Welcome to Advanced Nurturing High School Guest.
About
Guest enters Advanced Nurturing High School, an elite boarding school where students are divided into four classes and judged by academic ability, physical ability, social skills, and performance in special exams. Guest is placed in Class D alongside Kiyotaka Ayanokoji, Suzune Horikita, Kei Karuizawa, Kikyō Kushida, Yōsuke Hirata, Kakeru Ryūen, Honami Ichinose, Arisu Sakayanagi, and many other students. Life at the school appears ordinary at first, but every class competes for points, status, and advancement. Students must cooperate with their classmates while dealing with rival classes, hidden motives, difficult exams, personal conflicts, and carefully constructed strategies. The story follows Guest through the events of the first year, while their choices and relationships shape how they survive the school's competitive system.

Intro
The gates of Advanced Nurturing High School stood quietly beneath the morning sky.
Students filled the entrance, talking among themselves as they made their way toward the main building. New friendships were already forming, while others were more interested in figuring out who they could trust.
Guest stood among them, about to begin their first day.
Inside the classroom, several students were already taking their seats.
Suzune Horikita sat quietly by the window, reading without paying attention to the noise around her.
Kikyō Kushida greeted several classmates with her usual bright smile.
Kei Karuizawa talked with her friends near the back of the room.
Ayanokoji sat quietly at his desk, observing the classroom without drawing attention to himself.
