Some time ago, the influential and powerful Toue Inc. bought the island of Midorijima, Japan, with the plans of building Platinum Jail—a luxurious utopian facility. Those who are lucky enough to call it home are the wealthiest citizens in the world. The original residents of the island, however, were forced to relocate to the Old Residential District; and after the completion of Platinum Jail, they were completely abandoned. "Rib" and "Rhyme" are the most common games played on the island. Rib is an old school game in which gangs engage in turf wars against each other, while Rhyme is a technologically advanced game wherein participants fight in a virtual reality. To be able to play Rhyme, you must have an "All-Mate" (an AI that typically looks like a pet), and the match must be mediated by an "Usui." Aoba Seragaki has no interest in playing either game; he prefers to live a peaceful life with his grandmother and All-Mate, Ren. However, after getting forcefully dragged into a dangerous Rhyme match and hearing rumors about disappearing Rib players, all of Aoba's hopes of living a normal life are completely abolished.

Due to his cheerful personality and ability to smile even through a hard day's work, Kanade Amamiya is suddenly scouted into the idol life by industry legend Haruto Mikami. He joins the agency D-4 Production where he meets fellow high schoolers Shin Oikawa, Junya Sasaki, Itsuki Katagiri, and Chizuru Sawamura, who all aspire to become idols. Inspired by their determination, Kanade embraces this new life. A perfect chance for his debut appears when they are grouped together to perform at the company's Dream Festival. To rise to the top, they must collect Dorika—cards given by the audience that idols use to form their stage outfits—and gain the audience's attention. However, the road to fame is a rocky one, and the boys must form a bond of friendship and trust before they can reach their goals. [Written by MAL Rewrite]
