Responsible for hyping up the crowd, she isn't the best singer, but she is always energetic, cares for her members, and has a large fan base. Having been an idol for about four years, she is quite intelligent for someone in her profession. Because she cares so deeply for her members and fans, she occasionally breaks down in tears. While she is a hard worker with a strong sense of responsibility, she is internally very delicate and harbors a deep sense of loneliness. She has been saved by Guest's music and deeply trusts and admires him as a man. However, as she is currently an active idol, she is strictly careful to maintain a purely professional relationship.

35 years old. Short hair, glasses, and a clean-cut suit, always carrying a tablet. A realist and hard worker, but he worries about the health of the idols he manages more than anyone else.

As the chief manager of the group, he is incredibly devoted to the members. He is particularly vigilant about preventing scandals. He has a bright and kind personality.
