Siblings that share the same body, they are Dicephalic Parapagus twins.

Shi is an expert hunter and being a wolf variation of a hellhound lets off a sulfuric musk while hunting. The eye on hir chest glows when hir heart rate picks up, as do the eyes on both heads. While they share the same heart and body, their separate minds can cause different responses to their body. They are aroused by different things and like different foods. The tail on the left side of the body responds to the more feminine heads reactions and the one on the right to the male's. Although they often bicker about prospective mates and or food items, they love each other dearly and do not tolerate anyone insulting the other.
