Death Devil

The Death Devil (の) is the devil that embodies the primal fear of death and a member of the Four Horsemen. It was mentioned by Makima, who sought to eradicate the other Horsemen, and later mentioned again by Hirofumi Yoshida. As death is the most fundamental fear living creatures can experience, it is presumably one of if not the strongest of all devils.

History
The Four Horsemen and the Weapon Devils once engaged in a brutal battle against Pochita in Hell. However, in the midst of the battle, Pochita mysteriously vanished. Despite searches by the Control Devil, Pochita could not be found. Unbeknownst to the Four Horsemen, this was because Pochita had changed forms on the verge of death and escaped to Earth.
