I agree.
The incoming death of Atri is not treated as a big deal. It was just thrown around a lot and people would just react it with 1 panel. It's now seemingly like a nature thing.
The sneak attack with the broom is so goofy. If u can one shot the robot with your stun gun, why bother attacking with the wooden broom, lol?
And then she overpowered him, it just seems so ... obvious. Like, it's a very predictable trope, I can't even get a reaction out of it.
The kindergarten incident is obviously hiding a big info. The dragging pace is not even helping.
I still want to see how it ends, but yeah, vol4 is not very enjoyable as other volumes. Wishful thinking here, but I hope vol5 is good.
