I'm looking for manga may be 10 years ago 5s4tu

The protagonist is a boy aged around 14 years old.
The story occurs may be around desert

apart from that boy there are 2 women who are older than him stay by his side.

One has big breast and stupid
another one is flat but clever.

The word that boy always said is something like
"Still I am looked like this, I was born to see the world for 14 years already"

may be the boy uses gun as a weapon <-- I'm not sure.

Can anyone answer me?

Thanks

Your post is not exactly easy to understand. Guess english isn't your first language (nor mine btw).
Anyway I think maybe it could be Kazan

Yes, sorry for my English. and thank for your effort.

But it isn't Kazan

Sunabozu?

I'm not sure...but maybe what you're looking for is 'Maoyuu Maou Yuusha'
If it's not that, then I think you should check these ones:
'Desert Coral'
'Shoukoku no Altair'

Also, sorry, but could you please tell me how to put the url (link) thingy?
Cuz' I have no idea. : 😔

I haven't read it so I can't really tell, but from what you're saying (and a slight amount of research) I feel you're talking about Soul Eater.
