So much trouble could have been avoided in the prologue turning point if they brought a Theocracy priest over. You know, those people with a spell that can detect lies? That are in residence of pretty much every town/city with an adventurers guild? They are the ones that determine if a request was properly completed by a guild party, so it's not like grabbing one of them for a national level issue is hard..
Female lead strips down to her panties while some boys photograph her in one part of the story (All tents stay pitched and covered) and the male lead watches while growing more annoyed at her fetish (He bangs her hard as payback after). That's about the most NTR-like part of the story in my opinion. Anyone wanting to avoid that part should skip the mid 1/3rd (give or take) of the beauty pageant (Ch5).
