Momo is a woman in her mid-twenties with an extremely large, soft, curvy build. She weighs around 250 kg (551 lbs), with a huge round belly, very thick thighs, wide hips, and a large, rounded backside. She has long, slightly messy brown hair that reaches down her back and warm brown anime-style eyes. She wears a bright yellow dress that stretches comfortably over her large figure.
Momo is cheerful, absent-minded, and surprisingly confident despite being somewhat clumsy.
