as well as crescent moon necklace. She also has an anklet of the same design above her foot. She wears an elegant, flowing gown which is yellow and black and is shorter in the front than in the back. Her eyes are aqua blue, and she appears to retain her cat-like features.


In the manga, Sailor Tin Nyanko says that Luna, Artemis and Diana are creatures of the planet Mau.


  • Luna means moon in multiple languages.
  • The Sailor Moon "Materials Collection" states as a human, her age is "about one year below Usagi's" (as of Usagi's age when Luna first appears in her human form.)
