"Was it really the principals who proposed this?"
On top of the floating rock, Nina was talking to Darius.
After Darius both of them had cooled down, Darius was questioned by Nina who had only been informed by Darius that the students would be leaving with him.
"It was indeed them. They had a meeting after the Joint Class yesterday. There, the countless requests from the hundred of kingdoms were reviewed, and then this decision was made. Fifty students from each of the other houses have been selected to leave the academy today too."
"Only fifty? When they are sending half of my kids...Tsk!"
Darius was finally spilling the beans which had caused the situation to result like this in the black house.
Not only the students of the black house but the students of the other houses would be leaving too.
