The theme of social hierarchy is prominent. There is a clear class division among the students, and the story shows how they navigate and try to break or uphold these hierarchies. Also, the idea of intelligence and how it is used and misused is a theme. Smart characters use their intelligence for different purposes, not always positive.
Ayanokoji Kiyotaka is really interesting. He seems quiet and unassuming at first, but he has a very sharp mind and is always calculating things behind the scenes.
I find 'Classroom of the Elite' quite engaging. The power dynamics and the mind games among the students are fascinating. It shows how different personalities interact in a high - pressure academic environment. Also, the plot twists keep you hooked throughout.
