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.

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.

As he observes the lives of Shiro and Yuri, Satan takes a corporeal form. Yuri keeps Satan company to prevent him from raging out of control, and he gradually falls in love with her.

They try escape Asylum to live a quiet life, but the Order captures them. Then Shiro learns the shocking fact that Yuri is pregnant with Satan's child!![2]

In the next volume…[]

The Blue Night has begun and Satan's cloned body can no longer contain the massive cosmic energies within him. The Knights of the True Cross are faced with an unprecedented crisis as a wave of destruction begins to sweep across the world. While the Knights resort to extreme measures in an attempt to restrain the newborn Rin, Yuri Egin continues to struggle with childbirth—Yukio is about to enter the world as well. The blue flames continue to spread and no one will be spared their heat…
