Animation books are books that are set up like manga. The only difference is, they follow the storylines and script of anime episodes. I, personally, own all the Card Captor Sakura Anime Books in Korean, and thought they were way too cute to not be featured at Clow Legacy. I won't post many details into the anime books, as they're not released in English in any other form from Cardcaptors (which we all know is Satan-incarnate.) :] And, well, if you don't know what "Cardcaptors" is, sometimes ignorance
is bliss.
Apart from actual story and substance, the Card Captor Sakura anime books also include character profiles and information on captured Clow Cards. Each book covers about three episodes. Below are the Japanese covers.
