One night, ten-year-old Sakura Kinomoto stumbles upon a mysterious book entitles "The CLow" while rooting in her father's library. Hidden inside it is a strange deck of cards. Sakura pulls out the topmost card and reads it. Sunddenly, a strong gust of wind blows all but one of the cards around the room, out the window and into the night.
Keroberos, the Guardian Beast sealed within the book to watch over the cards, is awakened by the commotion. He freaks out when Sakura tells him that she accidentally set the cards free. Those cards are no ordinary cards, he explains, they're powerful and dangerous magic artifacts created by the ancient sorcerer Clow Reed, and now the Clow Cards are scattered all over Tokyo! To make up for her mistake, Keroberos appoints Sakura as the Cardcaptor whose duty is to find the Clow Cards and bring them under control - before they end up destroying the world!
Quite a daunting aassignment especially for a 4th-grader from Tomoeda Elementary School. Luckily for Sakura, she doesn't stand alone in her quest to cature the Clow Cards. She has five of her family and friends beside her to lend a helping hand.
The Jack of Hearts. The Jack in a deck of cards used to be known as the Knave and Touya Kinomoto, Sakura's older brother is a right rascally knave. He teases her, calls her names, and play tricks on her all the time! But despite this outward nastiness, Touya cares ery deeply for his little sister. He's actually very protective of Sakura, and thanks to his uncanny sixth sense, he is able to warn her and others when danger is approaching.
The 10 of Hearts. Yokito Tsukishiro is the best friend of Sakura's older brother. He's quite a guy. Not only is he a brilliant student-clubs fight over who gets to have him as a member-he excels in sports too, never failing to help the carsity teams when they're short of players. No wonder Sakura has an enormous crush on him-he's a perfect "10"! It's a rare but special treat for Sakura when Yukito walks with her and her brother to school. Probably the only peculiar thing about Yukito is that he can put away food by the truckload and never gain a pound.
The Queen of Hearts. Tomoyo Daidouji is the quenn of sakura's world, and sakura definitely rules in tomoyo's world! Sheand sakura are classmates and best friends. She is one of the few people who knows Sakura's secret and this excites her to no end. She designs a new costume for Sakura to wear each time she goes card-capturing, and records their adventures on her video camera.
The King of Hearts. Li Syaoran is first introduced as just an exchange student from Hong Kong but later it's revealed that he is also a Cardcaptor with the same abilities as Sakura. Li wants to possess the Clow Cards for himself and will compete many times with Sakura to capture them. Howeveer, as he and Sakura to capture them. However, as he and Sakura learn to respect and understand each other, their competition soon turns to cooperation. Could it turn into something more? Could Li become the King of Sakura's heart?
The Ace of Hearts. Keroberos is Sakura's Ace-up-her-sleeve when it comes to anything magical, owing to the many years he spent as the Guardian Beast of the Clow Cards. Though how this cute little teddy-bear-like creature with wings could ever guard anything effectively is a mystery! Kero-chan, as he is affectionately known, spends his spare time stuffing himself silly with cake and candy, or working out his excess energy on video games.
