During the run, the amount of times Golgo smiles is 0. He does not smile. This is a serious anime. So. Damn. Serious. No matter how ridiculously awesome and amusing the events get, there is absolutely no room for character centric comedy. He also has sex with something like 34 different women during the run, and no matter how much he likes these women, he never shows it in any other way than sex. He never speaks, he never answers their feelings nor shows an expression of any sort, and in case they happen to witness him practicing his profession, there is no soft spot in his hard. Any witness dies. There is no limit to how Man and how loyal to himself this dude is. If there ever was a person who doesn't break his character, it is him.
