Stephan, an anxious employee at a shipbuilding company, has big ideas to save the sea. But his life explodes into ecstatic chaos when bubbly mermaid princess Chao proposes marriage out of the blue. Between shopping sprees, giant robots, and actual fireworks, the unlikely pair flounder through their new romance and unlock their true feelings. Crafted over seven years by the acclaimed STUDIO4°C and veteran animator Yasuhiro Aoki, ChaO is an inventive and genre-defying delight bursting with color and character. Equal parts hilarious and heartbreaking, ChaO’s singular narrative is an ode to boundless love.
