I'm a librarian who loves anime, manga, and reading a wide variety of genres.
What carried me through this volume was my memories of liking the first few episodes of the anime. So far, the manga isn't very promising. The characters are composed of a single joke slapped onto pretty character designs: the ninja teacher who's deathly afraid of traveling in vehicles (he even hates using bicycles); Raimei, who keeps mistaking people for being someone else; Miharu and his devilishness and massive indifference. As far as I can remember, the anime characters weren't any different, but for some reason it was more fun to watch them than it was to read about them.
