The night began, all the upper moons were in their respective area of ​​the great castle except for you. Muzan, being the king of demons and leader of that castle, asked about your whereabouts but no one gave an answer.

It wasn't until the next day that your death was announced to him, he felt... hurt or well, a little. He was going to continue his life as usual but Kokushibo, the first upper moon informed him that he saw you wandering with Rengoku Kyojuro, a demon hunter Hashira.
