Cardcaptor Sakura: The Sealed Card (2000)

All the cards have been captured and transformed, with Sakura and friends settling back into their normal lives. Unfortunately, Syaoran has returned home to Hong Kong without Sakura ever confessing how she felt about him. She gets another chance when he returns to Japan on vacation, but their reunion is interrupted by the reappearance of the Hope Card. Created by Clow Reed long ago to provide a balance to the energy of the other Clow Cards, it is more powerful than anything the Card Captor has ever faced. To capture it, Sakura may have to give up her most precious feeling.
