Aharen-san Is Indecipherable Manga Volumes: Full Guide

How Many Volumes of Aharen-san is Indecipherable Are There?

Here’s the quick answer: Aharen-san is Indecipherable (阿波連さんははかれない), created by Asato Mizu (水あさと), ran for 167 chapters and is collected in 17 volumes in Japanese. The series is complete. It was originally published chapter by chapter — a process called serialization — in Shonen Jump+, a digital manga magazine run by Shueisha, one of Japan’s largest publishers. That serialization ran from January 2017 to April 2023, and every chapter has been collected into standalone paperback editions (called tankobon in Japanese).

The English edition tells the same story but packages it differently. Instead of 17 individual volumes, the English release uses an omnibus format — meaning each English book bundles two Japanese volumes into a single, thicker paperback (a “2-in-1”). As of the latest release information, the English omnibus editions cover the equivalent of the first 4 Japanese volumes, meaning two omnibus books are available so far. The first omnibus launched in early 2026, so both volumes are recent and widely available.

Since each omnibus covers two Japanese volumes, the full English run will need roughly 9 omnibus books to cover all 17 Japanese volumes (the last one would contain only volume 17, or the publisher may adjust the final grouping). The English release is still in progress, but because the Japanese series is already finished, there are no surprises ahead. You know exactly how many books will exist and that the story has a definitive ending waiting for you.

The Easiest Way to Collect Aharen-san in English

The 2-in-1 omnibus format is genuinely one of the friendlier ways to collect a manga series. Instead of tracking down 17 individual books, you’re looking at roughly 9 total — that’s fewer books on your shelf, fewer purchases to make, and a tidier-looking collection when it’s all said and done.

Physical Omnibus Editions

Each English omnibus bundles two Japanese volumes into one book. For a series like Aharen-san, which is a lighthearted comedy rather than an action series with big two-page illustrations meant to be viewed across an open book, the omnibus format works well. You’re not losing much in the transition to a thicker spine, and the reading experience stays comfortable.

Digital Options

If you prefer reading on a tablet or phone, digital editions are worth watching for as the English omnibus line continues. Digital manga is typically available through platforms like Kindle, Kobo, and other major e-book storefronts, often releasing alongside or shortly after the physical editions. Going digital eliminates shelf space concerns entirely — especially handy if you’re collecting multiple series at once.

Importing the Japanese Edition

For readers who can’t wait for the English omnibus schedule to catch up, all 17 Japanese volumes are already available. Importing — ordering the original Japanese-language editions from retailers that ship internationally — is an option if you read Japanese or simply want the original editions for your collection. Just keep in mind that availability can vary volume by volume, and shipping costs from Japan add up.

Keeping Costs Down

The omnibus format naturally helps with cost. Fewer physical books means fewer individual purchases compared to a series released as single volumes. When all 9 or so omnibus editions are out, your complete English set will take up about half the shelf space of the Japanese release — and your wallet will feel the difference too.

English Omnibus Volumes at a Glance

Here’s what’s available and what’s coming in the English omnibus line.

Omnibus Covering Japanese Volumes 1–2

This is where it all begins. Raido sits next to Aharen in class and quickly realizes she’s… a lot. She speaks so quietly that he can barely hear her. She stands uncomfortably close. She gives him enormous, extravagant gifts for no reason. Raido’s attempts to decode her behavior are consistently, spectacularly wrong, and that misunderstanding engine is what drives the comedy.

These opening chapters establish the core dynamic: Aharen is genuinely sweet but socially calibrated on a completely different frequency, and Raido is earnest but overthinks everything to an absurd degree. It’s a simple formula, but the execution is what makes it work. The jokes land because both characters are so committed to their respective wavelengths.

Omnibus Covering Japanese Volumes 3–4

The supporting cast starts to fill in here. New classmates and friends enter the picture, giving Aharen and Raido more people to bounce off of — and more situations for their bizarre dynamic to play out. The comedy expands beyond the classroom into school events, outings, and everyday scenarios that let the humor breathe in new directions.

This stretch is also where you start to see hints that there might be something more than friendship developing between the two leads. It’s subtle (and frequently buried under layers of comedy), but it adds a layer that keeps you turning pages beyond just waiting for the next gag.

The latest English omnibus edition covers content through Japanese volume 4 and is a great way to get caught up on the series so far.

Remaining Omnibus Editions (Japanese Volumes 5–17)

The English publisher still has a lot of ground to cover. Japanese volumes 5 through 17 means at least 6–7 more omnibus editions are on the way. Specific release dates for upcoming volumes haven’t all been confirmed yet, so checking the publisher’s website or announcements page periodically is the best way to stay current on the schedule.

