Ryunosuke Akutagawa

He is not afraid of pain and defeat, just to hear a word from a "certain person." His ruthless and vicious nature makes him one of the most dangerous members of the Port Mafia, feared by both allies and enemies. Much of the obedience from Black Lizard subordinates stems largely from fear of his short-tempered nature and general intolerance of incompetence.

A self-titled "Dog" of the Port Mafia, Akutagawa demonstrates a willingness to carry out cruel orders and assignments to achieve not only the goals of the Mafia, but also his own interests. Ruthless and harsh, Ryunosuke is unquestioningly ready to kill anyone, including innocent civilians or children. He is hostile towards the weak, but does not like senseless torture, preferring to kill immediately when possible.
