Oh. D: How disappointing.
I'm fine with crazy plot twists and all, but they just ... don't make any SENSE. Then Yuuko appears to explain it, and I still can't understand what happened and what's happening. It felt like there was a volume missing in between the Kamui story line and the world where they were playing the Chess game.
I managed to work a few things out with the Fai storyline, because somewhere on the internet, someone actually understood what the heck was going on, but still. But it kills the enjoyment of the story when you're forced to stop reading it and google for information to see if another reader actually managed to follow.
I just wish CLAMP explained it better, and rather than just info-dumping about what each character did and said, I wish they just showed it to us. It would've been less confusing. I love CLAMP, but I just can't make heads or tails of the plot for Tsubasa anymore.
