Skydain is the red jet-like younger sister of the Kyodain. Like her brother, she gains her own personality and wants to rebel against humanity. As Kyodain's human identity, Shizuka Shiroyama is Saeba's personal secretary. Skydain, Groundain, and Black Knight were created by Professor Blink; but the Kyodain went rogue and attacked the professor. The professor proceeded to seal their power in the satellite they were in, forcing the Kyodain to assume weak human forms.
