Sakura Kinomoto's about to start middle school, and everything's coming up cherry blossoms. Not only has she managed to recapture the scattered Clow Cards and make them her own Sakura Cards, but her sweetheart Syaoran Li has moved from Hong Kong to Tokyo and is going to be attending her school! But her joy is interrupted by a troubling dream in which the cards turn transparent, and when Sakura awakens to discover her dream has become reality, it's...

Sakura is thrilled her father has time to come to parents' day at school, as is Akiho when Kaito agrees to go. But he doesn't seem interested in the classes, so what is he really after? How is Sakura creating Clear Cards? And why did Yuna D. Kaito come to Tomoeda in the first place?

In order to protect Sakura from Yuna D. Kaito and his mysterious, powerful magic, a familiar face returns to Tomoeda to support Cerberus and Yue. Meanwhile, Syaoran reveals the secret he's kept long hidden from Sakura. Then, Sakura finally learns the origin of the clear cards -- and what their sudden appearance means about her own magical powers.

As Yue confronts Syaoran about the secrets he's been keeping from Sakura, Sakura grows closer to Akiho. In order to help draw her solitary, book-loving friend out of her shell, Sakura invites Akiho over to show her her father's library. But when a powerful, unknown magical force suddenly descends upon the two girls, Sakura discovers that there may be more to her friend than meets the eye...
