The book-reading part is probably the most annoying part because it requires more concentration to follow. Mainly because I rarely read those kind of books. Or any book, really. The premise is quite weird – about historical, powerful books. And a mysterious tsundere girl to accompany the main character. And reading the books gives the reader awesome power or whatever while epicly confusing the watcher (or just me?).
Animation etc as expected from Gainax. The story being written by writer of Asura Cryin’ assures some quality in the story albeit probably a bit confusing. Much better than that certain Dark Rabbit, I’d say. The whole Latin thingy is quite pretentious. Japanese sure love their Latin. Or French. Or German.
