I have no idea why ya'll keep comparing it to Overlord.
In essence, Overlord is a story where the MC completely blended into the role of a ruler. This MC however, shows many signs of immaturity and weakness, at almost no point in the story does he ever have the dignity of a ruler. It's to the point it makes no sense that anyone is willing to follow his command, especially after that elf arc, where he acted like a shy little boy after being fawned at by a local.
It also doesn't help he constantly explains how utterly weak and helpless he is...A better example to compare it to, would be Mynoghra. But that, too, has too many things going on for it to be compared to this thing.
I really don't understand why quite talented artists end up being hired to work on these completely milquetoast projects that are doomed to fade into obscurity.
