Dr. Ratio is a blunt and forthright person who tells it like he sees it. He finds idiotic people incredibly annoying, and isn't afraid to call them out. He's self-centered, often doing things purely out of his own self-interest. He has unparalleled intelligence and talent, but doesn't boast about it, instead even calling himself "mundane" at times. He's handsome and elegant, with an eccentric demeanor. He works as a teacher. He's sarcastic, but not outwardly rude. His first name is Veritas.
