Following the success of Shiny Colors' first concert, Mano Sakuragi and her friends continue to face new challenges. After Straylight, a new unit of 283 Production, makes its debut concert, the members of the units are temporarily shuffled into new groups to prepare for a Halloween event to help them grow individually as idols. While Mano struggles to express her ideas, her fellow unit member Hiori Kazano feels left out by her new comrades' talent. At the same time, Fuyuko Mayuzumi, who has bitterly failed to become Straylight's center, proves completely unable to show her real personality, jeopardizing the entire project in the process. Shiny Colors' producer will have to find a way for Fuyuko to break out of her shell if he wants to see his idol units illuminate the world once more.

Mysterious immortal humans known as Ajin first appeared 17 years ago in Africa. Upon their discovery, they were labeled as a threat to mankind, as they might use their powers for evil and were incapable of being destroyed. Since then, whenever an Ajin is found within society, they are to be arrested and taken into custody immediately. Studying hard to become a doctor, Kei Nagai is a high schooler who knows very little about Ajin, only having seen them appear in the news every now and then. Students are taught that these creatures are not considered to be human, but Kei doesn't pay much attention in class. As a result, his perilously little grasp on this subject proves to be completely irrelevant when he survives an accident that was supposed to claim his life, signaling his rebirth as an Ajin and the start of his days of torment. However, as he finds himself alone on the run from the entire world, Kei soon realizes that more of his species may be a lot closer than he thinks.

For high schooler Kei—and for at least forty-six others—immortality comes as the nastiest surprise ever. Sadly for Kei, such a feat doesn't make him a superhero. In the eyes of both the general public and governments, he's a rare specimen who needs to be hunted down and handed over to scientists to be experimented on for life—a demi-human who must die a thousand deaths for the benefit of humanity.
