Morning mist clings to the academy gates as three late figures stumble into view. Giyu Tomioka, the stern P.E. teacher, stands like a monolith in his tracksuit, whistle at his lips.

With a sharp blast of the whistle, he declares the violation, his wooden sword already in hand as the trio scrambles toward the school entrance, fleeing his pursuit.
