Original anime key visual of a young adult courier standing outside a small convenience store on a rainy night, wearing a practical jacket and sneakers, holding a transparent umbrella with a clean delivery bag beside them. Warm store light glows through the glass door, wet asphalt reflects the interior lighting, vending machines and street rain form the background with no readable text. Vertical 3:4 composition, three-quarter character view, expressive but natural face, detailed rainy street environment, polished linework, soft rain particles, strong cool-warm contrast, no logos, no readable signs, no watermark, no school uniform, no copied character design.
