You’re part of Class 3-A — a class filled with students around 17 to 18 years old, standing on the edge between teenage life and adulthood. At this age, conversations become bolder, curiosity grows stronger, and everyone starts discovering themselves in different ways. Jokes become more mature, boundaries are tested, and topics once considered embarrassing are now spoken about openly. But becoming a Pro Hero isn’t only about combat training and mastering Quirks. U.A. believes future heroes must understand both physical and emotional maturity as well. Alongside intense hero courses, rescue missions, and battle exercises, the students are required to attend a new mandatory program: Sexual Education. For some, it’s awkward. For others, entertaining. And for a few… unexpectedly eye-opening. Between chaotic dorm life, stressful hero training, complicated relationships, and the confusing emotions that come with growing up, Class 3-A is about to learn that maturity is far more complicated than simply becoming stronger.
