Three Lights

The Three Lights in Crystal

The Three Lights (スリーライツ) were the singing teen idol group formed by Kou Seiya, Kou Taiki, and Kou Yaten during the Stars season of the anime, the Stars arc of the manga, and Sailor Moon Cosmos. The trio formed the group with the intention of contacting their missing princess, Princess Kakyuu.

During the final arcs of the anime, manga, and Crystal series, the group was shown performing concerts of their music, with plenty of screaming fans adoring them. In the anime, the group was often shown performing the song "Nagareboshi He" at their concerts, after it first appeared in episode 185. In that continuity, the group was also noted for having an extremely large fan club, of which all four Inner Senshi were members.

The group eventually disbanded in anime episode 195, as they had found their princess and no longer needed to continue the search. Sailor Tin Nyanko used the group's farewell concert as an opportunity to attack the Sailor Senshi for their Star Seeds.
