"Please take him back, I don't want any sacrifice" Nanao, who was born into a prestigious family, was raised to be a sacrifice. In the 111th year, when the day of contract renewal arrived, Nanao visited the great serpent to offer himself as an offering and to be eaten. However, the great serpent is so immersed in the daily, slow life of humans that he allows Nanao to pay him in advance by saying "I DON'T NEED ANY SACRIFICE" (Source: Libre, translated)
