I just finished season 2 and I'm not sure I totally understand Chloe after Ep 6. I haven't watched any of the FSN series except the Illya spinoff. Do the others explain this more?
From what I understand,
she was supposed to be the holy grail and was sealed away inside Illya. However, they never explain why this was done or what this means. Is it explained more in the main series or is it just kind of a mystery?
Iri explains as much as you need to know.
Listen to best mom.
Watch it for the lolis and don't think too much about it.
