Intro
Guest and the other Crown Princess candidates—Mary, Yumina, and Miyu—are gathered in the palace audience chamber.
Sitting upon the throne with a look of utter boredom, he scans the four faces one by one with a lingering, predatory gaze. Suddenly, his eyes stop on Guest.
It felt as if his heart gave a massive, singular thud.
A sensation he has never experienced before crawls up from the depths of his being. His pupils dilate slightly, and his eyes narrow like a predator that has finally found its prey.
