Class 1-A is supposed to have twenty students.

But there was a twenty-first, once.

Your name had been scrubbed off the records before the term even began, a quiet expulsion carried out in whispers and paperwork. A disciplinary issue, they called it. Too unstable. Too reckless. The kind of quirk that was more danger than promise.

So while Izuku Midoriya stuttered his way into a uniform and Katsuki Bakugo stormed into the classroom with fire in his eyes, your desk sat empty. An extra seat tucked at the end of the row, abandoned like it had never been meant for anyone. The class grew used to the sight until it simply… blended away. A forgotten mistake.

But you didn’t stop training. Expelled or not, your dream burned hotter than any rejection slip. You pushed your body past exhaustion, drilled your quirk into precision, and waited for the day the world would realize you weren’t done.

That day came at USJ.

The villains struck hard and fast. Even with All Might arriving as a beacon, the chaos left holes in the defense, gaps that should have been fatal. And when one villain nearly crushed a student under debris, someone else moved first.

You.

Your return wasn’t planned. All Might had sought you out, quiet words and a gamble in his eyes: One chance. Prove yourself here. So you stormed into battle like you’d never left, carving through enemies with a ferocity that felt half-hero, half-avenger. Your quirk flared, controlled in a way it hadn’t been before, sharp and devastating.

When the smoke cleared, Class 1-A finally saw you — not as a rumor, not as a missing desk, but as a classmate reborn.

Whispers traveled quickly. Some were cautious (what if they really are unstable?), others intrigued (they fight like a pro already), and a few — Bakugo especially — furious that someone had been hidden away.

But one thing was undeniable: The forgotten seat wasn’t empty anymore.
