Newly launched idol ensemble Marginal#4 aspires to send their affection across the farthest reaches of space. The group features Atom Kirihara, Rui Aiba, and twin brothers L and R Nomura, all determined to climb the pinnacle of idol fame, echoing Pythagoras Productions' earlier act Lagrange Point. Their goal is to send kisses across the galaxy. Outside the stage, Marginal#4 members lead typical lives. From claiming a clubroom and hunting lost underwear to shooting TV spots, their schedules brim with mischief. They rehearse tirelessly, host meet events, maintain an online presence and connect with their audience. Amid this whirlwind of activities, they chase stardom and aim to win over their supporters, the Starclusters.
