Starmaker Production=

The agency founded by Yumenosaki alumnus Eichi Tenshouin. Its name is abbreviated as StarPro. While he's created a system that automatically enrolls all students of the Yumenosaki idol department into an appropriate ES agency upon their entry in the school's idol course, there are many students who willingly choose to affiliate with StarPro, which has an atmosphere familiar to Yumenosaki students. StarPro's motto is "Creating joy for both idols and fans."

Cosmic Production=

An entertainment agency that runs Reimei Academy and Shuuetsu Academy, which both cultivate young, talented individuals. Its name is abbreviated as CosPro. It manages the schools by nurturing idol students in Reimei Academy and then transferring the highest-quality students to Shuuetsu to shelter them there. Though it has steadily risen in social standing in the entertainment world due to their methods, the SS has caused their status to somewhat plateau. Their agency motto is "Providing only the highest grade entertainment."
