Follow the X Spot Gun x Sword : Season 1 Episode 17

Van and Wendy are surprised to see The El Dorado Five at the rendezvous point, along with Carmen 99, Yukiko, Joshua, and Priscilla. After they all agree that they must stop The Claw, Carmen 99 sets up coordinates on the data disk in the hover-base, while getting money for supplies through a man named Manson. They are guided to a seaport kingdom near Missoghi controlled by its queen Catherine Nakata, where the initial plan is to capture her and sail through. However, they are invited to participate in a swimming challenge, to which they accept. Wendy faces off against Marianne to a race, and, with the help of Kameo, is able to reach the goal. Meanwhile, Manson explains to Joshua that he and the queen were once business partners in marriage, working together to develop an innovative metallic fiber. However, Manson had rejected her idea of creating underwear using the fiber, which had led her to build a bikini kingdom prospered by women. Fasalina is seen making a transaction with Catherine for materials called the "impregnable armor stock". After the race, Carmen 99 and Fasalina cause the kingdom to crumble from underground, as everyone evacuates. In the end, Manson reunites with Catherine after sporting her metallic underwear prototype.
