Story+Idear+II

This story is about a guy (half demon) who is accused for murder after escaping the magical library he works in with one of his friends (half demon). He is accused of murder because he can see things, called Naught, that are somewhat like spirits but almost nobody can see them. He goes on the run with his friend and makes a new friend (half demon). They are followed by a winged half-demon, a kitsune (fox faery), and daughter of a goddess, who try to find them so they don't have to be on the run all the time. Our protagonists also have to save the world from an evil half-demon and an evil (albeit stupid) popstar with a grimoire. This is mostly comedy... because the characters do not get along very well, and some of the situations are just rather strange. It's also kind of fantasy... because of the half-demons.
