Description
The Producer is the adult in charge of the Third Entertainment Division at an unnamed talent production agency. He is a newly promoted producer who is assigned to manage this unconventional unit, which consists entirely of elementary school-aged idols who are all under 149 centimeters tall. Because more experienced producers are reluctant to take on such an unusual group, the position falls to him, and he accepts the challenge despite having no prior experience with child idols.

In appearance, the Producer is a short, young-looking man with brown hair and eyes. He is an adult, but his small stature and youthful face mean he is frequently mistaken for a child, something he is self-conscious about. He has an older sister, and his official profile describes him as someone filled with dreams and passion. Despite his initial preference for producing more mature idols, he takes his responsibilities seriously and dedicates himself fully to the girls placed under his care.

His motivations center on a genuine love for idols and a desire to see them shine. He dreams of leading the performers he produces to the stage of their dreams, and he promises his new charges that he will create a stage unlike anything anyone has seen before. This sincere passion is what convinces the girls to trust him. Early on, he admits he had imagined working with older idols, but as he observes the talent, effort, and earnestness of the young members of the Third Entertainment Division, he changes his outlook and decides to support them wholeheartedly.

In the story, the Producer serves as the central adult figure who guides the group through rehearsals, promotional photo shoots, meetings with the agency, and the process of preparing for their debut. He arranges work opportunities, accompanies the girls to events, and handles the professional side of the idol industry while making sure the children feel safe and supported. Notably, he addresses all the idols by their last names rather than treating them as little children, demonstrating that he respects them as working professionals. His approach to the girls is patient and attentive; he listens to their individual worries and finds ways to address them, whether it is reassuring Nina Ichihara that her personality, not her animal costume, is what draws people to her, or working to earn the trust of Arisu Tachibana, who initially doubts his abilities. The two bond over their shared fascination with idols, and that connection becomes the foundation of the group's confidence in him.

His key relationships are with the nine girls of the Third Entertainment Division, and each interaction reveals a different side of his supportive nature. With Arisu, he proves his seriousness and earns her respect through his dedication. With Nina, he offers emotional reassurance and a promise that her father will be able to hear her perform no matter where in the world he is. He also maintains professional relationships with his seniors at the agency, including a supervisor who helps him navigate his duties, and he works alongside his idols during a filming production, deepening the mutual understanding between them.

Over the course of the series, the Producer develops from a rookie who is unsure how to handle such a young group into a dependable manager who understands each girl's strengths and struggles. His own insecurities about being mistaken for a child fade into the background as he focuses on the growth of his idols, and the trust between him and the girls strengthens with every shared experience. His notable abilities lie less in any special talent and more in his perceptiveness, his capacity to remain calm and encouraging under pressure, and his talent for arranging the practical details of idol work so that the girls can give their best performances. Through his determination and care, he becomes the steady presence that allows the young idols to move toward the stage of their dreams.
