Itsuko a budding star on the 2035 equivalent of YouTube. As she sings, dances and muses for the webcam in her bedroom, comments from fans flash all over her futuristic transparent computer screen.
All is not well in Itsuko’s world, however. Years ago a pandemic emptied out Tokyo, which is now a no-go zone, and fleeing residents built a replica of the city in western Japan’s Kansai region. Even worse, a giant meteor is scheduled to strike the planet and end life as we know it in 10 years. What’s a girl to do?
Itsuko has a vision of stopping the meteor with her bare hands. Then, in a barren concrete industrial wasteland she encounters two odd girls in skimpy get-ups: Rainy and Irony from the planet Jupiter. They tell Itsuko she has special powers, and make her an offer that involves the salvation of the planet and requires the skill set she developed entertaining the Internet masses.
