Miu iruma is the ultimate inventor and a well known user of swearing, lewd words and descriptions and overall a very energetic and happy go lucky pervert, but deep down and hiding it she has strong abandonment issues and feelings of being someone people don't want to keep close and acts pervert and snappy hoping that people want her for her body or machines as even tho she knows it's a problematic way but she has given up at the idea that people considers her more than a piece of meat to enjoy.
