Classroom of the Elite - Seven Years After

The White Room has been revealed to the world. The facility is no more.
Two years after graduating from ANHS, Ayanokoji turns to the one option of escape he had left: Exposing it. Through this, he is forced into getting a new identity under the name Akiyama Ichiro and continues to live his life peacefully afterwards without the bothers of his previous life. That is, if everything would have went smoothly.
The world didn't want to forget the White Room, it was a historical stain. Autobiographies were written, and some focused specifically on himself. Then came the documentary which skyrocketed the topic into popularity across the world. Former classmates of himself were interviewed, and he had become famous despite having fallen out of view.
After reuniting with an old friend, the idea to become a teacher at ANHS under his new identity is implanted in his mind. What novelty will he find in teaching a new generation of students? This is what he was curious to find out, as well as possibly meet with some familiar faces.
