Jin wird von der ISDA verschleppt. Dort erfährt er, was es mit dem Shuttleunglück, bei dem er der einzige Überlebende war, auf sich hat.
Jin suddenly wakes up in an ISDA room, where he is questioned about the shuttle accident two years ago. He is also told the truth about the asteroid Thanatos, in which extraterrestrial life called Dragons came to Earth from Thanatos. Hearing that one of these dragons was the cause of the shuttle accident, he asks them to tell the truth to the public, so his father's name could be cleared. They deny his request and instead ask him to become a Dragonaut, which he rejects. He then meets Kazuki Tachibana, his old friend, who now works for the ISDA. Later, Jin remembers where Toa is to meet him, so he runs away from the ISDA to see her. The two are finally reunited, but it is cut short when the ISDA attempts to capture Toa. During their attempt, one of their own, Spirytus, transforms into a dragon and attacks Jin. In order to protect Jin, Toa reveals that she too can transform into a dragon.
