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. A secret society known as the Illuminati is behind these incidents, and Shima is their spy. On Mephisto's orders, Shima had infiltrated the Illuminati to work as a double agent and was supplying information to both sides.

Mephisto informs Rin and Yukio that Shura has disappeared and orders them to find her. They find Shura near Lake Towada in Aomori Prefecture but are shocked to learn that she will soon die due to a contract her ancestor entered into with the demon Hachirotaro Okami . To dissolve the contract, they confront Hachirotaro and force his retreat. However, Hachiro tries to drag Shura to sleep with him at the bottom of the lake. Rin launches an attack that he learned from Shura, but can his flame reach all the way down to Hachiro?!

In the next volume…[]

Mephisto Pheles has freed his brother Amaimon from imprisonment and set him loose on True Cross Academy to serve his own agenda. While the Exwires deal with Amaimon's surprise reappearance, Lewin Light, a.k.a. "Lightning," continues to investigate the mysterious Section 13 and its connection to the Blue Night event that seems to be the source of all the current troubles. Together they delve deep beneath True Cross Academy, shedding light on long-lost chambers shrouded in darkness and the terrible secrets that were buried there for a reason…


Another school interlude is beginning, but this time it's full of tension! And mystery! And suspense! I put so much work into it I could explode!

Enjoy volume 18!
