Sakura opens a book and releases clow cards, cards with special powers that can cause plenty of trouble if they are just running loose.. So anyway Sakura and her friend Tomoyo get together with a cute lil creature named Kero! Sakura learns how to capture cards and use them to capture other cards, and she goes about capturing cards and making friends..etc. Tomoyo makes her some nice outfits and has a camcorder and records her fights.. that's really all I know.
