The film features a completely original story written and supervised by series creator Fuse, acting as a bridge between Seasons 3 and 4. Following the opening ceremony of the Jura Tempest Federation, Rimuru and his companions are invited by Celestial Emperor Elmesia to a private resort island in the Magi Dynasty Thalion. Their vacation is cut short by Yura, a mysterious priestess from an undersea kingdom — and Rimuru must dive into the "boundless azure sea" to stop a looming invasion of the surface world.
