xxxHolic is a pritty good manga and one of the masterpieces of Clamp. That said, everyone that is a fan of Clamp, should know and should be reading this manga. For the rest of the community of readers out there, like me, should give it a try to see if this manga is your taste, even if you dont like Tsubasa Chronicle. This manga shows a different perspective of Tsubasa Chronicle. Therefore, you will see characters showing up in this manga once in a while.

The main story goes around a shop that grants your wish in exchange of something. And everyone that has a wish will be able to enter to this shop. It may look simple but its very complicated. Simple as, if your wish is big then the price will be huge. And complicated as, your wish not always goes as you plan it to and sometimes if you dont realize whats happening, then it will turn very ugly. Moreover, every wish comes with some consequence and responsibility. The manga starts slow trying to explain important aspects such as having a name, destiny, wishes, and change. The story gets very complicated as the story progress and it is easy to notice that

If anyone have seen Clamp's manga, like Sakura cardcapter, then you already know how the art/drawing is. My interpretation of Clamp art is that they make it very elegant and sometimes way to elegant with flashy, puffy, good looking art. Of course, this is mainly for girls and teenagers.

The characters are very well made. Each character is special and has its own qualities. Watanuki is the main character of this manga. Even though he doesnt know it, he is part of something big, as you may have notice from the clues and words from Yuuko that made you wonder whats happening behind the scenes.

Overall, I should say that this manga is great, but I get the feeling that its to classic or its easy to predict the ending (maybe I am reading to much mangas this days).

Oh, btw, if you really liked it, give a try at Tsubasa Chronicles to fully understand what is happening.
I hope you enjoy it and fall in love with Yuuko, hahah...
