Sakura, Tomoyo, and a Wonderful Song

A rumor spreads at Sakura's school that a ghost haunts the music room and sings at night. At first afraid to investigate, Sakura changes her mind when Yukito comments he would like to hear the ghost sing. Joined by Tomoyo, Kero, Syaoran, and Meiling, Sakura learns the ghost is the Song Card, and the voice she is impersonating is Tomoyo's.
