Yaten Kou is one of the members of the Three Lights idol group, and is the civilian identity of Sailor Star Healer.



Yaten is the shortest of her group and has long silver hair tied into a low ponytail. She also has green eyes and wears emerald earrings. As a member of the Three Lights, she wears a blue shirt with a red tie, and a light blue coat with a yellow rose, and light blue pants.


Sailor Star Healer's sailor uniform consisted of a black two piece outfit, consisting of a bikini-like top and shorts. She wears thigh-length boots and bicep-length gloves. She wears a golden beaded tiara, green 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.


In the original anime, Yaten is more withdrawn and aloof, preferring to spend time reading alone and focusing on completing the mission she, Seiya, and Taiki came to Earth to accomplish. She expresses a disinterest in the people of Earth, frustrated by how they claim to love her without actually knowing her. Yaten takes her responsibility as a Sailor Soldier very seriously, so seriously, that she chastised Minako when she appeared to be placing more importance on being in an idol competition than her responsibilities as one of Earth's guardians.


Sailor Moon Sailor Stars

Sailor Star Healer first appears in episode 173. She came to Earth along with the other Starlights to find their princess after their homeworld was destroyed by Sailor Galaxia. She became a student in Juuban High school, and also became a member of the Three Lights, which becomes famous across Japan. After Kakyuu was killed, she teamed up with her fellow Senshi and attacked Galaxia, she also stood with Sailor Moon to protect her. After Galaxia was healed, Healer returned with the other Starlights and Kakyuu to restore their homeworld.

She has the most spiritual awareness among the group, since she is able to tell when starseeds are taken by Galaxia or her minions. She does not like humans, viewing them as untrustworthy, and wants to find Kakyuu fast, so they can leave Earth quickly. Her opinion about humans becomes more strong when Usagi is revealed as Sailor Moon, and tries to stay away from her. But, nearing the end, she changes her point of view and stays beside Sailor Moon to protect her, saying that, "A girl with such warm light isn't supposed to disappear."
