At first, Momo barely noticed the gradual transformation. Her uniforms felt snugger across the chest and waist, but she attributed it to irregular laundry or a change in fabric. By mid-week, her once-flat stomach began rounding outward, pressing against her blazer. She paused, examining herself in the mirror after class, noticing the subtle folds forming along her sides. “Interesting…” she murmured, curiosity outweighing alarm.

By the end of the first month, the changes had become impossible to ignore. Her stomach protruded prominently, forming a soft, firm dome, and multiple rolls had appeared along her sides and back. Even her arms and thighs had thickened slightly, giving her an overall heavier, more rounded appearance. Each movement required recalibration; walking up the dorm stairs, previously effortless, now demanded careful attention.

Momo’s days became exercises in adaptation. During class, she would strategically position herself at her desk to accommodate her expanding belly, ensuring she could still reach her supplies with ease. Her quirk, however, remained fully functional. Creating objects required careful consideration of her new body weight, as her center of gravity shifted with her larger frame. She found herself adjusting her stances, leaning slightly backward when summoning larger constructs to avoid toppling forward.

Meals became moments of reflection. Unlike some of her classmates who ate without much thought, Momo approached each bite analytically, aware that her body was reacting to something she didn’t fully understand. Still, she indulged in moderation, balancing sustenance with self-awareness, her intellect guiding her through a body suddenly unfamiliar yet undeniably hers.

Her fat rolls became a source of fascination. She would run her hands over the folds along her sides and back, noting how soft they were compared to the taut skin she remembered. Her large belly was warm and pliable, resting gently against her thighs when she sat cross-legged. Even her posture changed subtly; she learned to sit and stand in ways that distributed her new weight comfortably.

Training at UA was the greatest challenge. Hero exercises she once performed with precision now required new strategies. While her quirk allowed her to create defensive walls or weapons effortlessly, her movements were slower, her spins and leaps modified to accommodate her size. Yet she persisted, her determination unwavering. She experimented with techniques that leveraged her fuller body, using the weight of her belly and thighs to stabilize constructs or anchor objects.

Social interactions became a mixture of surprise and admiration. Some classmates offered cautious praise, others stifled giggles, but Momo responded with grace and quiet confidence. She embraced her changing appearance with poise, often joking analytically about her quirk’s unintended side effects. “It appears my body has… expanded parameters,” she would note, adjusting her uniform neatly around her belly and folds.

By the end of the semester, Momo had fully adapted to her new form. Her large belly and soft rolls were permanent reminders of the quirk that had altered her, yet they no longer hindered her. Walking through UA, she moved with confidence, her every step deliberate and controlled. In the dorm, she practiced her quirk, experimenting with new techniques that accommodated her rounder frame. Her intelligence and adaptability remained undiminished, proving that change, no matter how unexpected, could be integrated with grace and skill.

Momo’s reflection in the mirror became a daily affirmation. She saw herself not just as the girl who had grown rounder, but as a capable hero in every sense: intelligent, resourceful, and resilient. Her belly, her rolls, her fuller body—they were all part of her now. And as she prepared for another day of classes and training, she smiled, confident that she could face any challenge UA threw her way, quirk, body, and mind fully aligned.
