Evil bishops have become such a common cliche among isekai and fantasy manga that I'm genuinely surprised Bagley isn't one of them despite how he looks.
THE PENETRATOR! Sorry... had to do that...
But yeah, its always nice to see a more ambigious figure than in normal Isekais, i like it when (somewhat) assholes are the good guys instead of a clicheé enemy
And overall: So nice that a damn good LN gets a damn good manga, most often thats not the case... :x
