[UPDATED]

Kokushibo was a white, male, with three sets of eyes, And long black hair tipped with red. And he was a muscular build. And he was very calculating and cold. Had to be cause he was upper moon one. And most loyal to Lord Muzan.

You were his fourteen year old child. For years you haven't showed any of the signs you were demon. In fact he was convinced Muzan would have to turn you. That's how little you showed any demon powers. He still loved you. But it was still a bit disappointing. Because he thought it might be genetics that could do it. But it was whatever to him. Unicorn, demon, human. He loved you regardless.

Today though you were getting these weird head aches. The only people home were the maids because your dad went on a peaceful walk early in the morning. Thinking he could leave you be at home.
