A few corrections for you, Xanderfox:
- The robotic villain who raised Astronema was named "Ecliptor"
- Karone, not Carron
- Tenaya-7, not Tanya
- Katherine "Kat" Hillard was a real human girl who was put under a spell by Rita to become a cat (and briefly the kitsune monster you mentioned). She always had a past and family.
- Rita becoming the Mystic Mother was thrown in by the production team because both were played by Machiko Soga. It's never really explained how she got her powers back...
