If you’ve been searching for a complete rundown of the Parallel World Pharmacy manga volumes — how many exist, what’s available in English, and whether the series is worth picking up — you’re in the right place. This is an isekai series, meaning the story follows a character who is transported or reborn into another world. What sets it apart from most isekai manga is its focus on medicine and science rather than combat. The series is still going strong, so let’s break it all down.
Parallel World Pharmacy Manga — How Many Volumes Are There?
Here’s the quick answer: Parallel World Pharmacy (異世界薬局) currently has 12 volumes published in Japanese and 7 volumes available in English. The series is ongoing, so more volumes are on the way in both languages.
The manga is based on the light novel by Takayama Rizu — a light novel being a style of short Japanese novel, typically published in serialized installments, that often serves as the source material for manga and anime adaptations. The manga version is illustrated by Takano Sei with character designs by keepout. It’s been serialized — meaning published chapter by chapter on an ongoing basis — on ComicWalker, KADOKAWA’s free digital manga platform, since November 2016. The English edition is published by One Peace Books.
For English readers, 7 volumes gives you a solid chunk of story to work through. The English release is still catching up to the Japanese edition, with new volumes coming out roughly every several months. That means there’s plenty more content on the way. If you’re the type who likes to binge a series, you’ve got enough to get properly hooked while still having future volumes to look forward to.

Story Arcs and What Each Volume Covers
Before getting into the breakdown — an “arc” just means a stretch of chapters that tell a self-contained storyline within the larger series — here’s the premise: a brilliant modern-day pharmacologist dies and is reincarnated as Farma de Médicis, a young nobleman in a medieval fantasy world where medicine is primitive at best and downright dangerous at worst. Farma retains his pharmaceutical knowledge from his previous life — and discovers he’s also been gifted with extraordinary divine-level powers in this new world. The series follows him as he tries to bring real medical science to a society that desperately needs it.
What makes this series stand out among isekai manga is the focus. Farma isn’t swinging a sword or collecting a cast of romantic interests — he’s diagnosing diseases, formulating medicines, and navigating the political and religious structures that control healthcare in his world. It’s genuinely educational at times, weaving real pharmacological concepts into its fantasy setting.
Early Volumes — Reincarnation and Establishing the Pharmacy
The opening stretch of the manga covers Farma’s reincarnation and the disorienting process of adjusting to his new life. He’s the son of a powerful court physician — essentially the personal doctor to the royal family, which places Farma squarely among the ruling class — and that position brings both noble privilege and heavy expectations.
These early volumes do a great job establishing the stakes. Medicine in this world is controlled by powerful trade organizations and religious institutions, and Farma’s ideas about evidence-based treatment — the practice of using tested, proven methods rather than tradition or superstition — are genuinely radical in context. He discovers his “divine arts,” a unique ability to create and destroy matter down to the molecular level, which gives him tools no other healer in this world has access to.
The emotional core of these volumes is Farma’s decision to open his own pharmacy, one that serves commoners as well as nobility. It’s a simple idea, but the manga sells it beautifully. His first encounters with diseases in this world — conditions that would be treatable with modern medicine but are death sentences here — give the series real emotional weight without ever tipping into melodrama.
If you’re wondering whether this series is for you, these early volumes are the perfect test. They balance world-building, character development, and medical problem-solving in a way that feels fresh and genuinely engaging.
Middle Volumes — Epidemics and Expanding Influence
As the series moves into its middle stretch, the scope expands considerably. Farma moves beyond treating individual patients and starts confronting large-scale medical crises — epidemics that threaten entire regions. The manga introduces specific diseases modeled on real historical plagues, and watching Farma work through diagnosis, containment, and treatment using modern medical logic is where the series is at its most gripping.
The world-building deepens significantly here. Political factions, religious authorities, and rival medical practitioners all react to Farma’s innovations in ways that feel believable. Not everyone is happy about a young nobleman upending centuries of medical tradition, and the resistance he faces — from those who profit from the old system and those who genuinely fear change — creates real tension that carries across multiple volumes.
The art also shines in these volumes. Takano Sei’s illustration work captures both the beauty of the fantasy setting and the gravity of the medical situations Farma faces. Disease and suffering are depicted with appropriate seriousness without being gratuitous.
Later Volumes (Japanese Only So Far)
Beyond the 7 Parallel World Pharmacy manga volumes currently available in English, the Japanese edition continues through volume 12 — and without getting into heavy spoiler territory, the series pushes Farma into confrontations with larger institutional forces and medical challenges that go beyond anything he’s faced before. The pharmacy itself grows in scope and influence, and new characters bring fresh complications to both the medical and political sides of the story.
If you’ve enjoyed the first 7 volumes in English, there’s a lot to look forward to as the English release continues to catch up.
For readers who can read Japanese, the full 12 volumes are available. For everyone else, the English release schedule from One Peace Books has been steady, so patience will be rewarded.
Where the Light Novel and Anime Fit Alongside the Manga Volumes
Parallel World Pharmacy didn’t start as a manga — it began as a light novel series, published by KADOKAWA under its MF Books imprint. The light novel ran for 10 volumes from January 2016 to January 2024, when the series reached its conclusion. The manga adaptation, now at 12 volumes and still ongoing, has actually surpassed the light novel — continuing the story beyond where the original novel ended.
