A cute rubber duck boy character named "RUHiA" embarks on a grand adventure heading to Japan and meets a Japanese woman named "Mirai." Create this as a live-action movie poster with cinematic quality. The rubber duck character should be rendered as a tangible, real-world rubber duck toy but with expressive, character-like qualities. The human character should be photorealistic. Include movie poster elements: title treatment, billing block, dramatic sky background, adventure journey imagery, and the emotional meeting moment between the small rubber duck hero and the human character. The poster should convey warmth, adventure, and cross-cultural friendship.
