Orthodox Hero

Demon King Finette was minding her own business at home, reading manga and listening to music, when the Hero came and beat her up. After spending two lifetimes as a good-for-nothing shut-in, Finette has never practiced swordsmanship or studied magic for even a single day since taking the throne. There's no way she can beat the Hero in a fight. If she can't fight back and can't run away, then all she can do is…sell herself, right?
