The story takes place in a record company called Gandhara Music. Sumire Tsubasa (voiced by Hisako Kanemoto) is a new agent at the company. However, she was immediately informed that she would be responsible for three idol groups at the same time. She had to bear such a difficult task right from the start. Sumire Tsubasa doubted whether she was deceived. Kitamon Rumbisa (voiced by Daisuke Ono), who always appears as a prince but actually lacks common sense in life, Kuni Tatsumochi (voiced by Daisuke Kishio), who is petite and black-bellied, Kaneshiro Tsuyoshi (voiced by Toyonaga Toshiyuki), who is serious and even a little old-fashioned, Ashu Yuta (voiced by Natsuki Hanae), who is innocent, romantic, very friendly and enthusiastic, and Kenju Aizen (voiced by Kato Kazuki), who is often immersed in his own world. Sumire Tsubasa has to deal with these handsome but troublesome guys.
