Meanwhile, at Cronos, Genzo is visited by inspector Lisker, who tells him that the headquarters are disappointed by his recent failures. Nevertheless, Genzo sends one of his best men to recollect Sho's unit, but with no luck.

Before leaving together with Tetsuro, Sho has a final encounter with Lisker in his Guyver II form.

Agito is still alive, and is now become the head of a group of rebels that try to steal from Cronos a mysterious chrysalis held by the organization in a research center located on the Dead Sea.

Thanks to his superior psychic abilities, dr. Balcus figures out the nature of the chrysalis and plans to make further studies on it.

Meanwhile, Aptom is visited by an old enemy seeking vengeance, and a very tough battle begins, with the entire city as a battlefield.

The chrysalis suddenly disappears from the Dead Sea research center, along with Guyver III, and reappears in Shinjuku, right in front of Zector, who's ready to finish Aptom off.

The Lost Number reveals to Tetsuro and the others that he watched over them for a year waiting for Guyver I's reappearance.

Both Aptom and Guyver III are beaten, and in the moment Zector is going to kill Agito the chrysalis finally opens.
