Naoko Takeuchi noted a few details about Diana in the Materials Collection; she was cute, talkative, impertinent and playful.
Diana is described as being "as fragile as a teardrop". She has thin, light blue wings and wears a short lemon-yellow lace dress. Diana also dons star and moon earrings and bracelets and wears her blonde hair in odangos like Usagi.
- Naoko stated in her sketches that Diana and Luna would not get along. Ironically, Luna's kitten is named after her.
- It is unknown why Diana was cut from the story.
- It is said that Diana was originally also supposed to be Sailor Moon's Power Guardian.
