The series also released short vertical-format animated clips on YouTube, TikTok, and Instagram in April 2025, expanding its reach to new readers.

Synopsis

Koisuru One Piece follows a group of high school students who happen to share the same names as the iconic characters from One Piece. They form a fan club called the “Pirate Club,” reenacting or parodying famous scenes from the original manga while navigating their humorous high school lives.

The story blends typical school-life comedy with carefully crafted parodies inspired by the world of One Piece. It’s light-hearted, accessible, and particularly enjoyable for readers familiar with the original series.

Main Characters

To avoid spoilers and keep descriptions accurate, here are only the core characters:

  • Yamamoto Kaizoku-Ō (Luffy)
    A cheerful, energetic boy and the de facto leader of the “Pirate Club.”

  • Koyama Nami
    A smart, straightforward girl who shows affection toward Luffy. Her name echoes the original Nami.

  • Nakatsugawa Usofu (Usopp)
    A lively boy with an exaggerated imagination, clearly inspired by the original Usopp.

These characters form the heart of the manga’s school-life setting.

Story Progression

The series mainly consists of short, self-contained comedy episodes. Yet, character relationships gradually build over time, giving the manga a light but enjoyable sense of continuity.

After its hiatus, the series returned with Chapter 143 in 2025, featuring an over-the-top plot in which Sanji transfers to a girls' school. The return included brief recap elements to help new readers jump in, as well as a campaign where Chapters 1–50 were made free to read—an approachable move for newcomers.

What Makes This Manga Unique

1. Deep Love and Respect for the Original “ONE PIECE”

Although it is a parody, the manga is filled with genuine admiration for Eiichiro Oda’s world. The references are not superficial jokes—they come from a deep understanding of the original story. Many subtle details and “inside jokes” are included that only long-time fans will immediately recognize.

2. High-Quality Comedy

The high school setting allows for playful reinterpretations of well-known characters. The humor sometimes borders on absurdity, but each character is written with personality and purpose. This prevents the comedy from feeling cheap or disrespectful.

3. Positive Feedback Loop With the Original Series

Fans who know One Piece well will enjoy this manga even more. Conversely, Koisuru One Piece often inspires readers to revisit the original manga to catch details or re-experience key scenes. This mutual reinforcement is one of the series’ greatest strengths.

4. The Reliability of an Official Work

Because this is an officially approved spin-off by Shueisha, the humor stays within a respectful boundary while still being bold. The editorial team’s willingness to greenlight such a parody is noteworthy in itself.

5. Multimedia Expansion

With vertical short animations released in 2025, the series is not just a manga but part of a broader media presence, making it easier for new readers—especially international audiences—to discover.

My Impressions

Reading Koisuru One Piece was both surprising and genuinely delightful. At first, I wondered whether such a parody—using the names of One Piece characters not as pirates but as high school students—could truly work. But once I started reading, my doubts quickly disappeared. What stood out most was not the parody itself but the clear respect and affection toward the original series.

The jokes are not simply thrown in for easy laughs. They are based on a deep understanding of One Piece: its relationships, its themes, and its countless memorable scenes. Many jokes can only be fully appreciated by readers who know the original extremely well. Because of that, every chapter reminded me of how rich and layered One Piece truly is.

And strangely enough, this manga made me want to reread the original. The references, subtle callbacks, and clever reinterpretations create a powerful positive feedback loop—this spin-off becomes more enjoyable the more you know One Piece, and One Piece itself becomes even more enjoyable after reading this parody. Few official comedy works achieve this kind of synergy.

I also appreciate the courage and creativity of the editorial team. It takes confidence to allow a parody that pushes the boundaries of character interpretation, yet the result is respectful, joyful, and surprisingly thoughtful.

Personally, I hope Koisuru One Piece continues alongside the main story until the very end. While it’s a comedy and might not appeal to everyone, readers who truly love One Piece should at least give it a try—you may find yourself enjoying both series even more.

Conclusion

Koisuru One Piece is:

  • A high-quality school-life comedy with clever parody elements

  • Enriched by deep knowledge of the original One Piece

  • An official and respectful spin-off

  • A work that enhances readers’ appreciation of the original manga

  • Recommended especially for dedicated One Piece fans

Far more than a simple parody, this manga reads like a heartfelt love letter to One Piece. Whether you’re already a fan or just beginning your journey, Koisuru One Piece offers a fun, affectionate, and surprisingly insightful experience.

Pyū to Fuku! Jaguar  Review (Rating: 4.5 / 5) Overview Pyū to Fuku! Jaguar is a gag manga written and illustrated by Kyosuke Usuta. It was serialized in Weekly Shōnen Jump from 1999 to 2010. The work belongs to the genre often described as “nonsense gag comedy,” but even within that category, it stands out for its highly distinctive tone and structure. English Wikipedia: https://en.wikipedia.org/wiki/Py%C5%AB_to_Fuku!_Jaguar Synopsis The premise of Pyū to Fuku! Jaguar is deliberately simple. The story revolves around Jaguar Junichi, a mysterious man who lives in a run-down building and spends his days blowing a recorder. His encounter with Kiyohiko Sakaru, a young man who dreams of becoming a musician, leads to a series of strange and often absurd daily episodes. Rather than following a long, goal-oriented narrative, the manga is structured around short, self-contained chapters. Each episode focuses on conversations, misunderstandings, and unexpected reactions. The absence of ...

Azumanga Daioh  Review (Rating: 4/5)  Overview Azumanga Daioh is a Japanese manga series by Kiyohiko Azuma, set in a high school and focused on everyday life comedy. It was serialized starting in 1999 and later collected into four volumes (with newer editions also available). Despite its relatively short length, the series is widely regarded as one of the works that decisively shaped what is now known as the “slice-of-life” manga genre. Rather than centering on dramatic events or an overarching plot, the manga portrays ordinary school days in a calm, understated way. From this simplicity, it creates both humor and a lingering emotional aftertaste. While this style has since become familiar, it was still fresh at the time of publication, and Azumanga Daioh stands as one of its key starting points.
