Angela was pretty pissed because she could feel that the auras around the students had changed.
For an entire semester, she made sure that the students would improve, and due to that their auras started to appear powerful and dangerous.
Now after a month of break, most students' auras became tamed. Only a few kept diligently working while others enjoyed luxurious lives at their homes.
It was like the fire she lit was doused in water. Of course, she is pissed, and moreover, they didn't even react after her appearance.
The academy might be considered safe but threats may appear even in the safest places. It was said that we should be always aware of our surroundings and be alert for possible threats but we didn't.
Even I was not aware and alert. I only sensed her because of my rank and others failed to do so because of their low rank but that was something only I knew, Angela doesn't. It earned me a few more brownie points.
