Tatsuya Suganuma’s manga series, “Nice Prison,” has officially ended its serialization in Weekly Shonen Jump with its 19th chapter, featured in Issue #41 of 2025. The comedy-crime manga, which began its run only a few months prior, joins a growing list of titles that have seen early conclusions in the popular magazine this year.
The Brief Run of “Nice Prison”
“Nice Prison” made its debut in Weekly Shonen Jump in Issue #21 of 2025, quickly establishing a unique premise within the shonen landscape. Despite its initial promise, the series was ultimately cut short, concluding with Chapter 19 in Issue #41. This short serialization period indicates a cancellation rather than a natural conclusion, a fate that has become increasingly common in the magazine.
Serialization Details
The manga’s journey in Weekly Shonen Jump spanned from Issue #21 to Issue #41 in 2025, totaling 19 chapters. This relatively short run placed “Nice Prison” among other series that did not manage to achieve a long serialization within the highly competitive magazine. Readers could follow the series on platforms like MANGA Plus and VIZ Media, which offered official English releases.
Premise and Characters
“Nice Prison” introduced readers to the quirky world of Nobana-shi Prison, a facility designed for the most unruly criminals. The story centered around Horo Mitsuboshi, a “super model prisoner” who was born and raised within the prison’s walls. His unusual mission was to bring “peace and niceness” back to the wild environment, often by confronting “super death row prisoners.” The narrative often involved new guard Tera Adachi, who follows in her father’s footsteps and encounters Horo’s unique methods for maintaining order. The manga was noted for its comedic and often absurd elements, featuring a diverse cast of unusual inmates, including a character who might be a cicada.
A Trend of Cancellations in Shonen Jump
The swift ending of “Nice Prison” highlights a significant trend observed in Weekly Shonen Jump throughout 2025. The magazine has seen a notable number of series conclude, with many being cancellations rather than authors bringing their stories to a planned finish.
2025’s Landscape for New Manga
“Nice Prison” is reportedly the tenth major series to end in Shonen Jump in 2025 alone. This wave of conclusions comes after the magazine saw major titles like My Hero Academia and Jujutsu Kaisen wrap up towards the end of 2024, creating space for new entries. However, for many of the newer series like “Nice Prison,” the available space proved fleeting. While some manga, such as Undead Unluck and Mission: Yozakura Family, were allowed to reach their proper conclusions, the majority, including Suganuma’s work, were canceled after short runs, some not even reaching the 20-chapter mark.
Impact on Creators and Readers
The high rate of cancellations can be challenging for both creators and their readership. For mangaka, it means a truncated opportunity to tell their stories, often necessitating rushed endings. For readers, it can lead to disappointment when investing time in a series that ends abruptly without a satisfying resolution. The short lifespan of “Nice Prison” reflects the intense competitive environment within Weekly Shonen Jump, where only the most popular series manage to sustain long-term serialization.
Tatsuya Suganuma’s “Nice Prison,” despite its comedic premise and efforts to stand out, ultimately had a brief tenure in Weekly Shonen Jump. Its conclusion marks another instance in a year characterized by a high volume of new manga facing early cancellations, underscoring the demanding nature of the serialization industry.
