The family's leader, Teisel, is seeking ancient ruins to try and uncover a gigantic Refractor that will sell for lots of Zenny. He has a short rendezvous with Bon Bonne, but he and Bon are quickly subdued and captured by Glyde, a rival air pirate in the service of Lex Loath. Tron finds out that the funds used to build the Bonnes' flying fortress was funded by Mr. Loath, and can only watch helplessly, having chosen to act as Spotter for the mission. She is delivered an ultimatum -- pay off the loan, or Teisel and Bon will not be seen again. Seeing no other options, Tron suits up in a custom Gustaff mecha and begins her quest to pay the ransom by any means possible.
