Hi, I'm looking for shounen or sport mangas with little romance and no harem. I don't mind if it has a bit of romance, as long as it's not focused on that, and the romance won't disturb the overall plot. Stories with a clever MC with great scheming ability is a plus. Don't recommend any mainstream ones please (OP, Naruto, Gintama, OPM, haikyuu, KnB, Hajime no Ippo, etc etc), most likely I've read all of them. Thank you!
Shounen would be Kimetsu no Yaiba and The Promised Neverland Both are still new and I recommend Kimetsu but I don't know if Neverland is shounen since it is quite dark but still good. I don't know if they are already mainstream since no one is talking much about them
Most of what I would recommend has already been suggested but Full Drive is a newish shounen sports manga about table tennis. It's okay so I would ask to check that out. I'm a big fan of Kimetsu no Yaiba it's one of my new favourite series and I love how it doesn't follow the usual shounen formulas although the recent chapters have been a bit too close to that.
does Akagi count? it's mahjong. really tense. there's Umisho, but I don't know if it's harem. it's been so long since I read it. swimming. also, Takkoku. comedy table tennis. EDIT: ah, both umisho and takkoku have a lot of romance. I totally forgot.
Oh, is it seinen? I love seinen mangas too. And I haven't heard of those two, I'll be checking them out, thank you!
