Imagine a crew of college dudes diving headfirst into a club that’s less about scuba gear and more about epic, booze-fueled chaos. That’s Grand Blue Dreaming, the manga that’s been a riot since 2014, blending crude humor with those raw, real moments of friendship. The anime’s first season hit in 2018, leaving fans parched for more. After a seven-year wait, Season 2 finally dropped in July 2025, serving up 12 episodes of pure hilarity. Then, right as the finale aired on September 22, 2025, the big news landed: Season 3 is officially coming. The internet went wild, and honestly, it’s hard not to vibe with that excitement—this show captures the messy, hilarious spirit of young adulthood like no other. For those itching to know what’s next, here’s the full scoop on Grand Blue Season 3.
Grand Blue Dreaming Season 3 Release Date Speculations
No hard lock yet on the exact premiere, but the patterns from past seasons give some solid clues. Season 2 got announced in September 2024 and rolled out just nine months later in July 2025. With Season 3 greenlit on September 22, 2025—literally hours after the Season 2 closer—folks are buzzing about a similar timeline. That points to a potential drop in summer or fall 2026, maybe even July to keep that sunny, beachy energy flowing.
Grand Blue Dreaming Season 3 Expected Cast
The voice cast for Grand Blue is a powerhouse, nailing every awkward, over-the-top moment. No new names confirmed for Season 3 yet, but the core squad from the first two seasons is set to return. Shinji Takamatsu’s back as director and writer, keeping the absurd timing on point. Hideoki Kusama’s handling character designs again, ensuring those wild expressions pop off the screen.
Here’s who’s voicing the main crew:
-
Iori Kitahara (Yuma Uchida): The dreamer who’s always one step from disaster—Uchida’s knack for panicked everyman energy is gold.
-
Kohei Imamura (Ryohei Kimura): The sly best friend with a soft side; Kimura’s voice drips with just the right mischief.
-
Chisa Kotegawa (Chika Anzai): The level-headed diver girl who reins in the chaos—Anzai’s cool vibe balances the madness.
-
Shinji Tokita (Hiroki Yasumoto): The beefy club vet with a voice like thunder—Yasumoto makes every line a scene-stealer.
-
Ryuji Azusawa (Katsuyuki Konishi): Peek-a-Boo’s loose cannon; Konishi’s charm keeps the crazy relatable.
Side characters like Azusa Hamaoka (Aoi Yuki) and Kenta Fujii (Nobuhiko Okamoto) add extra spice, and there’s buzz about new voices joining for Season 3’s big trip. Music-wise, Shōnan no Kaze set the tone with Season 1’s opening and collabed with Atarashii Gakko! for Season 2’s “Seishun Towa.” Expect another reggae-tinged banger to match the island vibes.
Grand Blue Dreaming Season 3 Potential Plot
Grand Blue nails that mix of diving goals and total derailment, and Season 3’s taking it global with a trip to Palau’s crystal waters. Season 2 closed out the Iori’s house arc, so the story’s primed to jump into the manga’s Palau chapters, where the Peek-a-Boo crew chases diving certifications but ends up in classic, unhinged antics.
Picture sun-drenched beaches meeting the gang’s signature strip-downs and schemes. Iori’s still the awkward anime nerd dodging pranks from Imamura and the boys. But Palau shakes things up with a new face: Sayaka Kotegawa, the sharp-witted manager of the local Dolphin branch. She’s Iori’s aunt (Toshio’s wife) and mom to Chisa and Nanaka, ready to either tame the chaos or make it worse. Whispers of other local characters joining the mix hint at some cross-cultural hilarity, turning dive trips into glorious messes.
The teaser visual keeps it real with that cheeky Grand Blue humor—Iori and Chisa front and center, probably mortified. Expect more of the show’s bold style: naked wrestling, beer-fueled diplomacy, and those bro moments that hit deep. With the manga at 25 volumes by October 2025, there’s plenty of story to adapt without rushing.
