Astro Royale, one of Shonen Jump’s more promising recent series, appears to be nearing cancellation. While there has been no official statement yet, recent publishing details strongly suggest that the manga’s days are numbered. For fans, this comes as disappointing news, but the warning signs have been hard to ignore.
The biggest indication of trouble is the announcement that Astro Royale’s fifth volume will only contain 168 pages, well below the standard 192 pages. This suggests that Shonen Jump’s editorial team is adjusting the volume’s length to extend the series’ presence in the magazine before it ultimately concludes. If this pattern holds, Astro Royale is likely to wrap up around issue 20 or 21, though there’s a chance it could last until issue 24 if the final chapters are split strategically.
The Clues Point to an Early End

Shonen Jump rarely alters the page count of ongoing series unless a cancellation is imminent. The decision to shorten Astro Royale’s fifth volume is a strong sign that the series is being quietly prepared for an exit. Adjusting the volume’s length allows the editors to prevent Volume 6 from being too thin, which is a common practice when a series is in its final stretch.
Astro Royale’s early end is likely due to underwhelming popularity or weak sales. Shonen Jump is notoriously ruthless when it comes to cutting series that fail to meet expectations, regardless of their creative potential. The magazine’s competitive nature means that new titles are constantly introduced, forcing struggling series to make way. Sadly, Astro Royale seems to be the latest victim of this system.
How Much Longer Will Astro Royale Last?

Initial speculation suggested that Astro Royale would end around issue 20 or 21, but some industry sources now believe it could extend to issue 24. If the editors decide to stretch out the remaining chapters, the series might last a bit longer before wrapping up. Shonen Jump has been known to allow some series extra time to conclude their stories more naturally, but that doesn’t change the fact that Astro Royale’s cancellation seems inevitable.
Even if Astro Royale does make it to issue 24, the underlying signs remain clear. With Shonen Jump’s one-shot project ending soon and the upcoming double issues on the horizon, it’s unlikely the series will survive beyond the current batch of ongoing titles. The best hope for fans is that the creator will be given enough time to craft a satisfying conclusion rather than being forced into an abrupt ending.
Astro Royale’s fate serves as yet another reminder of how competitive the Shonen Jump landscape can be. Even promising series can face early cancellation if they fail to capture a strong enough audience. While Astro Royale may not have secured a long-term spot, its creative run will still be remembered by those who followed its journey from the beginning.
