Attention, major spoiler (!)

If I have understood everything correct, the sitution would be as follows:

It is hinted that Luna Clear (Ikusa Megami Zero, Ikusa Megami Verita) is the first reincarnation of Satia. Celica seems to remember scenes with her, that had never happend with her, but with Satia.

Later it is hinted, that Roca Luscort (Ikusa Megami, Ikusa Megami 2, Ikusa Megami Memoria) is the reincarnation of Luna Clear. As such she would be the reincarnation of Satia aswell.
