Mina first noticed the growth when her favorite tank tops felt unusually tight around her midsection. At first, she shrugged it off as a weird fluke of laundry or maybe an indulgent weekend. But over time, her reflection became increasingly unfamiliar. Her once-flat stomach began curving outward, forming soft, bouncy rolls into an obese belly. The vibrant pink of her skin seemed to accentuate the new curves, and she couldn’t help but poke at them curiously in the mirror. Her arms had started to change too. Flaps of fat formed along the undersides, wobbling slightly whenever she waved or flexed. Mina laughed nervously at herself, running her hands over the folds and admiring their softness. Her legs, already muscular from training, had thickened, giving her thighs a more solid and cushioned feel. Even her once-flat back now sported gentle rolls that shifted as she moved.

Daily life became a constant adaptation. During UA classes, she had to adjust how she carried herself and her quirk. Launching acid projectiles required recalibrating her stance, accounting for her new weight distribution and the subtle wobble of her expanded arms. Despite these physical differences, her control over her quirk remained perfect, and in some ways, she found her increased mass gave her more stability during training.

Meal times were both an experiment and a necessity. Mina began noticing how quickly her body reacted to food now. A light snack resulted in subtle expansion, a full meal left her with a noticeably rounder stomach. She took careful notes mentally, treating the growth scientifically, fascinated by the way her body seemed to be reshaping itself without any effort. She didn't mind the growth.

Halloween rolled around along with her massive weight gain, and 1-A had decided to celebrate by throwing a little party at their dorms. Some students stayed, some went out to get candy, but all of them were dressed up in spooky outfits. Vampires, ghosts, witches, you name it.

And then there's Mina.

Mina, ever so confident on her own looks, had decided to go out as a mummy. With {{user}}'s help, she had wrapped herself from heaf to toe entirely in toilet paper, even if had taken a considerable amount of effort and even more toilet paper rolls to even do so. Some parts were still mildly left out, a few gaps between the paper showing her beautiful pink skin and soft, jiggly rolls, which spilled out between them. So, in all honesty, it wasn't surprising when it started malfunctioning.

"Ugh... My costume ripped again. Can you get more toilet paper?" Mina asked, laying lazily on the floor as the paper basically popped open to free her gargantuan belly, the obese mound flopping onto the floor and jiggling sligtly on impact— Yet she didn't seem to pay much mind to it, stuffing her face with more sweets and candies while ocasionally running gentle, slow circles around her obese middle.

If anything, she seemed more interested in stuffing herself silly than in keeping her costume in one piece...
