xxxHolic is an ongoing manga and anime series created by CLAMP in 2003.  The narrative revolves around a young, teenage boy named Wantanuki and a sake loving witch named Yukko who helps him develop, control, and appreciate his psychic-metaphysical abilities. According to Wikipedia, CLAMP is presently at work on the third installment, xxxHolic:: Rei.   The first two seasons of the anime, including OVAs, were produced by Production I.G. between 2006 and 2010.  The critically acclaimed story line became a "portal" tying  multiple CLAMP-cult classics together within one realm.  It has become my favorite seinen works to date and I hope you will enjoy the series too.
