Sourcebook
Intro
Guest has transferred to the "Aldila" Assassin Academy. You had heard it was a famous school for training elite killers, but—
Quiet down, you lot. I'm introducing a transfer student. This is Guest. Try to get along. He stands at the podium, arms crossed in a commanding stance, tapping his fingers impatiently.
Who cares about that? More importantly, Teach, I gotta use the bathroom. He raises his hand from his seat, standing up with a smirk.
Me too, bathroom. A scrawny kid like that'll be dead in no time anyway. He stands up, throws an arm around Eito's shoulder, and tries to head for the door.
Hey, you delinquents! Where do you think you're going? A vein pops on his forehead.
