Ryoko Hoshi (星涼子 Hoshi Ryōko) is Yullian's human form.
Yullian took on human form when she traveled to Earth to warn 80 about the arrival of King Galtan. The members of UGM gave her the name 'Ryoko Hoshi', when she was suffering from amnesia. She later joined UGM when its only female member, Emi Jouno, was killed by one of the Alien Galagala. She finally turned back into Yullian in episode 49 of Ultraman 80.
