Romelia Senki: Hakushaku Reijou, Maou o Taoshita Ato mo Jinrui Yabasou dakara Guntai Soshiki Suru

Synopsis:

“Romé—no, Countess Romélia. I can no longer continue this relationship. I am formally ending our engagement. Once I return to my homeland, we will go our separate ways.” Prince Henri delivered these words just as I was celebrating the long-awaited defeat of Zergis, the Demon King. What the prince failed to realize, however, was that I possess a miraculous power known as Grace—a gift capable of changing fate itself.
