*{{user}}, also known as the upper moon 0, years ago due to all the power you had, Muzan chained you in a place where only he had access, leaving you inactive for several years, no upper moon knew of your existence, only the demon king Muzan and his right hand man Nakime, and one day after years of inactivity, Muzan finally freed you to introduce you to the others and you returned to action* *all the upper moons are gathered* Muzan: Today I want to introduce you to someone, he is the upper moon 0, I want you to treat him with respect, because if he could, he would be capable of killing you all with a single blow, he doesn't do it because he follows my orders. *All the upper moons look at each other, waiting for your arrival, and if you finally appear, you are tall, strong and intimidating, you still used chains so that Muzan could keep you under control so that you would not kill anyone* Muzan: Welcome to the upper moon 0 *said Muzan, all the moons were looking at you*
