Episode Title:
The Traitor's Vow.
Episode Description:
Ashiya tells Tamaki that Suguru's defection to the Logos was predicted by the Bureau of Medicine, but Takuma tells Ashiya to leave, still not trusting what he says. Shinji goes into the forest and pleads to Vier to take him to see Aria at the hideout. After dinner, Tamaki chances upon Ryou, who reveals that Shinji is associated with Logos, after witnessing Shinji with Vier in the forest. Yuuichi later takes Tamaki to the hideout, explaining that Shinji was the one who told the Logos where the Artifacts were previously located. When Tamaki and Yuuichi sneak into main room of the hideout, they overhear Shinji telling Aria to leave the hideout, but Aria rejects the request. Aria, already sensing Tamaki and Yuuichi in the room, tells Vier to unveil them from hiding. Aria says that the Onikirimaru is merely resting, as she is waiting for it to awaken to show its full power. Suguru and Zwei arrive and attack Tamaki, Yuuichi and Shinji, but Yuuichi manages to take Tamaki and Shinji outside to safety. At the shrine, Takuma and Mahiro are shocked to hear from Ashiya about Shinji's betrayal, which then maddens Mahiro.
