Sayo

A young girl who took Luka Millfy's GokaiYellow powers when she was turned into a doll.

Biography
She was helping to prepare for a Christmas party along with her brother Seiji, when Seiji fell off a ladder, when Gai saved him. When the party was attacked by Bibaboo of the Imperial Guard, Seiji was turned into a doll. Bibaboo used his staff to turn the girl into a doll, but Gai protects her and is turned into a doll. After the Gokaigers arrive and drive off Bibaboo, the girl feels very upset and responsible over the loss of her brother. However Luka calms her down and the girl gives Luka a fake doll to fool Bibaboo, but Bibaboo is not fooled by it and turns Luka into a doll. The girl turns into GokaiYellow in Luka's place and fights Bibaboo, eventually getting his staff, restoring all the doll-transformed people back to normal. She gives Luka back her Gokai Cellular and Ranger Key, leaving the Gokaigers to defeat Bibaboo. After Bibaboo is defeated, she celebrates Christmas at the Christmas party with Seiji, the Gokaigers and other people.
