That demon looks like the nowhere king from centaur world ngl.
“Hush now, hide all you little ones. Rush, now, into the middle of nowhere, singing and laughter will die. Dreamless sleep follows the Nowhere King. When his kingdom comes, darkness is nigh. Quiet, crawl to the in between. Silent, secretive feeling of fearsome hatred that reaches the skies. You will bring joy to the Nowhere king, when he sees the light leaving your eyes.”
