Cardcaptor Sakura
Cardcaptor Sakura is a magical girl and romance game that also includes trading cards. Sakura Kinomoto, a 10-year-old girl from Tomoeda, accidentally releases mystical cards known as Clow Cards from a book in her basement.
Cerberus, the card's protector, chooses Sakura to find them. She sets off alongside her best friend, Tomoyo Daidouji, to confront and seal each card's magical incarnation. The original manga had 19 cards, whereas the anime had 52, and Sakura eventually produces a 53rd card. The series was later adapted into two films in 1999 and 2000.
