魔王によって衰退した人類の存続には勇者の血が必要と考え至った王国は、
勇者にたくさんの女性と子孫を残してもらい子孫繁栄を義務付けた。

城で働いていたメイドもその中にはおり、勇者とたびたび付き合いのあった
メイドの彼女も子孫繁栄の一助として駆り出されていた。
命令ではあったが、決して嫌だったわけではなく、むしろ最終的には自分から望んで
子孫繁栄を手伝ったとも言われている。

In order to secure the survival of humanity after going into decline due to the Demon Lord, the Kingdom came to the conclusion that the Hero's blood is necessary;
therefore, the Hero was ordered to perpetuate his descendants by having many women bear said descendants.

A maid that worked at the castle was among them; as this maid sometimes accompanied the hero, she was recruited to help with the task of perpetuating the Hero's descendants.
Despite being ordered to, she was in no way opposed to this; in fact, it is said that she herself actually desired to help with perpetuating his descendants until the very end.
