Fight hellfire with hellfire!

''The operation against Professor Gedoin's diabolical Dream Town Inari is just the opening round in the growing conflict between the Knights of the True Cross and the Illuminati. As both sides regroup and lay plans for the future, the Exwires try to come to terms with what has happened. Though Izumo finds some peace and a new sense of purpose, serious questions about Renzo Shima's betrayal still need to be answered. It's not an easy thing for Rin and his friends to learn that they have become pawns in Mephisto's schemes, but the game is on!''

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 incidents, and Shima is their spy.''

''When the Illuminati kidnaps Izumo for experiments, Rin and his friends head for Inari, in Shimane Prefecture, to rescue her. They find Izumo within a research facility, but Shima blocks the way. When Izumo becomes host to Nine Tails, Izumo's mother Tamamo , whom Izumo has hated for a long time, saves her.''

''When Izumo sees her mother risk her life for her, she recognizes that the way she has been living was mistaken and decided to start trusting other people. In order to cleanse her past, she uses the Repose Spirit Incantation to exorcise Gedōin, the source of all the trouble!!''

In the next volume…
''The surge of demonic activity around the world has the Knights of the True Cross worried at the highest levels. An important meeting at the Vatican will have serious effects on the lives of Rin and his Exwire friends. Back at True Cross Academy, the students get a sense that something is brewing with the arrival of an unexpected and definitely unconventional new instructor! Meanwhile, Yukio struggles to understand the strange fire in his eyes, a fire he has kept secret from everyone. Can he confront the flames inside him alone, or will they consume him?''
