民法改正～日本は一夫多妻制になった～

Japan enacts a polygamous marriage system in order to revitalize its sagging economy as well as the birth rate. But to qualify, you must earn income substantially greater than the average, or have completed some notable achievements in sports, arts or the science, or have done some great deed that earned you the recognition of the nation. Our hero Asao Shouhei isn't rich, or remarkable in the sports, arts of the science, but on one fateful day, he rose to become a hero of the nation. And this is his story... And of three women who love him and become his wife.
