is a
shonen manga series written and illustrated by the
manga artist group
Clamp. It takes place in the same
fictional universe as many of Clamp's other manga series, most notably
xxxHolic. The plot follows how
Sakura, the princess of the Kingdom of Clow, loses all her memories and how
Syaoran, a young archaeologist who is her childhood friend, goes on a quest to save her. Dimensional Witch
Yuko Ichihara instructs him to go with two people,
Kurogane and
Fai D. Flowright. They search for Sakura's memories, which were scattered in various worlds in the form as feathers, as gathering them will help save her soul.
Tsubasa was conceived when four Clamp artists wanted to create a manga series that connected all their previous works. They took the designs for the main protagonists from their earlier manga called
Cardcaptor Sakura.
