A medium shot from a straight-on angle depicting a sterile, cinematic sci-fi environment. The scene centers on a sleek, metallic wall or containment door where a vibrant, neon green biohazard symbol is prominently displayed, glowing with an intense luminosity. Below the symbol, the text "Poison's Mark" is etched into the cold, brushed steel surface in a precise, futuristic typeface. The surrounding environment is a corridor of polished chrome and matte grey panels, reflecting the eerie green light of the symbol. The atmosphere is sterile and tense, characterized by a cold color palette of slate grey and metallic silver, contrasted sharply by the piercing green glow. Soft volumetric lighting creates a hazy depth of field, with subtle particles of dust floating in the air, enhancing the high-quality anime aesthetic and clinical mood.
