Ao no Exorcist: Kyoto Fujouou-hen

Rin Okumura's classmates now know the secret he desperately tried to hide: he is the son of Satan. Their fear and distrust leave Rin isolated just as a dangerous relic, the left eye of the Impure King, is stolen from True Cross Academy. When an attempt is made on the matching right eye in Kyoto, Rin and the other ExWires are sent to investigate.

The mission forces the group to work together despite the distance that has opened between them. Rin begins special training to control his blue flames, while old rivalries inside Kyoto's exorcist families and the possibility of a traitor threaten to awaken the Impure King. To protect his friends, Rin must prove that the power they fear can also be the power that saves them.
