Book Girl from 円プレス - Yen Press

I found this an interesting premise: a demoness who must eat books in order to stay alive. Naturally, she's got a gourmet taste for books and stories. Handwritten are the best. I don't know anything else about it but may check it out to read more. From Yen Press. Book Girl

BOOK GIRL AND THE SUICIDAL MIME by Mizuki Nomura  July 2010 | ISBN: 978-0-316-07690-6 | $8.99 ($10.99) | 192 pages | 5.5”x 8.25″ For Tohko Amano, a third-year high school student and self-styled “book girl,” being the head of the literary club is more than just an extracurricular activity. It’s her bread and butter…literally! Tohko is actually a literature-gobbling demon, who can be found at all hours of the day munching on torn out pages from all kinds of books. But for Tohko, the real delicacies are hand-written stories. To satisfy her gourmet tastes, she’s employed (rather, browbeaten) one Konoha Inoue, who scribbles away each day after school to satisfy Tohko’s appetite. But when another student comes knocking on the literary club door for advice on writing love letters, will Tohko discover a new kind of delicacy?
