Sailor Star Healer is the shortest of the Sailor Starlights. She has long white hair tied into a long ponytail, identical to the other Starlights. She has green eyes. Her sailor fuku, identical to the other Starlights, is a navy blue two piece outfit, consisting of a bikini-like top and hotpants. She wears knee-length boots and elbow-length gloves. She wears a golden beaded tiara, beaded belts on her waist and golden star earrings. Her secondary color is light green. She also wears a light green criss-cross choker and green bracelets on her wrists.
Sailor Star Healer, along with Fighter and Maker, first appear at the end of Act 50, where she destroys Sailor Iron Mouse single-handedly with her Star Sensitive Inferno attack. She later introduces herself along with the other Starlights towards the end of Act 51, after Sailor Aluminum Seiren is destroyed.
All three of them has been a constant source of help for Sailor Moon whenever she was close to defeat. They, along with Princess Kakyuu, went with Eternal Sailor Moon to Sagittarius Zero Star. However, once they reach their destination, they reach a desert with a mysterious cloaked figure on a boat on the sand. Once they enter the boat, the desert turns to water and all of them drown. The figure, revealed to be Sailor Lethe, prepares to kill Eternal Sailor Moon when she and Mnemosyne are destroyed by Sailor Chi and Sailor Phi. Both of them absorb the Sailor Crystals from the still unconscious Sailor Starlights, resulting in their death.
Naoko Takeuchi originally designed Healer and the other Starlights without their ponytails, but they were later added after she came to know that short-haired dolls were difficult to make.
