Thanks Sushi-Y for the images
I just want to corect something I said >.<
The 8th volume of the seinen novel will not be released this april but on May 1st (1/5/2006).
The first volume of the new manga will be released on 26/4/2006.
This info should be correct since its according to the publisher :P
Anyway these images from this site:

Illustration from the novel maybe? Anyway I hope the anime's artwork is as good as these (I'm dreaming LOL).
