Bungaku Shoujo

The Book Girl series centers around Konoha Inoue, one of two members of his high school's literature club, which he joined shortly after entering school, though the story begins when Konoha is already in his second year. The other member and president of the club is Tohko Amano, a third-year girl who loves literature. Tohko is a yōkai who eats stories by consuming the paper they are printed on, and Tohko often asks Konoha to write her short stories as "snacks". (Source: Wikipedia)
