kuroi takao
The president of 961 Production, as well as its producer. Like the other producers, he's not seen, but like the 876 Pro producer, is seen as a silhouette. After his original idols join with 765 Pro in The Idolmaster 2, he forms a new idol group called "Jupiter", formed by male idols. He is depicted as a cruel and ruthless businessman who will do anything, legal or not, to sell his idols and get ahead of 765 Pro and tell lies about them to his idols. He tends to treat his idols more like tools choosing the most appealing and talented rather than building their abilities, the complete opposite of Junjirō's methods.
He and Junjirō were once old colleagues and friends, but later they had a falling out after Junjirō disagreed in the way Takao raised his idols. Since that incident, Takao has vowed to destroy Junjirō's company and his idols by any means necessary.
His company is actually named after him, as "961" is pronounced ku-ro-i in Japanese.
