Duke Nungsis is one of the Undying Lords[1] and a member of the Flesh Cutters Guild.[2]
He was near the entrance of Hell 71 when White Chain brought Allison to see Cio. Allison, overwhelmed by the alien crowds, bumped into him, prompting the Duke to loudly protest in unintelligible Universal Metaconstant. His assistant translated his discomfort, and demanded the Angel to control her "concubine." White Chain promptly apologized and left with Allison in tow.[1]
Later, as the news of Allison's Key of Kings spread through the Glyphosphere, Nungsis gathered the forces of the Butchers' Guild and his peer Arat to demand Omun Vash to give up his prisoner to them.[2] In the subsequent standoff, Petal Knight 23 Liminal Blossom swiftly left him and the other contenders behind.[3]
He appears as a black hulking mass swathed in yellow robes clasped with a big silver brooch. His head sports horns, a small white Atum flame and four eyes around a golden tusked skull mask.[1]
