Sakura and Tomoyo's Vanished Voice

Tomoyo has a singing competition coming up soon and is always practicing at school, where a mysterious light seems to be following her around. After cheerleading practice one day, Sakura decides to go listen to Tomoyo practice. On the way there she senses a Clow Card. The Voice Card appears and rushes into the room and steals Tomoyo's voice. She is taken to the hospital. Tomoyo is allowed to go home. Sakura and Shaoran visit her and Sakura blames herself for what has happen, but Tomoyo shows that it wasn't her fault. Shaoran then comes up with a plan to use the Song Card to sing in Tomoyo's voice so lure the card to them.
