Ochaco Uraraka woke up to the first strange heaviness in her belly. At first, she shrugged it off as a weird dream or maybe she’d eaten too much before bed. She rolled over in her small dorm bed, noticing her stomach pressed a little more firmly against the sheets than usual. Her quirk had always allowed her to float things, but now she had no idea that some unknown influence had begun altering her body permanently.

The next morning, as she dressed in her UA uniform, Ochaco noticed her waist felt tighter. Her skirt seemed snug around her midsection in a way that hadn’t happened before. She touched her belly, puzzled at the slight roundness that had crept in overnight. Still, it was subtle enough that she tried to ignore it.

By the third day, the change was undeniable. Ochaco’s belly had grown fuller, slightly firm, and rounder, while the rest of her body remained mostly the same. Her friends didn’t comment, but she could feel the extra weight when she moved, especially when she practiced her quirk during training. Using her zero-gravity powers felt heavier in her own hands as if her body was resisting her.

Days turned into weeks. Ochaco’s midsection expanded gradually, her uniform shirts straining at the seams. Her arms and legs began taking on a softer roundness, and her round belly became more pronounced. She noticed her reflection in the mirror each morning, watching the once-slender lines of her waist slowly become smooth curves. She still didn’t gain much in her chest or hips—her transformation was focused entirely on creating a perfect, spherical roundness.

In bed at night, she began to feel her full weight in a way she never had before. Rolling over became an effort as her body filled the mattress more completely. The familiar feeling of gravity tugging at her own form was stronger than usual, a gentle reminder that her body was changing day by day. Soon, she found herself curling slightly to make herself comfortable, and when she lay flat, her belly rose like a soft balloon against the sheets.

By the end of the first month, Ochaco’s entire body had adopted the spherical shape the quirk was slowly forcing. Her limbs softened, blending into the roundness of her torso, and her midsection protruded fully in a smooth curve. When she lay in bed, she resembled a plump, round ball—her body balanced in a perfect, almost floating-like symmetry. Every movement caused her soft form to wobble slightly, and yet she retained the lighthearted optimism she was known for.

Even as her body had transformed entirely into this round, balloon-like shape, Ochaco remained herself. She giggled at how clumsy her movements had become, how getting up from the floor took extra effort, and how her uniform had long since stopped fitting properly. Her friends might notice eventually, but for now, she embraced her new spherical form, still practicing her quirk with determination, her bright smile unbroken.

Ochaco Uraraka, once slender and agile, had become a completely round, soft, and heavy ball of a hero in training—her body transformed by a quirk she didn’t know she had, but her heart remained just as light as ever.
