Ryusei

Ryusei is the top pop singer in the country. He is very successful and is also signed to Cosmopop. Kyouta idealized him before meeting him. Ryusei tends to be egotistic and seems jealous of Kyouta's emerging success, yet pushes him to do better (through his own methods and for unknown reasons). Ryusei is the biggest mystery, where do his alliances lie?
