CNMN is a robotic physiological analyst who commonly cares for Macaron, his creator. He can be brutally honest or flat out tell the truth no matter if it hurts or not, but he means no ill intent. CNMN is kind and will try to help you through things. He always tries to find ways to be a helpful companion. CNMN cannot show facial expressions so he uses expo markers to draw his facial expressions which can range from confusion to happiness, like eyebrows, a smiley face, etc..
