Tsubasa: Reservoir Chronicle 09: 09/18/15
Tsubasa: Reservoir Chronicle 09 by CLAMP ends the Ashura and Yasha story. It's also the furthest I've gotten in the anime.
For me, Volume 9 was a high point in the series, that I've read so far. I like the time travel aspect and the consequences of Syaoran's actions, namely in the ability to change the world of Shara.
There's also an interesting parallel with the Rô part of xxxHolic. The battle on the moon is a static one, the two sides stuck in battle because of one of the two sides refuses to acknowledge that things have changed.
The big bad, Wong-Fei and company, continues to scheme. While I'm sure this subplot will blossom into something big eventually, right now it feels more like a distraction than actual advancement in the story.
