Schwarz Rose has seized copyrights to "Pride" and registered it as Louis Kisaragi's song for the Prism King Cup, rendering Hiro Hayami unable to use it unless Edel Rose pays ¥10 billion. Kazuki Nishina appoints Taiga Kougami as his successor while he trains with Rei Kurokawa. Edel Rose later discovers that Koji Mihama is composing music for Schwarz Rose's newest talent, Joji Takadanobaba. Hiro goes to the United States to confront him, while Kazuki trains under Rei's guidance. Edel Rose's janitor Ryo Yamada, a former Prism Star whose career was crushed by Jin through scandal, trains the rest of the Edel Rose students for the Prism King Cup.
