Kyoko Hayase (速瀬 京子 Hayase Kyoko) is a shuttle pilot who is Shou Tatsumi's superior. She received the Beast-Demon Hunter armor and became Sieg-Jeanne.
When the GoGo-V rescue her shuttle from a tornado caused by Tornedeus, she is able to recognize Shou's voice on the communications system because the GoGo-V were using the same radio frequency. Afterwards she wanted to join the GoGo-V but could not because Mondo Tatsumi only designed the team for five people. So instead she occasionally aids the GoGo-V in anyway she can and never got in their way. In the GoGo-V Movie she briefly gained the Sieg Tector armor from Beast-Demon Hunter Sieg before he died.
Using the power, she became Sieg-Jeanne, transforming with the call of "Sieg Tector!", armed with the Sieg Blaster. By transferring all the Demon Hunter powers to the Victory Robo, she helped the GoGo-V destroy Golomois.
In the finale, Kyoko played an important role. Not only did she confirm that Grand Witch Grandiene was still alive (after the GoGo-V defeated her with the Max Victory Robo), after noticing her when she went up into orbit in a shuttle, and then reporting it to the GoGo-V after Kyoko had returned to Earth.
Later when Mondo sent her to give the GoGo-V the information on where to find the Max Victory Robo Sigma Project, and just after she barely escaped the destruction of BayArea55, Kyoko received the phone call from Ritsuko Tatsumi who had just come out of her coma and was able write down the call back number. Kyoko was able to pass both pieces of information on to Daimon Tatsumi and Matsuri Tatsumi which would be instrumental to the GoGo-V's final victory.
Kyoko did not fight in the Great Legend War because she had lost her powers.
- Sieg Blaster
- Kyoko had a Power Rangers counterpart named Nancy Cooper who, unlike Kyoko, appeared for a single episode of Lightspeed Rescue (based off the footage from Kyoko's original appearance). She was not involved with the main plot.
- She is similar to the Magne Warrior in Bioman, in that both wanted to join the Ranger Team, and were turned down only to get temporary Ranger powers.
