Aoi Tanaka was an average sort of person. She was cheerful, maybe, beautiful incontestably, but average nonetheless. She had average grades, average popularity, average creative abilities. She was just average; normal in fact. Positively ordinary.
It was her utter average-ness that lead her to move countries, this time alone at the age of eighteen, to live with her uncle's son Izumo Kusanagi. This man wasn't quite as average as his cousin, but we'll come to that later.
It was also her average-ness that gave her potential, that allowed her to be part of a world she should not know of. Her complete ordinarity was, in a way, what made her different from anyone else. It is debatable, however, if any of this was a good thing.
This story is a story of Kings and Clans. It is a story of Strains and barmaids. It is a story of happiness. But most of all, this is the story of Aoi Tanaka.
