Grand Blue Dreaming Manga Volumes: Full Guide (2026)

Grand Blue Dreaming currently has 26 manga volumes in Japan and 23 in English — and the series is still ongoing. If you’re here trying to figure out how many volumes exist, where the English release stands, and whether it’s worth jumping in, you’re in the right place. No prior knowledge of diving (or manga, for that matter) is required to enjoy this series.

For anyone brand new to the format: manga are Japanese comics published as individual chapters in magazines, then collected into book-sized volumes — typically around 180–200 pages each. Those collected volumes are what you buy and read. A sports manga is simply a manga where a sport plays a central role in the story, though as you’ll see with Grand Blue Dreaming, that label can stretch to cover some wonderfully unexpected territory.

Let’s break it all down.

Grand Blue Dreaming Has 26 Manga Volumes in Japan and 23 in English — Still Ongoing

Here’s the quick-reference snapshot before we go deeper:

Detail	Status
Japanese volumes	26 (latest released April 2026)
English volumes	23
Serialization	Ongoing in good! Afternoon
First JP volume	November 2014
Series status	Still running — no announced end date

Written by Kenji Inoue with art by Kimitake Yoshioka, Grand Blue Dreaming (ぐらんぶる) has been serialized — meaning its chapters are published on a regular schedule — in Kodansha’s good! Afternoon magazine (a Japanese manga anthology) since 2014. The Japanese publisher is Kodansha, and the English edition is also published under the Kodansha umbrella, which generally means consistent translation quality and reliable release scheduling.

The English edition currently trails Japan by several volumes, which is standard for manga published in translation. New English volumes have been releasing steadily, so the gap isn’t growing — it’s the natural lag of the translation and adaptation process. Volume 23 in English was released in December 2025, and given Kodansha’s consistent publishing pace, readers can expect the gap to continue closing at a steady rate.

At its core, the story follows Iori Kitahara, a college freshman who moves to a coastal town to attend university. He ends up living above his uncle’s scuba diving shop, Grand Blue, and gets roped into the Peek-a-Boo diving club. What follows is a chaotic mix of outrageous college humor, surprisingly detailed scuba diving content, and a cast of characters who are all varying degrees of unhinged.

If you’ve ever wondered what would happen if you crossed a sports manga with a raunchy college comedy, this is the answer — and it works way better than it has any right to.

Key Grand Blue Dreaming Manga Volumes at a Glance

With 23 English volumes available, here’s a look at milestone points across the series to give you a sense of where the story goes. No major spoilers — just enough to orient you and help you decide what to pick up.

Volume(s)	What Happens	Comedy-to-Diving Ratio
Vol 1	Iori joins Peek-a-Boo diving club; tone and cast established	~90/10
Vols 2–5	College chaos; diving certification begins	~80/20
Vols 6–12	Certification storylines take center stage; ocean diving trips	~60/40
Vols 13–20	Cast expands; character relationships deepen; diving becomes co-equal	~50/50
Vols 21–23	Current English endpoint; story threads still active	~50/50

Volume 1 — Where It All Begins

Volume 1 sets the tone immediately. Iori arrives at a university on the Izu Peninsula expecting a normal college life, and within the first chapter, he’s dragged into the Peek-a-Boo diving club’s particular brand of chaos. The club members are more interested in drinking games than actual diving — at first. This volume establishes the core cast, the comedy style (physical, absurd, and fully committed), and drops the first hints that there’s more to Grand Blue than just gags. If you’re going to read one volume to decide whether this series is for you, this is it.

Volumes 2–5 — Finding the Rhythm

The early stretch of Grand Blue Dreaming leans heavily into comedy. Iori’s attempts to have a “normal” college experience get sabotaged repeatedly by the diving club members, his cousin Chisa (who actually takes diving seriously), and his own terrible decision-making. But scattered through the chaos, diving starts to take root as a real thread. Certification processes come up, and you start to see Iori’s reluctant but growing interest in the sport. The comedy-to-diving ratio here is maybe 80/20 — and that’s fine, because the comedy is excellent.

Volumes 6–12 — Diving Takes Center Stage

Starting around Volume 6, something shifts. The diving certification storylines — meaning multi-chapter sequences focused on training and qualification — become more prominent, and the manga starts spending real page time on training, equipment, and what it actually feels like to be underwater. Volumes in this range include ocean diving trips that showcase the sport beautifully, with Yoshioka’s art shining in underwater sequences. The comedy doesn’t go anywhere (this series will never stop being ridiculous), but the balance starts tilting toward something more like 60/40 comedy-to-diving. Readers who came purely for the laughs often find themselves genuinely interested in scuba diving by this point.

Volumes 13–20 — Expanded Cast, Deeper Stories

As the series moves into these later volumes, the cast expands and individual storylines get more room to breathe. Relationships between characters deepen, rivalries get more nuanced, and the diving content becomes increasingly detailed and well-researched. The series does a great job of making you care about characters who started as simple comic-relief figures. There’s real emotional weight buried under the slapstick, and it sneaks up on you.

Volumes 21–23 — The Current English Endpoint

Volume 23, released December 2, 2025, is the most recent English release, marking the current stopping point for readers following the official English translation. With Japan at volume 26, there’s still a gap to close — and given that the series is ongoing, more volumes are on the way. If you’re the type who prefers to wait for a completed series, Grand Blue Dreaming isn’t there yet. But if you’re okay with catching up and then waiting for new releases, 23 volumes is a very satisfying amount of content to work through.

