Sayuri

Sayuri is a young girl whose father was kidnapped by a UFO.

History
One night, while serving her father a drink, a UFO flew from the sky and abducted her father. Later, it was shown the Dazaan Army was holding him hostage to work on a scheme to get brilliant scientists to develop a substitute for the Key Energy to activate the Energy Heart. The UFO boy scouts then came up with a plan to disguise Miki as Sayuri, wearing a transmitter so they could get Dr. Ina's location.

It worked, and she was shortly reunited with her father after Dai Apolon fought a giant fish robot.
