One Week Friends Manga Reading Order (All 7 Volumes)

One Week Friends Manga Reading Order at a Glance

This is a completed, linear series. No branching paths, no alternate timelines. You read Volume 1 through Volume 7, in order, and you get the entire story. (A sequel manga by a different creator exists — more on that below — but Hazuki’s original series stands completely on its own.)

For readers new to manga: a “volume” is a single book that collects several “chapters” — individual installments that were originally published one at a time. Think of chapters as episodes and volumes as seasons, bundled into one book each.

Volume	Story Focus
Vol. 1	The premise: Fujimiya’s weekly memory loss, Hase’s determination to befriend her
Vol. 2	Deepening friendship, supporting cast introduced
Vol. 3	The friend circle expands, emotional complications arise
Vol. 4	Romance tension grows beyond simple friendship
Vol. 5	The story begins uncovering the root of Fujimiya’s condition
Vol. 6	Major emotional turning points and revelations
Vol. 7	Full resolution — the series concludes here

Bottom line: grab Volume 1, read straight through to Volume 7, and you’re done. The series was originally published chapter by chapter in Monthly Gangan JOKER, a Japanese manga magazine published by Square Enix (known for Final Fantasy and other games, Square Enix also publishes manga magazines in Japan). Its volumes were released from June 2012 to April 2015, and the English edition from Yen Press — one of the major companies that licenses and translates manga for English-speaking readers — matches the Japanese release at 7 volumes. There’s nothing extra you need to track down.

Volume-by-Volume Breakdown

Even though the reading order is straightforward, the emotional journey of One Week Friends is carefully constructed. Each volume builds on the last in ways that make skipping or reading out of order a bad idea. Here’s what to expect as you go through.

Volumes 1–2: The Premise and First Steps

Volume 1 is where everything begins. Yuuki Hase notices that his classmate, Kaori Fujimiya, is always alone. She’s not unfriendly — she’s protecting people from the pain of being forgotten. Every Monday, her memories of the friends she made that week vanish completely. Hase decides he’ll befriend her anyway, reintroducing himself week after week.

It’s a premise that could easily become repetitive, but Hazuki handles it with remarkable restraint. The first volume is less about the mystery of why this happens and more about the simple, stubborn kindness of showing up for someone even when they won’t remember you did.

Volume 2 broadens the world. Hase and Fujimiya’s friendship starts developing a rhythm — diaries, notes, small rituals to bridge the gap each Monday creates. The supporting cast enters here too, and the dynamic shifts from a two-person story to something richer. You start to see that Fujimiya’s condition doesn’t just affect her — it shapes everyone around her in different ways.

These two volumes together establish the emotional rules of the series. Everything that follows depends on what’s built here, which is why even anime viewers benefit from reading them.

Volumes 3–4: Expanding the Circle

Volume 3 introduces new characters who complicate the emotional landscape in ways that feel natural rather than forced. One Week Friends is not a story that relies on love triangles for drama, but it does understand that when more people enter someone’s life, the stakes get higher. Fujimiya’s condition becomes harder to navigate as more people care about her — and as she begins caring about more people.

Volume 4 is where the romance tension between Hase and Fujimiya shifts from something unspoken to something the characters (and readers) can’t ignore anymore. This isn’t a series that rushes into dramatic confessions. The progression is slow, deliberate, and earned. The question stops being “will they become friends?” and starts becoming “what happens when friendship isn’t enough to describe what they feel?”

These middle volumes are the heart of the series. The pacing is gentle — this is a character-driven school romance, not an action manga — and if you’re the kind of reader who likes watching relationships develop through small, honest moments, this is where One Week Friends really shines.

Volumes 5–7: Resolution and Conclusion

Volume 5 marks a shift in tone. The story begins moving toward understanding why Fujimiya’s memory works the way it does. Without spoiling specifics, the series doesn’t treat her condition as a simple plot device — it has roots in her past, and uncovering those roots changes the dynamic between the characters significantly.

Volume 6 delivers major emotional turning points. Revelations here reframe earlier events in the series, and the relationships between characters are tested in meaningful ways. This is the volume where readers who’ve been patiently following along get rewarded for their investment.

Volume 7 wraps everything up. The central romance reaches its conclusion, and the story’s emotional threads tie together satisfyingly. One of the strengths of One Week Friends is that it knows when to end — 7 volumes is exactly the right length for this story. It doesn’t drag on past its natural conclusion, and the ending feels complete rather than rushed.

The entire series — all 38 chapters across 7 volumes — tells one cohesive story from beginning to end. When you finish Volume 7, Hazuki’s story reaches its conclusion.

A sequel manga titled Sono Ato no Isshūkan Friends, drawn by a different artist (Jura) and serialized in Square Enix’s Gangan Joker, was announced in 2021. It is a separate continuation rather than part of Hazuki’s original run — the 7-volume series is self-contained and complete on its own.

Where the Anime Fits In

A TV anime adaptation of One Week Friends exists — meaning the story was turned into an animated television series based on the manga. If you’ve seen it, you might be wondering whether you can skip ahead in the manga.

