Blue Exorcist -Shimane Illuminati Saga-

The third season will focus on the enigmatic Illuminati society, who have ties to demons. The ultimate aim of this cheerful organization is to bring Satan back to life, but in the interim, they are experimenting on human zombies and creating an elixir that can bring demons back to life anywhere in the world. The strongest Demon is Lucifer, also known as the King of Light. Still, the abilities of a certain ExWire must be forced in order to create the ideal potion. At the conclusion of Ao no Exorcist Season 2, Rin's brother Yukio defeated the demonic Illuminati agent, while their member, the treacherous Saburota Todou, departed in an ashed form due to his regenerative powers. It's possible that Yukio received his powers from his father, Satan, but he kept this information from Rin and the ExWires.
