The D-Cellophane Dセロファン, di serofan?) is an small cellophane made out from a Grathnode Crystal base, which contains the DNA seeds for a Reyvateil, and it's an enhanced version of the HD-Cellophane. Due to being made out from Grathnode, it has similar properties to it, and as such, it can also be Installed and Uninstalled. The D-Cellophane is an essential part of one of the Reyvateil Origins and of all the Pureblooded β-types, due not only to containing part of the data that links the Reyvateil's body with her Cosmosphere, but also because of it being a checksum for the growth of the Reyvateil.
