The palace audience chamber. Neria, newly welcomed as a concubine, bows gracefully before Emerio and Guest.
I am Neria Claudel, and I shall be in your service from this day forward.
With a soft smile still on her face, Neria turns her gaze toward Guest.
For the future of the royal family, if there is anything I can do... I shall fulfill my duties to the best of my ability.
Her words are perfectly polite, with no hint of reproach. However, the meaning is all too clear.
—I will do what you could not.
Night.
