I really liked Grimgar and wish it would get more seasons someday. It’s in a sort of Isekai fantasy setting, but the way they go about making every part of that situation seem realistic and horrible is great. From having no food or money to how horrible it actually is to have to stab something to death felt like a really fresh take on the genre at the time. Just be warned that you’ll have to pick up the light novels to continue the story. It’s no berserk '97 cliff hanger, but you definitely want to know what’s up with the world and why they’re even there which isn’t covered in the anime.

Also, on topic, berserk '97.

Why is it so good.

I’m going to second this. The fights are still pretty action packed + there’s a derpy looking flying turtle.

That was censored in some regions, so not everyone will know the reference.
