My Monster Secret Manga: All 22 Volumes Guide (2026)

My Monster Secret Has 22 Manga Volumes — Here’s What a Complete Set Looks Like

My Monster Secret (実は私は, Jitsu wa Watashi wa) is a completed manga series by Eiji Masuda. It runs 22 volumes in both the original Japanese and the English edition, and every single one is available right now. No waiting, no missing pieces, no “Volume 14 is out of print forever” heartbreak. The whole thing is done. If you’re researching My Monster Secret manga volumes to figure out what collecting the full set involves, this guide covers everything you need.

The English edition comes from Seven Seas Entertainment, an American publisher that licenses and translates manga into English, in both print and digital formats. The series originally ran in Weekly Shonen Champion — a weekly Japanese manga anthology magazine — published by Akita Shoten in Japan. (“Shonen” roughly means “aimed at boys/teens,” though the series appeals well beyond that demographic.)

So what’s it about? Asahi Kuromine is a high school student with one fatal flaw: he cannot keep a secret. Not even a little. So when he discovers that his crush, Youko Shiragami, is actually a vampire, things get complicated fast. If anyone else finds out, Youko has to leave school. Asahi has to protect her secret — which would be challenging for a normal person, let alone someone whose face broadcasts every thought he’s ever had.

And vampires are just the start. The cast expands to include aliens, werewolves, demons, time travelers, and more. It’s a supernatural romantic comedy with a huge cast of characters and a genuinely funny sense of escalation. Each new character brings a new secret, and Asahi’s life gets exponentially more chaotic. The humor comes from mixing monster and sci-fi tropes with high school romance — think vampires sharing lunch periods and aliens hiding spaceships in the gym storage room.

The series carries a 13+ rating, making it accessible for younger readers and manga newcomers alike. The comedy is broad and warm, the romance builds naturally across the full run, and there’s a real emotional payoff waiting at the end. If you like supernatural comedy mixed with genuine romance, this is an easy recommendation.

The Easiest Way to Collect All 22 My Monster Secret Manga Volumes

There are no omnibus editions (collected multi-volume books), no box sets, and no special collected formats for My Monster Secret as of this writing. Collecting the series means picking up 22 individual volumes, one at a time or in batches.

That gives you two paths:

Print Collection

Twenty-two standard manga volumes on your shelf. It’s a satisfying row — long enough to feel like a real collection, short enough that it won’t consume an entire bookcase. Each volume is a standard Seven Seas single, so they’re uniform in size and spine design.

The English run wrapped up in late 2020, which means these volumes have been on the market for several years. Most should be available through major online retailers and bookstores, though some individual volumes may occasionally be temporarily unavailable while the publisher produces a new batch of copies. More on that in the availability section below.

For budgeting purposes, you’re looking at 22 volumes at typical manga single-volume retail pricing. No shortcuts through collected editions here — it’s the full 22 or nothing.

Digital Collection

Digital is the most reliable path to a complete set, full stop. No stock issues, no hunting for that one volume your local shop doesn’t carry, no worrying about condition. Every volume is available digitally through major ebook platforms, and they’ll stay available.

If you’re primarily a reader rather than a collector — meaning you care more about the story than having physical books on a shelf — digital gets you there with zero friction. You can also mix and match: buy your favorites in print, fill gaps digitally.

Key Volumes Worth Knowing About

Reading order for My Monster Secret is completely straightforward: Volumes 1 through 22, in sequence. No spin-offs, no side stories, no alternate reading paths to worry about. Start at Volume 1, finish at Volume 22, done.

That said, here are the volumes that mark important shifts in the series. You’ll read through all of them in order — these are just moments to look forward to as you go:

Volume 1 — Where It All Begins

This is the hook. Asahi discovers Youko’s secret, and the core dynamic of the entire series snaps into place. You’ll know within the first few chapters whether this manga’s comedy style works for you. The good news: Masuda’s comedic timing is sharp from the very first volume, and the central relationship between Asahi and Youko clicks right away. If Volume 1 makes you laugh, the series only gets better from here.

Volume 1 is widely available in both print and digital, so getting started is straightforward.

Volume 6 — The Cast Hits Critical Mass

By this point, the supporting cast has expanded significantly, and the comedy formula really finds its groove. The series shifts from “Asahi protecting one secret” to “Asahi drowning in everyone’s secrets,” and the interactions between characters start generating their own comedy independent of the main pair. This is where a lot of readers go from “this is fun” to “I need to read all of this.”

Volume 11 — The Midpoint Turn

Right around the halfway mark, the series starts threading longer storylines — multi-chapter plots with their own beginnings and endings — through the comedy. The jokes don’t stop — this is still very much a comedy — but there’s more connective tissue between chapters, and character relationships start developing in ways that carry real weight. If you’ve been reading purely for the laughs, this is where the story starts giving you reasons to care beyond the next punchline.

