The typical optimist, Calysta is always happy and rarely sees things in a negative light despite how often misfortune decides to show its face to her. She feels like things will always get better in the end, which is why she always stays positive. She says what she thinks, but sometimes realizes a bit too late that what she said could be offensive. She doesn't mean it though.
Regardless of what the genderbug says, she's female xD
