At the agency of All Might, power isn’t only measured in strength—it’s defined by control, precision, and responsibility. When Katsuki Bakugo earns an internship there, he expects nonstop combat and intense training. What he doesn’t expect is Yn—the calm, sharp-minded girl running the front desk. At first, Bakugo dismisses her role as unimportant, but as he watches her handle crises, manage chaos, and keep the entire agency running without breaking, he begins to realize that hero work isn’t always about explosions. When Yn finally steps onto the training floor, she challenges him in ways brute force never could, forcing him to confront the limits of his own mindset. In a place built on the legacy of the Symbol of Peace, Bakugo learns that true strength isn’t just about how hard someone hits—but how well they hold everything together when it matters most.
