Black Lagoon
Rokuro "Rock" Okajima
A complete misfit in the crime world of the fictional city of Roanapur, where the worst of the worst come to gather: Hookers, assassins, bounty hunters, thieves, serial killers, crime bosses and any dangerous and/or illegal occupations. Rock isn't any of these. In fact, he wasn't dangerous at all. He was a simple business man... until he was kidnapped by the Lagoon Company. After being abandoned by his own company, he decided to join the delivery business of Black Lagoon (which may or may not come across the law at times). Contrary to most of the people around him, he's polite, calm, intelligent and prefers negotiations before violence. Not so badass, right? Right. But at some point, he was able to manipulate everyone (I haven't read this part yet, but I'm getting there.) according to his plan. No one knew they were being manipulated until it was too late. This instantly made him one of the most dangerous people in Roanapur, if not THE most dangerous. His colleagues can vouch for that.
