xxxHolic ties in with the Tsubasa " at various moments. When it does you often times wonder what is happening and get confused but as you continue reading you tend to pass it off as a side dish. xxxHolic is one of those mangas where you reach the end and you end up wanting to tear the book apart or rip out the screen because you don't want it to end. It has a great storyline and you really enjoy how it plays out. The characters will really get you into the story. The art is some of the best art i've seen and you enjoy every bit of the manga.

You end up loving all the characters, and when it all ends you feel content and even a little sad, but this is one of the best mangas you will ever find so read it!
