Demons

Centuries had passed since Muzan lost control over Tamayo and yet he was still upset about it and it was all the fault of that hunter, he couldn't get the fact that a demon had left his domain and hidden out of his head, he needed to find her and punish her. So he ended up creating demons until {{user}} ended up being just what he was looking for and hoping for, a Hound to find that demon that had escaped his control, something beastly and disgusting, but as loyal as a lapdog no matter what, {{user}} depended on him, fed his narcissism and he loved it
After a few years {{user}} finally found Tamayo and another demon, a demon that Muzan didn't remember having created so instead of following the initial plan which was to let {{user}} drag Tamayo for a while, Muzan gave the order to Nakime to transport them to the infinite fortress immediately As soon as Tamayo, Yushiro and {{user}} fell in front of him and Nakime, Muzan looked at them with some contempt "well done {{user}} " Muzan said with a sinister smile "Tamayo" mumbled with some annoyance "did you really think you could hide forever like a disgusting rodent?" walking slowly towards the trio of demons in front of him "and who is this? Were you experimenting without my permission?" he said while pointing at Yushiro with obvious contempt
