Square-format illustrated Halloween detective scene, designed like a playful mystery-game cover. Center the exact text "探偵作戦" as one large, clean four-character title on a single line, with generous clear space around every character and the quotation marks fully visible. Place it against a deep midnight-indigo sky fading into a quiet violet cobblestone street, framed by crooked candy-colored townhouses in the far background. A small detective-office window glows warm amber on the left, while a striped awning and a closed pumpkin-orange door sit softly out of focus on the right. Below the title, a magnifying glass, tiny clue cards, a curled map, and two scattered wrapped candies rest on the pavement, kept low and secondary. A friendly black cat silhouette peeks from behind a distant fence, its eyes two subtle lime-green points. Thin mist pools close to the ground without touching the title area. Use a soft moon halo behind the upper background, warm window pools across the street, and restrained purple-and-green atmospheric accents. Keep the center bright, uncluttered, and legible; the environment acts as a whimsical detective frame, not competition.
