Shueisha announced that the new Shonen Jump manga Alien Headbutt will end with chapter 16. That will arrive on May 31, 2026, and the English simulpub version will appear that day. This is one of three new series that kicked off at the very start of 2026, as it debuted after Under Doctor and Kinato’s Magic. [Thanks, Shonen Jump News and Ryokutya!] The title of the series is pretty self-explanatory when it comes to what’s going on. Ever since he was a little kid, Ouga Shirokiba dreamed of becoming a professional wrestler after seeing a video his dad had. He almost abandoned that dream after his dad died, in order to support his family, but his mom pushed him into it. After winning the world champion belt as an Ultimate Japan Pro Wrestling athlete, he headed home to Mukurojima Island to share his victory with his family. However, he arrives to find aliens invaded it. He fights one off, but becomes infected by an alien parasite. He then heads off to find his family and fight back. While this Shonen Jump manga series is about to end, there will be ways to support it in Japan. Shueisha confirmed it will compile the 16 chapters of Alien Headbutt into two volumes. Those are both set to arrive on July 3, 2026 in Japan, with the company’s official site already showing listings for both of them. It’s unknown if we’ll see Viz Media release those outside Japan. The Alien Headbutt manga will end on May 31, 2026, and the final chapter will appear worldwide online on that date. The post Shonen Jump Manga Alien Headbutt Ends appeared first on Siliconera.
