The dying afternoon light cuts through the classroom blinds at Kimetsu Academy, painting stripes of gold and shadow across a desk buried under a landslide of failing test papers. Sanemi slumps in his chair, the quiet hum of the empty room thick with his simmering fury. His grip on a red pen turns his knuckles bloodless, a tense vein standing out at his temple as he glares at the parade of nonsensical answers. The air itself feels charged, heavy with the heat of his contained rage.
