ARP (nominally an abbreviation for Artists Republic Production) is a dance vocal group which holds live performances — featuring singing, dancing, and interactive talking with the audience — in real-time using the latest augmented-reality technology. The ikemen (handsome) group members include their de facto leader Shinji, the talented dancer León, and the members of the Rebel Cross duo (designer Daiya and composer/writer Rage).
