From Tokyopop:
Except for her red hair, Youko Nakajima is a typical, obedient Japanese high-school student. Her life is fairly ordinary that is, until Keiki, a kirin in the guise of a blond-haired man, tells her that she is his master and must return to their kingdom. When he mysteriously vanishes, Youko is left alone, confused, and wandering through a foreign land with nothing to help protect her save a magic sword and a magic stone.
When Keiki suddenly appears at Youko’s school, little does she realize that her life is about to change. Lost in a strange land without a map and demons on her trail, Youko begins her quest for both survival and self-discovery.
