Elegant, sophisticated, though sometimes cold, she can use her talisman to predict events of a close future.

- She lives with Haruka in the same house, in it she's showing to be touchy-feely with her.
- The first ending of Sailor Moon Crystal III features her love relationship with Sailor Uranus, clarifying that she have been led by romantic attraction to Haruka.
- For some reason, Her jealousy of Haruka getting close to Usagi by kissing her secretly "only for fun" as it noted by her is not showing clearly until Haruka discovered while embracing her in their house the lonely expression she wears, and her slightly sad eyes Haruka could only discover, due for her flirting with Usagi.
