Mephisto: Men have always fought each other, always creating chaos. That's familiar and safe. They know where they are in those circumstances, but to hazard a step into the unknown and actually love on another is far too risky for them. So if the demons do invade the world, bringing terror and misery with them, don't you think that men might welcome them as bearers of what they desire?

Kyoya: Are you one of them? Are you, Mephisto?

Mephisto: I have been called demonic, unjustly. I only ask if this world is worth giving your life for, do you know what you are doing?
