I really liked Satanachia too, but I think she is more Eidolon than Kamihime. I feel sorry for Alyssa, but a playable version of Alyssa destroy her place as the Butt Monkey of the game.
As for Kamihime ascension... SR version of Perun, and SSR of Nyarlathotep and Rami-Rami will have my Seal of Approval. I know there will be a Thunder version of Nya, but I think she is SR still.
