Marginal#4, a newly formed idol group consisting of Atom Kirihara, Rui Aiba, and twin brothers L and R Nomura, aspire to extend their kisses to the farthest end of the galaxy. Their ultimate goal is to climb to the top of the idol world, much like their predecessors, Lagrange Point, from Pythagoras Productions. Although these boys lead ordinary lives as high school students when they are not performing, they find themselves frequently caught up in a world of mischief. Their days are filled with anything from securing a club room to tracking down lost undergarments, or even shooting commercials. Despite these challenges, they continue to pursue their dreams of becoming shooting star sensations and winning the hearts of their fans, known as the Starclusters.
