Sailor Luna appeared for the first time at the end of Act 26, confronting Dark Mercury. Once Sailor Moon awoke as the Princess with the Ginzuishou, Luna gained new powers that allowed her to transform into a human and back to her plush form. Luna maintains her catlike habits while in human form, although she picked up quite a sweet tooth. Luna first appeared as a mysterious young girl to the other girls. By dialing 6-7-2 on her Lunatia-S and shouting "Luna Prism Power," she transformed into a Sailor Senshi like the others, becoming Sailor Luna. She called herself the Senshi of small and cute things, her power seemed to be based on the 'candy' element. Like Usagi, Luna wields a Moonlight Stick and can transform it into a large folding fan when she wants to attack directly. She can also change it into a Golden Fan and a catching net. Sometimes she reverted back to plushie form involuntarily, such as when she sneezed, was surprised, or lost consciousness.

In the Special Act, Luna appeared in both her human and plushie forms. She is the only one of the Senshi who is still able to transform without outside assistance, although it was unexplained why she still had her powers when the others lost theirs. She is also shown living mainly as a human with Usagi's family, with whom she gets along quite well, though she still takes on her cat form when necessary. She is also shown to have taken on some of the personality traits of Usagi and her mother, such as acting in the same melodramatic manner when waking up in the morning.
