Also known as: Sakura Kinomoto (Japanese name), Monster (by Tori)
Sakura is...well, was, your normal 5th grader at Readington Elementary until one day she came upon a book titled The Clow. After she opened it and set the cards free, her life will change forever. From the book emerged Keroberos, and he appointed Sakura a cardcaptor, for the cards would cause chaos if not captured soon.
Also known as: Touya Kinomoto (Japanese name)
Tori is Sakura's older brother who has a sixth sense. He can see dead people. He knows that their mother, Natasha, watches over them. But it's because of the stories he told Sakura about the ghosts he sees when they were young that made Sakura scared of ghosts.
Also known as: Fujitaka Kinomoto (Japanese name)
Aiden is Sakura and Tori's father. He is an archaeology professor. His wife, Natasha, has died, but he and Tori would still talk about her like she's still alive. He always put a different picture of Natasha up everyday since Natasha was a model, so there's many pictures of her. Even though his wife died, he doesn't show any signs of looking for another wife, which is really sweet, don't you think? Aiden isn't all he appears to be, but even he doesn't know that. I'm not going to say anything because this information wasn't shown on those little bits Cartoon Network showed us of Cardcaptors. ^_^ I don't want to spoil you!

Natasha is Sakura and Tori's mother. Even though she died, she still watches over them, and even talk with Tori because he has a sixth sense and can see her. Natasha used to be a model, as a result, has many photos of her. Aiden puts a different one up everyday. Natasha was quite young when she got married to Aiden, but that doesn't matter to the lovebirds. ^_^ Isn't that sweet?
Also known as: Cerberus (Japanese name), Kero (from Sakura), Kero-chan (from Japanese Sakura)
Keroberos is the Guardian beast created by Clow Reed to guard the Clow Cards, but he fell asleep and Sakura opened The Clow and set the cards free. Keroberos then assigned Sakura as Cardcaptor to capture the cards back. Keroberos' real form is a lion without a mane, but you see him as a stuffed animal with wings because the two cards that powers him, the Firey and the Earth, isn't captured yet, so this is his temporary form.
