Sakura and the Dangerous Piano.Exhausted from the events of the other night, Sakura remains in bed and sleeps into the afternoon before being visited by Syaoran and Tomoyo. Kero explains that Sakura used a great deal of power to transform the Clow Card, explaining her sudden tiredness. Since the Fiery Card was transformed to be under jurisdiction of Sakura's power, Sakura's friends henceforth transform the cards into "Sakura Cards". Later at school, Sakura overhears Eriol playing the piano and has Tomoyo sing to his music; unbeknownst to them, however, Eriol enchants the piano while he plays. While waiting for Tomoyo to finish practicing her song, Sakura and Syaoran find her being attacked by the piano, which has been brought to life; in addition, Sakura senses Clow Reed's presence in the piano. Discovering that the piano is being lured to Tomoyo's voice, Sakura lures the piano to the roof of the school, transforms the Song card and uses it to mimic Tomoyo's singing, tricking the piano into falling off the roof and smashing on the ground.
