Argument
The world of Ao no Exorcist is composed of two dimensions united in one like a mirror. The first world is that of humans, Assiah, the second is that of demons, Gehenna. As a rule, travel and contacts between the two worlds are impossible, but demons can go to the human world and possess everything that composes it. Satan, the demon god, tried to enter the human world, however he was unable to do so since there is no body in Assiah strong enough to hold his immeasurable power. In this way, he met a human woman whom he could possess, and thus fathered two twin sons with it, which were called Rin and Yukio Okumura.

The story revolves around Rin Okumura, who is a teenager who possesses a unique strength and endurance and who was raised along with his younger brother, Yukio, by the priest Shiro Fujimoto.

Shortly before Yukio left to study at the prestigious Vera Cruz Academy, Rin discovers that he and his brother are children of  'Satan' , the most powerful of the demons, and after witnessing how his protector, the priest Fujimoto, dies to save him and prevent his father from taking him to hell, Rin ends up doing what his guardian asked him never to do, unsheathing the Kurikara sword, since it contained his demonic powers.

Anyway Rin refuses to follow the plans of his father and enrolls in the Vera Cruz Academy to become an exorcist and thus be able to avenge the death of Fujimoto, whom he considers his only father, destroying Satan. From the moment he takes possession of the sword, Rin acquires permanent demonic characteristics such as fangs, a tail and the power to produce the destructive blue flames characteristic of Satan himself.
