Have in mind that the last 5 or so chapters where made with the knowledge that it was going to be cancelled.
Either way, I thought the series was pretty mediocre overall, it had some interesting poins, but honestly, with Kimetsu no Yaiba, Chainsaw-Man and Jujutsu Kaisen, we already had a bunch of Demon Hunting manga at the same time in the same magazine, so it's natural at least one of them would be cancelled and Yaiba and Kaisen are selling decently well apparently, and Chainsaw-Man is at least unique in it's delivery, like it or not.
