"Key that hides the forces of darkness, show me your true form! By the covenant, I, Sakura, command you. Release!"
As she finds each card, she has to battle and defeat their magical personification, and then use her staff to turn them back into cards. Cardcaptor Sakura is my favourite magical girl manga series next to Sailor Moon. It has been called one of the best manga series ever created for kids and has been praised by critics for being an artful blend of magical fantasy, romance and drama.
