Akuma no Riddle Manga Complete Reading Order
The reading order here is straightforward. Akuma no Riddle is a completed manga series, and you read it in standard publication order. There are no timeline jumps, prequels, or alternate continuities to sort through.
Here’s the full reading order:
- Volume 1 — Introduces Class Black, Tokaku, Haru, and the deadly premise. Tokaku makes the pivotal choice to protect Haru instead of assassinating her, setting up the central conflict.
- Volume 2 — The first assassination attempts hit in earnest. Each attacker gets their own backstory — their trauma, their reasons for joining Class Black — and Tokaku begins to prove just how far she’ll go to keep Haru alive.
- Volume 3 — Alliances crack as the remaining assassins grow more desperate. Tokaku’s own past as a member of an assassin clan starts surfacing, complicating her motivations and her bond with Haru.
- Volume 4 — The later-stage assassins are more dangerous and psychologically manipulative than those who came before. Haru’s own secrets — and why she was selected as the target — start coming into focus.
- Volume 5 — The final confrontations, the truth behind Class Black, and the manga’s conclusion. The ending diverges significantly from the anime, so manga readers get a distinct resolution.
That’s the complete main series. Each volume follows the next without any reordering needed.
If you encounter any bonus chapters or side material (more on that below), those are best read after finishing the main five volumes. Nothing supplementary is required to understand the core story.
The English edition was published under the title Riddle Story of Devil, so don’t be confused if you see that name on covers — it’s the same series.
Why Reading Order Matters for Akuma no Riddle
You might be wondering: with only five volumes, does reading order really matter? For this particular series, yes — more than you’d expect.
The Assassination-Classroom Structure
Akuma no Riddle is built around a repeating but escalating structure. Each story arc — meaning a self-contained section of the story spanning several chapters — focuses on a different assassin from Class Black making their move against Haru. Along with each attempt comes that assassin’s backstory: their motivations, traumas, and reasons for accepting the mission.
These arcs are carefully sequenced. Earlier assassins tend to be more straightforward in their methods and motivations, while later ones introduce increasingly complex psychological dynamics. Reading out of order would spoil the carefully built tension and undermine the reveals that make each new confrontation feel more dangerous than the last.
Cumulative Character Development
Tokaku and Haru’s relationship deepens volume by volume. Early on, Tokaku’s decision to protect Haru feels impulsive and unexplained. As the series progresses, layers are peeled back on both characters — Tokaku’s history as an assassin, Haru’s true nature and the secrets she carries. Skipping ahead means losing the slow-burn development that gives the later emotional beats their weight.
The Manga vs. Anime Ending
This is a big one. The anime adaptation aired in 2014 and covered the general premise, but its ending diverges significantly from the manga’s conclusion. Many fans consider the manga ending darker and more thematically consistent. If you’ve seen the anime and are coming to the manga expecting the same resolution, you’ll want to read in order to appreciate how the manga builds toward its own distinct conclusion.
Where to Start If You’re New to the Series
Start with Volume 1. There’s no trick to it — Akuma no Riddle is entirely self-contained, and Volume 1 sets up the whole premise. You’ll meet Tokaku, Haru, and the rest of Class Black within the first few chapters.
What to Expect Tonally
Akuma no Riddle is best described as a dark psychological thriller — a story driven more by tension, paranoia, and character psychology than by action alone — with yuri romance at its core. It’s not a straight horror manga, but if you enjoy horror and are looking for something in a neighboring space, this series delivers a constant atmosphere of danger and dread that scratches a similar itch.
There’s violence — these are assassins, after all — but the series leans more into mind games and emotional conflict than graphic gore. The horror element comes from the premise itself: being trapped in a classroom where almost everyone around you is trying to kill you or the person you care about. If you read horror manga for the suspense and unease rather than the shock value, Akuma no Riddle fits that niche well.
Content note: The series contains violence, themes of trauma and abuse in several characters’ backstories, and life-or-death situations throughout. It’s not extreme by horror manga standards, but readers sensitive to these topics should be aware going in.
