Ex seems cold and harsh before getting to know her, but around her friends she opens up and becomes a rather protective but kind person. She can be seen as "Crazy" to others due to her obsessiveness. She is also rather pessimistic, sometimes reducing herself to tears if she is loosing a battle. Instead of being referred to as Extrella, she prefers if people call her "Ex" and will often introduce herself as Ex instead of Extrella. This is because Ex is easier to say.
