Sakura and Syaoran lead quiet lives in the desert nation of Clow. Although the King disapproves of the growing romance between the princess and her archaeologist friend, their days stay happy, if somewhat monotonous. That changes quickly when Sakura appears before Syaoran in a trance, with wings on her back. As the wings turn into feathers and Sakura falls unconscious, Syaoran is driven to act. Syaoran soon discovers that he must gather Sakura's feathers, which have been scattered across various realms, to save her life. After striking a deal with the Dimensional Witch Yuuko Ichihara, Syaoran joins forces with Mokona Modoki, a creature capable of traveling between realms. Also joining him on this journey are Fai D. Flourite, a carefree man escaping persecution in his home world, and Kurogane, a swordsman compelled to travel to hone his strength and character. Together, this strange alliance strives to recover Sakura's feathers—regardless of how impossible it seems to find them all.
