Omg of course, there are lots of them but here are some of my favorites:
-Jojo's Bizarre Adventure. The main character of part 6 is even female! Jojo's has amazing fight scenes and is basically queer culture. I'd guess that at least 60-70% is pure action
-Haikyuu!! Very cute, realistic, funny and wholesome with some emotional scenes in them.
-Attack on Titan. It's very tragic and raw. Only the very first chapters are shounen, the rest is seinen.
-Hunter x Hunter. It is very well-written and isn't scared to sometimes not follow the conventional shounen pattern.
-Demon Slayer. It's also a tragedy, though most of the times it's bittersweet. The visual metaphors used during fight scenes are amazing!
-Claymore. The main character and the majority of the other characters are female, there's no romance but a slight homoerotic subtext if you'd ask me
-Dorohedoro. It's very recent, but it's so well-written and cool ugh. Slipknot meets mushrooms and magic
-Mob Psycho 100. The majority of the characters are either 14-year olds or ghosts or a sweaty sexy con man in his midlife crisis so you don't need to worry about harem stuff. It also doesn't have any romance in it, I recommend this a lot.
I hope this helps!
Can some one recommend me some Manhwa/Manga with just action, no harem or romance (๑•ㅂ•)و✧
