Sakahagi is an original design and demon to Shin Megami Tensei III: Nocturne, being an evil Manikin. The name Sakahagi comes from a Japanese execution technique where the victim's skin is torn off of their body entirely, alluding to Sakahagi's design.
Design
Sakahagi's garb is made up of the skins of other Manikin, and he wears a mask of another's face. He also sports a rope around his waist, and sandals made of smaller ropes, just as the typical Manikin do. his sleeves, the only part of his clothing aside from his cut-down unamori is splattered with blood.
The imagery of a body covered with faces is reminiscent of the Pseudo-Fiend.
An evil Manikin that was reborn, called back into the world by the Afterlife Bell. Because of his doings in the previous life, he has gained new powers.
