This is the sequel to xxxHolic. Now unfortunately, I haven't watched xxxHolic in quite some time so I forget the way things went for the most part but I decided to download the torrents for xxxHolic: Kei when I found out there was a second part to it. From what I can tell, its a continuation from the starting.

Watanuki is slowly learning lessons Yuuko-chan's way and of course, with something more behind what she does than she initially states.

Anyone else seen the full series? I'm still working on it myself and attempting not to spoil it for anyone who hasn't yet. I'm not too sure what to make of it though. It doesn't seem to be getting me giddy like most of my other anime do. Usually if I really like one, I'll spend hours upon hours of watching it until its done.
