"22/7" is an anime and manga series that revolves around a group of young women who are brought together to form an idol group under mysterious circumstances. The narrative begins with the protagonist, Miu Takigawa, a reserved and introverted high school student who receives a letter from a shadowy organization known as "The Wall." The letter instructs her to attend an audition, which she reluctantly does, only to discover that she has been selected as one of eight members of a new idol group named "22/7."

The group's formation is overseen by a cryptic figure referred to as "The Manager," who communicates with the girls through a digital interface and provides them with directives. The Manager's true identity and motives remain unclear throughout much of the story, adding an element of intrigue. Each member of the group is chosen based on their unique talents and personalities, and they are required to live together in a shared dormitory while undergoing rigorous training to prepare for their debut as idols.

The series explores the personal struggles and growth of each member as they navigate the challenges of the idol industry. Miu, initially hesitant and unsure of her place in the group, gradually opens up and forms bonds with her fellow members. Other key characters include Sakura Fujima, a cheerful and optimistic girl who serves as the group's emotional anchor; Nicole Saitou, a half-Japanese, half-American member who struggles with her identity and self-worth; and Ayaka Tachikawa, a former child actress who faces pressure to live up to her past success.

As the story progresses, the members of 22/7 confront various obstacles, both individually and as a group. These include internal conflicts, external criticism, and the demanding nature of their profession. The narrative delves into themes of self-discovery, perseverance, and the importance of camaraderie. The girls' journey is marked by moments of triumph and hardship, as they strive to achieve their dreams while staying true to themselves.

The series also incorporates elements of mystery and science fiction, particularly through the enigmatic presence of The Wall and The Manager. The Wall, a massive, sentient structure that appears to have a will of its own, plays a significant role in the group's formation and development. Its origins and purpose are gradually revealed, adding depth to the overarching plot.

"22/7" balances its focus on character development with the broader narrative of the idol industry, offering a nuanced portrayal of the pressures and rewards of pursuing a career in entertainment. The series is notable for its blend of emotional storytelling, interpersonal dynamics, and speculative elements, making it a distinctive entry in the idol genre.
