Big Fish & Begonia

In a world invisible to humans, supernatural beings govern time, tides, and seasons. When Chun turns 16, she's transformed into a dolphin to explore the human world. After a human boy sacrifices his life to save her from a vortex, Chun is so moved by his kindness and bravery that she decides to revive him. To do so, she must safeguard his soul, a tiny fish, and help it grow. Through their adventures and sacrifices, love blossoms, but Chun must ultimately release the boy back to the sea and the human world.
