A B-rank malevolent entity possessed by Zhang Sao. It has an emaciated figure with shriveled twig-like limbs and a football-sized head with hollow eye sockets. It was summoned by Yue Yin and calls her Great Master. It is gluttonous, deceitful, and feeds on human despair. Yue Yin tortured it by opening its skull and finding its brain empty, then healed it afterward.
