Nakahara 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, he is also very proud of his reputation as the strongest martial artist of the Port Mafia, a young man of short stature, but despite his visual thinness, his physique is quite muscular. He has gray-blue eyes, bright red hair parted on the right side and shoulder-length. He loves his partner very much.