The Comedy-to-Diving Shift

One thing worth noting across the full run: the series evolves. Early volumes are comedy-dominant with diving as a backdrop. Later volumes still bring the laughs, but diving becomes a co-equal pillar of the story. This isn’t a sudden switch in tone — the comedy never disappears. It’s more like watching a friend who started diving as a joke slowly fall in love with it for real. If you’re coming to Grand Blue Dreaming specifically for its sports manga side, stick with it past the early volumes. The diving payoff is real.

How Real Is the Diving in Grand Blue Dreaming?

This is the question that surprises people. Grand Blue Dreaming has a reputation as a drinking manga with diving as window dressing — and honestly, the first few volumes lean into that perception. But the diving content is legitimately well-researched and presented with care. This matters for your buying decision because it’s the diving that gives the series its long-term staying power.

Certification and Training

The manga walks through recreational scuba diving certification in a way that’s both entertaining and informative. Characters study theory, practice skills, and deal with the real anxieties of learning to breathe underwater. The process isn’t glossed over or played purely for laughs — there’s genuine respect for what it takes to become a certified diver. Readers who’ve gone through certification themselves often comment on how accurate the depictions are.

Equipment and Technique

Regulators (the mouthpiece device that delivers air from your tank), BCDs (buoyancy control devices — inflatable vests that help divers float or sink), wetsuits, weight belts — the gear shows up and gets explained naturally through the story. Yoshioka draws equipment with enough detail that you can tell the difference between setups, and the manga doesn’t shy away from practical details like clearing a flooded mask or equalizing pressure during descent. It’s not a technical manual, but it’s way more than most manga would bother with.

Underwater Scenes

This is where the art truly elevates the series. Yoshioka’s underwater panels are gorgeous — the sense of light, depth, and weightlessness comes through beautifully. The contrast between the chaotic above-water comedy and the serene underwater sequences is one of Grand Blue Dreaming’s greatest strengths. These scenes genuinely capture what draws people to diving: that feeling of entering a completely different world.

You Don’t Need Diving Knowledge to Enjoy This

Here’s the good news for anyone hesitating: you don’t need to know anything about scuba diving to enjoy Grand Blue Dreaming. The manga teaches you what you need to know alongside the characters. What makes it work as a sports manga — a manga built around a sport — is that it makes you care about an activity you might never have considered. Readers regularly report that the series sparked a genuine interest in scuba diving, which is one of the best compliments a sports manga can receive.

Is the Series Finished or Still Running?

Grand Blue Dreaming is still ongoing. It continues to be serialized in Kodansha’s good! Afternoon magazine, with no announced end date.

The series has been running for over a decade now, which puts it in the category of long-running manga that have found a sustainable rhythm. New Japanese volumes have been releasing regularly, and the English translation has maintained a steady pace behind them.

The Anime Connection

The manga has been adapted into a multi-season anime (a TV show based on the manga) that has introduced many viewers to the series. Season 1 aired in 2018, Season 2 in 2025, and Season 3 premiered in July 2026 and is currently airing. Even with three seasons, the anime covers only a portion of the manga’s story, so anime fans who want more will find plenty of additional content in the volumes. The show tends to drive waves of new manga readers with each new season, so if you’re coming from the anime — welcome, and know that the manga goes much further.

What About Catching Up?

With 23 English volumes available, catching up is a meaningful commitment — but a rewarding one. The volumes are fairly quick reads thanks to the comedy pacing, so you can move through them faster than you might expect. Many readers report binging the series in a matter of days because it’s genuinely hard to put down.

If you prefer waiting for a series to finish before starting, that’s completely valid — but there’s no indication the end is imminent. The story still has active threads and the serialization shows no signs of wrapping up soon.

Where to Buy Grand Blue Dreaming Manga Volumes in English

The English edition of Grand Blue Dreaming is published by Kodansha and is widely available in both print and digital formats.

Format Options

As of now, the standard single-volume format is the only confirmed English edition. There are no omnibus editions (multiple volumes collected into one larger book), deluxe editions (premium printings with extras), or box sets that have been announced. Each volume corresponds to one Japanese collected volume, which keeps things straightforward — volume 1 in English matches volume 1 in Japanese, and so on.

Where to Find Them

Grand Blue Dreaming volumes are available through major online and physical retailers. Bookstores that carry manga will typically have at least the first several volumes in stock, and the full range is available through online sellers. Digital versions are also available through Kodansha’s platforms and major e-book retailers, which is a great option if you want to start reading immediately or prefer not to store physical volumes.

Buying Tips

• Start with Volume 1. The series is best read from the beginning — there’s no recommended skip-ahead point, and the character dynamics build gradually.
• Digital is convenient for sampling. If you’re unsure whether the series is for you, grabbing a digital copy of Volume 1 is a low-commitment way to find out.
• Physical volumes look great on a shelf. The cover art is consistently eye-catching, with Yoshioka’s clean character designs popping against ocean-blue backgrounds.
• Check retail prices before buying. Kodansha’s standard manga volumes have a set list price (sometimes labeled MSRP, or Manufacturer’s Suggested Retail Price) — knowing that number helps you recognize a fair deal when you see one.

A Note on the 23-Volume Commitment

Twenty-three volumes might sound like a lot, but consider this: the comedy pacing means each volume reads quickly, the page count per volume is standard for manga (around 180–200 pages), and the series rewards binge-reading in a way that slower-paced manga sometimes don’t. You’ll know within the first volume whether this series clicks for you — and if it does, you’ll be glad there are so many more waiting.

Grand Blue Dreaming is one of those rare series that genuinely earns its dual identity. It’s a hilarious college comedy AND a heartfelt sports manga about falling in love with diving. If that combination sounds even remotely appealing to you, pick up Volume 1 and see for yourself. You’ll probably be laughing before you finish the first chapter — and thinking about scuba lessons by volume 10.
