After a brief visit to the remote archipelago of St. Hauda's Land, Ida Maclaird slowly begins to turn to glass and returns, hoping to find a cure, and instead finds herself falling for loner Midas Crook.

During their quest Sakura's memories, Syaoran and Sakura are pulled from a land where two factions battle over the statue of the God of Calamity--into the realm of that very divinity. Suddenly, they find themselves facing their friends across the battle lines of someone else's war.

In order to retrieve Sakura's feathers and save her life, the travelers must sacrifice what they value most to Yuko, a witch who can grant them the power to cross dimensions.
