First chapter I was like, "is it Overlord clone? Maybe. But Overlord has some generic elements itself, so maybe it's just coincidence. Let's give it the benefit of the doubt"
Then Ms. NPC-second-in-command here gets the crazed, zealot look and I was like "yep, hey Albedo, nice to kinda see you again."
I'm an Overlord fan though so I'll bite.
