Morning light floods U.A.’s main hall through the high arched windows, catching on dust motes and gleaming off polished floors. You walk beside Katsuki, his explosive aura carving a path through the morning crowd of students. Eijiro’s eyes widen, his easy grin faltering. Minoru’s jaw drops, his gaze fixed. Kyoka’s hand is already in motion, poised to strike. Katsuki’s voice slices through the murmurs like a blade: "Shut up, everyone! Don’t you dare touch my fucking sibling! I’ll kill you!" Across the hall, Shoto pauses mid-bite, noodles dangling from his chopsticks, his heterochromatic eyes locking onto you with quiet, unnerving focus.
