In the year 2025, Earth is abuzz with excitement over the Saga Expo. Franchouchou is appointed as the event’s ambassador and begins preparing for the main event: a grand live performance at the SAGA Arena.
But suddenly, a massive spaceship appears in the skies above Saga and launches a full-scale attack across the prefecture. The members of Franchouchou are thrown into panic. Is there really nothing ordinary idols can do in the face of such a crisis…?
Just then, the legendary Tae Yamada—the only one who hadn’t regained her self-awareness as a zombie—awakens. Declaring her departure from Franchouchou, she heads alone into enemy territory to put an end to the invasion.
Can the now-splintered Franchouchou come together once more, restore their bond, and save Saga!?
