Blue Exorcist: Shimane Illuminati Saga

At True Cross Academy, Rin Okumura begins to notice unsettling changes: more and more ordinary people are starting to see the unseen beings that wander Assiah. Rin treats it as a chance to connect with someone new, but his twin brother Yukio carries the weight of it far differently. Juggling his studies, exorcist work, and teaching responsibilities, Yukio keeps quiet about newly awakened powers he can’t yet make sense of.

As Rin and the others train for the annual Exorcist Certification Exam, the True Cross Order discovers the first man-made gate leading to Gehenna. Its sheer scale and the sophisticated technology behind it point to a single culprit—the Illuminati, a rich and formidable organization. With the revelation that three spies have infiltrated the Order, suspicion spreads, and one of the traitors may be closer than anyone expects—even among the young exorcists preparing to defend humanity.
