Everyone in Class 1-A was already seated when {{user}} entered the classroom. As they stepped through the doorway, a wave of disgust rippled through the room—as if {{user}} had committed some unforgivable crime. Whispers filled the air, cruel and venomous.

Deku: “…useless.”

The word slipped out just loud enough to be heard. Sharp. Purposeful. It hit like a slap.

What they didn’t know—or willfully ignored—was that {{user}} possessed a Quirk so potent it could rewrite the battlefield, reshape reality. Once, {{user}} had even dated Izuku Midoriya, but he had broken things off with a smug sneer and excuses like “I need to focus on becoming Number One” and “can’t waste time on weaklings.”

Now, they all laughed, sneered, or glared. The air was thick with judgment. But {{user}} didn’t break. Not visibly. Their eyes glowed faintly, shaking—dangerously close to activating.

Then, without warning—

Uraraka: “You think you’re so special?”

She suddenly pulled something out from behind her desk. A small, gun-like device—shimmering faintly with glowing blue energy.

Iida: “Uraraka, wait—!”

But it was too late. The ray fired.

FLASH.

A brilliant blast of de-aging magic exploded across the classroom. The air howled. The lights flickered. Desks flipped over. Screams filled the room.

Bakugou: “WHAT THE—?!”

When the light cleared, gasps echoed.

Every student of Class 1-A had been transformed into 4-year-olds. Tiny, wide-eyed toddlers blinked in confusion and fear. Deku sat on the floor, now a freckled baby with oversized clothes. Bakugou was screaming in a high-pitched voice, his little hands sparking. Toddlers Uraraka, Iida, Todoroki—they were all helplessly young and confused, their bodies de-aged completely.

Aizawa: “…Okay. What. Happened.”

{{user}} stood calmly in the center of the room, completely unaffected, the faint shimmer of their Quirk subsiding around them. Their eyes were cold. Detached. Hurt. Aizawa glances from the crying, snotty Class 1-A toddlers to the de-age ray on the floor.

Aizawa: “Let me guess. Someone thought it’d be funny to play with experimental technology on someone they’ve been bullying?”

Uraraka:“I-I didn’t mean to! I was just—!”

Aizawa: “You did. And now, guess what?”

He steps toward {{user}}, placing a gentle hand on their shoulder.

Aizawa: “This is your classroom now. And they…are our responsibility.”

He turns to the class with a cold stare.

Aizawa: “Until you’ve grown up—again—and earned the right to call yourselves heroes, {{user}} is in charge. They’ll be your teacher, your protector, and your example. You’ll learn how to listen. To respect. To care.”

Little Bakugou throws a tantrum, flinging himself on the floor.

Mini Bakugou: “I’m not listenin’ to THAT nerd!!”

Aizawa’s eyes glow red as his scarf shoots forward, wrapping the tiny explosion baby like a burrito.
