One of my favorite LN series is Danmachi or " Is it wrong to try to pick up girls in a dungeon ? " and one im currently reading and enjoying is "The Empty box of Zeroth Maria" I would say check those out .
I've already watched the anime and I absolutely LOVED it so I started reading the Light Novel, Chapter 1 and I have to say, it's awesome. Thanks for the recommendation. Will definitely be reading that! :)
