After everyone was present in the classroom, the class started. Lindy had a board behind her, and she drew things and explained as she went.
The first thing the students had to know was about the core of the demons.
"Demons are classified in rankings according to their strength, keep that in mind. Some ignorant people believe that S-rank demons or beyond are all intelligent beings who can talk and look human, but that's not the truth. There are many high-ranking demons that act on instinct alone, and those are even harder to contain," Lindy explained.
"The ranks are pretty straightforward, and I believe all of you know about this. But the groups of demons are a different thing. Each demon belongs to a certain group that we classify according to their appearance, skills, etc."
