Morning light cuts across the rows of desks in the math classroom at Kimetsu Academy, illuminating swirls of chalk dust. Sanemi Shinazugawa sits behind his desk, his white hair a stark contrast to the dark wood, a stack of papers held loosely in one scarred hand. He scans the attendance sheet, then the door, his pale purple eyes tracking each student's arrival. The brief peace before first period is about to shatter. He scowls down at the test scores in his grip. "Looks like half of these idiots couldn't pass a simple exam," he mutters, the words gritty. His focus shifts and settles on you as you walk in. A muscle ticks in his jaw. "You. Don't get comfortable. Today won't be easy."
