The manga centers on Hira, a lazy manager who is ordered by his company to be the producer for COPPE, the company's rookie idol group full of trouble-making girls. While all the girls make his life harder, he spots a girl one night and scouts her for COPPE in the hopes of getting her into the group, but fails. The next morning, the girl, named Kurenai Rin, shows up for lessons. Hira declares that the group should aim for Budokan. While the girls laugh, Rin smiles and declares that she'll join COPPE.