Approachability
At five volumes, this is one of the most approachable dark manga series out there. You can realistically read the entire thing in a weekend. For readers who want to test the waters of darker manga without the commitment of a long-running series, Akuma no Riddle is a solid entry point.
The yuri elements are integral to the story rather than being added for titillation — Tokaku and Haru’s bond is the emotional engine driving the entire narrative. If you enjoy character-driven stories where relationships develop under extreme pressure, this series does that well.
Spin-Offs and Side Stories — Where They Fit
Akuma no Riddle’s supplementary material is limited compared to larger franchises, but there are a few things worth knowing about.
Bonus Chapters and Extra Content
Some volumes of the Japanese release included bonus chapters or short side stories that flesh out individual assassins from Class Black. These brief stories typically explore a character’s background before they entered Class Black, or show moments between the main story’s arcs.
When these appear in the collected volumes, they’re already placed in context — so if you’re reading the volumes in order, you’ll encounter them naturally without needing a separate guide.
Other Side Material
The series has some associated supplementary content beyond the main five volumes. Any such material is best saved for after you finish the main series. The five-volume storyline is completely self-contained, and nothing in the side material is necessary to understand or appreciate the core narrative. English-language availability of supplementary content is limited — the main series received a full English release, but not all bonus material made the jump. If you’re reading in English, the five main volumes give you the complete story.
Where to Buy Akuma no Riddle in English
The English edition of the manga was released under the title Riddle Story of Devil. Here’s what you need to know about finding it.
Publisher and Format
The English-language edition was published by Seven Seas Entertainment, a publisher that specializes in manga and light novel translations for the English-speaking market. They released the series in physical single-volume format matching the Japanese release structure.
Physical Copies
Physical volumes may be available through major retailers, though availability can fluctuate since the series has been complete for some time. Some volumes may be harder to find new than others, so checking multiple retailers is worthwhile. Used copies from reputable sellers are another option for completing your collection.
Volume 1 is the natural starting point — and since the series runs only five volumes, the final volume, Vol. 5 (shown below), is also within easy reach for readers looking to complete the set:

Digital Options
Digital editions offer the most reliable way to access the complete series. Kindle and BookWalker (a digital storefront specifically designed for manga and light novels) typically carry the full run of completed manga series, making them a strong option if physical copies prove difficult to track down. Kobo may carry the series as well — worth checking if that’s your preferred platform.
Digital also has the advantage of instant access — no waiting for shipping or hunting for out-of-print volumes.
Frequently Asked Questions
How many volumes is Akuma no Riddle?
The main manga series is five volumes long. It’s a compact, complete story that doesn’t require a massive time or money investment to finish.
Is the manga finished?
Yes. Akuma no Riddle is a completed series. All chapters have been published and collected into volumes, so you can read from start to finish without worrying about waiting for new releases or dealing with an unfinished story.
Should I watch the anime or read the manga first?
Either works as an entry point, but many fans recommend the manga. The 2014 anime adaptation covers the same general setup — Class Black, Tokaku protecting Haru, each episode featuring a different assassin making their attempt — but it diverges from the manga in its final act. The manga’s ending is generally considered darker and more satisfying from a narrative standpoint.
If you’ve already watched the anime and enjoyed the premise, the manga is absolutely worth reading for the different conclusion alone. And if you haven’t experienced either version yet, starting with the manga gives you the story as originally intended.
Is Akuma no Riddle a horror manga?
Not in the traditional sense, but horror fans will find plenty to like here. The premise — a class full of assassins targeting one student — creates a constant atmosphere of danger and paranoia. The tension comes from not knowing who will strike next, what methods they’ll use, and whether Tokaku can keep Haru alive.
If you enjoy manga that keeps you on edge through suspense rather than shock, Akuma no Riddle fits that niche well. For readers coming from the horror manga world looking for something with a slightly different flavor — more thriller, more character drama, with a central romance that adds emotional stakes — this is a great series to have on your radar.
