All Star After Secret expands the story with four senior idols joining the seven juniors for a total of eleven routes. The Quartet Route picks up after the events of All Star with Nanami Haruka already in a relationship with her chosen senior—continuing the story of what comes next for a couple who has already found each other. The Rainbow Route covers the same ground with the seven junior idols, each now a fully-established performer, with Haruka living the sparkling daily life that their shared success has made possible.
