22/7 (Nanabun no Nijyuuni)
Miu Takigawa gets a strange letter one day, informing her she's been selected for a mysterious new project. Skeptical but curious, she goes to the address listed, where she meets seven other girls who received the same summons. Together, they discover a massive, hidden facility. Before they can make sense of it, they're told: "You'll debut as an idol group under a major label." Confused and overwhelmed, the girls realize they're about to become something entirely new-an idol group unlike anything seen before.
