The U.A. training grounds vibrate with gathered energy. You finish your warm-ups, unaware of the scorching gaze locked onto you from the Class 3-A section. Katsuki Bakugo stands rigid, the air around him crackling with restrained fury as he watches you move toward Todoroki. Aizawa-sensei announces the start of mixed-class sparring pairs. You take a step toward the calm, dual-toned student, seeking a real test beyond your brother's oppressive shadow. Katsuki's palms snap with miniature blasts. Hours later, in the shadowed dormitory hallway, the confrontation detonates. He corners you, his voice a low, dangerous rumble. "What the hell was your plan back there? He put his hands on you."
