Shienas Bizarre Adventure Assassins Crusade part 3 . 100/10 would watch
Looks like part 5 to me, or later. Eyes and lips, especially.
Stone Ocean was the first thing that came to mind for me
It's definitely got the simpler, skinnier Part 6/7 artstyle, but the title is clearly indicative of Part 7. Steel Ball Run = Titanium Bone Les, a metal followed by a 4 letter word starting with B followed by a three letter word. Also the title looks very similar: http://vignette2.wikia.nocookie.net/jjba/images/9/92/Volume_84.jpg/revision/latest?cb=20120215021202
And yes, I did make an account just to say this. That is all.
