The long wait is over. Grand Blue Dreaming Season 3 premiered today on Crunchyroll — and for the first time in the series’ history, Iori Kitahara and the Peek-a-Boo diving club are leaving Japan behind, taking their particular brand of chaotic, half-dressed energy all the way to the Republic of Palau.
The Peek-a-Boo Club Takes Their First International Trip
The Palau Arc is a setting change the manga’s long-term readers have been waiting for. Iori, Kohei, Chisa, and the gang arrive in Palau for their first overseas diving adventure — with eccentric new faces, crystal-clear reef diving, and the kind of unhinged situations the show has always excelled at. Palau’s real-world reputation as one of the premier dive destinations on the planet makes it a fitting playground, and Season 3 looks to lean into the open-water, sun-drenched backdrop as a contrast to the university-town chaos of earlier seasons.
New Cast, New Music — Same Grand Blue Energy
Director Shinji Takamatsu returns alongside studios Zero-G and Liber. The core voice cast is back — Yuma Uchida as Iori, Ryohei Kimura as Kohei, and Chika Anzai as Chisa — joined by a strong lineup of newcomers for the Palau arc. Sayaka Ohara, Asami Seto, and Aya Suzaki take on key new roles, while M·A·O voices Carina, who looks set to make an impression as a standout character in the arc.
The opening theme is “Natsuko” by Funky Monkey Babys, while the ending “Hadaka no Mermaid” is performed by Mameshiba no Taigun — both acts that fit the show’s sun-soaked, high-energy mood perfectly.
How to Watch Grand Blue Dreaming Season 3 in Singapore
Season 3 is on Crunchyroll now, with new episodes every Monday at 8:30 AM Pacific Time — that is 11:30 PM SGT Monday nights, so Singapore fans can catch each episode late that evening. If you have not seen the earlier seasons, both Season 1 and Season 2 are already on Crunchyroll; the series is easy to dive into and rewards every episode. Crunchyroll is available in Singapore via web browser and mobile app.
Grand Blue has always thrived on cast chemistry and its commitment to absolute, loveable chaos — the Palau setting gives Season 3 a fresh sandbox without changing what makes it work. For more on what is streaming this anime season, see our anime coverage.
