in this arc Nishi has just put up many topics in just arc and she is showing us every side just little by little like:
1. we saw iruma revive shida in the rooftop ,we only saw him revive we didn't get to see shida again then
2. the story then shifted to Sullivan meeting with shura ,where we got his last name which was huge and shura helping out baal to become demon king . then story shifted to azz and Clara
3. we saw azz character development and thought we gonna get alliance recruitment chapter but story also shifted its point after Ameri agreed to save Iruma , we didn't get to see more recruitments.
4. now the story is focusing on iruma prison stay and naberius narnia inner conflicts .
each of these events are currently not completed ,at this point Nishi is just torturing us with showing us events till only halfway to let us make theories ,i manga is currently at intense ,if anyone is binge reading couples of last arcs its peak ,but its very painful for people to waiting every week for a chapter . Nishi is just slow burning us with various things happening at same time ,near the end of this arc everything's gonna explode with so much things happening simutaneously its gonna be peak , but the wait for each ch is just killing me
