The popular "sex and romance" manga series Sefure by Ryuta Amazume is set to conclude its publication in Shonengahosha’s Young King magazine. The announcement was made in the 15th issue of the magazine, released on Wednesday, confirming that the final chapter will appear in the upcoming issue on July 27th. This marks the end of a significant chapter for Amazume’s work, which debuted in March 2019.
A Look Back at the Sefure Journey
Sefure, which translates to "sex friend," delves into the complexities of a relationship that begins with a focus on physical intimacy but gradually evolves to explore deeper emotional connections between its two protagonists. The manga’s premise, centered on the nuanced development of feelings within a non-traditional romantic context, has resonated with a segment of the readership, contributing to its multi-volume run.
The series’ debut in March 2019 in Young King magazine was met with anticipation, given Amazume’s established presence in the manga industry. The publisher, Shonengahosha, has been diligently releasing compiled volumes, with the 11th volume of Sefure becoming available on May 2nd of this year, indicating a steady pace of production leading up to the series’ conclusion. This consistent release schedule underscores the publisher’s commitment to the title and its readers.
Ryuta Amazume’s Prolific Career and Recent Activity
The conclusion of Sefure signifies another completed project for Ryuta Amazume, an artist known for exploring mature themes and intricate character relationships in his work. Amazume has maintained a prolific output in recent years, with several series drawing to a close or launching.
Most recently, on April 23rd, Amazume concluded his manga Omae no Kao wo Tashikametai, also known as Let Me See That Look on Your Face. This series, which began serialization on Kodansha’s YanMaga Web website on September 11th, 2023, saw its second and final compiled volume released on June 19th. The swift conclusion of this project highlights Amazume’s ability to craft contained narratives.
Prior to Omae no Kao wo Tashikametai, Amazume’s manga Jofū came to an end in March 2025. This series, which had its origins as a one-shot published in Hakusensha’s Young Animal magazine in March 2021, later transitioned to full serialization in December 2021. The publication of its seventh and final compiled volume on May 29th marked the completion of Jofū.
A Deeper Dive into Amazume’s Notable Works
Amazume’s most enduring and widely recognized work is the Nana & Kaoru series, which has a significant history within the manga landscape. The original Nana & Kaoru manga began its publication journey in Hakusensha’s Young Animal Arashi in 2008, later migrating to the main Young Animal magazine in 2009. The series officially concluded in August 2016, leaving a lasting impact on its readers.
The popularity of Nana & Kaoru was further amplified by its adaptation into an original video anime (OVA) project and two live-action films. This multi-platform success demonstrates the broad appeal of the characters and narrative that Amazume created. Furthermore, Amazume penned the spinoff manga series Nana to Kaoru: Black Label, which concluded in 2014, expanding the universe of Nana and Kaoru.
Another notable spinoff, Nana to Kaoru: Kōkōsei no SM Gokko (High Schoolers’ S&M Play), launched in November 2018 as part of the inaugural issue of Hakusensha’s Harem magazine. This series, set during the protagonists’ third year of high school, wrapped up in October 2021 with its fifth and final volume released in December 2021.
The licensing and distribution of Nana & Kaoru have also contributed to its accessibility. FAKKU has licensed the manga for English release, and Denpa began distributing it in a 3-in-1 omnibus edition starting in October 2022, making the extensive series available to a wider international audience.
Industry Context and Reader Engagement
The conclusion of Sefure arrives at a time when the manga industry continues to adapt to evolving reader preferences and digital distribution models. Young King magazine, a publication known for its seinen demographic focus, has been a consistent platform for mature-themed manga. The consistent publication of Sefure suggests it has found a dedicated readership within this demographic.
The "sex and romance" genre, while not as mainstream as shonen or shojo, occupies a significant niche within the manga market. Series that successfully navigate this space often do so by balancing explicit content with compelling character development and narrative depth, a balance that Sefure has strived to achieve. The transition from a purely physical relationship to one with emotional stakes is a common narrative arc in such stories, and its execution in Sefure has evidently been sufficient to sustain it for over five years.
Analyzing the Implications of Series Endings
The conclusion of a manga series, while marking an end for readers, often signifies new beginnings for creators. For Ryuta Amazume, the completion of Sefure allows him to dedicate his full creative energy to new projects. Given his recent track record of concluding multiple series, it is highly probable that he is already engaged in or planning his next creative endeavor.
The consistent output and diverse range of themes explored by Amazume indicate a seasoned professional who understands the demands of the manga industry. The ability to launch, develop, and conclude multiple series across different publishers speaks to his adaptability and his capacity to connect with various editorial teams and target audiences.
From a market perspective, the conclusion of a series can impact sales of its collected volumes and related merchandise. However, for a mature-themed series like Sefure, the primary engagement is often driven by the ongoing narrative in the magazine. The final collected volume is anticipated to see a surge in sales as fans acquire the complete set.
Looking Ahead
As Sefure embarks on its final chapters, fans will undoubtedly be anticipating the resolution of the protagonists’ journey. The legacy of Ryuta Amazume in the manga world is firmly established through his diverse body of work, particularly the long-running Nana & Kaoru franchise and his recent explorations of complex relationships in titles like Sefure. The manga community will be keenly watching for what Amazume has in store next, confident in his ability to deliver engaging and thought-provoking narratives. The final issue of Young King featuring Sefure on July 27th will be a significant date for both the author and his dedicated readership.
