Reunion with childhood friend Naida. It brings a brief moment of peace to Duke. However, she approached Duke as an enemy of her brother Sirius. The blade of love and hate is approaching.

Duke's anger burns up in the despicable cassado. He makes Grendizer run wild, but he remembers his promise to Koji and stops. Duke regrets that he got on again and cheers of gratitude.

Duke defeats the Vega forces, but loses his senses and flies away eventually landing on Ogami Island. Koji follows him and just as he meets the island's shrine maiden Hikaru, his arch enemy Cassado attacks Earth.
