Second season announced
The second season of Spice and Wolf (the correct name, in both English and Japanese) has been announced as of October 5, 2008.
The same director and writer will return, but the art & animation has been handed over to Brain Base, instead of IMAGIN which did the first season.
Season 1 covered two books of the eight-book light novel series. Speculation by fans based on the content of the novel series implies that the second season should cover the next two books.
There's no indication on when season 2 will be aired in Japan.
