The series is centered around a high school lit club with slightly unusual members...its president, Touko, is actually a demon that eats stories. Literally. The second member of the club, a boy named Konoha, writes stories, from daily shorts for Touko's consumption to an award-winning novel written under a pen name. The popularity of the novel stresses Konoha out, though, and he's become a bit of a shut-in as a result.
The anime will be a theatrical film, but no release date or other information has been announced...yet. I'm looking forward to it though, because I remember thinking the series sounded interesting the first time I reported on it!
