But when Sakura opened the book, it was empty. Talk about disasters!! Cerberus, the Creature of the Seal, emerged from the cover of the book and told Sakura the cards must be returned to the book. "If the cards aren"t in the book, they come to life and do evil!" Kero formed a contract with Sakura making her a Cardcaptor and together with Sakura"s best friend, Tomoyo, they embark on a mystical journey to capture all the Clow Cards before the Cards can wreak chaos and destruction.
