- Gain as much weight as possible by the last month of the year
- Train Quirk usage alongside body growth
- Final tournament decides the winner
Lunch hour at U.A. High had never been quiet, but today was worse.
Mina Ashido leaned against the cafeteria table while overhearing a conversation nearby.
“…Studies say increased body fat can improve Quirk performance,” a student whispered.
Mina’s eyes widened.
“Wait, seriously?!”
The student nodded confidently. “More stored energy. Better output. Better durability.”
Mina practically launched out of her seat.
Ten minutes later, every girl in Class 1-A sat around a table while Mina slammed down a notebook.
“I HAVE AN IDEA!”
Momo Yaoyorozu blinked. “That sentence usually worries me.”
Mina pointed dramatically.
“A weight gain contest!”
Silence.
Then Ochaco Uraraka tilted her head. “How would that help?”
Mina grinned.
“If extra fat helps Quirks, then we should train with it!”
Surprisingly, several girls immediately started thinking about it seriously.
Momo adjusted her posture. “My Quirk converts fat into materials… technically, additional mass would improve production capability.”
Kyoka Jiro crossed her arms. “Extra body weight could help stabilize recoil from my sound attacks.”
Tsuyu Asui nodded slowly. “A larger body could improve water storage and durability, ribbit.”
Ochaco looked embarrassed. “Well… maybe heavier mass would help momentum after releasing Zero Gravity…”
Mina slammed the table excitedly.
“THEN IT’S DECIDED!”
⸻
The contest officially began the next day.
Rules were simple:
Even {{user}} joined the challenge.
At first, everyone treated it casually.
Extra desserts.
Larger lunches.
Protein-heavy meals.
But the pace accelerated frighteningly fast.
⸻
By the second month, visible changes had already appeared.
Mina proudly showed off her heavier stomach. “Look! My acid attacks last longer now!”
Jiro sat heavily in a reinforced chair nearby. “My bass vibrations actually ARE stronger…”
Momo quietly ordered another full meal while taking notes.
“I can create larger objects now without exhausting myself.”
Ochaco groaned while trying to squeeze into her hero suit.
“I think my cheeks got bigger…”
Tsuyu calmly sipped from a giant smoothie.
“Mine too, ribbit.”
⸻
Time skipped rapidly.
Summer arrived.
Then autumn.
The contest stopped feeling temporary.
The girls grew larger month after month, their eating routines becoming ridiculous.
Entire cafeteria tables disappeared beneath food trays.
Training uniforms were replaced repeatedly.
Support companies started manufacturing reinforced furniture specifically for the dorms.
Even walking through hallways became slower.
Yet strangely…
Their Quirks really WERE improving.
Momo created artillery-sized equipment effortlessly.
Jiro’s sound blasts cracked concrete walls.
Ochaco could launch massive debris after releasing gravity.
Mina’s acid spread across entire training fields.
Tsuyu became nearly immovable physically.
The contest became serious.
Competitive.
Obsessive.
⸻
Then came the final month.
The dorm common room looked completely different now.
The girls of Class 1-A had become enormous.
Every participant weighed at least 600 pounds.
Several exceeded far beyond that.
Mina alone weighed over 900 pounds, sitting proudly across an entire reinforced couch while drinking a melted milkshake straight from the container.
“This is AWESOME,” she laughed.
Momo adjusted herself carefully nearby, her massive body sinking into specially reinforced cushions.
“My Creation output has increased by almost three hundred percent…”
Jiro groaned while standing up slowly. “Walking upstairs is a nightmare now…”
Ochaco bounced slightly in place after accidentally activating her Quirk on herself again.
“W-whoa!”
Tsuyu remained oddly calm despite weighing enough to visibly shake the floor when she moved.
“Ribbit. I cannot fit through normal doors anymore.”
The final tournament arena had to be modified before battles could even begin.
Concrete reinforcement.
Wider entrances.
Heavy-duty
