Tomohiro is a man who works as one of the managers in Sweetfish Productions. He is the first manager that all of the idols have had in the past and when the story begins he is currently managing the third batch of idols.
President Mariko (), (Seiyū - Chinomi Takema)
Mariko is the president of Sweetfish Productions, which is the company that all of the Lovely Idols are affiliated with. She was the sole reason why the third batch had a delay on their debut until Tomohiro could figure out what they were lacking. She tends to have a serious, businesslike personality who only wants the best from her employees.
Miki Fujisawa (藤沢 美樹, Fujisawa Miki), (Seiyū - Eriko Kawasaki)
Tomohiro's and Ruri's older sister who is also a manager. It was because of her Tomohiro got his job as a manager.
