Spoiler:

Seems to me that Altena took the prophecies way too seriously which backfired in the end. The Noirs could have been put through trials with different methods while keeping Kirika's memory intact (such methods were also used on different occasions). Mireille would probably never have entered the picture. It doesn't make much sense that Mireille is involved while Altena considered her unfit. Kirika and Chloe made the perfect duo, skillwise, as evidenced in one episode where all three of them were tested. Mireille was pretty much stunned when she saw them in action perfectly attuned to eachother. I still wonder if it was really Altena's intention all along to get Mireille and Kirika teamed up, since she could have avoided this possibility altogether.

I also wonder what happened to Chloe's en Kirika's parents, I have a feeling that Altena had them killed anyway, whether they objected or not, just so there would be no chance of outside influences during their indoctrination. Also wonder what Kirika's real name is although I suppose Kirika may just have accepted her adopted identity in the end.
