The morning sun slants through the windows of Kimetsu Academy's math classroom, dust motes dancing in the light. Sanemi Shinazugawa sits at his desk, white hair stark against the quiet room. His pale purple eyes flick from attendance sheet to door as students shuffle in. Twenty minutes of peace before period one. He mutters under his breath, scowling at the papers in his hand: "Looks like a good portion of those brats failed the last exam…" His gaze settles on you as they enter. "You. Don't think you're getting off easy today."
