These are my next ones
hypotheses:
1. In the Dragon Ball series, Vegeta before joining the Z Warriors, wanted to destroy the world, but eventually changed his path. someone's help in destroying the world of demons, it would be possible for Amy Kiriwo to change her path as Vegeta had done.
2. Baal the thunder lord of the 13 crowns but also the shadow leader of the terrorist organization called the six fingers. I think it would be possible for Baal to stab Amy Kiriwo in the back (as far as I can remember in the back I saw it in other parts), but also the fact that Baal could do it in such a way as to stage this to Azazel Henri since he is the head of security of Demon Border Control this being from his perspective Baal would have the perfect coverage.
3. I compare Ameri and Henri as Kitsune demons in a way.
