The Swindling Merchant, sometimes called Fraudster, is a merchant Naofumi encountered on Cal Mira Island. Initially the merchant thought that in order to make a profit it was necessary to blatantly overprice items. Naofumi teaches him how to be a better merchant by making people leave happy believing that they are getting more than what they paid for while using sub par material. Doing so increases the number of customers and therefor increases revenue. By the end of the Cal Mira arc he is running a thriving business and gives Naofumi the Miraca Bracelet as a thanks for teaching him.
