The moral of this anime title seems to be: god bad, pigs good, marry monsters, save corrupt cities, serve demons. The series is not entirely without merit, many characters are likeable despite major flaws, but this anime spends so much time exploring moral gray areas that I can not in good conscience recommend this. This appears to be what is called "slow burn corruption", where the intent is to slowly corrupt the viewer. If it starts out looking like satanism and bestiality, I won't be surprised if ends up looking like incest and pedophilia too.

Yet somehow it still manages to be better than most isekai. Depressing.
