Tsubasa Chronicle

[RyougaZell]

If you can, check the whole manga. Its not that long anyway.
The anime did cover all the arcs, but also made a lot of filler.For instance, returning to several worlds was filler, alongside the bus arc and the like.

The manga has more detail and more direct crossovers with xxxHoLIC

I was looking forward the next arc after Tokyo, since it involved Eagle, Lantis and Angel-Hikaru (from Angelic Layer). Plus a Gothic-Lolita Sakura... bleh.

And... without spoiling... the latest chapters and revelations have been fantastic in the manga.

EDIT:

There are currently 206 chapters. The manga is on its final arc actually.

The "Tokyo Revelations" arc began on chapter 107 and ended on chapter 135. But I still recommend reading them all.
