Its been a long time since i ever read a manga and just made me go full what the fuck, and I had read Berserk in the past which just felt whatever to me.
Nothing wrong with the author wanting to end their series after they finish telling all the story they want to tell. Always the better option compared to continue stretching on with mediocre plot.
This arc felt a little weak. The solution to the problem this time didnt feel satisfying. But Nishi is doing pretty good on his other current work in weekly jump, so i forgive them
