An agency manager dreams of seeing shooting stars land on a stage. To make it happen, she has been given four new idols to develop into a group: MARGINAL #4. Kirihara Atom is talented and difficult to manage. Aiba Rui looks gentle and leaves a cold impression. Twins Nomura L and R are mirror images with opposite energy—L is showy and self-assured, R is quiet where his younger brother is loud. Their seniors, the duo LAGRANGE POINT (Mikishima Shy and Himuro Kira), carry their own ambitions and their own complications. Protagonist Kataoka Yue is the manager tasked with turning all of this into something that shines.
