xxxHOLiC is pretty much an amazing series.It kind of crossovers to Tsubasa,late in the manga,and in the second and third(OVA) seasons of the anime,but personally,I love xxxHOLiC the first has different arcs or different escapades.But,the art and animation,not so good,cause almost every one looks like trees,and the animation is somewhat lowbudget...

Now,CLAMP has impressed me "once" again,with this very mystical series,and the Openings,and endings,background music,and plot is interesting.

Overall,its something you might enjoy watching.10(Masterpiece)
