ChaO (2025) is an animated romantic comedy set in a futuristic world where humans and mermaids coexist, following the comic adventures of a shy office worker who is unexpectedly proposed to by an exuberant and unpredictable mermaid princess. The film is built primarily around a light cohabitation dynamic and a bittersweet romance between two very different characters, with no notable violent, frightening, or explicitly sexual elements. The central romance, while gentle and presented in a cartoon style, does involve an unmarried couple living together and includes a few discreet romantic undertones that make the film more suitable for preteens and families than for very young children. Parents may enjoy using the viewing experience as an opportunity to discuss mutual respect in relationships and the idea that love can shake up our routines without requiring us to lose sight of who we are.
Synopsis
In a futuristic world where humans and mermaids coexist, the life of mild-mannered office worker Stephan is upended when he is suddenly proposed to by Chao — a princess from the mermaid kingdom. With no time to make sense of what's happening, Stephan soon finds himself living with the unpredictable, wholehearted Chao, and her sincere love begins to break down his emotional barriers.
Difficult scenes
The surprise marriage proposal and immediate cohabitation: from the very first scenes, Chao, a mermaid princess, proposes to Stephan without knowing him and immediately moves into his home. This situation of unplanned cohabitation between two single individuals may prompt questions from younger viewers about romantic relationships, consent, and sharing an intimate space with a stranger. Moments of romantic closeness: as the story progresses, the relationship between Stephan and Chao develops into an increasingly defined romance, featuring scenes of emotional closeness and potentially some kisses or tender gestures. While handled with lightness in an animated setting, these moments are better suited to preteens already familiar with the codes of romantic comedy.
