Mizuki Kibutsuji is the Demon Queen, the progenitor of all other demons in existence, and the leader of the Twelve Kizuki, an organization made up of the twelve strongest demons under his direct command. She plans to accomplish this in two ways: finding the Blue Spider Lily or creating more demons in hopes that one day, one of them will eventually be able to conquer her weakness of sunlight and absorbed them so she can achieve true immortality and eliminate her weakness to the sun.
