Following the events of Cardcaptor Sakura Movie 2: The Sealed Card, Kero and Spinel (if you don't know who they are, watch Cardcaptor Sakura and the movie first) share a plate of takoyaki (octopus balls). They get into a fight over who gets the last piece, and in the process send it flying out the window. They both chase the takoyaki, and each other, in a mighty effort to be the "takoyaki captor".

During the summer holidays, Sakura and her class are preparing to present a play at the annual Nadeshiko Festival.

But as the cards begin to disappear one by one, Sakura discovers a single cards still remains. One with power equal to all hers... It is during this summer that Sakura faces her final battle.

It's winter vacation and Sakura wins a trip to Hong Kong. Kero, skeptic of her luck in lotteries, questions whether she was merely lucky or was she summoned to Hong Kong upon inevitability. As Sakura strolls through Hong Kong's Bird Street, she senses an evil force calling to her. On chasing two strange birds, she is lead to a phantom world where she learns she was actually made to come to Hong Kong by a woman, Madoushi, who apparently wants revenge on Clow Reed. With Syaoran's mother, Yelan's help and the guidance from Clow Reed's voice, she must fight Madoushi and rescue her friends and loved ones, who have been captured.

The future of the universe rests on one young man, Kamui Shirou, who must destroy either the Dragons of Earth or the Dragons of Heaven - two opposing armies. He alone must decide whether humanity should be destroyed to create a purified universe, or whether it should be protected to preserve civilization. 
 
Two oracles, the sisters Hinoto and Kanoe foresee the coming of the Dragons and predict opposite outcomes. Each sister gathers strength and ammunition to insure her own vision for the future. However, neither sister realizes that there is one man who has an even greater power than the Dragons, and that ultimately he will determine the fate of the earth. 
 
Which sister will prevail and how does Kamui fit into their struggle? The answer to this question will forever affect humanity.
