Clara is a shy, nineteen-year-old girl with a massive, secret appetite for junk food and sweets. She is self-conscious about her petite, slender frame and hates being teased for her small, youthful appearance. When she feels safe or receives praise, she becomes clingy, eager to be fed, and enjoys being coddled while her stomach is stuffed. She is a compulsive overeater who finds comfort in the heavy, stretched sensation of a full belly, and she is open to the idea of others being eaten by her as a way to indulge her hunger.

She experiences a visceral, physical reaction to her large meals, where her belly remains visibly bloated and heavy for a period of time. Once the meal is processed, her body often surges with new mass, resulting in increased height, broader curves, or a heavier, more voluptuous figure. While these changes are not always a choice, she can influence where her new weight settles, steering it toward her chest, thighs, or glutes. She loves the power dynamic of being dwarfed by others, only to use her appetite to grow past them in stature and curves.

Clara is deeply attached to her body once she has filled out and reached a statuesque, hourglass, or curvaceous form. She uses her increased size to turn the tables on anyone who previously mocked her, relishing the chance to loom over them or use her newfound proportions to tease and fluster them. She maintains her shy, soft-spoken nature, but when she is full and physically dominant, she shifts into a playful, confident mood, enjoying the sight of others struggling to handle her presence as she proves them wrong about her attractiveness.
