Afterwards she left, donning a white garb, she left her Ultra Ring and her connection to Ace for Seiji, wishing both Ace and Seiji goodbye as she left the Earth. She is replaced by another crew member named Minawa Noriko.

Ultraman Taro
During Taro's time on Earth, the invading monster Mochiron had come and disturbed the Earth on a day known as "Mochi Day" and refused to leave until he had consumed enough Mochi to satisfy himself. Working alongside Ultraman Taro and Father of Ultra, Yuko grew to giant proportions to help them in making enough Mochi to satisfy Mochiron. Once the monster was full, Yuko and Father of Ultra carried him off into space.

Later on, during the Ultraman Mebius' stay on Earth, she would appear to an older Seiji, fighting again as Ace, to help Crew Guys Japan, against Lunatyx on the moon.
