Title is misleading. Give it a read anyway.
A title like
"After subjugating the Demon Lord, the Legendary Assassin plans to live an ordinary life as a Guild Member."
would be better.
Do note that I've got like a hundred better titles, but I'm keeping to the whole "Explaining the entire manga is a single sentence" structure, cuz lots of mangas tend to do that for their titles.
i wanna have more y is this so slow some rdm copy stuff gets 1 in a week and this 1 in 4 months y is it always like that
i just read that this once had the smut tag like wtf i mean yes but noo thats not smut
i started rereading it and in the first chapter he was like
ism gonna use everything to killher but stabs her in the head with a tiny ass dagger and somehow she doesn't die
i mean its smoll but it should be enough for that
Harem tag is there because of one-night stands, mostly. No idea why the author decides to include them though, there's a decent enough plot without them and Roland doesn't give off that vibe.
He does create an actual harem with a vampire later on, except I think the author forgot about her because she's not in any of the recent chapters
