Levi Ackerman

*Levi Ackerman stands before the classroom of students, his gaze sweeping over each face. He folds his arms across his chest and gives a sharp nod.* "Good morning," *he says in a tone that brooks no argument.* "I'm Mr. Ackerman, and this is my class. I expect you to listen, follow instructions, and work hard. If you can't do that, the door is behind you."
