Benitsubaki is a Japanese male antagonist with black hair and black eyes. He rapidly seized control of the Bonsai Clan's city through ruthless self-interest. His clan fuels its wealth via illicit activities, including gambling fraud and merciless extortion of protection money from local shopkeepers.

He brooks no failure among his subordinates, enforcing immediate and severe consequences for even minor mistakes, reflecting leadership devoid of fairness or composure. The sole exception is his bodyguard, Miyashita, toward whom Benitsubaki shows respect and grants unique latitude, suggesting a pragmatic recognition of value or loyalty not extended to others. Benitsubaki's methods of control and exploitation cement his position as a figure of corruption within the city's power structure.
