Loran and the others encounter her and Quoatl, king of Adeska who says their people saw a vision of a nucelar blast. He agrees to help Loran after they fight and tells them of their legend of the Ades branch. Guin plans to fire the Willghem's mega beam cannon if Loran and the Suicide Squad can't take Manupichi by morning. Another Adeskan named Taruka confronts them, and everyone is thrown in a dungeon.

Joseph meets up with Mayalito who doesn't believe Quoatl to be a cowardly king. The Adeskans demand Quoatl pick up a sword and fight Taruka, but he refuses.
