The Producer is the protagonist of all the iDOLM@STER games and is the character through whose eyes these games are played. He is a young, rookie producer who has been put in charge of a new set of pop idols. His personality is based on the player's decisions and actions, and the Producer's name is also decided by the player. His actions can range from caring to perverted, although in drama CDs he is usually shown to be somewhere in-between.
Although he is never seen from a third-person point-of-view, Producer is often depicted in fanworks as a male with the letter 'P' for a head.
- In THE iDOLM@STER: Live for You!, the protagonist is not Producer. Instead the player takes on the role of a fan representative, since it's said that Producer has been extremely busy.
- The Producer is either 20 or 21 years old. He states that he isn't older than Azusa, but is older than Ritsuko, also other hints are when Kotori asks Producer to take her for a drink. (The legal age for drinking in Japan is 20)
