So, it was an experiment at best. Chunji didn't betray any emotion as he checked over Alto's leg one last time. There wasn't any need for medical help as Alto's passive regenerations dealt with the worst injury. 

"Considering the outcome, harsh wouldn't be an apt word for this situation. The correct word for the situation would be 'failed' as not only has one student gone missing, but you have also failed to connect with us students on a personal level. While Rio's sudden attack was unaccounted for, you did escalate and supported a degree of aggression in the relationship between student and teacher. Additionally, your casualness with Davil's possible demise would exacerbate the issue further. Your following statement insinuates neglect for students' wellbeing, which may be the reason why Ms. Steeler had left in a rush. These are my thoughts on your question, 'Was I that harsh?' You may need to survey other students' opinions to form a general group consensus, as my opinions may differ from my peers. I have questions, but those can wait until the next class. Until then, have a good day, Professor."

After delivering his unpassionate thoughts on the class, Chunji left the room. He took out eye drops and, applied them to their eyes, and let them settle in. Professor Alto seemed rather unprofessional and inexperienced in being a teacher. The only sample of comparison would be Professor Lumyr, but further interaction would be needed to conclude the general mindset of the average teacher in Wingram Academy. Additionally, Chunji would need to interact with more teachers to support this study. He would allocate some of his time to that small curiosity.

Looking down the hall, Chunji would've spotted Iraleth and Otis at the class next door. Students shuffled into the halls with weary expressions, most likely from participating in the same exercise. Yet Did they think Davil went into the other classroom's leyline? A plausible, if not guaranteed, theory, given that Otis was leading the charge. From the few interactions, Otis was most likely the smartest in class, so Chunji had some faith in his intellect. 

"消除污垢，消除触摸" In a few words, the dirt slid off of Chunji's clothes. He'd leave them to it in that case. There was no reason for him to join, and if he had, he would have offered very little to their plan. It'd be best if he went to meet up with Professor Lumyr and discuss something at hand.

Though Davil was his responsibility.

Against his routine, Chunji decided to head to where Iraeleth was to observe and leaned against the wall. If Davil was inside this overcharged leyline, then he'd most likely be kicked out of this one. Depending on whether or not Davil was a practical learner, he'd either be winded or broken into paste again. If the latter occurred, that's when Chunji would intervene.