There’s also a 12-episode anime adaptation that aired in 2022, covering roughly the earliest portion of the story. The anime is available on streaming platforms like Crunchyroll and is a solid introduction to the world and characters, but as is often the case with adaptations, it condenses the source material — meaning some scenes, details, and character moments from the manga are trimmed or cut to fit the shorter runtime. If you’ve watched the anime and are wondering whether the manga is worth reading — yes, absolutely. The manga offers significantly more detail, better pacing, and deeper exploration of the medical and political elements that make the series interesting. The manga picks up the full story from the beginning, so you’d start with volume 1 rather than trying to skip ahead.
So which format should you start with? Here’s a simple breakdown:
| Format | Best For |
|---|---|
| Manga | The most balanced experience — visual storytelling with good pacing and detail, and the version that has progressed furthest in the story |
| Anime | A quick taste of the premise and characters — great if you want to preview before committing (12 episodes) |
| Light Novel | The original prose version of the story — completed at 10 volumes, ideal if you prefer reading prose and want the author’s full narrative voice |
The manga stands completely on its own. You don’t need to watch the anime first, and you don’t need to read the light novel to understand or enjoy it. Each format tells the same core story through a different lens.
That said, if you enjoy the world and want to experience the story from its original prose perspective, the completed light novel offers a different reading experience — though the manga has now continued the narrative further than the novel reached.
Which Edition Should You Buy?
Let’s talk about actually getting your hands on the series.
The English edition of Parallel World Pharmacy, published by One Peace Books, is available in both physical and digital formats. The physical volumes are standard manga-sized paperbacks with solid print quality. If you prefer reading on a tablet or e-reader, the digital editions are available through platforms like Kindle, Kobo, and other major digital storefronts.
The main thing to keep in mind is the volume gap: there are 12 Japanese volumes but only 7 English volumes so far. The English release is ongoing and has been coming out at a steady pace, so you can expect more volumes to follow. But if you’re the type who hates waiting for the next volume — fair warning, you’ll be caught up sooner than you might think.
For new readers, the recommendation is straightforward: start with volume 1 and read in order. This isn’t a series where you can jump in at a random point. The story builds on itself — Farma’s relationships, his growing understanding of his powers, and the political landscape all develop progressively. Starting from the beginning gives you the full experience.
Volume 1 is your entry point and the best way to find out if this series clicks with you. It establishes the premise, introduces the key characters, and gives you a clear sense of the tone and pacing you can expect going forward.
Parallel World Pharmacy Volume 1
For Japanese readers or those studying the language, the manga chapters are available for free on ComicWalker, KADOKAWA’s official platform (primarily in Japanese). The collected print volumes are also available through Japanese retailers. With 12 volumes out, Japanese readers are significantly ahead of the English release.
Physical vs. Digital — Quick Comparison
| Factor | Physical | Digital |
|---|---|---|
| Art quality | Full print resolution on paper — nice to hold | High resolution on tablets and e-readers |
| Storage | Takes shelf space (7+ volumes and growing) | No physical storage needed |
| Availability | Major online and local retailers | Instant download from Kindle, Kobo, and other platforms |
| Collectibility | Great for shelf display | No physical collection to show off |
Both formats give you the same content, so it really comes down to personal preference. Some readers love having manga on their shelf; others prefer the convenience of a digital library. Neither choice is wrong.
Frequently Asked Questions
How many Parallel World Pharmacy manga volumes are there?
As of the latest verified data, there are 12 volumes in Japanese and 7 volumes in English. The series is ongoing, so both counts will continue to grow.
Is the Parallel World Pharmacy manga finished?
No — the manga is still ongoing. It’s been published on ComicWalker since November 2016 and new chapters continue to come out. There’s no announced end date.
Is the manga different from the light novel?
The manga is an adaptation of the light novel. It tells the same core story but in a visual format. The light novel contains more detail and more of the main character’s inner thoughts, while the manga brings the world and characters to life through Takano Sei’s artwork. They complement each other well, but you don’t need to read both — each works as a standalone experience.
Do I need to watch the anime before reading the manga?
Not at all. The manga stands entirely on its own and actually covers the story in greater detail than the 12-episode anime. If you’ve seen the anime, the manga will still offer plenty of new content and deeper exploration. If you haven’t seen it, you won’t be missing anything — the manga gives you everything you need.
When will the next English volume come out?
The English release from One Peace Books has been ongoing with a steady publication pace. For the most current release schedule, check One Peace Books’ website or major book retailers for pre-order listings. New volumes have been coming out regularly, so the English edition is steadily closing the gap with the Japanese release.
Is this a good manga for isekai beginners?
Absolutely. For anyone unfamiliar with the term, “isekai” is a genre of Japanese fiction where a character is transported to or reborn in another world — it’s one of the most popular categories in manga and anime. Parallel World Pharmacy is one of the more accessible isekai series because its premise is so grounded. Instead of complex game mechanics or power systems, the story revolves around medicine and science — concepts that are easy to follow even if you’re new to the genre. The characters are likable, the pacing is smooth, and the stakes feel real without being overwhelming. It’s a great starting point if you’re curious about isekai manga but aren’t sure where to begin.
