I am somewhat disappointed with the ending. It was great somewhere up until the human king but then it dropped in story quality in favor of Naruto-esque escalation, which was quite uncalled for - especially since from the Empire's perspective it's a rather large, but still quite backwater, conflict. And "everyone lives" is an underwhelming ending. Could have killed a couple of secondary characters tbh.
Ah well, you take what you can get.
