This section, or a part of it, has been transcluded from Volume 22; any changes involving it should be made there instead. / 

The tragic story of what happened to Rin and Yukio's mother, Yuri Egin, continues to unfold. Yuri and Father Fujimoto were once up-and-coming young Exorcists involved in Section 13's extensive operation to research elixirs of immortality and develop clones to house the spirits of demons. The project seemed to be moving ahead until the unexpected manifestation of a demonic spirit into one of the clone bodies. And not just any demon—[3]

The Story So Far[]

Unknown to Rin Okumura, both human and demon blood runs in his 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. Afraid, he keeps it a secret.

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 asks Mephisto about it and receives a key for traveling into the past. Rin goes back in time and follows Shiro and Yuri in their youth and learns that their fates are harsher than he ever imagined.

The moment when Satan will take corporeal form is approaching![2]

In the next volume…[]

Rin's journey to the past takes him to the fateful night of his and Yukio's birth. The Knights of the True Cross prepare powerful barrier spells and sutras to deal with what is coming, but no one is really ready for what is about to happen. Back in the present, Yukio begins to come to terms with his inner flame and Lucifer bestows a gift on him. Elsewhere, Suguro and Kamiki come to a shocking realization about Shiemi, and the threads of Mephisto's web of schemes tighten even more…
