Kojiro Ryuuzaki is the president of B-Dash, the talent agency that represents the popular actor Ryouma Ichijou. He has reportedly worked alongside his secretary Tenma Hidaka for a long time and is known to look younger than his actual age. Kojiro possesses a strict and short-tempered personality, frequently raising his voice when angered and sometimes standing on his desk during arguments. He can be contradictory in his own reasoning, but he is fundamentally dedicated to his work and wants the best for his company. His primary motivation is the success and reputation of his agency; when he suspects Ryouma is involved with Izumi Sena, who belongs to the rival agency SenaPro, he becomes furious because of the potential conflict of interest. In the story, Kojiro acts as a supporting character and an authority figure who creates obstacles for the main couple, often representing professional boundaries that clash with Ryouma's personal feelings. His key relationships include his professional bond with Ryouma and his long-standing professional and possibly personal connection with his secretary Hidaka. He does not undergo significant development over the course of the series, remaining a mostly static figure whose role is largely comedic and antagonistic toward the romance between Ryouma and Izumi. Kojiro's notable ability is his effectiveness as a manager and president of B-Dash, though his volatile temper sometimes undermines his authority. Physically, he is characterized by his blonde hair, red eyes, and a ponytail, and stands at 178 cm.
