I am going to say I haven't read it because I can't read Japanese, however I have read the summary and read all the translated novels so I think I have enough information to form an opinion.
So we have Bell, once again outcasted by the citizens of the town, fighting to help protect the monsters that adventurers have sworn to kill.
And at the end...he just goes back. I'm I the only one who feels that Bell not going rogue or at least showing some contempt for Orario, adventurers, the Guild, or even the gods?
I know that Bell's deal is that he is pure and naive but it's really getting to me. He is constantly slighted by almost everyone in the series and he just takes it. Unless it involves Hestia, to which he will go balistic.
