One Week Friends Manga Volumes: All 7 Books Explained

One Week Friends: The Complete Manga at a Glance

One Week Friends (一週間フレンズ。) is a completed manga by Hazuki Matcha (葉月抹茶) that tells one of the most quietly heartbreaking stories in school romance manga — and wraps it all up in just 7 volumes. If you’re searching for details on every One Week Friends manga volume, you’re in the right place: the series is finished, fully available in English, and short enough to collect without a major commitment.

The premise is deceptively simple: a high school boy named Yuki Hase wants to become friends with Kaori Fujimiya, a girl who sits alone and keeps everyone at a distance. The reason? Every Monday, her memories of her friends reset. She forgets the people she’s grown close to, and the cycle starts over.

Yuki decides to befriend her anyway. Every single week.

The series ran in Monthly Gangan JOKER (a Japanese manga magazine published by Square Enix) and spans 38 chapters across those 7 volumes. In manga, chapters are individual installments — usually around 20 to 40 pages each — that get collected into the bound volumes you buy. In English, all 7 volumes are available from Yen Press (a US publisher that translates Japanese manga into English), carrying a Teen rating that makes the series accessible to a wide range of readers.

If you’re looking for a manga that’s short enough to finish over a weekend but emotionally resonant enough to stick with you, One Week Friends is a fantastic pick. It’s a complete story with a real ending — no waiting for future volumes, no cancellation cliffhangers.

What Each One Week Friends Manga Volume Covers

With 38 chapters spread across 7 volumes — roughly 5 to 6 chapters per volume — One Week Friends moves at a consistent, brisk pace. Each book builds naturally on the last, and the story never feels padded or stretched thin. Here’s a general sense of how the narrative unfolds.

Volumes 1–2: The Foundation

The opening volumes establish the central premise and make you feel its weight. Yuki begins his weekly routine of approaching Kaori, introducing himself, and slowly earning her trust — only for her to forget him come Monday. These early chapters are where the series draws you in. You watch Kaori’s guarded exterior soften over the course of each week, and you feel the sting when it resets.

Key supporting characters also enter the picture here, providing both comic relief and emotional grounding. By the end of Volume 2, the core friend group is taking shape, and the story has laid the emotional groundwork for everything that follows.

Volumes 3–4: Deepening Bonds

The middle stretch is where One Week Friends grows beyond its initial premise. The friend group expands, relationships become more complex, and the manga starts asking harder questions about why Kaori’s memory works the way it does. The cause of the memory resets comes into sharper focus, and the story gains a layer of mystery alongside its emotional core.

These volumes also do a wonderful job with the supporting cast. Friendships between secondary characters develop in ways that feel earned rather than obligatory, giving the story more texture.

Volumes 5–6: Past and Present Collide

New characters arrive and challenge the group dynamic. Past connections between characters begin to surface, adding tension and raising the emotional stakes. The story accelerates noticeably here — threads that were planted in earlier volumes start paying off, and you can feel the narrative building toward its conclusion.

Without spoiling specifics, these volumes shift the tone in ways that make the final stretch feel genuinely urgent.

Volume 7: The Conclusion

The final volume brings One Week Friends to its full emotional resolution. Everything the series has been building — the friendships, the mystery, the feelings between the characters — reaches a satisfying endpoint. A bonus chapter (an extra story published after the main series officially ended) is also included, giving readers a little more time with these characters after the main story wraps. You get this bonus chapter as part of the standard Volume 7 release, so there’s nothing extra you need to track down.

Having that complete ending is one of the best things about picking up this series. You’re not left hanging. The story knows where it’s going and gets there.

Reading One Week Friends in One Go

At 7 volumes, One Week Friends is practically built for marathon reading. The emotional throughline is continuous — each volume ends on a moment that makes you want to grab the next one immediately — and the overall length is manageable enough that most readers will finish the whole series in a few dedicated reading sessions.

Suggested Break Points

If you want to pace yourself a bit rather than powering through all 7 volumes at once, here are natural stopping points:

• After Volume 2 — The foundation is set. You understand the premise, you care about the characters, and you have a clear sense of whether the series is for you. This is a good spot to take a breather before the story deepens.
• After Volume 4 — The midpoint marks a tonal shift. The mystery elements become more prominent, and the emotional dynamics change. Pausing here lets you sit with that shift before heading into the final stretch.
• Volumes 5–7 as a single block — Once you hit Volume 5, the pacing picks up and the story accelerates toward its conclusion. Reading these three together gives you the full emotional arc of the ending without interruption.

That said, plenty of readers just blow through the entire series in one sitting — and at this length, that’s completely reasonable. There’s something special about experiencing the whole story of Yuki and Kaori’s friendship in a single unbroken read.

Manga vs. Anime — What the Adaptation Covers

A TV anime adaptation (a Japanese animated television series based on the manga) of One Week Friends aired beginning in April 2014, while the manga was still being published. The anime is a lovely production in its own right, with a soft visual style that suits the story’s tone.

However, the anime does not cover the full manga. Since the manga continued running after the anime aired, readers who have only seen the anime are missing significant story content — including the actual ending. If you watched the anime and want the complete story, picking up the manga from the beginning is the way to go. While the anime covers material from the earlier volumes, reading from Volume 1 gives you the full narrative as the manga tells it.

The manga is the definitive complete version of One Week Friends. It’s where the full 38-chapter story lives, from the first meeting to the final resolution.

For readers who finish the manga and want even more, a related sequel work titled その後の一週間フレンズ。 (roughly “One Week Friends: After That”) also exists, continuing the story beyond the original manga’s ending. As of this writing, this sequel has not been released in English.

Which Edition to Buy

One Week Friends manga volumes are available in a few different formats depending on your language and reading preference.

English Editions

Yen Press publishes the complete English-language release in both paperback and digital formats. All 7 volumes are available in each format and the English release is fully complete, so whether you prefer physical books on your shelf or reading on a tablet, you can get the entire series right now.

At only 7 volumes and standard manga pricing per book, collecting the full set is affordable relative to longer series and doesn’t take up much shelf space. There’s no omnibus edition (a collected book that combines multiple volumes into one), but with a series this short, individual volumes feel like the natural format anyway. You can line up all seven on your shelf and have the entire story right there.

Japanese Editions

In Japanese, the series was published as standard paperbacks under the Gangan Comics JOKER imprint. A limited first-edition deluxe version also exists for collectors, though availability of those special editions varies.

Digital vs. Physical

This really comes down to personal preference. Both the digital and physical English editions contain the complete story with identical content. Physical volumes are great for collecting and re-reading; digital is convenient if you’re short on shelf space or want to start reading immediately.

For a series as short as One Week Friends, buying the complete physical set is satisfying in a way that longer manga sometimes aren’t — you can hold the entire story in your hands without needing a dedicated bookshelf.
