After successfully capturing every elusive Clow Card and converting them into her own Sakura Cards, Sakura Kinomoto believes her role as Cardcaptor has reached its end. On her way to the first day at Tomoeda Middle School, she is pleasantly startled to encounter her beloved Shaoran Li, who reveals he is permanently relocating to Tomoeda. To her joy, Shaoran will also be a student at the same school.
Though her life seems brighter than before, Sakura experiences a strange dream that night in which she is surrounded by transparent cards and encounters a mysterious figure in a cloak. Upon waking, to her shock, all the Sakura Cards have become clear—her dream has turned into reality. With ongoing prophetic visions, a new staff, and encounters with an unfamiliar set of cards, Sakura must once again embrace her duty as Cardcaptor, accompanied by her guardians and friends, on a brand-new adventure.
