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.
