At an art museum trip, Sakura witnesses a boy attempting to change a painting. During the commotion, she couldn't hear anything and Cerberus is sure that it was caused by a Clow Card, the Silent card. Sakura sneaks out of the house at night and into the museum where they meet the boy from earlier also sneaking in. The boy, Yūki Tachibana, explains the painting is by his deceased father and his mission is to restore the painting which a Clow Card has covered up. Every time Sakura attempts to capture the card, it transports the group outside. Using the Shadow card, Sakura is able to silently capture the Silent card from a distance restoring the painting and discovering Yūki is actually a girl.
