As his dinner with Kusuzaki Zensuke and Kusuzaki Astrid is winding down, Ryūzaki Sanosuke sends out a request to his secretary Trivia. It only takes moments for her to follow up, giving Sanosuke reports of two sightings of a mysterious, white-masked merchant in Shimonoseki, the very town he's currently visiting. Excusing himself, he gathers his willing companions, Ryūzōji Ryouka, Takenaka Hanbei, Takayama Ukon, and Byakurei, and makes to leave the restaurant. He hasn't made it far, however, before Sanosuke is intercepted by Kono Mikono, who is understandably distressed that her customer is leaving both without paying and without providing the evening's entertainment he promised.
After dodging the proprietress, Sanosuke and his party regroup outside. Byakurei is sent to search the western parts of Shimonoseki where the merchant was seen last. Meanwhile, the rest of the group head east in the off chance that the lightning beast's search isn't successful. Before making it even a few blocks, however, Sanosuke is hailed by Byakurei, and told that the merchant is meeting with a woman wrapped in metal.
Upon arriving at the scene, Sanosuke finds the white-masked merchant unabashedly and aggressively peddling his wares outside a building of Alexandrian architecture. The only thing preventing him access is Blanca Garcés de Navarre, a woman from the Crown of Castille and geared in full, heavy, western armor. Sanosuke attempts to deflect the merchant from her, but the mechanical man is oddly insistent that not only should the weapons be sold to the representatives from Alexandria, but that they be loaded onto their ships and taken back to their homeland.
Eventually, with the surprising and timely appearance of Hashinara Yoshitakatomo, Sanosuke is able to convince the merchant that the Hashinara will handle movement of his wares onto the Alexandrian ships. Satisfied with this answer for now, the merchant departs, and Yoshitakatomo follows him, cloaked in a spell of undetectability.
With those two gone, Sanosuke engages Blanca, Countess of Navarre in discussion about their respective lands. She is amiable enough once it becomes clear that Sanosuke is not seeking an audience with Phaenarete or trying to sell her anything. Indeed, Blanca eagerly falls into the role of teacher at Sanosuke's request, telling him much about the Alexandrian Dominance, Megas Alexandria, and the main forces that make up the Empire. Namely, Blanca's own Crown of Castille, The Enlightened Republic of France with its Twin Queens, Gewehrland with its advanced weaponry, and Mavrovlachia with its bloody devils and universal prisons.
Sansouke listens politely, and Ukon seems unhealthily interested in the subject of prisons. Eventually, his group departs and they head back to The Tanuki's Glee. On the way there, the clattering of a cart is heard once again. After consulting with Yoshitakatomo, Sanosuke instructs Shigeaki Fujino to steal the cart of weapons away from the hapless mechanical merchant, then resumes his return to the restaurant.
