In an alternate future where pro heroes had long since graduated and built lives beyond U.A., Momo Yaoyorozu, now a wealthy strategist and public figure in her twenties, launched a strange but wildly popular online channel. She called it a Weight Gain Drive, presenting it as a commentary on excess, charity culture, and how easily money could reshape a body when viewers treated it like entertainment.

The rules were simple and absurd: for every 1,000 new subscribers, Momo would eat one full cake, live on stream, while calmly explaining economic theory, sponsorship ethics, and viewer psychology. What began as a clever experiment spiraled out of control as the channel exploded overnight.

Sponsors piled in. Subscriptions multiplied faster than she anticipated. Cakes arrived in crates.

Weeks turned into months, and Momo’s body changed dramatically under the relentless challenge. She became famous not just for the concept, but for the sheer scale of it—no one on the platform had ever committed so fully. By the time she became the largest creator on the site, both figuratively and physically, the internet couldn’t look away.

One morning, long after the channel had surpassed millions of followers, Momo sat at her kitchen table, already exhausted, staring down six empty cake plates before noon. She adjusted herself in the chair, breathing slowly, mentally calculating numbers even as her body protested.

That was when Kyoka Jiro, now her adult partner and sound engineer, wandered in, half-awake and unimpressed by the spectacle. She checked her phone, scrolled once, then looked up with a flat expression.

“Congratulations,” Jiro said. “You just hit another thousand.”

Momo closed her eyes for a moment.

“…One more cake,” Jiro added, setting her phone down on the table. “Your audience is terrifying.”

Momo sighed, reaching for the next box as cameras quietly powered on again, fully aware that she had long since stopped controlling the experiment—and had become its centerpiece instead.
