What Gantz Is About (Spoiler-Free)
High schoolers Kei Kurono and Masaru Kato are killed in a subway accident. Instead of dying, they wake up in a bare Tokyo apartment alongside other recently deceased strangers. In the center of the room sits a large, mysterious black sphere — Gantz.
Gantz gives them high-tech suits and weapons, then teleports them to hunt aliens hidden in the real world. They have a time limit. If they survive the mission, they’re sent back to their normal lives until Gantz summons them again. If they die during a mission… they stay dead.
There’s a point system that drives the tension. Kill aliens, earn points. Rack up 100 points and you get a choice: earn your freedom from the game, get your memory wiped and walk away, or trade those points for a powerful weapon upgrade. That choice — and the desperate fight to reach it — fuels a huge amount of the drama.
What starts as small, contained alien hunts in Tokyo neighborhoods gradually escalates into something much, much bigger. By the final story arc (a named storyline segment within the larger series), the scope has expanded into full-scale existential conflict.
The tone is bleak, darkly humorous, and morally complicated — characters aren’t purely good or purely evil, and the story doesn’t reward you for rooting for anyone in particular. Characters you like will die. Characters you hate will survive. The protagonist starts out genuinely unlikable. Hiroya Oku, the series’ creator, isn’t interested in making you comfortable — he’s interested in seeing what happens when ordinary, flawed people are thrown into impossible situations.
How to Read Gantz Manga — Volumes and Arcs at a Glance
Gantz flows through a series of mission arcs, each named after the aliens the team is sent to fight. An “arc” is simply a storyline chunk — think of it like a season of a TV show, with a beginning, middle, and end within the larger series. Here’s the full breakdown so you always know where you are.
A quick note on terms: a chapter is a single installment of the story (usually around 20 pages), and a volume is a physical or digital book that collects several chapters together.
Phase 1 — Tokyo Missions (Vols 1–10)
This is the foundation. You’ll meet the core cast, learn the rules of the Gantz game (the point system and mission structure described above), and watch things get progressively more dangerous.
Onion Alien Arc — Chapters 1–27, Volumes 1–3
The introduction. Kurono and Kato arrive in the Gantz room, get thrown into their first mission, and learn just how lethal this game is. This arc sets the rules and the tone — expect confusion, panic, and a lot of death.
Tanaka Alien Arc — Chapters 28–56, Volumes 4–6
The stakes escalate fast. Team dynamics start to form (and fracture). New hunters arrive. The missions get harder, and the emotional cost gets steeper.
Buddhist Temple Alien Arc — Chapters 57–90, Volumes 7–10
This is where Gantz really shows its teeth. Major casualties, gut-punch moments, and some of the most intense action sequences in the early series. If you’re not hooked by the end of this arc, the series probably isn’t for you.
Note: This is roughly where the anime (the animated TV adaptation, 26 episodes) ends — though the anime diverges significantly from the manga and has its own original ending that doesn’t appear in the source manga. More on that below.
Phase 2 — Escalation (Vols 11–17)
The world of Gantz expands well beyond the original Tokyo apartment.
Shorty Alien / Kill Kei Kurono Arc — Chapters 91–111, Volumes 11–13
A tonal shift. The world gets bigger, the threats get stranger, and the story starts asking new questions about what Gantz actually is.
Dinosaur Alien Arc — Chapters 112–151, Volumes 13–17
The longest hunt yet at this point in the series. New characters join the team, the setpieces get massive, and the fight sequences are some of Oku’s best — panel layouts that feel almost cinematic in how they capture motion and impact. This arc is a major escalation in both scale and emotional investment.
Phase 3 — Osaka and Beyond (Vols 16–25)
This is where many readers say Gantz peaks.
Ring Alien Arc — Chapters 152–174, Volumes 16–19
A relative breather before the chaos — though “breather” is relative when we’re talking about Gantz. Important character development happens here.
Osaka / Nurarihyon Arc — Chapters 175–237, Volumes 19–25
Multiple Gantz teams from across Japan converge on Osaka for a massive, multi-team battle against some of the most powerful aliens in the series. (Nurarihyon is the name of the alien boss they’re sent to fight — a figure from Japanese folklore reimagined as a terrifying enemy.) This arc is widely considered the high point of Gantz — the action is relentless, the stakes are sky-high, and the scale is genuinely breathtaking.
This is also the arc adapted by the GANTZ:O computer-animated film released in 2016.
