So Mikuni, the evil psychokinetic empress, is the Moon (she lives in the Moon Palace after all) and if the guys who work with the evil bitch are right, Kuniko is the Sun.

I don't know if I am jumping to conclusions, but they almost made it seem like the evil bitch was Kuniko's mother. Then again, the "child" mentioned in the dream sequence might not be Kuniko, but rather that boy in the room with all the eyes.
