About the loosing bodypart thingie... Isn't it strange that no other deadman has lost any bodypart? They all seem to be "fully equipped," even though, while listening to Crow, it sounds like they've fought each other before.

Seeing as how this manga is extremely dark, I wouldn't be surprised if they can buy their body parts back, or at least buy somethin to replace it.

There is also the possibility that they've never lost yet...or they lost something we can't see like an internal organ...
