Cardcaptors (Original title "Cardcaptor Sakura") is an animated adaptation of Cardcaptor Sakura Japanese manga series written and illustrated by the manga artist group Clamp.The series was produced by the animation studio Madhouse aired in Japan on the NHK television network spread over three seasons.
Nelvana licensed Cardcaptor Sakura in North America, which dubbed the series into English and released it under the name Cardcaptors. The heavily edited episodes were reordered, with some episodes left out completely. Potentially controversial material was removed, and the series was refocused to be more action oriented for the appeal of male viewers, as they were seen as the largest audience of animation at the time. Cardcaptors first aired in the United States on Kids' WB between June 17, 2000 and December 14, 2001. It was shown on CITV in the UK, but never went any further than the first half of the second series.
Cardcaptor Sakura begins when ten-year-old fourth grader Sakura Kinomoto accidentally releases a set of magical cards called Clow Cards from the Clow Book, created and named after half-English, half-Chinese sorcerer Clow Reed. Each card has its own personality and characteristics and can assume alternate forms when activated.
The guardian Beast of the Seal Cerberus emerges from the book and tells her it is now her responsibility to retrieve the missing cards. As she finds each card, she battles its magical personification and defeats it to seal it away. Cerberus acts as her guide, while her best friend and second cousin Tomoyo Daidouji films her exploits and provides her with battle costumes. Sakura's older brother Toya Kinomoto watches over her, while pretending that he is unaware of what is going on.
