Also known as: 夜天光
The white-haired member of the Three Lights who transforms into Sailor Star Healer. Yaten is often aloof and wishes to find Princess Kakyuu as soon as possible so they can leave Earth. The treatment of the Sailor Starlights radically differs between the original manga and the 90s anime, with the trio being able to transform into men in the anime when this did not exist in the manga.
She is voiced by Sakamoto Chika in the 90s anime, and by Sakura Ayane in Bishoujo Senshi Sailor Moon Crystal.
