Cardcaptor Sakura: Clear Card Vol 5

From the Kodansha edition

Seventeen years after the original Cardcaptor Sakura manga ended, CLAMP returns with more magical clow card adventures! Legacies and Futures Sakura finally has a date with her darling Syaoran! She's working hard to make the perfect picnic lunch for him, but on the big day, a strange message arrives, calling Sakura away to her great-grandfather's home. Then, Sakura's late mother appears to her again--perhaps bringing with her the answers to the questions about the hooded figure from Sakura's dreams, and the beginning of the solution to the mystery of the transparent cards themselves...
