Cardcaptor Sakura

Ten-year-old Sakura Kinomoto is a fourth-grade student living in Tomoeda, but her ordinary life is turned upside down when she discovers a mysterious book of cards called "The Clow." When she inadvertently scatters the cards throughout the town, a magical gust of wind is unleashed, and the Beast of the Seal, Keroberos, appears. Kero informs Sakura that she has released the powerful "Clow Cards" created by the sorcerer Clow Reed, which must be recaptured to prevent them from causing harm.
