Best fighting anime *not the super popular ones*

obviously rn the answer most ppl would give would be jjk or demon slayer or maybe any of the naruto/one piece/bleach types (ive seen all these) but i'm looking for something lowkey with amazing fights. Personally i loved solo leveling, 7ds, tower of god, mashle,kaiju 8 and black clover which i know aren't low key some low key fighting anime i thought were great and am looking for more of are blood blockade battlefront, mononogatari (malevolent spirits)

any help is appreciated!!
