Tsubasa: RESERVoir CHRoNiCLE Volume 02: 05/07/12
Tsubasa: Reservoir Chronicle by the mangaka group CLAMP is the other side of the xxxHolic coin. It is because of that connection alone that I'm reading the series.
My husband read through about half of this series four or five years ago and made me watch the first disc of the anime which covers books one and two. Then when we got into xxxHolic we went back to Tsubasa: Reservoir Chronicle since the two are so tied together. We've rewatched the anime twice again and after suffering through the anime again I was ready to move beyond this part of the series, even in manga form.
In volume two the group arrives in a place that looks like modern day Osaka and for anyone familiar with Osaka will get all the puns and visual jokes built into the world. Everyone has a spirit animal as protection. These Kudan can be used in battles and are an awful lot like Pokémon. The only difference is that you can't "catch 'em all."
There's also a lot of fighting, drawn out in the fashion you'd see in Bleach or similar. Coming this early on the fighting is a distraction both in the anime and the manga. In the manga it's probably worse because it's basically filler for the book, even when it's obviously being a parody.
