The Space Empire Zangyakku begins their second invasion of Earth. They set up their fleet headquarters between the Earth and the Moon. On the other hand, Marvelous and co. are told by Navi to "start their treasure hunt on Earth by finding people with black clothes." However, because of Navi's rough navigation, they are having a bit of trouble doing that. Coincidentally, in front of them appears a man.
