Except for her red hair, Yoko Nakajima is a typical, obedient Japanese high-school student. Her life is fairly ordinary—that is, until Keiki, a unicorn in the guise of a young blond-haired boy, tells her that she is his master and must return to their kingdom. When the boy mysteriously vanishes, Yoko 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 Yoko’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, Yoko begins her quest for both survival and self-discovery.(Source: TOKYOPOP)

When only an eggfruit, the kirin of the En Kingdom, Rokuta, was transported to Japan for his own protection. But he was abandoned soon after birth by his surrogate parents, left to fend for himself in the mountains. It just so happened that at the same time, a young boy in the En Kingdom named Koya was also abandoned by his own parents, after which he was raised by demon beasts. Their similar circumstances aren't the only thing to bind these two boys, though. Twenty years after their abandonment, their destinies intersect, with potentially disaster consequences for the En Kingdom.(Source: TOKYOPOP)
