xxxHolic: More Than A Mystery Anime?

When I watched this anime, I already had an idea that it was related to other anime series by the same creators. Clamp is known for creating crossovers for their series. This series was no different. However, the series itself did not involve any crossovers. When you watch this series, you realize that Watanuki Kimihiro is not just any high school student, but a specially gifted one. He realize that he was specially chosen to help Yuuko run her shop. The reason for this is explained in the Tsubasa series cross-overs. I do have to say though, I would hate to have Watanuki's gift because I don't think I could deal with the constant pressure of seeing what he does. Do you think you could or would it drive you to the brink of insanity?
