It's a very bad manga. This is a 18+ review for an 18+ manga, just so you all know. The best way to describe it is if you want to watch a blockbuster movie, but you get a porno instead. The characters are badly written, the most interesting part in the worldbuilding of a fantasy series, doesn't exist. This series has nothing good going for it. Their are only 2 things that you might enjoy about it; 1. It isn't an isekai or reincarnation story. Just a guy in a fantasy world. So that is something. 2. It's basically bad porn. Not a whole lot of sex scenes,lot's of dialoge that isn't intersting at all. Barely any action, and if the rare occasion happpens, it isn't that great. But it has uncensored drawings of naked elves & half-elves, so if that is your thing, you might enjoy it.
