In a city of the dead, long since ruined and far from human civilization, lives a single human child. His name is Will, and he's being raised by three undead: the hearty skeletal warrior, Blood; the graceful mummified priestess, Mary; and the crotchety spectral sorcerer, Gus. The three pour love into the boy, and teach him all they know. But one day, Will starts to wonder: "Who am I?"
Will must unravel the mysteries of this faraway dead man's land, and unearth the secret pasts of the undead. He must learn the love and mercy of the good gods, and the bigotry and madness of the bad. And when he knows it all, the boy will take his first step on the path to becoming a Paladin.
Ever since watching a magic show held by him and his wife Maeve, Makoto Shiranui has always admired Mamoru Hoshisato—a world-class magician, as well as friend of his parents—and came to Tokyo to become his apprentice. Kana, nicknamed Hatena, is the couple's daughter and his childhood friend. As the hustle and bustle activities in Tokyo catches Makoto off guard such as burglaries by a beautiful thief, he depends on Hatena's comforting side. When he came to Hoshisato's now-haunted mansion to reunite with his childhood friend, he is greeted by the family's butler and maid, Jeeves and Emma along with Hatena, only to discover that they are not as compatible anymore.
