Kirari Tsukishima is a 14-year-old beauty with a gluttonous appetite. She pays no mind to idols or the entertainment industry, as her thoughts are consumed by food. This obsession leaves her completely oblivious to matters of the heart. One day, after rescuing a turtle stranded in a tree, Kirari meets Seiji, a handsome and gentle boy. To thank her for saving his pet, he gives her a ticket to a concert by SHIPS, a popular idol group. Kirari rushes to the venue, where she encounters another boy who tears up her ticket. He warns her to stay away from Seiji, claiming they live in different worlds. Furious, Kirari sneaks into the concert, only to discover that Seiji and the boy who destroyed her ticket, named Hiroto, are actually members of SHIPS. Now grasping the meaning of "different worlds"—Seiji is a famous idol, while she is an ordinary middle school student—Kirari refuses to back down. Driven by the determination to be with Seiji, she declares that she will become an idol herself.
