Ghost Wrapping Paper, formally known as Ghost Shroud (おばけふろしき, Obake Furoshiki), is a demon born from an exceptionally magnificent cloth that lay unused until gaining sentience. This ghostly entity manifests as a soft, white cloth emitting a beautiful aura, possessing comfort, silkiness, and notable durability. Its form features distinct cat-like eyes, sharp teeth, and small arms near its eyes.

Generally cooperative and benign, it willingly assists other demons within the Demon Castle. However, it harbors intense hostility toward Princess Syalis, who systematically decapitates it to harvest its durable material for bedding like sheets and pillowcases. This exploitation creates a cyclical conflict: the princess kills the shroud for materials, it resurrects, and then seeks revenge. Its primary combat method involves constricting adversaries to death.

Ghost Wrapping Paper's existence revolves entirely around this recurring struggle. Its former preoccupation with a "lack of presence" has been entirely consumed by its fixation on the princess, defining its role as both a resource for her sleep projects and an agent of vengeance.
