Arisou de NASA-Sou manga, Probable Improbable ありそうでNASA荘 Two American dudes believe themselves to be aliens, so when they end up coming down to Earth from their Moon base, they do and say all kinds of weird shit because they don’t understand how human society works, as you’d expect. Hijinks ensue. Arisou de NASA Sou introduces itself as a heartwarming “space comedy” with some ecchi thrown into the mix for good measure, but it doesn’t actually have too much to do with space or actual astronaut things and the majority of the story revolves around everyday scenarios such as going to the beach, the zoo, etc.
