I find the characters really interesting and fun. I was hoping that the series would be about Ainz making the guardians more human. I thought that was what they were doing with Sebas saving that girl and Cocytus wanting to save the lizard people. But it seems like this series is instead about Ainz becoming inhuman. I find his loneliness and complete incompetence to be sad character flaws I was hoping he could overcome, but it seem like he is instead digs himself deeper.
