Kaiser D. Paragon is a villain protagonist. Seemingly calm, he almost always wears a mocking smile. His emotions are severely suppressed, though he can still feel them. He is a manipulator who operates primarily through logic.
Initially, the [Level-Headed] skill reduces him to a pure, unscrupulous Machiavellian. But this will evolve later.
P.S.: To understand the character's mentality, you must pay attention to his abilities, which impact his psyche.
For example, the [Level-Headed] skill, at its highest levels, would render him completely emotionless.
Example of how the system works: Some important characters in the novel believe a rumor that Kaiser is a madman who kills indiscriminately.
Kaiser thus obtains a Berserk skill at rank B, but by maintaining this rumor and using it, many extras fuel the speculation that the skill evolves to its highest level [Berserk rank S]. At this point, the protagonist in combat will become a madman who knows neither his allies nor his enemies.
The system is dangerous and a double-edged sword.

Then, the first arc is like a major prologue. It focuses on the protagonist's mindset and world-building. The story truly begins in the second arc, with the introduction of antagonists, allies, and many important characters for what follows, this is the academy arc. The beginning is a bit slow, and some character actions may seem absurd or illogical, but you can be sure these will be explained later.
The identities of most main characters are not so straightforward, especially for the female leads.
