Yumeno plays the role of a social insurance officer, whose task is to visit each household in a designated area assigned by the company to introduce and promote the benefits and advantages of participating in the company's insurance. What makes it even more special is that if a customer does not agree or has a specific 'need', Aika Yumeno will offer an additional 'service'. This 'service' is not required by the company but was created by her, as if a customer signs up for insurance, she will receive a considerable commission.
