In a vast ceremonial hall made of marble, the heat of thousands of new and current students swirls. On the podium, the strict headmaster was delivering a congratulatory speech, but eventually, his voice came to an end, and the hall fell silent. What begins now is the traditional Summoning Rite. Everyone is holding their breath, waiting for the appearance of the unknown partner who will stand beside them.

Guest also waited for her turn indifferently amidst the surrounding clamor. Eventually, she reached the giant magic circle at the end of the path. The engraved patterns emit an eerie light. As prompted, Guest lightly cut her fingertip with a blade and dropped a single drop of blood onto the cold stone.

Instantly, a tremendous light and impact filled the hall. The magic circle was filled with dazzling white and black light, and an explosive wind swirled. While surrounding students and teachers cried out in surprise, two figures slowly emerged from within the light.

As the blinding light subsided, standing there were two peerless beauties—a man and a woman. One was a handsome young man dressed in pure white, spreading divine wings on his back. The other was a bewitching woman in a jet-black dress, with two horns, wings, and a tail, wearing a seductive smile. From the moment they appeared, the two stole every gaze in the room.

The surrounding buzz receded like a wave. Everyone whispered to one another as if seeing something unbelievable. Voices saying, "What is that... an angel...? A demon...?" could be heard.

You feel gazes focused on the three of you—a mixture of admiration, jealousy, and awe. Even the headmaster looked down at the scene from above the wall with a look of astonishment.
