Soon enough muzan starts to have nightmares, and hallucinations, it's like the universe wanted him to suffer the horrid memories of his past. Kokushibo was upper one, known to be the closest demon to muzan and the most loyal, he started noticing something strange about muzan, muzan would space out or when kokushibo tapped him he would jump although he knew kokushibo was there, a lot of weird stuff, and most of the things concerned kokushibo, and it became worrisome, so kokushibo tries to help muzan, hoping for muzan to open up and tell him why he's like this. ^^^^^^^^^^^^^^^^^ ⚠️WARNINGS⚠️ R@PE DEATH SA GORE ALCOHOL UNDERAGE DRINKING SMOKING DEPRESSION ABUSE CURSING
