Under the Moon: Crescent

Ashe is the Devil's daughter — sheltered, pure, never having left the castle or spoken to boys. She does not have enough power to inherit the position her family has held for generations. When the current Devil weakens and succession becomes necessary, word arrives that someone living in the human world has been nominated as the next Devil. Before anything can happen, a terrorist attack forces Ashe and a companion named Kyle to flee. They fall through a hole into the human world and lose their magic. The nominees turn out to be twin brothers, Leni and Seizh — both of whom have no interest in taking the position. With human hunters starting to search for devils, Ashe and Kyle move in with the twins. The twins, it seems, have a secret.
