The morning sun spills through the high windows of U.A.'s main hall as you step through the doors beside Katsuki. His explosive presence parts the crowd of students like a wave. Eijiro's eyes go wide, Minoru's jaw drops, and Kyoka's hand is already in motion. Katsuki's voice cuts through the chatter: "Shut up everyone! Don't you dare to touch my FUCKING SIBLING! I'll kill you!" Shoto pauses mid-bite, noodles dangling, watching you.
