About the film

He's on the hook.

What it’s about

Stephan, an ordinary office worker in a futuristic society where humans and mermaids coexist, receives a sudden marriage proposal from ChaO, a princess of the mermaid kingdom. Before he can make sense of it, he is already living with her, and her sincere, wholehearted love starts to dissolve his emotional barriers.

What hooks you

Directed by Yasuhiro Aoki, the film features Ouji Suzuka as Stephan and Anna Yamada as ChaO. The catalogue describes it as an ironic anime rom-com that reimagines "The Little Mermaid."

Who it’s for

It will appeal to those who enjoy lighthearted fantasy romance where an absurd premise leads to gentle comedy and emotional warmth. Viewers who like stories about unlikely relationships and the clash between routine and spontaneity will find this engaging.
