And has Mukohda finally found something worthwhile to spend all of his money on...? In time, circumstances allow Mukohda to set his sights on domestic life and building up his long-neglected business of selling Japanese goods. Unfortunately, his efforts land him in the sights of an unscrupulous competitor and a shady lesser noble, both of which have got their sights on the secrets behind his luxurious wares. Mukohda can’t rely on his familiars’ brute strength here, so he’ll have to fight fire with fire and play the game of politics himself! What will happen when otherworld magic and the marvels of modern product engineering collide?
