"In a situation where society regularly fails them, there would be comfort in EMMA - she is connected to society without being part of it, and she doesn't have human idiosyncrasies. Doesn't derive pleasure from being in a position of authority or power - she is doing her job to serve humanity. There's a certainty in that."

Humans can't answer what a 'Heart' is.

"People like the Thieves... they're rare. Most people don't have the power to fight tooth and nail for themselves and even more often, those that do are still crushed by others. But EMMA doesn't leave them behind, either. She answers their Desires, too."
