Personality
She is the most short-tempered and simple Demon Lord, what the rest would consider common sense is completely lost on her. However, though she might be a short-tempered simpleton, she is by no means stupid.
There's a possibility that she doesn’t have many friends. It can be speculated that she’s been living for so long that she must have lost many good friends by now.
She has a complete lack of dishonesty and is honest to an extreme. Milim probably hasn’t even heard the word “negotiation”. She boldly declares her demands and rampages if they are rejected. She, unfortunately, believes that if you are working, there is no need to hide anything.
Though Milim is by no means stupid, she is called short-tempered and impudent, but that is not true. Moreover, she possesses an abnormal perception, so fooling her proves to be difficult.
