Yaten, Kou

夜天光

Kou Yaten is frequently aloof and cynical about everything. He dislikes socializing or participating in sports. His remarks are often sharp and blunt, which further isolates him from the world. In one episode, the other Starlights even reprimand Yaten for behaving in a manner that might reduce their fanbase. However, he and Luna get along well. At one point during that episode, Luna inspires him to keep fighting.
In the anime, he possesses the highest spiritual awareness among the Starlights, allowing him to detect when Starseeds are taken by Sailor Galaxia. He views humans as untrustworthy and wants to find Princess Kakyuu so they can leave Earth as quickly as possible. This becomes clearer when they discover that Usagi is Sailor Moon. Yaten believes that Seiya should stay away from Usagi, despite the shared wish of Princess Kakyuu and the Guardian Senshi for them all to work together. His view is shared by Taiki, as well as Sailors Uranus and Neptune.
