Cardcaptor Sakura (kādo kyaputā sakura), also known as Card Captor Sakura (with the space) and often abbreviated to CCS, is a manga series from the well-known all-women artist team CLAMP. It is also an anime show (1998-2000) created from the manga, consisting of 70 half-hour episodes in three series and two theatrical-release movies.
The series begins as a simple girls' anime of the magical girl genre (similar series include Sailor Moon and Pretty Sammy). Ten-year-old Sakura Kinomoto opens a mysterious book in her father's study and accidentally lets loose the magical Clow Cards. As she lost them, it is her job to retrieve them, which involves finding each card and battling its magical personification. She is assisted by Cerberus (a.k.a., Kero-chan), the beast of the seal assigned to protect the cards, but who was asleep when Sakura opened the Clow book. Kero-chan, who appears throughout most of the series rather like an animated plush toy, makes Sakura into the Cardcaptor and gives her the key of the seal which allows her to fight and capture the cards.
