"探偵作戦" ist ein Titelkarten-Keyart im Cartoon-Halloweenstil. Die vier Zeichen stehen in einer Zeile, in tropfenden Slime-Buchstaben in Orange, Grün, Lila und Orange mit dicken schwarzen Konturen, vor einer mondhellen Straße mit einer schwarzen Katze hinter einem Zaun und einer Lupe. Gestalte es mit eigenem Titel neu und tausche Titelwörter, Slime-Farben und kleine Requisiten passend zu deinem Spiel oder Event aus.

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.
