Tokyo 7th Sisters

Tokyo 7th Sisters takes place in 2032, after the retirement of the legendary idol unit 7th Sisters. This event marks the end of the idol industry, or so it seems. Two years later, a new idol studio called Nanastar is established in Tokyo, with a young employee as its leader. The city's perception is that idols are a relic of the past, and Nanastar initially struggles to gain traction. A manager appears, proposing the creation of new idols, and emphasizes the importance of strong bonds between the group members, who come to be known as the Nanastar Sisters.