Phase 4 — Endgame (Vols 26–37)
Everything goes global.
Italy / Katastrophe Arc — Chapters 238–279, Volumes 26–30
The alien threat goes worldwide. The scope expands beyond anything the earlier arcs hinted at. The rules of the game change dramatically.
Invasion Arc — Chapters 280–383, Volumes 30–37
The final arc. Full-scale war. Resolution — of a kind.
A note on the ending: it’s divisive. Some readers love it, some feel it’s rushed or unsatisfying. Going in with that expectation will serve you better than expecting a perfectly neat conclusion. The journey is absolutely worth it regardless.
Here’s a quick reference table for the full arc breakdown:
| Arc | Chapters | Volumes | Phase |
|---|---|---|---|
| Onion Alien | 1–27 | 1–3 | Phase 1: Tokyo Missions |
| Tanaka Alien | 28–56 | 4–6 | Phase 1: Tokyo Missions |
| Buddhist Temple Alien | 57–90 | 7–10 | Phase 1: Tokyo Missions |
| Shorty Alien / Kill Kei Kurono | 91–111 | 11–13 | Phase 2: Escalation |
| Dinosaur Alien | 112–151 | 13–17 | Phase 2: Escalation |
| Ring Alien | 152–174 | 16–19 | Phase 3: Osaka & Beyond |
| Osaka / Nurarihyon | 175–237 | 19–25 | Phase 3: Osaka & Beyond |
| Italy / Katastrophe | 238–279 | 26–30 | Phase 4: Endgame |
| Invasion | 280–383 | 30–37 | Phase 4: Endgame |
Omnibus vs. Single Volumes — Which Edition to Buy
You’ve got three main options for reading Gantz in English. Here’s how they compare:
| Format | Volumes | Pages Per Book | Availability | Best For |
|---|---|---|---|---|
| Dark Horse Omnibus | 12 books | ~600 pages each (3 original vols per omnibus) | Currently in print and widely available | Physical collectors who want good value |
| Dark Horse Singles | 37 books | Standard manga length (~200 pages) | Many out of print (no longer being produced, so only available secondhand at higher prices) | Collectors who want the original single-volume format |
| Digital (Kindle) | 37 individual volumes | Standard manga length | All available, instant access | Budget readers and anyone who prefers screens |
Dark Horse Comics is the American publisher that handles the English-language release of Gantz. Their omnibus editions are the way to go for most people. Each one collects three original volumes into a thick ~600-page book, so you only need 12 books to own the entire series. They’re currently in print, and you can find them at major bookstores and online retailers.
The single-volume editions (37 total) were published by Dark Horse over many years. A lot of them are now out of print, which means you’ll be paying inflated secondhand prices for some volumes. Unless you specifically want the singles format, the omnibuses are a much better deal.
Digital is the cheapest option overall. All 37 volumes are available on Kindle (Amazon’s digital reading platform), so you can start reading immediately without waiting for shipping. If budget is your main concern or you just prefer reading on a tablet or phone, digital is the move.
Honestly, just grab Omnibus Vol. 1 and see if the first three volumes hook you. If they do, you’re in for one of the wildest rides in manga.
One more note for first-time manga readers: manga is read right-to-left, both in terms of page order and panel order. When you open the book, start from what would be the “back” of an English book. The publisher includes a guide on the first page explaining this, so don’t worry — you’ll pick it up quickly.
Coming from the Anime or GANTZ:O? Where to Pick Up
If You Watched the Anime (26 Episodes)
The Gantz anime loosely covers Volumes 1–10 of the manga, but here’s the thing — it diverges significantly and has a completely original ending that was created specifically for the TV show and doesn’t exist in the manga.
The strongest recommendation is to start reading from Volume 1. The manga experience is substantially different from the anime, and you’ll get the full version of events that the anime condensed or rewrote.
If you really don’t want to re-cover familiar ground, you could start at Volume 11, which picks up after the manga chapters the anime was based on. Just be aware that some characters were handled differently in the anime — a few manga-only characters won’t have been introduced to you, and certain plot threads were resolved differently. You won’t be completely lost, but you’ll occasionally wonder “wait, who is that?” for the first few chapters. Starting from Volume 1 avoids all of this.
If You Watched GANTZ:O (2016 Film)
GANTZ:O is a computer-animated film that adapts the Osaka / Nurarihyon Arc, which corresponds to approximately Volumes 19–25. It’s a fantastic-looking film, but it drops you into the middle of the story — there are over 170 chapters of character development, story foundations, and escalation before that arc begins.
