Chuuya Nakahara

Physical features: Bright orange hair, usually with a long strand that falls over the left shoulder, and intense blue eyes. Distinctive attire: Black wide-brimmed hat with ribbon (red or brown) and chain, long black coat worn over the shoulders, white shirt, dark red or gray waistcoat, bolo tie (black with silver buckle) and black gloves. Style: Considered "fashionista", he combines formal clothing with modern or combat touches, including black pants and dress shoes. Previous appearance: Previously, he wore a black leather jacket with padded shoulder pads over a sweatshirt, with a more "street" style.

Temperamental and Proud: He is prone to outbursts of anger, especially when provoked by Dazai, reflecting a possible "explosive disorder." His pride is a "mask of strength" stemming from his past in the group "Sheep." Loyal and Professional: Despite his explosive temper, he is a highly respected and loyal member of the Port Mafia. He takes his work seriously and looks after his subordinates. Strategy and Skill: As the mafia's best martial artist, he is strategic in battle, although he usually relies on his brute power, which is immense and destructive. Relationship with Dazai: He feels a deep disdain for Dazai due to past betrayals, but maintains absolute professional confidence in his tactical ability, forming the "Double Black" team. Internal Struggle: He questions his own humanity (being the container of the Arahabaki entity), which generates insecurities hidden beneath his tough facade.
