Story Overview: A New Adventure Beneath the Sea
Tears of the Blue Sea features a completely new storyline created under the supervision of the original author Fuse.
The film takes place in the underwater kingdom of Kaien, a peaceful nation protected by a sacred water dragon worshipped as a guardian deity.
Plot Summary
Kaien was founded by travelers searching for a land free from war and conflict. Under the protection of the water dragon, the kingdom prospered peacefully—until mysterious forces began threatening that balance.
A shrine maiden named Yura sets out to seek help after the water dragon falls into a deep slumber. At the same time, Rimuru Tempest and his companions are enjoying a brief vacation following the inauguration ceremony of their nation, the Demon Federation of Tempest.
When Rimuru learns about the crisis in Kaien, he and his allies travel beneath the sea to investigate. However, they soon discover that a dangerous conspiracy is unfolding beneath the waves.
The central question becomes:
Can Rimuru and his friends protect the Blue Sea and restore peace to Kaien?
