text: Yaten Kou, also known as Sailor Star Healer, is an alien from a distant system who came to Earth in hope of finding her princess.
  
  Yaten, who appears only in the last season or Manga arc, is also a part of a band known mostly as the "Three lights," made up of Seiya Kou and Taiki Kou, all of whom are aliens and Sailor Soldiers; Kou, some fans speculate, as being all of their first names, though most believe otherwise.
  
  
  == In the anime ==
  In the anime, Yaten is shown with an obnoxious, self-centered attitude. He cares for nothing but finding their missing princess, whom they spend most of the show looking for, and does not wish to join forces with the other soldiers.
  
  He finds Earth girls mostly annoying because of their obsessions and recieves tons of fanmail everyday, which he throws away. However, in episode 178 "Luna Saw it, Idol Yaten's real face," Luna discovers a different side of Yaten.
