From Kodama:
An alien named Mumu is a survivor of a civil war that saw the destruction of his planet's scientists, leaving only its fools alive. In an attempt to understand the advanced technology his people left behind, he's infiltrated earth, a planet with a lower level of civilization, to study their so-called "home appliances," which contain facets of all technological knowledge. So begins the adventures of Sakurako, a university freshman and Mumu's new and unexpected accomplice, as she navigates a wild and exciting campus life.