Volume 18 — The Endgame Begins

Stakes escalate. Story threads that have been building for volumes start converging. The balance shifts noticeably toward the series’ larger narrative without abandoning the comedy that got you here. This is the “okay, I’m not putting this down until it’s finished” volume for most readers.

Volume 22 — The Finale

The final volume, published in English on December 22, 2020. Everything wraps up here — the romance, the secrets, the sprawling cast, all of it. Without spoiling anything: the ending is satisfying. Masuda clearly planned how to land this story, and it shows. Twenty-two volumes of setup and the conclusion delivers.

Print Availability and What to Watch For

My Monster Secret’s English run is a few years old now, and Seven Seas titles from this era can sometimes go temporarily unavailable on individual volumes while the publisher produces a new batch of copies. The series as a whole hasn’t gone out of print, but that doesn’t mean every single volume will be sitting on every retailer’s shelf at any given moment.

A few things to keep in mind:

• Earlier volumes (roughly the first third of the series) were released first and have been on the market longest. These are the ones most likely to occasionally be temporarily unavailable in print from major retailers.

• No special editions or reprints are known as of this writing. The standard Seven Seas single-volume format is the only English print edition that exists.

• Check multiple retailers if a specific volume shows as unavailable at one. Stock often varies between online bookstores and local shops, and a volume that’s out at one retailer may be sitting on shelves at another.

• Digital editions are the safest fallback for any print volume that’s proving difficult to track down. Every volume is available digitally, so you’re never truly stuck.

• If you’re building a print set, it’s worth buying volumes as you find them rather than waiting to purchase everything at once. This avoids the frustration of having 21 volumes and needing to hunt for the one that happened to go temporarily unavailable while you were waiting.

The used market (secondhand bookstores, online resellers) is also an option for any stubborn gaps, though prices from individual sellers can vary widely.

A Finished Collection That Stays Finished

One of the best things about collecting My Monster Secret is the certainty. The series is fully complete. There is no continuation. No sequel. No “Part 2” announcement lurking out there. No additional volumes are coming. When you own all 22 volumes, you own the entire story, permanently.

For readers who’ve been burned by ongoing series that go on hiatus or manga that gets cancelled without a proper ending — this isn’t that. My Monster Secret ran its full course and concluded on its own terms.

Want More from Eiji Masuda?

If you finish all 22 volumes and want to see what Masuda did next, a related work called Yumemigaoka Wonderland exists. It’s a separate series — not a continuation or a story set in the same world — but it comes from the same creator. It won’t add to your My Monster Secret collection, but it’s worth knowing about if you enjoy Masuda’s style.

The Anime Adaptation

A TV anime adaptation aired starting in July 2015 for anyone who wants to experience the story in animated form. The anime covers a portion of the manga’s story — manga series frequently contain far more story than their anime adaptations have time to cover, and My Monster Secret is no exception. The manga goes significantly further than the anime does.

If you’ve already seen the anime and are wondering whether to read the manga: starting from Volume 1 is the recommended approach. The manga’s comedy and storytelling have nuances the anime couldn’t fully capture, and you’ll get the most out of the later volumes by reading the full series from the beginning. Either way, the manga’s 22 volumes contain the complete story that the anime only begins to tell.

Shelf Commitment

At 22 volumes, My Monster Secret sits in a comfortable sweet spot for collectors. It’s long enough to tell a complete, satisfying story with real character development and multi-chapter storylines. It’s short enough that the commitment doesn’t feel overwhelming — you’re looking at roughly two shelf-lengths of standard manga volumes, not an entire bookcase. For someone building their first manga collection, 22 volumes is a manageable starting point that still feels substantial.

Who Should Collect My Monster Secret

This series is a great fit for:

• Romantic comedy fans who want supernatural flavor mixed into their rom-com. The romance is central and develops across the full 22 volumes, but it’s wrapped in monster and alien chaos and absurdist comedy.

• Readers who love big casts of characters. The supporting characters in My Monster Secret are arguably as entertaining as the leads. If you enjoy manga where every side character gets moments to shine, you’ll be very happy here.

• Manga newcomers. The 13+ rating, comedic tone, and straightforward reading order make this one of the easier completed series to pick up as a first manga. No complex reading guides, no mature content warnings, no “you need to read this other series first” prerequisites. You can find Volume 1 at major online retailers and bookstores — search for it by name and you’ll have options.

• Collectors who want closure. The completed status means you can read the entire story from first page to last without waiting for anything. Every volume exists. The ending is written. It’s a true finished manga experience.

The genres — comedy, supernatural, science fiction, romance — give you a sense of the flavor. (The sci-fi elements come primarily from the alien and time-traveler characters in the cast.) If any combination of those sounds appealing, Volume 1 is where you start. And if it clicks, you’ve got 21 more volumes of a story that only gets better as it goes.
