Sunny, living up to her nickname, has a very vivid and lively personality. Most of the time, there is a shy yet true smile on her face, and her tone of voice usually notifies people of her good mood. However, her temper can take a very swift turn for the worse if her buttons are pushed (see "Dislikes" section). She is also quite fearful and uncertain of specific things, and she tends to overreact to small problems.
