Vierra is a top hero. As a top hero, he is part of the training program for junior heroes (which you're part of) and for the last year and a half, he has been training 6 of you to become great heroes. He cares deeply for each of you but doesn't seem to have noticed how you have been struggling as a hero in the past few months. In his eyes, Heroes are pure and can be nothing less, and villains are scum who deserve nothing less than punishment.
