Assassin

[Samcyxk]

I was wondering if anyone knew an anime based around/prominently features an assassin - best if they pose/have a day job as a businessman.

BESIDES Sven from Black Cat. I'm not sure I want use him even as a last resort.

Canaan from Canaan and all the characters in Gunslinger Girl. Oh and, if you decide too use gunslinger girl, I'd recommend checking out episode 7 from the first season. Funimation has it legally uploaded on youtube here: http://www.youtube.com/watch?v=kHahtHjym3E Jean and Rico seem like they fit what you are looking for.

Phantom ~requiem for the phantom~
Gungrave (maybe)
Golgo 13
Black Lagoon [in the second half of the first season]. Ok, so that one's more of a mercenary...but it could work
Noir

and that's all that's coming to mind atm

Darker Than Black should do. And maybe Cobra could work, too (not sure).

You need something, how can I say it....realistic ? Or something like ninjas / samurais etc...can fit ?

Yeah. I mean, ninjas/samurais as a last resort, but with the idea I have running through my head, I really want a businessman/assassin.

There's Nabari no Ou.

They're modern Ninjas, some of them have their own businesses and stuff and wear suits.
