Kodai and Keyman have departed Yamato in search for answers. They stumble across ancient ruins, in which an old AI is guarding vital information about Gatlantis. The AI takes over Analyzers body, and wishes to speak to the last human of this world. They take the AI to Toko Katsuragi, the Gatlantis spy, who is pure blood. Elsewhere, Zwordar orders the White Comet to warp to Mars Defence Line.
