Chuuya Nakahara

On the surface, Chuuya is a calm yet rather arrogant man. He revels in fighting, happy to show off his combative ability, and taking great pride in his reputation as the mafia's strongest martial artist. Taunting remarks pair with his pride, as he isn't above ridiculing his opponents in the middle of a fight. Befitting of an Executive, he has no qualms eliminating the Port Mafia's enemies by any means necessary, including murder, however, isn't nearly as homicidal in his tactics as members such as Ryuunosuke Akutagawa and the members of Black Lizard tend to be. Chūya is quite short with a petite, yet muscular build. He has blue eyes, and striking orange hair that frames his face, with a longer section that falls just past his left shoulder. He wears a black hat with a brown hatband and a thin silver chain that hangs over the brim.

His outfit consists of a white button-up shirt under a grey vest, a black choker, a black ribbon bolo tie held together with a small silver buckle, an open black cropped jacket with the sleeves rolled up at the elbows, black slacks, a black belt hanging off his right hip and black low-arch shoes. He is almost always seen wearing black gloves. Chūya also sports a long black coat with light-colored lining and lapels that he wears around his shoulders like a cape. The undercoat is a light shade of red.

In order to give himself a sense of restraint, he preferred kicking largely over throwing fists, never even removing his gloves. He figured if he came to a fight where he had to remove his gloves, it was because he could no longer enjoy the rush of a battle, and genuinely needed to defend himself - in other words feeling an attachment to the life he lived, even if he felt like a foreign soul in a shell, rather than a human being. This holds true to the present, as Chūya's only seen removing his gloves when using Corruption in dire moments.

After Rimbaud elaborated his own beliefs on humanity, Chūya had a bit of a change of heart, taking his own life a bit more seriously. The Sheep's betrayal affected him greatly, alongside Port Mafia's direct involvement in uncovering the truth of his origins, but ultimately led to his loyalty in them. The drive for learning more about himself contributed largely to his rise in rank, much faster than anticipated.

Chūya's ultimate downfall is his intense disdain and hatred for Dazai. The two never got along, with Chūya instantly hating Dazai's underhanded, warped strategic personality. Dazai has always gone out of his way to dehumanize and ridicule Chūya, constantly attacking his pride and even driving Sheep to abandon and betray him in the past. Even now, the slightest insult from Dazai will set Chūya off on a tangent, taking full advantage of his quick temper and pride. This makes it easy to distract Chūya from tasks at hand. Nonetheless, as part of Twin Dark's nature, Chūya acknowledges Dazai's role as the tactician, extending minimal trust in at least knowing that Dazai knows how to effectively overcome a situation. He is a five foot three tall man. He was born on April 29 and is 22 years old. He is a trans man and still has female genitalia.
