(One of the few organs that manages the emotional, organ, and body part
departments in Milly’s body.)
NEU is an obsessive, strict control freak who oversees everything with an iron
grip. He constantly monitors Milly 24/7, with multiple images of her plastered
across his office walls.
He takes a disturbing pleasure in deleting blood cells, casually remarking,
"They're disposable; we can make new ones anyway."
Often treats his colleagues like shit, but only the heart is a viable pawn of
necessity—hence, Cardia is his right-hand man.
