New kid Kai is talented but adrift, spending his days sulking and isolated in a small fishing village after his family moves from Tokyo. When he demonstrates a proficiency at making music on his synthesizer, his classmates invite him to join their nascent garage band, but their practice sessions soon bring an unexpected guest: Lu, a young mermaid whose fins turn to feet when she hears the beats and whose singing causes humans to compulsively dance - whether they want to or not.

Very beautiful don't miss it.
9 April 2018 | by ibrahimz-32228See all my reviews

It is not a conventional Anime at all still it is very beautiful with a deliberate playfulness witch you will like. The mermaid itself and the characters all are amazing. The first half is more beautiful than the second but at whole it is a fine Anime film which is worth watching. Just do not miss it a recommendation.
