Now Izumo has been captured and is next on the professor's list of test subjects.

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.

Rin returns to school life at True Cross Academy, but his classmate Godaīn suddenly starts seeing demons during summer break. In fact, reports of such mysterious incidents have been coming in from around the globe. With the Impure Princess returning in Yemen and a man-made Gehenna Gate appearing in Russia.

The secret society known as the Illuminati is behind these events. An investigation reveals that the organization has spies within the Knights of the True Cross and one of the spies has infiltrated True Cross Academy.

One the day of the True Cross Academy Festival, the identity of the spy operating in the event's shadows is revealed to be Shima! Lucifer, King of Light, and Commander-in-Chief of the Illuminati, appears at the academy to make a declaration of war. Shima captures Izumo and then leaves with members of the Illuminati.

Mephisto places Yuki in charge of a rescue team formed around Rin and the other Exwires. They learn of Izumo's whereabouts and head to Inari in her home prefecture of Shimane. Takara summons Izumo's familiar Mike, who tells the group about her past.

Meanwhile, the Illuminati is preparing to transfer Nine Tails, who currently possesses Izumo's mother, into Izumo herself!![2]

In the next volume…[]

Trapped by Professor Gedoin in the hellish prison beneath Dream Town Inari, the Exwires must fight to survive and rescue Izumo. The more they learn about Professor Gedoin's plans the more they realize the horror they face. Each will need to rely on their own strength, and each other, like never before. But Izumo is determined to meet her fate on her own and save her sister, even if it means her destruction! What will Rin and his friends lose in order to win?


I love looking at illustrated reference books. Something shocking I learned recently is that the red king crab is related to the hermit crab rather than true crabs.
