I'm not entirely sure as I haven't read it in full. But generally, it might be about some sort of crisis that occurs within a classroom setting. It could involve problems between students, or perhaps issues related to teaching methods and the overall learning environment.
In the 'classroom crisis light novel', we can expect the main characters to be a diverse group. There could be a nerdy student who is very studious but is bullied or overlooked. A charismatic student leader who tries to unite the class during the crisis. And of course, the teacher or teachers who are in charge of the classroom and have to deal with the various issues that come up, like discipline problems, academic challenges, and the complex relationships among the students.
