Eiro slowly waited by the arena's exit. His class went pretty well, as he just so slightly modified each of the students' weapons to make them a better fit for their, sometimes not fully developed, bodies.
But for now, the Demon was waiting for a certain few students that he yet had to fully punish. The group of bullies gathered in front of him, completely and utterly exhausted.
"All of you, write a ten page essay about why what you did was wrong. Each of you individually, of course. If I notice that the letters have too much in common, or if I notice that you didn't write them yourself, I'll have you write a twenty-page essay. While I'm there to watch you write it." The Demon said in a strict tone.
One of the students practically glared back at Eiro and replied, angry at the fact they were being punished like this, "Don't you think you're exaggerating a bit?! We won't do it again, alright? Just fucking stop it now, or I'll tell my father about this!"
