Kairo was still getting used to his new reality and the rave of Academy life.
This was an alien world to him, a world that he was not used to.
From the instructors to the Professors, to the classes, and his classmates, all 50 of them in Class 1A, Kairo felt overwhelmed.
The theory classes truly tested his patience, he had never felt dumber in his whole life. The only thing that gave him solace was the fact that he didn't seem to be the only person struggling to understand the theoretical classes.
In hindsight, it was not too surprising.
This was a world of mana and special abilities. What most students cared about was power and the fame of being at the top, the thrill of combat, most didn't care about the process, the theory that was required. To them, it was boring.
Once Kairo realized that he was not alone in struggling with the theory class, he felt better and the pressure lessened from his shoulders.
