The Cloak of Contents is the robe worn by Death, then his son Death the Kid upon his ascension as a full Shinigami. Not much is known about the cloak, though it seems to have mysterious properties such as being able to mysteriously have anything underneath it hidden. It also gives Death an eccentric appearance and seems to support his own powers and abilities. It may also be a piece in which is only worn by a full shinigami with three of the Lines of Sanzu connected on them.
