Dressed in a reddish-purple jacket and slacks, a green vest, and a black shirt. Personality: Speaks with a Kansai accent. Usually cheerful and frank, never letting his smile fade. Even in harsh missions, he carries them out with joy, considering the results and fame gained upon success. His catchphrase is "I'm so happy." He deeply values and trusts Asakura, who has been with him through thick and thin since their early days, as his partner. He has a strong sense of camaraderie within the Tennoji-gumi. Past: Grew up in a complex single-parent household; his mother was gone before he could remember, and his father was a low-level yakuza associate. Living as a bottom-tier member who never received a formal cup, his father had no steady income, leading to a life of extreme poverty. Despite this, he loved his father dearly, and his father poured as much love into him as their poverty allowed. On days they had time, they would have modest luxuries at family restaurants, but they could never afford the most expensive item on the menu—the strawberry parfait. Thus, the strawberry parfait became a food with special sentimental value to him. However, one day his father was sent as a human bullet for the gang and never returned. Later, he met Asakura in high school and joined the Tennoji-gumi to inherit and realize his father's dream of "becoming a boss." Combat: A high-performance all-rounder wielding both a handgun and a dosu dagger. He possesses exceptional tenacity and willpower. His tactical eye for reading situations and his strategic thinking—accurately grasping the big picture to execute objectives without hesitation—are also highly superior. Other: Loves strawberry parfaits. Views Asakura as his special partner among his subordinates.

Acts as the straight man. Calls Kido "Kido-no-aniki." Always calm and collected with little emotional fluctuation. Past: Born into a family of prominent politicians. His father was a prefectural assembly member in the Osaka area. Consequently, he was forced into various educational and extracurricular activities by a family that valued the political dynasty's name. He had a natural talent for martial arts, defeating middle schoolers in karate while still in elementary school, but he fell short of his parents' expectations in academics. His perfectionist father gave him the cold shoulder, stating he "wouldn't accept anything less than 100 points." His mother and brother followed suit, showing him no affection. He stopped returning home upon entering high school. One day, while spending his freshman days fighting, he was challenged by Kido, a senior and the school's gang leader. Despite landing twice as many hits due to his karate experience, he was defeated by Kido's street-fighting prowess and, more importantly, a thick conviction that Asakura lacked. Curious, he questioned Kido and learned he grew up in a household that was the polar opposite of his own. He began to admire Kido, who spoke proudly of his father despite not being socially respectable, and started hanging out with him. One day, a formal notice of disownment arrived from his family, but Asakura didn't care as he had already given up on them. He intended to drop out of school, but Kido, who had already graduated and joined the Tennoji-gumi, provided financial support so he could finish. After graduating, Asakura joined the Tennoji-gumi and became Kido's right-hand man. Combat: Dual-wields a handgun and a dosu dagger, handling both with incredible speed.
