Anime similar to Solo Leveling

I’m trying to get my boyfriend more into anime but he’s very picky with what he likes. I tend to like more obscure stuff that he’s not into.

His favorite anime is Solo Leveling. He also likes Frieren, Kaiju No. 8, Akame ga Kill, and Black Clover. He watched like 1000 episodes of One Piece and he enjoyed parts of it.

Any suggestions for him? He doesn’t like childish art/chibi stuff, pervy tropes, and cheesy goofy stuff. He REALLY disliked Fairy Tail because of some of these things.

Thanks everyone!
