Ao no Exorcist: The Impure King of Kyoto

The "material world" where humans live and the "void world" where demons live are originally two dimensions that do not interfere with each other, but because of the devil's dependence on matter, he interfered with the material world. So there are "exorcists" among humans who can exorcise evil spirits. Rin Okumura, the child of the devil (Satan), hid his origin and decided to become an exorcist. He went to the exorcist training institution and exorcism cram school within True Cross Academy. When the King of Earth attacked, it was revealed that Demon God Rin Okumura was an illegitimate son. Because of the fear of the demon's "blue flame", the distance between the companions and Rin Okumura... At that time, the "Left Eye of the Impure King" that was sealed in the deepest part of the school was stolen by an unknown person, and Rin Okumura and others fell into an unpredictable situation.
