Review Detail of ishtarin in Overlord: The Origin

I don't mind giving this novel a decent review because in my opinion it doesn't deserve the name "Overlord" as it has nothing to do with the anime where the new world, I'm tired of waiting for the anime canon to start, I understand that you want to give some immersion in the story but it's too much and it's better that I make a new story that is not "Overlord". (Don't pay much attention to me I'm just one person expressing their frustrations because I was expecting an Overlord novel not one of the game "Yggdrasil" In short, this is written with a translator in case it finds faults, without commas and without periods it is due to laziness.)
