Magus of the Library 5  (English, Paperback, Izumi Mitsu)

The Great Library is the center of learning in the world, and its librarians are capable of magnificent feats of magic! In a small village far from the Library, a poor little elf boy struggles against bullies who call him "knife-ears." His only solace: the books he sneaks out of the village's tiny branch library, in which he's not allowed. When a librarian from the Great Library arrives, he's dazzled by her knowledge and glamour. Their meeting will change his life and begin the adventure he's always dreamed of having!
