Love Life: Seiya really loved Serena, but felt that Serena�s boyfriend was very lucky. Seiya wished that they had met each other sooner

      Seiya transferred to Serena's High School, and joined the American football team.  Also a vocalist in the idol group �Three Lights� . Seiya became good friends with Serena, and cared for her a lot. Seiya also knew that Serena has secrets to hide. One time Seiya told her that every person on earth had a glittering star inside themselves, and that the stronger the star, the brighter the glitter. Seiya then said that Serena's glitter was very bright. When Yaten and Taiki found out Serena was Eternal Sailor Moon, they didn't want Seiya to see her again. The Outer Scouts were going to attack them if Seiya didn't stay away from Serena, which Seiya reluctantly agreed to.

     Sailor Star Fighter acts as the leader of the Sailor Starlights. Fighter wants revenge on Galaxia for destroying the Starlight's planet, and is trying to find the Princess of their former planet who had escaped to earth. Fighter was very happy when Princess Fireball appeared to them, but felt torn between Serena and the Princess. When Princess Fireball was killed, Fighter thought there was no more reason to live, but Chibi Chibi Moon reminded the Starlights that the Inner Scouts had sacrified themselves for the Starlights. Fighter decided to stop Galaxia.

     After Galaxia was stopped, Seiya, the Starlights and Princess Fireball returned to their home planet.
