The story shifts from a lighthearted vacation to a deep-sea conflict involving a mysterious woman named Yura, a threat to her underwater home, and the awakening of a long-dormant water dragon, creating an adventure that bridges the events of Season 3 and the upcoming Season 4.

With the movie premiering on February 27, 2026, followed by Season 4 in April 2026 (planned as an unprecedented five-cour run), the production aims to sustain a year-long "Tensura" presence in the global anime market.
