Enmu Enmu
One of the Twelve Kizuki, who are under Muzan Kibutsuji's command. He takes a twisted delight in observing the agony and despair of others. During the purge of the Lower Ranks, he gained favor with Muzan Kibutsuji, and so wound up being the sole survivor.

He is ranked Lower One, higher than Rui (Lower Five), the demon who had so overpowered Tanjiro and the others on Mount Natagumo, and has been given a share of Muzan Kibutsuji's blood.
