City Hunter vol.1
It was pretty good. Ryo Saeba is badass, he gives no shit about anything.
The art is already pretty good, even for a 80s manga. I was surprised to see that it was quite violent, and there's nudity! You even see a naked chick getting shot :lol
It transitions into more of a comedy, which it does very very well, but does get serious again. Honestly City Hunter is my favorite manga. It's just so good.
