Episodes

After his secret is exposed, Rin takes part in a special mission along Shura and Yukio to retrieve the "Left Eye of the Impure King", a demon relic that was stolen from the True Cross Academy's vault. In the occasion, they fail to retrieve it, but discover that the culprit is Saburota Todo, one of the exorcists in charge of the vault that was corrupted upon being possessed by a demon. After hearing that there was an attempt to steal the Left Eye's sister relic, the "Right Eye of the Impure King" in Kyoto, the Order sends a team there to investigate, including Shura, Yukio and the Exwires, who are in conflict after learning the truth about Rin.

The Exwires arrive at Kyoto, and Ryuji, Konekomaru and Renzo take the opportunity to reunite with their families, while Rin and the others tend to the Exorcists of the Myoda Sect, who got wounded guarding the Right Eye of the Impure King. In the occasion, Rin meets Ryuji's father, and learns that Ryuji is resentful of him, as despite being the leader of the Myoda Sect, he is not respected by the others, as he relegated his duties since the Sect, which was weakened after losing several of its members on the Blue Night, joined the True Cross Order. Meanwhile, Todo, with the Left Eye of the Impure King replacing his own, contacts his mole inside the Sect, planning another attempt to steal the Right Eye.

The Myoda Sect has an emergency meeting to discuss the failed attempt to steal the Right Eye of the Impure King and discover who among them is the traitor collaborating with Todo. In the occasion, suspicions were raised towards two of the sect's exorcists, Renzo's older brother Juzo and Mamushi as they were present at the scene and were Todo's students in the past, but the head priest, who did not attend the meeting, was counted as a suspect as well, much to Ryuji's anger. Meanwhile, Rin continues with his training to control his flames while trying to reconcile with his friends, who fear how the Myoda will respond once they learn that he is the son of Satan.

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.

The Impure King has been revived! In his letter, Tatsuma asks Rin to use the Koma sword to fight, but will that even be possible? And to make matters worse, Mephisto suddenly appears with the news that Rin has been sentenced to death!

Miasma spreads through the streets as the exorcists begin to counter the Impure King’s growth. Rin leaves with the other students to find Tatsuma. Yukio is on the front lines, unaware his brother has left his cell, when he notices something strange…

“You despise your brother, don’t you?” Yukio is shaken as Todo tells him to admit his true feelings. Yukio reflects on the thoughts he’s had since an early age. Meanwhile, Suguro has inherited the Gouha-en, and with it, he and Rin head to the sporangium.

The sporangium has finally burst, revealing the Impure King. Assaulted by the miasma, Suguro barely maintains the barrier. And every passing moment brings him closer to his limit. Rin questions why he can’t draw his sword, even when backed into a corner.

Rin finally manages to draw the demon sword. Shura tells him to, “Win a place for yourself in this world!” However, there doesn’t seem to be a way to stop the Impure King’s overwhelming growth. And if Suguro’s strength fails, the barrier will collapse!

The sight of a blue flame burning in the night sky is reminiscent of “Blue Night,” but has brought about a completely different result. Now that the incidents relating to the Impure King have been concluded, those affected are moving on.
