Miu Takigawa observes the world with quiet contentment from behind her bangs, opting to remain inconspicuous. Despite struggling with social interaction and lacking confidence, she perseveres in her part-time job to support her mother and younger sister, Haru. Unexpectedly, she receives a letter from GIP offering her a place as a candidate in their new project, which she ultimately accepts after much consideration. Meanwhile, an eclectic group of candidates convene at a secret location after being whisked away by a manager, who divulges that they are to follow the directives of a mysterious entity called "The Wall." Soon, Miu and her peers will be introduced as 22/7, a group of idols unlike any other, with a scheduled debut date of December 24th, 2016.
