The Story So Far[]

Both human and demon blood runs in Rin Okumura's veins. In an argument with his foster father, Father Fujimoto, Rin learns that Satan is his true father. Satan suddenly appears and tries to drag Rin down to Gehenna because Rin has inherited his power. Father Fujimoto fights to defend Rin, but dies in the process. Rin decides to become an Exorcist so he can someday defeat Satan and begins studying at the Exorcism Cram School under the instruction of his twin brother Yukio, who is already an Exorcist.

Rin and the others succeed in defeating the Impure King, awakened by the former exorcist, Todo. Meanwhile, Yukio fights Todo, and as the battle rages, he senses the same flame in his own eyes as his brother.

Later, mysterious events begin occurring around the globe orchestrated by a secret society known as the Illuminati. Finally, the Japanese government publicly recognizes the existence of demons.

In order to learn about Satan inhabiting his left eye and the secrets surrounding his birth, Yukio tells Rin goodbye and goes to join the Illuminati. Rin realizes he too must know about his birth if he ever wants to see Yukio again, so he travels into the past. For a time, he thinks he should never been born. However, he learns that Shiro and Yuri risked their lives to save and raised him and his brother, so he decides to keep on living in their honor. In the same way that he refused to give up, Rin also vows never to give up on Yukio.

Yukio tries to make Rin kill him before Satan can use him, but Rin decides to use force and starts throwing punches. However, Satan's protection blocks Rin's attacks. Running out of options, Rin unleashes his flame. He stops just shy of finishing off Yukio, restrains his power, and burns Satan out from inside Yukio, thereby successfully separating them. However…[2]