Start from Volume 1 for the full experience. If you absolutely want to skip ahead to the Osaka buildup, Volume 16 (the Ring Alien Arc) is the minimum starting point to understand what’s happening and who these characters are.
But seriously — start from the beginning. The buildup is what makes the Osaka arc hit so hard.
Gantz Spinoffs — Do You Need Them?
A spinoff is a separate story set in the same fictional universe, usually with different characters and its own self-contained plot. Gantz has two, and neither is required to understand the main series. Both are worth checking out after you finish.
Gantz:G (3 Volumes, Complete)
A separate cast of characters operating in the same Gantz universe. It’s a self-contained story — beginning, middle, and end all within three volumes — that plays with the Gantz mechanics in a fresh setting. A quick read. Save it for after you finish the main series — it’s more fun with full context.
Gantz:E (8 Volumes, Ongoing in Japanese)
This one’s set in the Edo period — a historical era in Japan (roughly 1603–1868) defined by samurai culture and feudal rule — with Gantz technology dropped into that setting. It’s a standalone story with its own characters and plot.
There’s no official English edition as of 2026 — Gantz:E is currently available only in Japanese, serialized on Shueisha’s YanJan! app. Again, read the main series first — you’ll appreciate the concept much more.
Content Warnings and Who Gantz Is For
This section is important reading before you buy. Gantz is one of the most graphically intense manga widely available in English, and it’s worth knowing exactly what you’re getting into.
What to Expect
- Extreme gore: Dismemberment, decapitation, exposed internal organs — depicted in detailed, realistic art. Some of the most graphic violence in manga, period.
- Sexual content: Frequent nudity, explicit scenes, and sexual violence. Oku doesn’t shy away from any of it.
- Dark themes: Meaningless death, moral ambiguity, a general sense that the universe doesn’t care about its characters. Major characters die without warning or fanfare. The story doesn’t soften its punches.
- Uncomfortable protagonist: Kurono starts the series as a selfish, cowardly, often creepy teenager. His growth is a core part of the story, but the early volumes can be rough.
Who Will Love This
If you enjoy horror and sci-fi manga that pushes boundaries, Gantz is right in your wheelhouse. Fans of Berserk (a dark fantasy manga about a lone warrior in a brutal medieval world), Attack on Titan (a series about humanity fighting for survival against giant humanoid creatures), or any story with high stakes and a willingness to kill off major characters will find a lot to love here.
It’s also a great pick if you love sci-fi action with a horror edge. The alien designs get increasingly creative and terrifying, and the fight sequences are genuinely spectacular — Oku’s art is detailed and cinematic in a way that few manga artists match.
Who Might Want to Skip This
- Readers sensitive to sexual violence — it appears multiple times and is depicted graphically
- Readers who need likable protagonists from page one
- Anyone looking for a light or feel-good read
There’s no shame in deciding Gantz isn’t for you. Manga is huge — there are plenty of great horror and sci-fi titles that don’t go as far as Gantz does.
Getting Started — Your First Purchase
Ready to jump in? Here’s the simplest path:
- Physical reader: Pick up Gantz Omnibus Vol. 1 — it collects the first three volumes (Chapters 1–27, the entire Onion Alien Arc) in one thick book. That first arc is a complete introduction to the world, the rules, and the tone. If you finish it and want more, keep going with Omnibus Vol. 2.
Gantz Omnibus Vol.1
- Digital reader: Grab Volume 1 on Kindle. It’s the cheapest possible entry point, and you can buy volumes one at a time as you go.
- Already hooked and want to read everything: The omnibus editions are your best friend. Twelve books, the whole series, done.
Frequently Asked Questions
How many volumes is Gantz?
37 individual volumes, or 12 omnibus editions that collect the entire series.
Where does the Gantz anime end in the manga?
The anime roughly covers Volumes 1–10 (the Buddhist Temple Alien Arc), but it diverges significantly and has its own original ending. The manga continues for 27 more volumes after that point.
Is there a box set for Gantz?
There’s no official box set. The 12-volume omnibus series from Dark Horse is the most practical way to collect the full manga.
Gantz is intense, polarizing, and unlike almost anything else in manga. It’s not going to be for everyone — but if it clicks with you, you’ll tear through all 37 volumes wondering why you didn’t start sooner.
