Personality
Chuya is hot-headed, and can't stand out even a minute with Dazai by his side as both of them will always taunt each other to no end. He obviously knows Dazai very well believing that he (Dazai) will not trick him. Nakahara hates Dazai for betraying the mafia and joined Armed Detective Company. He is also very sharp at analyzing his battle against Dazai when he noticed that Osamu has blocked every attack he lands at his former partner. He is kind of gullible when Osamu is to put him in a dilemma as shown in chapter 10.

Ability
His ability, For The Tainted Sorrow (汚れつちまつた悲しみに,), revolves around gravity-manipulation, allowing him to manipulate and alter the gravity of anything he touches, keeping it that way until a certain period of time.
 * Corruption is the true form of Chuya's ability and is exceedingly dangerous. It is activated by chanting ' Oh, Grantors of Dark Disgrace. Do Not Wake Me Again '. This ability allows him to manipulate the gravitons in his surroundings. By increasing his own density, he is capable of crushing a tank with his bare hands. He is also able to shoot balls of compressed gravity that act as black holes that swallow anything. Without Dazai to cancel Corruption, his power will rage on until he dies.

Background
It is shown in chapter 31 that Chuya is taken by Ozaki, so it is possible he was raised by the latter during his childhood.

it is unknown what his past is or how he is raised by the mafia. We don't know what kind of relationship he had with Osamu's time in the mafia in the past.

He and Dazai used to be partners during the later's days in the Mafia, and together were known as soukoku (double black).

Plot
He first appeared where Osamu Dazai is held with shackles around his arm, with two chains hanging separately up in the air. Feeling something is off, he questioned what the latter has in his head, in which he received that Dazai is awaiting for his punishment. His anger is triggered with this, Chuuya claimed that with this attitude, he could have killed Dazai since long ago.

Known as the strongest martial artist in the Mafia, he broke Dazai's shackles with one swing of his kick, even causing the wall behind the prisoner to crack. He then challenged Dazai into a duel, and to his amusement, Dazai already broke the shackles before Chuuya's arrival, which only excited the mafia.

After sometime, Dazai finally told Chuuya about his intention that he did all these for Atsushi's sake. A five boss meeting of the Mafia will soon be held due to Dazai's letter that stated 'If Dazai Osamu is dead, all the mafia's dark secrets will be exposed'. Dazai further explained that using Chuuya who came to kill him, he would force Chuuya to be viewed as a traitor by the Port Mafia, and therefore, Chuuya have no choice but to run away and saves Atsushi from Akutagawa.

Chuuya cancelled his plans to kill Dazai, choosing to retreat. As what Dazai had predicted before the duel, Chuuya told him where Akutagawa keeps the records of Atsushi's bounty.
