Crying Freeman

Great manga about assassin working for the Chinese mafia, who shed tears after every killing because of his regret that once he was ordinary man, before witnessing murder and brainwashed into becoming assassin. On one of his job girl painter draws his face, so he must kill her, but instead fall in love with her and invites her into organization. After that organization is challenged by other groups, and every time they send some monster to defeat crying freeman, but every time they fail. After each killing and mobster tripping there are huge amounts of fucking, and art is really beautiful maybe because it's not full fledged with those huge eyes and shit, and in some sense it's both menacing story and sad at the same time.
