In order to protect his friends, Yamaguchi accepted a proposal from the tyrant price, Daishou. Something is wrong in the Slithering Isles, though, and war seems imminent. Yamaguchi sets out alone to try and prevent disaster, but to what ends is he willing to go? Meanwhile, Tsukishima receives a mysterious letter stating that Yamaguchi, and the continent as a whole, are in grave danger. The Nekarasi crew gets back together to save their friend from an untimely demise. Their journies dig up uncomfortable pasts, bring to light new corruption, and, against all odds, draw Yamaguchi and Tsukishima ever closer together. -This is a sequel to my other story Mark of the Firefly, it will not make sense if you don't read that first, just a heads up.-

Nothing much of interest ever happens in Yamaguchi's little scrap town on the outskirts of the habitable continent. Just scavenging and sales. So, when his long-time friend, Kageyama, bursts through Yamaguchi's door in a panic brandishing a magnificent object branded with the Mark of the Firefly, a wealthy neighboring empire, he doesn't have much of a choice but to leave town. Breaking onto a continental freight train, getting caught and rescued multiple times, and becoming one of the main players in a continent-wide game of espionage and royalty was not exactly on Yamaguchi's to-do list, but what other choice does he have?
