The Hidden Dungeon Only I Can Enter Manga Volumes

The Hidden Dungeon Only I Can Enter Has 12 Manga Volumes — And the Series Is Complete

Here’s the short version: The Hidden Dungeon Only I Can Enter has 12 manga volumes in total, and the series is fully complete in both Japanese and English. No cliffhangers, no waiting for the next release — you can read the entire story from start to finish right now.

The manga is adapted from the light novel (a type of short, illustrated Japanese novel) by Meguru Seto (瀬戸メグル). The manga artwork is by Tomoyuki Hino (樋野友行), and the character designs — meaning the original visual look of each character that the manga artist works from — come from Takenote (竹花ノート). The English edition is published by Seven Seas Entertainment, a company that licenses and translates manga for English-speaking readers. All 12 volumes are available.

For readers who like to plan their purchases, this is a nice position to be in. You know exactly how many books you need, there won’t be any surprise delays or hiatuses, and you can pace your reading however you like.

Volume-by-Volume Overview

Here’s a look at all 12 volumes to give you a sense of how the story progresses. The manga was originally published in Japan and later translated into English, so each volume has two release windows. The table lists the “Japanese Release Window” — when the volume first came out in Japan — with the English editions from Seven Seas following later.

Volume	Japanese Release Window	What to Expect
Vol 1	December 2018	Noir discovers the hidden dungeon and gains the powerful Edit skill — this is your entry point
Vol 2	May 2019	Early dungeon exploration kicks off and the party starts to take shape
Vol 3	December 2019	Noir’s abilities expand as new challenges emerge
Vol 4	May 2020	Continues the dungeon exploration with new encounters and character development
Vol 5	December 2020	Mid-series escalation — stakes get higher and the scope of the story broadens
Vol 6	February 2021	New threats appear and relationships between characters deepen
Vol 7	June 2021	A turning-point storyline that shifts the direction of the narrative
Vol 8	November 2021	Consequences from the mid-series events start to play out
Vol 9	May 2022	The story begins building toward its final stretch
Vol 10	November 2022	Major confrontations raise the tension heading into the endgame
Vol 11	September 2023	Penultimate volume — sets up the pieces for the conclusion
Vol 12 (Final)	April 2024 (JP) / January 2025 (EN)	Series conclusion — wraps up the story completely

All 12 volumes are available in English from Seven Seas Entertainment, so you won’t hit a gap where only the Japanese edition exists. The final English volume (Vol 12) released on January 14, 2025, making the complete set fully accessible to English-speaking readers.

What Makes This Dungeon Fantasy Worth Reading

The Hidden Dungeon Only I Can Enter follows Noir, a low-ranking noble — someone born into the lowest tier of the aristocracy in a fantasy world, meaning he has a title but little power or money. He stumbles upon a legendary dungeon that nobody else can access. Inside, he gains an absurdly powerful ability called the Edit skill, which lets him create, modify, and grant skills to himself and others. In this world, characters have defined abilities (like spells or combat techniques) that function almost like upgradeable tools — and Noir can rewrite those abilities however he wants. It’s exactly as overpowered as it sounds, and that’s kind of the point.

If you enjoy stories where the main character has overwhelmingly strong abilities (often called “OP” or overpowered in manga fan circles) or dungeon-crawling fantasy — a subgenre where characters explore underground labyrinths full of monsters and treasure — this one fits right into that space. It’s not a traditional isekai (a genre where the main character is transported from our world into a fantasy world — Noir isn’t transported from anywhere; he’s always lived in his fantasy world), but it scratches a very similar itch. The dungeon exploration, skill-based power system, and fantasy setting will feel familiar to anyone who enjoys the genre.

The tone leans light and fun rather than dark or gritty. There’s a good amount of comedy, and the series features harem elements — a common manga storytelling convention where multiple romantic interests are attracted to the main character, played mostly for comedy and lighthearted romantic tension here rather than anything explicit. The fantasy action stays entertaining without getting too heavy. It’s the kind of series you pick up when you want something enjoyable and easy to read rather than something that’s going to put you through an emotional wringer.

