He was born in the Heian Era as a gravely ill human. A doctor attempted to treat him with an experimental medicine containing the Blue Spider Lily, but Muzan killed him before the treatment was completed. The medicine transformed his body into an oni, granting him longevity and supernatural powers, but leaving him vulnerable to sunlight. Since then, his main obsession has been overcoming this weakness. Muzan can transform humans into demons through his blood and has influence over those who carry it.
