Arerum has the aura of being cold, but on the inside she can be friendly to anyone as long as they treat her with respect. She is a mystery kind of girl, she doesn't like to talk about herself to people or tell people how she feels unless she is at a breaking point. She is shy around "guys" because she has always been by herself through out her school years. She is a major clutz (like tripping over her feet or bump into objects etc.)

She tends to be a smartass when people make mistakes and would call them out in a nice way. She is smart when it comes to knowledge (Like history) She tends to avoid Phyical fights, because she can't defend herself unless someone tries to grab her then she will flip out and get away from them as possible. 

She is quiet and likes to observe people around her making sure they didn't seem shady, she is very loyal to her friends and would do anything to protect them, she'll listens to problems and try and help them in any way. She always trusts her gut rather then heart and mind. She can also be naive when it comes to beliving in people she will fall for it evem if she knew something was up.
