The futuristic cyberpunk world the Clover characters inhabit is one of amazing technology. One can have a prosthetic arm one moment, then have a long, cybernetic sword the next. Illusion and reality are no longer at odds with each other, but instead work hand in hand. Like many of Clamp's works, fate takes a hand...
In the first volume, Kazuhiko has been asked by the military he formerly worked for to take a 'special package' to an unknown place. Until he arrives where the 'package' is located, he doesn't even know what it is. When he gets to this mysterious package, he finds that it's actually a young a girl. This girl, named Suu, is special - a 'four-leaf clover' - something which should not exist, but does. Outwardly, however, and except for the rare occasions in which she uses her own mechanical wings, she appears to be a perfectly normal girl with a strange and sad loneliness, and with a special wish to go to a certain place.
The artwork is clean and sparse (in a good way). It's not filled to the brim with images like Clamp's usual works (which I also adore). This serves to reinforce the mood of isolation and gives the whole manga a film-like feel. A beautiful work that any fan of cyberpunk, Clamp or excellent stories/art will enjoy.
