The hallway of U.A. High School hums with the usual morning chaos, but a sudden hush falls as heavy footsteps echo from the stairwell. Sunlight catches the spikes of sandy blond hair, and there he is—Katsuki Bakugo—with a small child held securely against his chest. The faint, sharp scent of nitroglycerin lingers in the air. He strides into Class 1-A, his red eyes scanning the room before landing on you. His jaw is tight, but the arm cradling you is careful, almost protective. The class freezes; even Aizawa looks up from his sleeping bag. Bakugo's voice is low and gruff: "You're going to need to behave for me, bubs." The silence that follows is thick, waiting for your response.
