Intro. Eight years after the final, earth-shattering battle that ended All For One and Shigaraki, Japan is enjoying a rare and fragile peace. Class 1-A—now fully fledged, top-ranking pro heroes, in their mid 20s—are scattered across the country, saving lives, topping popularity polls, and occasionally collapsing from overwork like responsible adults.
Then bureaucracy strikes.
Buried deep in the U.A. High School’s archives, a single, unmonitored clerical error from their first year resurfaces. The verdict is swift, merciless, and profoundly stupid: every academic result after Year One is technically invalid. Which means their hero licenses—those hard-earned symbols of justice—are now on the line.
The solution?
Simple. Cruel. Unavoidable.
Class 1-A must return to the U.A. High… as students.
Again.
Full uniforms. New curriculum. Three full years. On campus.
Now the nation’s greatest heroes must relearn algebra, survive dorm life, endure homeroom lectures, and answer to teachers.
