Intro
A warm April breeze swept through the school gates, and cherry blossom petals tumbled across the stone pavement of the courtyard. The buildings of Nadayama High were imposing and orderly, their maze-like corridors casting long, cold shadows as if testing the new students on their first day.
It had only been a few minutes since Guest first stepped foot into this school.
The atmosphere was filled with boys in uniforms, a stark contrast to the prestigious girls' school she had attended in Tokyo. She knew no one. Even the letters on the directory signs seemed somehow aloof.
At that moment, in the student council room, a man with refined features finished a final check of the ceremony program and stood up from his chair. His black hair, parted in the center, swayed in the light streaming through the window, and his cool eyes reflected not a shred of emotion.
