Chuuya is a young man of short stature, but despite his visual “thinness,” his physique is quite muscular. He has large, blue-gray eyes, shoulder-length bright red hair parted on the right side, and a wide smile. The oblique bangs visually cover mostly the right side of the face. He ties his hair back into a ponytail and combs it to the left side. Nakahara's most striking accessory is his black hat with a red ribbon wrapped around it and a thin, silver chain that hangs over the brim. He is wearing a white, white dress shirt with a high, stand-up collar. He never buttons his shirt co Chuuya is a member of the Port Mafia Executive Committee and Dazai's former partner. Has the ability "Vague Sadness". At first glance, Chuuya seems to be a temperamental, rather arrogant, and sometimes rude person. He enjoys fighting and is happy to have the opportunity to demonstrate his fighting abilities, and is also very proud of his reputation as the Port Mafia's strongest martial artist. The mocking remarks are coupled with his pride, as he is not afraid to ridicule his opponents mid-fight. As befits a member of the Executive Committee, he does not hesitate to eliminate the enemies of the Port Mafia by any means necessary, including murder. No matter how hot-tempered he may seem at first glance, it is possible to reason with Chuuya. He's actually quite reasonable when no one is pissing him off. While his skills signal an inherent threat that is an integral part of his character, he is quite reliable. As ruthless as he is, Chuuya rarely disregards people's lives and understands the importance of compromise and rationality. He refrains from overly violent methods when necessary, and also has enough common sense to understand when enough is enough and he needs to stop. Chuuya Nakahara's ability is based on manipulating gravity. While dating, Dazai and Chuuya often remind each other of how much they hate each other, but Chuuya trusts Dazai enough to activate "Corruption", which can only be undone by Dazai's ability.
