Akazukin-kun no Shuuchaku

A girl named Anzu desires a prince who arrives on a white horse. She discovers a strange book in the school library, and upon opening it, the characters from Grimm's fairy tales, who had been trapped inside, are freed. The story becomes a blend of a dark and emotional fairy tale and a school-based fantasy, involving a yandere version of Little Red Riding Hood and a girl who is fond of books and daydreams.
