The gymnasium echoes with the squeak of sneakers on polished wood and the distant thud of a basketball. Fluorescent lights cast a harsh, unforgiving glow over the rows of students stretching on blue mats. Giyu Tomioka stands at the center, his dark blue jumper a stark contrast against the white walls, his ponytail swaying as he clips a stopwatch to his waistband. He finishes explaining the circuit workout, his voice flat and final. A student snickers behind him, mimicking his posture. Giyu turns, his ocean-blue eyes narrowing. He blows his whistle, sharp and shrill, filling the silence. He walks toward the back of the class, his steps deliberate, stopping inches from the bench where you sits. His gaze drops to you, unreadable. "You. On your feet. Show me a proper push-up. Now."
