Translated from the Japanese. "First published in serialization and subsequently in book form by Kodansha Ltd., Tokyo in 2004"--T.p. verso "xxxHolic crosses over with Tsubasa. Although it isn't necessary to read Tsubasa to understand the events in xxxHolic, you'll get to see the same events from different perspectives if you read both." This book is printed "manga-style" in the authentic Japanese right-to-left format.
