Since I don't read the original novel, so, I don't know it was already this show pace or it is just the manga adaptation that's slow (just like Arifure) but this is just getting more and more boring. I don't even know whats the point of this story anymore.
It started with the interesting ideas but now it turned into a generic boring Isekai. This chapter, for example, is seriously pointless since these characters have been ignored for very long time -- to the point that I thought they have nothing to do with the story anymore. But why introducing them now? I don't think anyone cares about them anymore at this point.
