While in her human form, Luna is depicted as a young child. She has blue hair, a trait that is carried over when she transforms into Sailor Luna. She also wears a dress made from yellow and purple fabric and her bracelet, which she uses as her transformation device.
In Act 27 of Pretty Guardian Sailor Moon, Luna is given a human form due to the presentation of the Silver Crystal. Its power also allows her to transform into Sailor Luna, by pulling out a cellphone and pressing the buttons 6-7-2 on it. The senshi seemed confused at first by the appearance of the girl and she only reveals her identity to them when she transforms.
Therefore, Luna is unable to keep her transformation in certain circumstances. For example, if she sneezes or gets knocked out, she automatically reverts to her toy cat form. Also, she is still, in a way, a cat during her human form. This is shown when she is easily scared off by a dog and gets distracted when a bunch of bouncy balls are released in a toy store, much like any other cat would. Her role in the Tsukino family is much like that of Chibiusa's: she appears and no one seems to question it.
- Sailor Luna/Luna Tsukino had one image song in the live-action series: Sweet Little Resistance.
- Sailor Luna in PGSM is a child but in the anime, Luna is an adult in human form.
