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. On the roof, Tomoyo performs the song, which the Song Card joins in with, allowing Sakura to catch it. Forgetting she was supposed to record the voice for Yukito, Sakura asks Tomoyo to perform again.
