When they arrive Syaoran, Princess Sakura and Mokona are separated from Kurogane and Fai, who are confronted by the King's warriors and captured. Syaoran, Sakura and Mokona meet Koruri, who introduces them to her princess (an alternate version of Princess Tomoyo). Tomoyo tells Syaoran's group that the king (her uncle) oppresses the country's citizens, seizing their birds and planning to seal the country with a key.
