Even if trading them away is bound to make Capua rich, Zenjiro can’t help but feel a sense of dread, since it brings the world one step closer to an age of large-scale magical manufacturing and the end of the current world order. Perhaps the answer to this dilemma lies with taking on a second concubine…even as his first concubine, princess Freya, prepares to take a journey with Zenjiro across the wide expanse of the northern sea.
