First of i already check in the search engine for No romance in Shounen but it seams that Shounen with romance is asked a lot. What i'm looking for is shounen manga that has no romance not even a hint. For example Prince of Tennis. XD
I'm pretty much hopping for something where there's hardly any female charecter's and when there is there hardly come out just a few times. A story with mostly guys and hardly any female's.

I hope some people Help me XD

vagabond is just him and the sword, he doesn't care much about the girl... i think! long time ago i read this one!

Let's see...
Shounen+no romance

There are lots of them, but from those list, I recommend:
Necromancer
Hareluya II Boy
Kenji: martial arts manga, lots of action. It's good despite quite old
Majin Tantei Nougami Neuro: his partner is female, but no romance whatsoever
Shiki
Magi
Tegami Bachi
Sakigake!! Cromartie Koukou: gag, you should read it if you like absurd things, and good laughs. Bunch of male casts, almost no female
Yumekui Kenbun

Edit 2:
Crows and Worst: both about delinquents
Durarara!!

As much as I can remember, there is no romance in Ares, nor in the classic (just in case) Hunter x Hunter.
Those are about fighting. About sport there is Hikaru no Go. No romance in here.

And, all three are awesome. 😃

Edit: I second Sakigake!! Cromartie Koukou, it's comedy, with no romance, and it's pure win.

I got Confused, I meant i checked the Forums for a similar topic but i couldn't find one. I never checked the Search Engine... I should really Pay attention more often when i write

Shounen Manhwa with no romance is also Noblesse

I highly recomend it 🙂

Law of Ueki is typical random-action-protect-your-friends and willpower-makes-you strong shounen, but I think it has a unique charm to it. No romance.

Eyeshield 21 has like, practically none. Maybe once or twice it's stated that so-and-so is that person's girlfriend, but definitely not a focus.

Monster Soul doesn't really have any either. Short and a little goofy, but fun.

Another sports one, Whistle!. For some reason this remains one of my favorite soccer-themed mangas ever, perhaps because of the character development that takes place alongside the intense competitions.

Most of these have female characters, but they're either not a big part or definitely not romance interests.

One piece. There's jokes about Sanji getting nosebleeds over Nami and Robin, as well as Hancock wanting to marry Luffy, but those are just comedy relief.

Black Cat

Bleach?

Gintama There's no romance in there... It's all just pure comedy and great arcs... Well there is one arc about a girl and one of the main characters and their relationship but it ends quickly due to her death. Well that's it, just girls chasing after the lead Gintoki but he doesn't give two sh*ts about them.

Hunter x Hunter is all about bros & life goals.

One-Punch Man is all about jokes & beating the crap out of things.

Jojo's Bizarre Adventures parts 2, 3, 4, & 5. Not even sure if you could call what little part 1 had romantic.

Noblesse. The author teases a few, but they are all squashed.

GetBackers teased one romance but destroyed it in its second season.

Tiger & Bunny supposedly has none, but the manga was dropped by the scanlators when the anime ended.

Slayers. A potential romance was dropped after part one & never brought up after that.

Prince of Tennis, but you really need to like tennis.

Yugioh. Yuugi kinda has a love interest at first, but they become just-friends.

Gintama is too mean spirited to give its characters any serious romance. The MC actively avoids getting a GF.

Devilman. The MC decides he loved his best lady friend after she left the series. He sure never showed it.

I liked Gamaran a lot. Give it a shot!