There’s also an anime adaptation (a 12-episode TV series that aired in 2021), so if you’ve seen the show and want to continue the story or experience it in manga form, these 12 volumes cover the full narrative — well beyond where the anime ends.

Meguru Seto’s original light novel provides the story foundation, Tomoyuki Hino’s manga art brings the dungeon crawling and action sequences to life, and Takenote’s character designs give the cast a distinctive look that fans have responded well to. The collaboration works — the manga adaptation feels polished and complete as its own reading experience.

Who Will Enjoy This Most

• Readers who love watching an underdog gain ridiculous power and use it creatively
• Fans of dungeon-crawling fantasy with a lighter, comedic tone
• Anyone who enjoys romantic comedy with multiple love interests mixed into action and adventure
• People looking for a completed series they can binge from start to finish without waiting
• Anime viewers who want the full story beyond what the show covered

Who Might Want Something Different

• If you prefer darker, more serious dungeon fantasy, this might feel too lighthearted
• Readers who dislike multi-romance setups will find that element is pretty central here
• If you want complex world-building or political intrigue, this series keeps things more straightforward

Neither of those is a criticism — it’s just about matching the right series to the right reader.

Is the Manga Finished?

Yes — The Hidden Dungeon Only I Can Enter is fully complete at 12 volumes. This applies to both the Japanese and English editions, so there’s nothing lost in translation gaps or ongoing publication.

Here are the key dates:

• Japanese publication ran under Kodansha’s Sirius KC label, starting in December 2018
• The final Japanese volume (Vol 12) released in April 2024
• The final English volume (Vol 12) released on January 14, 2025 via Seven Seas Entertainment

There are no more volumes forthcoming. The story has a definitive ending, and you can read the entire thing now without worrying about cancellations, indefinite pauses, or being left on a cliffhanger.

This is actually one of the big advantages of picking up this series in 2026. When the manga was still running, readers had to wait months between volumes. Now you can grab the whole set and read at your own pace — whether that means powering through all 12 volumes in a weekend or spacing them out over a few weeks.

For collectors, a complete series is also nice because you know exactly what your shelf space commitment looks like. Twelve volumes is a very manageable set — not so short that it feels rushed, and not so long that it becomes a major investment to complete.

Where to Buy the English Manga

All 12 volumes are published by Seven Seas Entertainment and available through major retailers, including Amazon and various digital manga platforms.

Getting Started

If you’re not sure whether this series is for you, start with Volume 1 before committing to the full set. It introduces Noir, the hidden dungeon, and the Edit skill — so you’ll have a clear sense of the tone, art style, and storytelling approach within the first volume. That’s enough to know whether you want to continue.

The final volume wraps up the complete story, so once you’ve decided you’re in, you can confidently collect the whole run knowing it reaches a proper conclusion.

Format Options

Seven Seas offers the standard individual volume format for this series. There’s no confirmed omnibus edition (a single book that collects multiple volumes together), box set, or deluxe edition available as of early 2026. If that changes in the future, it would likely be announced through Seven Seas’ official channels.

The individual volumes are the way to go for now, and honestly, 12 volumes is a pretty comfortable number to collect one at a time or in small batches.

Building Your Collection

• Sample first — grab Volume 1 and see if the series clicks for you before buying multiple volumes at once
• Digital is an option — if shelf space is a concern, the digital editions let you read the full series without the physical footprint
• Watch for seasonal sales — manga volumes frequently see reduced pricing during big sale periods throughout the year, so patience can pay off if you’re collecting the whole set

Twelve volumes at standard manga pricing is a reasonable investment for a complete story. You’re getting a full beginning-to-end narrative with no filler or padding — just a fun dungeon fantasy from start to finish.
