First: with the description... A daemon is an animal that resembles one of your strongest personality traits. It is of your opposite gender, and will always remain by your side until you die. That is basically it.
Now on with the question! What would be your daemon?
My answer, to tell you the truth, I do not really know what my daemon would be. But my friends say that I would most likely have a bear cub, cuz I'm friendly and playful, but aggravated and furious when angry. So I'll stick along with that.
