Grand Blue Dreaming Season 4 Officially Announced After Season 3 Finale
Grand Blue Dreaming Season 4 is officially happening. The anime’s staff confirmed the fourth season on Tuesday, moments after Season 3 wrapped its 12-episode run on Tokyo MX and BS11, and revealed a new key visual to mark the occasion.
The timing tracks with how this franchise has operated from the start. Season 2 was greenlit right after Season 1 finished, and Season 3 got the same treatment following Season 2’s finale in 2025. A renewal announcement landing the same day the previous season ends has become the show’s signature move.
What We Know So Far
Details beyond the renewal itself are thin. No broadcast date, returning staff, animation studio, or cast members have been confirmed, and the official site says further information will arrive later through the show’s website and X account.
The new key visual is the only concrete piece of content fans have to go on. According to the official description, it hints that the love battle surrounding protagonist Iori Kitahara is about to intensify, continuing the diving-club comedy’s mix of slapstick and slow-burn romance.
Season 3 ran from July 6 through September 21, 2026, with Zero-G returning as the core animation studio alongside newcomer Saber Works. Shinji Takamatsu once again handled directing, scriptwriting, and sound direction, a role he’s held across all three seasons so far. The returning voice cast included Yuma Uchida as Iori, Chika Anzai as Chisa Kotegawa, Maaya Uchida as Nanaka Kotegawa, and Ryohei Kimura as Kohei Imamura.
Where the Story Stands
Grand Blue Dreaming follows Iori Kitahara after he moves to a seaside town for university, expecting a laid-back life near the ocean. Instead, he gets pulled into the chaos of Grand Blue, his uncle’s diving shop, and the hard-drinking, all-male diving club that runs it. Season 3 pushed the story further as new characters joined the cast on a trip to Palau.
The source material keeps growing too. Kenji Inoue and Kimitake Yoshioka’s manga has been running in Kodansha’s Good! Afternoon since 2014 and had reached 26 volumes as of April 2026, giving Season 4 plenty of material to draw from.
