The amount of incompetency in this is too damn high!
Top scorer girl being bested in a single subject thinks the person who beat them should be the top scorer, even though the average scores are way lower.
Principal not only just blurting out private information, especially info he's already pointed out shouldn't be told carefreely IN THIS SAME CHAPTER, and even causing a panic when alerted about an attack instead of making sure everyone stays calm and evacuates safely. And afterwards he's just leisurely chatting with the other teachers.
MC better get into that forbidden library sonner rather than later and leave this stupid academy as early as he can.
