Different publishers which means different standards and requirements for continuing. Usually the more popular the magazine the more strict it gets... for these jump magazines it gets rough as hell, live or die by weekly polling. I think everyone by now has multiple series that have gotten axed by shueisha they can't forgive. (My biggest peeve is Double Arts, same magazine as this one).Ngl, deadass how come mangas like this get axed but shit like Rent a girlfriend and hajimete no gal get a stupid amount of chapters
