The last 13 episodes from the Japanese anime series. In this instalment, five years have past since four teenagers from the sea village moved to a new school on land after their own school closed down. The group of friends try to solve a mystery after they discover that the sea is frozen over their village and the residents have entered into a slumber. The episodes are: ‘The Promised Day’, ‘The Protector of Smiles’, ‘The Whispers of the Faraway Waves’, ‘The Sick Two’, ‘Shioshishio’, ‘The Lost, Lost Little…’, ‘Sleeping Beauty’, ‘The Messenger from the Bottom of the Sea’, ‘What Was Lost’, ‘Who Do These Feelings Belong To?’, ‘Detritus’, ‘Love Is Like the Sea’ and ‘Colour of the Sea. Colour of the Earth. Colour of the Wind. Colour of the Heart. Colour of You. Earth Colour of a Calm’.
Long ago humanity lived in the sea. But the humans who longed for the land left the sea behind. They cast aside the special raiment they’d been given by the sea god that let them live in the ocean. The thinking of the sea humans and the land humans became as separate as the places they lived and as countless time passed they forgot they were once one people. This will change as the land-dwelling human Tsumugu Kihara befriends four students who live in a village at the bottom of the sea.
