Okay, here is how I summarized Cardcaptor Sakura... It all starts when Sakura finds a book in a library and opens it. Out fly cards that are called the clow cards. Then the gaurdian of the cards makes Sakura the new Cardcaptor. Sakura now has to find all the cards with Kero, the gaurdian's help so that the cards don't cause trouble in the world. I know it's not much, but I will add on later.
