Sakura decides to get her own teddy-bear-making kit at the craft store where she sees Eriol buying several spools of string. That night, Sakura and Kero once again sense Clow Reed's presence and meet up with Syaoran and Tomoyo. However, Syaoran's body begins moving against his will and attacks Sakura. Fortunately, he is able to cast a water spell around himself, revealing a set of invisible strings controlling his movements, which Sakura cuts with the transformed Sword card although yet again, she is left exhausted by the effort.
