She was just going to run an errand on her bike, but before she knew it, it was a big war in space! "Oone Nana" is an ordinary girl who eats a lot and gets a job at a small factory in Osaka called "Daikon Co." One day, while busy preparing for a new product launch, Nana is given a secret mission. It's a simple job of just bringing new products by bicycle. But... After eating a lot, while she goes to the toilet, an unknown enemy from space attacks the Earth, and it's already in trouble... Nana ends up flying into space wearing the new product "Pomba 8000 Universal Space Suit" of "Daikon Co.", which is actually a company with amazing technology. Her only goal is to eliminate the threat from space and hold the new product launch without a hitch? Well, maybe to protect the Earth. Will Nana, who doesn't have a very high sense of mission, be able to protect the Earth? A big entertainment movie where okonomiyaki and space intersect!
