The first one is common enough that I could name one. I think the mothgirl could count as the events happened exactly like how he described it. There might be a human version but I forgot if it existed.
Looks like his main skills are meant to be for a ntr scumbag and not really for anything good. I think its possible he also summoned by the same being as that bitch girl.
This story turns into the usual Evil God usurped the Good God like many of the 2010-15s isekai stories. I actually like this manga as it minimizes all of the boring monologue to actually show the story.
Might also be why the story is somewhat in hiatus as the web novel is in hiatus for 3 years...
You forgot the whole phrase. Its Zamaa Miro which rougky translates to Serves You Right. Its actually closer to getting karma for the antagonist's bad attitude or evil personality.
There they go again with the hint that the MC is more special then he seems to be. Hopefully the thief guy would just become a recurring companion rather than a permanent one.
The new lewd girl looks like a mob character that I dont doubt her that she die. It would be a Lynn move though if she out of all the people actually survive later on.
Remember that the demon lord said her subordinates either died or left
her so I doubt the one who stole it is a demon or monster. Its more likely one of the humans or humaniods.
