No, I still firmly believe she is really a demon, and she was summoned when in high school, F Chopper Koga as she was unhappy with her old band and sought vengeance. So she summoned Hana, who instead of destroying the old band formed a new group with her. As such we now have the awesomeness of Gacharic Spin, and the music that can steal our souls. Evidence of the fact she is a demon can be heard if you have ever heard Hana do a growl on a song.
I have another theory some where in japan there is a secrete underground research facility making androids and there girl musicians, its the only way i can see how there doing it . LOL
