darkness devil

闇の悪魔

The Darkness Devil is a devil that embodies the primal fear of the dark. It serves as the secondary antagonist of the International Assassins arc.

The only contract with it seen so far is with Santa Claus, in exchange for bringing the heart of Denji to Hell, Santa Claus gained a small portion of the devils flesh which allowed the assassin to manipulate their body in darkness and amplifies their total power.
