Be it forte or skill, the wizard Elena's capabilities are all top-notch. However, even Elena has a few flaws—her poverty and immense debt!! And the most devastating of her flaws is the fact that jewels are her medium for magic. Then, one day, she is recruited by the greatest household in the Borina Empire, the Mayfield Duchy, as an exclusively contracted wizard. At the thought of being able to pay back all her debts at once, Elena accepts the offer. However, protecting the duchy, which stands at odds with the empress, is harder than expected. To make things worse, the duke of Mayfield, Cedric, who thinks of wizards as less than bugs, is turning out to be an obstacle for Elena. Will the opportunistic wizard Elena be able to safely complete her task? (Source: Kakao Entertainment Corp., translated)
