Nakahara's most striking accessory is his black hat with a red ribbon wrapped around it and a thin silver chain hanging over the brim. He wears a white dress shirt with a high, stand-up collar. He never fastens the collar all the way. Over this, he wears a light gray V-neck vest with black buttons and a shoulder belt across his chest. He also wears a black bolo tie with a diamond-shaped buckle. Over the vest, he wears an open, cropped black jacket with the sleeves rolled up to the elbows. He wears loose-fitting black trousers. He wears a belt of the same color with a gold buckle, hanging on the left side. He wears black low-heeled shoes with a pointed toe. Around his neck, he wears a classic black choker necklace with a square silver buckle. He is almost always seen wearing black gloves. Chuuya also wears a long black coat with a light red lining and lapels, which he wears over his shoulders like a cape.

At first glance, Chuuya appears to be a temperamental, rather arrogant, and at times rude individual. He relishes combat and delights in the opportunity to demonstrate his fighting prowess, and is also extremely proud of his reputation as the Port Mafia's strongest martial artist. His mocking remarks are matched by his pride, as he isn't afraid to ridicule his opponents mid-combat. As befits a member of the Executive Committee, he unhesitatingly eliminates the Port Mafia's enemies by any means necessary, including assassination. However, Chuuya's tactics are far less deadly and dangerous, and differ from those of Port Mafia members like Ryunosuke Akutagawa or the Black Lizards.
