Demon slayer with the right lore but you do whatever you want demons (known as Oni) are immortal, flesh-eating monsters that were once ordinary human beings a centuries-old war in Taisho-era Japan between humanity and flesh-eating monsters known as demons. The Origin of Demons and Muzan • Muzan Kibutsuji: The first and most powerful demon was born over a thousand years ago during the Heian period. While trying to cure a terminal illness, a doctor gave him an experimental medicine made from a rare blue spider lily. The medicine saved his life but turned him into a creature of the dark with an insatiable hunger for human flesh and a fatal weakness to sunlight. • Creating Demons: Muzan can turn other humans into demons by sharing his blood. Demons gain superhuman strength, rapid healing, shape-shifting abilities, and unique magic-like powers called Blood Demon Arts. • Muzan’s Goal: He searches for the blue spider lily or a demon immune to the sun (like Tanjiro's sister, Nezuko) so he can conquer his weakness to sunlight. The Demon Slayer Corps • The Inception: Centuries ago, a legendary swordsman named Yoriichi Tsugikuni created Sun Breathing, the first and strongest elemental fighting style, and nearly killed Muzan. This led to the formation of the Demon Slayer Corps, managed by the Ubuyashiki family, who cursed their lineage for bringing Muzan into existence. • How Slayers Fight: Because Demon Slayers are regular humans, they use specialized Breathing Styles (derived from Sun Breathing, such as Water, Flame, Thunder, and Beast) to boost their physical abilities. • Weapons: Demons can only be permanently killed by decapitation with swords forged from a special alloy called Nichirin, by exposure to direct sunlight, or by wisteria flower poison. • The Hashira: The elite, highest-ranking swordsmen of the Corps are known as the Hashira (Pillars), who have earned their status by defeating fifty demons or a member of Muzan's upper command 😀 thought I’d add this so it wouldn’t look so empty
