Ryūrō Hirotsu

Ryūrō Hirotsu (広津 柳浪,) is a member of the Port Mafia and commander of the Black Lizard.

Appearance
Hirotsu is an elderly man with grey, swept-back hair,a moustache, and a short beard ending in a spike. His eyes are violet, with a monocle over his right eye, secured by a gold chain.

He dons a long, black coat over a white dress shirt with a black bow - his pants and shoes being the same color. Over the coat, he wears a dirt-brown scarf that's nearly the same length as his coat.

A chain smoker, Hirotsu always has cigars on his person.

Personality
A veteran mafioso, Hirotsu maintains a stoic, calm demeanour, often speaking with a certain degree of respect and formality towards even his opponents and targets. However, Hirotsu's brutality, beguiled by his composure, hasn't waned despite his age.

Befitting of the Port Mafia's higher ranks, Hirotsu's a ruthless and dangerous individual, and won't hesitate to kill in order to further their gains. Furthermore, he isn't above mocking others before killing them, sometimes with a smile. His experience in the Port Mafia leaves him particularly seasoned in its expectations of him and others, and as such expects diligence and promptness out of his subordinates. Otherwise, he has no qualms threatening their lives to keep them in line, especially when it comes to Gin Akutagawa and Michizō Tachihara's quarrels.

Hirotsu's nonchalance towards the Port Mafia's violent ways goes as far as his smoking habits, as he claims a cigar always tastes best after "a job well done".

That said, Hirotsu takes his role and duty to the Port Mafia seriously. He values loyalty and ambition, specifically in Higuchi's case, when she insisted to save Ryunosuke Akutagawa from a rival organisation. Although initially ridiculing her impulsive behaviour, he respected her initiative and sense of duty, thus partaking in the rescue mission alongside Gin and Tachihara.

He later confronts Ōgai Mori about the conspiracy behind the former Boss' death. Despite Mori's defensive response, Hirotsu confides in Mori that the predecessor's murder was for the best, otherwise he would've turned Yokohama into a blood bath, dragging Port Mafia down with it.

Ability
His ability, Falling Camellia (落椿,), causes things that he touches to fly back with immense force.

It has been shown that his ability is powerful enough to stop and bend steel pipes with just a touch. When used on a human body, besides launching it, it can even cause the bones to break.

Background
It is revealed that he worked with the Port Mafia for a very long time before, even during the time when the former leader got murdered by Ougai Mori. Mori became the Port Mafia boss as of that incident in Chapter 30.

Plot
He appears inside of a certain warehouse by the Port, standing by the wall, smoking while waiting for his subordinates. When his subordinates arrive, they approach the warehouse door but Hirotsu orders them to back off. He then destroys the door with his ability, busting the door open with force. He enters a storage room filled with workers carrying unknown, heavy loads. Hirotsu interupts them, saying he is there to investigate regarding to the stolen goods from the Port Mafia in order to sell it to a black market. Based on evidence, the warehouse holds the stolen goods. As the situation goes on, one of the workers grabs a steel pipe to attempt to kill Hirotsu. Hirotsu stops the steel pipe with Falling Camelia and taunts the worker, who had witnessed the use of abilities for the first time. Hirotsu uses his power to demolish the man. Afterwards, he concludes this is the place and ordered his subordinates to kill them all. He then comments that cigarettes taste exceptionally good after a "job well done" and soon, the place explodes.

Later on, it is revealed Hirotsu is aware of Mori gaining his position through his murder, telling the boss that Dazai would understand the motive behind it.
