I have never seen this anime before. I've HEARD it's title is possibly something stupid like "Golgo 13" or the like.
Correct me if I'm wrong, because if it's truly Hitman the animu I wanna' fucking see it. I posted a complaint on /a/ a while back about wanting to see an anime about a hitman who does all the shit 47 does like disguises and accident-faking, and the fact there are none.
tl;dr, OP better not be shitting me.
