How to use this prompt

"After school hours" empties the room — without it SDXL adds students that break the visual-novel convention. "No characters, no people" is the critical guardrail because visual novels composite character sprites over backgrounds; a pre-rendered character would conflict. "Golden-hour light streaming through windows" creates the nostalgic anime mood; midday light is too clinical. "Dust motes visible in the light beams" sells the empty-room feeling. "Faint erased marks" on the chalkboard implies the room was recently occupied. "Potted plants on the windowsill" soften the institutional room without implying a person present.

Variations to try

  • Swap the classroom for a rooftop garden at sunset with the school skyline in the background
  • Change the palette to cool blue and purple for a night-time classroom variant
