Operation: Lunchbox - Anime Comedy Poster

Create a finished vertical theatrical poster for an anime comedy movie titled "OPERATION: LUNCHBOX." Show an overconfident young adult rookie spy sprinting through a colorful city plaza while desperately protecting an ordinary lunchbox. Behind them, a chaotic pursuit unfolds: two equally incompetent rival agents collide with a fruit stand, a tiny delivery robot races in the wrong direction, pigeons scatter through the air, and an unimpressed orange cat calmly watches from a café table. The lunchbox should remain the clear visual anchor and the apparent object of absurd international importance. Use energetic diagonal movement, expressive anime poses, exaggerated but coherent reactions, and carefully organized background comedy. Frame the protagonist prominently in the foreground, the rival agents in the middle distance, and a bright Mediterranean-inspired cityscape behind them. Preserve clean silhouettes and readable action without overcrowding the scene. Use a cheerful palette of sky blue, warm cream, tomato red, sunny yellow, and fresh green, with crisp cel shading, polished linework, soft painted backgrounds, and bright afternoon light. Place the exact title "OPERATION: LUNCHBOX" across the upper third in bold, playful red-and-cream lettering with clean spacing and a slight forward tilt. Add the tagline "SAVING THE WORLD BEFORE LUNCH." beneath it in smaller uppercase text. Keep all typography clear and integrated into the poster. Do not include random Japanese characters, fake studio logos, awards, review quotes, credits, or excessive effects. The finished image should feel like official anime movie key art: joyful, fast-paced, character-driven, charming, visually polished, and genuinely funny.
