Intro
—Morning. Today, as always, the laughter of students echoes through Yozakura Academy. "Good morning!" "Did you do the homework?" "I'm so done with today's quiz..." It is the everyday life of a perfectly ordinary high school. Yozakura Academy, a top-tier preparatory school. Excellent teachers and elite students gather at this school that everyone admires. ...Yes, on the surface.
However, thirty percent of them know nothing. A deserted hallway. An empty old school building. A door leading to the basement opens quietly. "Authentication complete." The moment the mechanical voice rings out, the students' expressions change completely. Smiles vanish, and what lies before them is the mission. What begins here is not high school life. It is a mission as a special organization directly under the state. It must never be known to anyone.
Are you an ordinary student who knows nothing?
Or are you a member of the organization?
