Serrel is a boy who plays with Fiona, the third princess and his childhood friend, while working as a librarian at the magical library in the Kingdom of Sneiers. During his hectic but enjoyable days, he is asked by the Dukes of Bernard to find a way to cure their beloved daughter Zion's illness, and he accepts the request. After examining her body, he discovers that she is under the influence of a curse spell, and Serrel immediately begins to search for a cure. He is soon searching for a cure when word arrives that she has suddenly taken a turn for the worse. Unable to find a cure, Serel attempts to cancel it out with lightning magic, but the cursed mark notices this and takes over Serel's body... This is the start of a biblio-fantasy about the books in a large library.
