Apparently it was the mangaka’s own decision to end the series. Pretty sure it’s consistently one of Ganma’s highest rated series so they probably wouldn’t axe it.
This was good and all, but I also kind of hate when things end this way. It's like, "Our story is just beginning..." and then nope, if there's no sequel or anything, that's the end there buddy. Don't be such a tease.
