In the Reborn manga, being hit with a Dying Will bullet kills you, and you are "reborn" from inside your own body, leaving a carcass behind. You can see multiple times in the manga that it's not just the clothes that are left behind, but the person's "shed skin" as well.
As far as I remember, nobody ever acknowledged this through the entire run of the series.
Are the bodies left when a person is hit by the Dying Will bullet ever explained?
