I read part of the manga, but I didn't like it. I think this is one of CLAMP's worst.
The story is terrible. I mean, I liked the idea of it - I really liked the City With No People
and used it for a standardized test essay - but the execution was bad. They foreshadow one thing and then have the ending be the opposite!
I mean, the book said the one just for me can't love only me. Guess what happens? GUESS!
Let's just say I'm very, very, very glad I didn't buy it.
The art is great - I'd buy the artbooks, for sure - but good art doesn't redeem a bad story.
