Lots of stuff to sort out in the last story part. Doctor became unusually passionate when it comes to letting young operators fight. Both Kal and Rosmontis said there's no other way for some of them and Rosmontis especially is portrayed as this frightening force of nature when she goes all out.
The part about Amiya pretending to appear more mature than she is also hit the right spot.
And of course there is also a prophesy now. Why wouldn't there be one? The Lord of Fiends doesn't ring any bells, though it could be the Regent from Darknights. Or Amiya. I'm not sure yet.
Also foreshadowing?
