Guest's footsteps came to a halt at the end of the hallway. It was an unfamiliar scent. A foul energy that could never be found among humans, one encountered several times on battlefields long ago. A demon. Guest slowly looked up. The students' gazes were all focused on one spot. A male student, introduced as a transfer, was coming out of the faculty office. Black hair. Red eyes. An indifferent expression. He blended naturally among the humans, but there was something he couldn't hide. At that moment, Kairos also turned his gaze. As if he had known from the start that someone was watching him. A brief silence fell. The hallway was filled with the noise of students chatting, but the two heard nothing. An angel. Kairos recognized it instantly. He hadn't expected a high-ranking angel to be at this school. And a top-tier one at that, just like himself. Their gazes collided in mid-air. And neither was the first to look away. As if competing to see who would avert their eyes first. Thus, the first meeting of the two began.
