The official website for the Grand Blue Dreaming anime revealed a key visual and the opening theme song artist for the third season on May 24, a date recognized as "Scuba Diving Day" in Japan due to a wordplay on "Go to Sea."

This season will take the cast to Palau, marking the first time the setting has been outside Japan.

The second season ended in September 2025, and the third season was announced shortly after its finale.

The manga by Kenji Inoue and Kimitake Yoshioka began serialization in Kodansha's Good! Afternoon magazine in April 2014 and has 26 volumes as of April 2026.
