A SALES PITCH FIT FOR ROYALTY

As a visitor to the royal court of the Twin Kingdoms, Zenjiro swiftly got caught up in the intrigue of a royal succession. Not all is as it seems, and even innocent gestures carry hidden meanings. To survive the dangers, Zenjiro has no choice but to design a brand-new magical item that will amaze the rich and powerful of this foreign realm.

Any mistakes here could ripple all the way back home to Capua and change the fate of his whole family. It's time for Zenjiro to dust off his long-dormant skills in business and make a sales pitch fit for a king!
