Ao no Exorcist (Blue Exorcist) is a story set in the world where which consists of two different sides: Assiah, where humans live, and Gehenna, where demons live. The only way for these two worlds to connect is through possession.

The main character is Rin Okumura, the older twin brother of Yukio Okumura. He and his brother were adopted by the priest Shiro Fujimoto. He always took care of them and raised them as his own children. But, there were some things he kept secret from them. These were finally revealed when Rin suddenly gets ambushed by demons only to find out that he and his brother are the sons of Satan himself and that Shiro is an exorcist, which eventually leads to a fight between Rin and Shiro. Due to an insult from Rin directed to his adoptive father, Shiro's will weakened and he got possessed by Satan. The fact that his body was unable to contain all that demonic power causes Shiro a lot of damage, and Shiro, regaining consciousness for a moment, stabs himself and dies.

Trying to avenge his dead father and get rid of the demons, Rin opens the seal on Kurikara, a sword given to him by Shiro which contains Rin's sealed powers, and thus Rin awakens his demonic abilities and becomes a half-demon. Now, with the responsibility of defending Assiah and defeating Satan, Rin enrolls in the True Cross Academy in order to become an exorcist.

"I'm not your weapon; Demon King or savior! I'm Rin Okumura! And when I'm done, I'm going to be the best Exorcist you ever laid your eyes on!"

— Rin Okumura
