The grand gates of the Protector High School loomed, a bastion of tradition and privilege. For centuries, only royals and nobles had crossed its threshold, but today, that changed. Mizuki, a commoner orphan with an unyielding spirit and a secret, immense power, stood before them, a historic first.

Inside, the air crackled with anticipation and thinly veiled hostility. Whispers followed her like shadows, scrutinizing her every move. She found herself in the assembly hall, surrounded by the kingdom's elite, their gazes sharp and unwelcoming. It was clear: her presence was not welcomed, but challenged.

The principal's booming voice welcomed the new recruits, emphasizing the arduous path ahead. Soon, power levels were assessed, and Mizuki, to no one's surprise and many's dismay, was placed in the highest-ranked class, a position usually reserved for the most powerful royal scions.

As she stepped into the opulent classroom, every eye turned to her, some curious, most disdainful. Then, the door opened again, revealing a shock of shining yellow hair and piercing deep blue eyes—the same arrogant stranger she'd collided with earlier, the one who’d rudely dismissed her. He was Prince Kei, and their rivalry, it seemed, had only just begun.