Here’s what to know: the anime covers roughly the first half of the manga’s story, approximately through the events of Volume 4. It does not cover the complete series. The manga continues well past where the anime ends and delivers the full conclusion to Hase and Fujimiya’s story. If you only watched the anime, you haven’t seen how the story actually wraps up.

Two options for anime viewers:

• Start from Volume 1 anyway. This is the recommended approach. The manga has its own pacing and includes details, characters’ inner thoughts, and small character moments that the anime either condenses or skips. Reading from the beginning is a different experience even for scenes you’ve already seen animated.

• Pick up from Volume 5. If you’re short on time and just want to see how the story ends, you can start at Volume 5 and continue through Volume 7. Just be aware that you may miss some context and character development that the manga handles differently from the anime, particularly in Volumes 3 and 4.

Either way, the manga is the complete version of this story. The anime is a lovely adaptation of part of it, but One Week Friends was always meant to be read through to Volume 7.

Where to Buy One Week Friends in English

All 7 volumes are published in English by Yen Press and available through major retailers in both print and digital formats. Since the series is complete, you can buy and read the whole thing at your own pace without waiting for new releases.

There’s no omnibus edition (a combined book that bundles multiple volumes into one) or special box set — individual volumes are the way to go. Volume 7 is the final volume and wraps up the entire story.

A few practical notes:

• Start with Volume 1. There are no prequels or prerequisites. Volume 1, Chapter 1, Page 1 — that’s your starting point. The buy link above is for Volume 7, the series finale — but all seven volumes are available from the same retailer and easy to find from there.
• Digital is widely available. If shelf space is tight or you want to start reading immediately, the digital editions contain the same content as the print versions. Manga reads well on tablets; on smaller phone screens, you may want to zoom in on some panels to catch details in the artwork.
• Check multiple retailers for availability. Since the series has been complete for a while, some individual print volumes may go in and out of stock at different shops. If a particular volume is temporarily unavailable at one retailer, it’s often in stock at another.

The full series at list price is a modest investment for a complete, satisfying romance manga. Seven volumes is easy to collect and doesn’t require the shelf commitment of longer-running series.

Common Mistakes New Readers Make

One Week Friends is a simple series to get into, but there are a few things that trip people up — especially if they’re coming from the anime or are newer to manga in general.

Assuming the anime covers the whole story. This is the biggest one. The anime is wonderful, but it adapts only roughly the first half of the manga. If you stopped at the anime’s ending and thought “that’s how it ends” — it’s not. The manga goes further, digs deeper into Fujimiya’s past, and gives the romance a proper resolution. You’re missing the back half of the story.

Skipping early volumes after watching the anime. Even though you’ve seen the events animated, the manga’s pacing and Hazuki’s artwork tell the story differently. Characters’ inner thoughts, quiet panels, and small character beats don’t always survive the adaptation process. Readers who skip to where the anime ends often feel like they’re missing context — because they are.

Expecting fast-paced drama or action. One Week Friends is a quiet, character-driven school romance. The tension comes from emotion, not plot twists or cliffhangers. If you go in expecting high drama every chapter, you’ll be disappointed. But if you’re in the mood for something gentle and sincere — a story about patience, kindness, and showing up for someone even when it’s hard — this series is genuinely special. Set your expectations for warmth, not adrenaline.

Overthinking the reading order. Because manga reading orders can be genuinely complicated for some series — where multiple spin-offs, prequels, and alternate timelines make the path confusing — new readers sometimes arrive here expecting that same complexity. One Week Friends has none of that. Seven volumes, straight through. That’s it. Don’t overcomplicate it.

FAQ

How many volumes of One Week Friends are there?

Seven volumes total, containing 38 chapters. The series is fully complete — no ongoing releases or future volumes to wait for.

Do I need to read anything before starting?

No. One Week Friends has no prequels, no companion series, and no required background reading. Volume 1 is your starting point and it gives you everything you need.

Is One Week Friends finished?

Yes — Matcha Hazuki’s original manga was serialized in Monthly Gangan JOKER, with volumes released from June 2012 to April 2015, and is fully concluded at 7 volumes. The English edition from Yen Press is also complete. A sequel manga titled Sono Ato no Isshūkan Friends, drawn by a different artist (Jura), began serialization in 2021, but the original series tells a complete, self-contained story.

Should I read the manga or watch the anime first?

Either works. The anime is a faithful and charming adaptation of the early portion of the story and serves as a fine introduction. However, the manga continues past where the anime ends and delivers the full conclusion. If you only have time for one, the manga gives you the whole story.

Who is the author?

One Week Friends was created by Matcha Hazuki (葉月抹茶). It was originally published chapter by chapter in Square Enix’s Monthly Gangan JOKER magazine — a Japanese manga magazine where new chapters appear on a monthly schedule before being collected into the volumes you buy in stores.

Is this a romance manga?

Yes, though it starts as a story about friendship and gradually develops into a romance. The relationship between Hase and Fujimiya grows naturally over the course of all seven volumes. If you enjoy school romances that take their time and build genuine emotional depth, this series is a great fit.
