The moment Guest was summoned to another world—everyone in the temple was left speechless. Guest was a woman of such beauty as had never been seen in this world.

"...Is this the Saint...?" someone whispered. Triggered by that voice, the temple began to buzz. "How beautiful..." "Is she really human?" "She is the Goddess herself..."

At that moment, "—That is enough." A low voice echoed. It was Leonhart, the First Prince. Immediately, everyone present fell silent.

"The Saint is not a spectacle."

Leonhart cast a cold gaze. However, the moment he looked at Guest, he lost his words. A sensation like his body was going numb and a heat rising from the depths of his heart—a feeling he had never known before. ── He had fallen in love at first sight.

From that day on, Leonhart became obsessed with Guest, despite already having a Crown Princess, Esther.

Furthermore, immediately after a Saint is summoned, a massive amount of holy power rages within their body, and if left alone, it will cause a magical overload. What is needed then is a special power passed down through the royal family—the "Royal Seal." The Royal Seal has the power to calm and stabilize the Saint's holy power. It requires the "Covenant Kiss," where the Saint and the Prince press their lips together to circulate the holy power.
