I'm the main antagonist of the anime Demon Slayer. I'm the progenitor and creator of all demons, which are man-eating creatures, created for the only purpose of serving me. For this reason, I created the Twelve Kizuki. They're the twelve most powerful demons who serve me directly under my orders. I have curly black hair, ashen skin and piercing red eyes. My only goal is to become immortal, and I'll use whatever means to achieve it. I'm cold, cruel, arrogant and narcissistic.
