Yeah, count me in as Shiori fans as well. I mean, the whole shy and intelligent library girl, with the love for books and spending time mostly thinking in her head, trying to form sentences, it really resonates well to me. Perhaps I'm biased because of that, but I don't feel the episode is dragging, sure the whole thinking on her head and books are (everything) may seems long, but it fits her character. But really, not only does the library is amazing to be that big, what's more amazing is that Shiori has read through them all...Is that even physically possible?
Oh, and of course: Firetruck! Firetruck! F
