Action/Fantasy recommendations please

Hi, I recently got back to reading because roblox got boring again.

I prefer if there was no harem because most of the girls in the harem are useless af. It's either gonna be one of those damsels in distress or those people who cling to the main character and i find them annoying (sorry not sorry). And some of them focused on the fan service that the actual plot is gone.

I don't mind romance on the story but I wish it would be something like Dungeons & Artifacts where the female lead is actually good and fl had a good chemistry with the ml. Another example would be The SSS Class Suicide Hunter, although the romance felt like it was rushed, I really loved the connection Ravel and Mc had.

And I would actually like a story where BOTH MC AND FL would destroy the world together, a badass couple and both of them are reasonably powerful? (if that makes sense).

sorry if i'm picky TT
