Announced earlier through a jacket insert of the 7th volume of the light novel, nothign else was said. Really, there is no information on cast, company, or even a date. We are left in the dark about what to expect in terms of a quality transition from words to anime.
The story is about a guy that is supposed to end up being the Devil King. Well, of course with any magical story thing book, he has like 4 girls after him since this is a book from Japan. A girl that “hates”, a girl that wants his body, and an android girl. So, in a way, its like Zero no Tsukaima I guess.
