I re-read couple times due confusion.
- The guard head become flat head that looks like a sphere if you see it from above (kinda like Fla tEarth things).
- So the corrupted luzeffle are not luzeffl, so who is this winged demon?
Right, this is what i think.
Maybe Bobby is referring to that guy all along, it was a male name after all.
Maybe "weakling" is a byproduct of bobby and she actually follow bobby instruction while Bobby is loyal to Luzeffle
Drifter is right. The reason booby is commited to being enslaved is because she thinks she deserved that punishment. It has been stated a few chapters ago.
Now about that last dude.... yeah im confused too.
