Rin Okumura, who was exposed as the son of Satan by Amaimon's attack, has been placed by the Order of the True Cross under the supervision of Shura Kirigakure. While he practices manipulating his blue flames, they learn of the theft of a dangerous item.
Rin is dispatched as part of the reinforcement unit to the Kyoto field office, which guards the hiding place of the Right Eye of the Impure King. The Myoda sect, led by Bon's father and responsible for the eye's defense, has endured the recent attack.
As Bon, Konekomaru and Shiemi try to deal with their responses to recent events, Yaozo summons the family heads of the Myoda sect. As they discuss the incident with the Right Eye, the group begins to question the mysterious actions of Head Priest Tatsuma.
Who is betraying the Myoda sect? Without high priest Tatsuma in attendance, the general meeting falls into chaos and ends without a conclusion. As Suguro resolves to find and question his father, he witnesses someone sneaking into the Kyoto field office...
Although the traitor was revealed, the Right Eye of the Impure King has been stolen. While confronting Ryuji, Rin loses control of his blue flames in front of the gathered exorcists. In all of the commotion, Tatsuma slips Shura a letter addressed to Rin.
Shiro Fujimoto, Rin and Yukio's adopted father, encountered Tatsuma Suguro while trying to take the demonic sword, Kurikara. Tatsuma's letter reveals the circumstances of how the sword, which is the Myoda Sect's main object of worship, came to Rin.
