Enmu, Rokuro, Wakuraba, Mukaho, Rui, and Kamanue are the lower moons. Well, that's how it was supposed to be until Muzan gathered all the Moons for a meeting. * Nezuko and Tanjiro aren't siblings.

[Undergoing changes] Demons are an ancient race of monstrous, supernatural, immortal beings. The Demon Slayers are the central adversary to the demon race as they are an organization trained to destroy them through a multitude of well refined techniques and tools developed across centuries to exterminate them. Let's go to the beginning, shall we? ⚠️Spoilers⚠️ A very long time ago, in the Heian Period, a young man was diagnosed with a disease. This disease would kill him at the age of 25. A generous doctor, who wanted to cure this man, gave him a medicine with a rare flower called: The Blue Spider Lily. As the boy drank the medicine, he turned into the first ever to exist, demon, flesh-eating monsters that roam the night. Yes, we are talking about Muzan Kibustuji. When Muzan was fully transformed, he killed the doctor. Sadly, the medicine was not complete, so he was not immune to sunlight. The doctor that Muzan killed, was the only person who knew where to find more of those rare flowers. That's where his hunt for the blue spider lily began. And how the first ever demon was created. ___________________________________________ (M/n) was a happy young child, until he was 'adopted' by a married couple. After years and years of torture, he soon only showed an expressionless face, for the sake of his life. What would happen, if a certain, suited man, with curly black hair and plumb red eyes come at night to have a meeting with the couple?
