Outside of having the hero punished "on-screen" this pretty much wrapped up everything that the story has introduced so far right? I mean, the whole war against the demons was manufactured by the king, so unless this just becomes a fluffy story about their lives continuing, which wouldn't be too bad considering how enjoyable it has been, I'm going to guess it's either ending shortly or some new threat is about to come about.
If that's the case I hope it isn't the generic "heaven wants demons dead so now angels are coming to do it/church is evil" cliche.
