In Blue Exorcist, Vol. 6, Mamushi, a member of the Myodha sect, stole the right eye of the Impure King. Now chased by all exorcists, Mamushi finds Todo, who had taken the left eye of the Impure King, only to realize that Todo's plan is vastly different than hers. Instead of undermining the sect, Todo wishes to free the Impure King from his prison under the abandoned temple guarded by the sect. Betrayed, Mamushi escapes and manages to warn the exorcists about the coming catastrophe.

Meanwhile, Rin is still in prison, awaiting judgment and possible execution for defiling a direct order not to use his demonic powers. Reading through a letter sent to him by Tatsuma, head monk of the sect, Rin discovers valuable information about Father Fujimoto, the man who raised Rin and his brother Yukio, along with the role that Fujimoto played in acquiring the famous Koma sword. 

With the Impure King now on the loose, Rin is released by Shura, and is equipped with the Koma sword. However, it appears that he cannot pull it out of its scabbard. Has Rin lost his demonic abilities?

The story continues in Blue Exorcist, Vol. 8.
