Sakura is invited to the high school culture festival. She meets Tomoyo and Syaoran there and watches a play by Yukito and Toya's class. During the play, a corrosive mist forms outside the auditorium and enters through the vents where it destroys the stage and puts Toyo and a girl named Yoko in danger. Sakura and Syaoran head towards the lighting room where Sakura summons the Shadow Card to capture the Mist Card, Syaoran using a wind elemental to save Toya and Yoko. Toya gently rejects Yoko's feelings, since he is in love with Yukito.
