In order to build a prosperous future for Listill's village, Lutz, Claudia, and Ricardo set out for the federation. With the help of Gwynn, they try to convince the many tribes of the federation to be open to international trade, but they face several roadblocks along the way. One thing is for sure: When it comes to intertribal relationships, nothing is as simple as it seems. The old, stubborn chiefs fatten themselves while their people starve, but one young woman decides that it is time for change. She challenges the chief of the village, her own father, to a duel. The chief wields an ancient and mysterious enchanted sword, and the young woman must find a weapon that matches her father's power. While Ricardo is as enamored with Tsubaki as ever, he senses that something is missing. Due to the potency of Tsubaki's curse, he has been using a normal sword as his main weapon. Is such a state of affairs acceptable, or could it be time to find Tsubaki a sister?
