A diving manga that spends most of its time absolutely not diving
On paper, Grand Blue Dreaming sounds like a chill college manga about scuba diving. Iori Kitahara moves to Izu to begin life as a mechanical engineering student, stays at his uncle's diving shop near campus, and ends up pulled into the orbit of the Peekaboo Diving Club.
Then the actual series kicks in: wild parties, dangerous university experiments, naked comedy, friends who behave like enemies, and enough drinking jokes to make you wonder how anyone in this club still passes class.
Anime News Network's review of Volumes 1-23 frames the manga as less of a heartfelt ocean adventure and more of a long-running university chaos machine. Yes, there is actual scuba diving. Yes, the manga clearly cares about the beauty of the sea. But the main flavour is very much drunken stupidity, loud insults, and bros making terrible decisions together.
What the manga is really selling
The setup is simple: Iori wants a fresh start at technical college, but the diving club basically hijacks his life. His days include bizarre lessons and risky experiments, while his nights are swallowed by club parties and social disasters.
The review points out that Grand Blue Dreaming is not the kind of manga you read for deep emotional plotting. There is character growth across 23 volumes, and some genuine conversations do happen, but those moments usually get buried under comedy. The series' biggest weapon is its willingness to be stupid at full volume.
That can be fun, especially if you enjoy that university-era humour where everyone is broke, horny, dramatic, and constantly sabotaging each other. But it can also be exhausting if you want emotional payoff without a gag crashing into the scene five seconds later.
The diving part still works, surprisingly
The most interesting thing is that the scuba content still lands. The manga shows diving trips to places like Okinawa and Palau, including scenes involving sharks, teamwork, leadership, and the thrill of exploring underwater spaces.
For Malaysian and SEA readers, this is probably the part that hits differently. We live in a region where diving is not some faraway fantasy. Sabah, Tioman, Perhentian, Redang, Sipadan energy — the ocean is part of the culture here. So when the manga actually slows down and lets the club enjoy diving, it can genuinely make you want to book a trip or finally take that diving certification seriously.
The problem is that these sincere diving moments often get drowned by the next drinking gag. The review describes that push-pull clearly: the ocean scenes are appealing, but the manga keeps dragging the reader back to alcohol-fuelled chaos.
Comedy that depends heavily on tolerance
Iori himself is described as a fairly standard average-guy manga lead: decent when sober, painfully awkward around women, and often reduced to embarrassing horny comedy. The surrounding cast is also messy, loud, and intentionally ridiculous.
One point in the manga's favour is that the club dynamic is not presented as one-sided. The women are allowed to be just as chaotic, crude, and confrontational as the men. Everyone insults everyone. Everyone is kind of terrible. The tone is broad and dumb rather than cruel, though the review still flags uncomfortable material including sexual harassment, implied nudity, violence, and extreme drinking.
Visually, the manga leans into exaggerated ugly faces and overdrawn reaction shots for jokes. That style can be funny in bursts, but across 23 volumes, especially if binged quickly, it apparently becomes a lot.
Should SEA fans check it out?
If you like university chaos comedy, ridiculous friend groups, and manga that treats maturity as an optional side quest, Grand Blue Dreaming may still be a strong pick. It has enough diving passion to avoid being a total bait-and-switch, and the club's adventures can be genuinely charming when they stop poisoning each other with bad decisions.
But if you want a clean sports-style diving story, or a romance/comedy with consistent emotional development, this one might test your patience. The review makes it clear: this series punishes anyone trying to take it too seriously.
Best advice? Do not binge 23 volumes in one shot, bro. Read it in smaller doses, enjoy the underwater bits, laugh when the jokes land, and know exactly what kind of chaos you are signing up for.
