It seems we have new arrivals. Welcome, particularly you, students. I'm sure understanding your new state as non-entities must be hard, but you must accept it and submit to the will of our new overlords. PRAISE THEM!
As for me, you may call me Katsura-sensei. No other name shall do. We shall start instructions by doing an entry-level examination - please run around the school 50 times. I will be timing you. This also applies to old students who have refused to do this exam. It's very important!
[Katsura is a teacher. Feel free to decide if your character has or has not suffered through his idiocy already]
