Blue Exorcist volume 6 features story and art by Kazue Kato.

The heads of the various Myodha temple families gather to discuss recent events surrounding the Eyes of the Impure King. Revelations at the meeting only deepen suspicion of Suguro's father, Tatsuma, and angry accusations follow. Tatsuma's silence on the matter isn't helping either. Amid all the swirling distrust, Rin tries to make sense of things but struggles to keep his flame in check. Then Rin receives a letter that may shed more light on the current situation - and the secret past!