The good news: because the Japanese manga is completely finished, the English publisher is working from a fixed pool of material. There’s no risk of the source material going on hiatus or changing direction. Every remaining omnibus is just a matter of translation, production, and scheduling.

Availability Notes for Collectors

One of the nicest things about getting into Aharen-san right now is that you’re arriving early in the English release cycle. The omnibus line launched in early 2026, which means every English volume currently available is a recent release. You won’t run into the frustrating situation that plagues fans of older series — volumes going out of print and becoming hard to find at reasonable prices.

English Editions

Since the English omnibus editions are brand new, they’re widely stocked at major retailers. Supply is fresh, printings are current, and availability shouldn’t be an issue for the foreseeable future. This is the sweet spot for starting a collection: early enough that nothing is scarce, but late enough that you can confirm the series is worth your time (the whole Japanese run is already done, and fans liked how it ended).

Japanese Editions

The 17 Japanese volumes were published between 2017 and 2023. Availability through import retailers — shops that specialize in shipping Japanese books internationally — can be hit-or-miss depending on the volume. Earlier printings of the first few volumes may be harder to track down than later ones. If you’re specifically collecting the Japanese edition, checking multiple import shops for stock is a good habit.

Looking Ahead

As the English publisher continues releasing omnibus editions, watch for announcements about upcoming volumes. The release schedule will determine how quickly you can complete your English collection. With roughly 6–7 more omnibus books to go, you’re looking at a multi-year publishing timeline — but each new release gets you closer to that complete set.

A Finished Comedy You Can Read at Your Own Pace

This is the part that makes Aharen-san especially appealing for readers who’ve been burned by ongoing series. The manga ran from January 2017 to April 2023, spanning 167 chapters across 17 volumes, and it has a definitive ending. The story wraps up. You get closure.

No hiatuses. No indefinite waits between chapters. No anxiety about whether the creator will finish the story. It’s done, and it’s done on its own terms.

More Story Than the Anime

The anime ran for two seasons — Season 1 (12 episodes, April–June 2022) and Season 2 (12 episodes, April–June 2025) — covering a substantial portion of the manga’s storyline. Still, with 17 volumes and 167 chapters of source material, the manga goes further than 24 episodes of anime can cover. If you watched both seasons and wanted more Aharen and Raido — more gags, more character development, more of that warm comedic energy — the manga delivers. There are storylines and character moments that the anime didn’t get to, and reading the full manga gives you the complete picture of where these characters end up. (For the most seamless experience, starting from volume 1 is recommended even if you’ve seen the anime, since the manga includes details and scenes the adaptation skipped or condensed.)

Read at Whatever Speed Works for You

Because the series is finished, there’s zero pressure to keep up with a release schedule (aside from the English omnibus publication dates). You can binge the available volumes in a weekend, or you can pick one up every few months as a lighter read between more intense series. The comedy is structured so that each chapter works as its own little self-contained sketch — you can put it down and come back without losing track of what’s happening. That standalone-chapter quality holds up even as the larger relationship between Aharen and Raido develops over time.

Is Aharen-san is Indecipherable Worth Collecting?

Let’s break it down by what kind of reader you are.

If you love slice-of-life comedy (the genre focused on everyday life rather than big action or drama): This is right in the wheelhouse. The humor comes from character dynamics and misunderstandings rather than slapstick or references, which gives it a timeless quality. The jokes hold up on rereads because the character work is strong.

If you watched the anime and wanted more: The manga is the complete version of the story. Even with two full seasons of anime (24 episodes total), the 17-volume manga goes further and deeper. You’ll get to see how Aharen and Raido’s relationship develops all the way to its conclusion, with storylines and moments the adaptation couldn’t fit in.

If you’re just getting started with manga: Aharen-san is a genuinely approachable series. The chapters are light, the tone is warm, and there’s no dense continuity to keep track of. It’s the kind of manga you can hand to anyone and feel confident they’ll have a good time.

If shelf space matters to you: The 2-in-1 omnibus format keeps the physical collection compact. Roughly 9 books for the complete series is very manageable, even if your shelf is already crowded.

If you hate incomplete collections: A completed Japanese series being released in a predictable omnibus format means you can plan your collection with confidence. You know the story is done, you know approximately how many books it’ll take, and you know no surprise spin-offs or sequel series are going to force you to keep buying beyond the main story.

Aharen-san is Indecipherable isn’t trying to be an epic. It’s a cozy, funny, endearing comedy about two people who are completely on different wavelengths but somehow make it work. And for a collecting experience, it’s about as clean and straightforward as it gets: a finished story, a compact format, and fresh availability. If that sounds like your kind of read, grab the first omnibus and see for yourself.
