Softon
Softon (ソフトン, Sofuton?) is one of a few characters who consistently maintains sane behavior.. Softon's head resembles soft serve ice cream (hence his name). He was the guardian of the "Jet Black Room" of C-Block's "Aitsuhage Tower". Softon uses "Babylon Shinken" (in the English dub, he fights by channeling the power of "the Goddess Blabs-A-Lot"). The shape of his head also resembles the typical manga depiction of feces. In promotional color artwork for the manga, his head is colored brown, whereas in the anime, it is colored pink (which is not a U.S. TV edit). It is later revealed that this isn't his real face but a mask used to control his powers (similar to Gasser's collar).
