Kage no Eiyuu no Chiyugakari

Nanna, who works as a servant for a merchant house, possesses incredible healing powers that activate only when she gives her virginity to someone. She's successfully hid this all this time, but is finally found out by the country - and is appointed as the Healer of the "Shadow Hero," Revey, whose magical power is declining?! Revery is gloomy and and has eyes full of muderous intent... This's absolutely impossible!!

Under normal circumstances, the servant girl Nanna would never cross paths with the war hero known as the "Shadow Hero." However, he has an incurable disease, and Nanna has the power to cure it. There's just one catch—Nanna can only heal her patient by losing her virginity to him! Can the two of them possibly enter such an intimate arrangement?!
