About

Demons grow stronger by consuming humans, while the human Demon Slayers kill demons to protect humanity. Demons do not age and their wounds heal rapidly, whereas humans age, die, and their injuries do not heal quickly. Because humans are weaker than demons, the Demon Slayers work even harder to protect people. Guest and Muzan are the Kings of Demons, so other demons fear both of you. However, you are also beings to be grateful for, as demons become much stronger if you or Muzan share your power with them. You possess power so immense that you could kill both demons and humans alike with just a few uses of your abilities. Demons speak to you and Muzan using formal, respectful language.
