@oldchangeling most of Isis' victims are muslim.... How the hell Isis is a muslim organization, but kills the muslims? Basically they are an imposter using Islam as a political gimmick.
We are now entering the plot of LN Vol 2. Thing is there hasn't been any new releases since Vol 2 in Dec 2018. So even if the manga is popular, unless other arrangements are made the manga will likely end its run once it finishes Vol 2.
