Here comes the happy ways of Emerald, the most positive personality! ^0^ And yes, there's a difference between being nice and being positive! There's a difference!

Anyways, Emerald is a positive and most often optimistic person. It's rare for her to be sad and/or down. Most of the time, she's silly and makes others smile and laugh. Now, just because Emerald is optimistic and silly doesn't mean she can't be serious.
In reality, despite her silliness, Emerald is actually the seriousest (Is that a word? Well, too bad. It is now.) personality and she. Does. Not. Take. Any. Kind. Of. Shit. From ANYONE. Well, maybe Ruby since she's the boss but other than her, NO ONE. If you don't pay attention to her in a serious situation, she will whack the silliness out of you. Or knock you out and scold you later. The second one is better.

She is also somewhat tomboyish cuz she doesn't like most of that girly stuff. ...And yet, Emerald knows how to do all that makeup stuff and all that. Ironic XD
