@Alvian_kisna_asyari As I see it, The Underworld remains in different realm, but as this happens Overlord world, the focus is on living world, and no one cannot enter to Underworld without dying first. Since even Ainz cannot awaken Arayashiki.

To be honest, I prefer The Underworld, which has a Saint Seiya story, as the protagonist's headquarters compared to the Nazarick tomb. Because The Underworld looks more extraordinary than the Nazarick tomb.

@Alvian_kisna_asyari Though I need to nerf these three (Thanatos, Hypnos and Hades) Since Ainz would seem like insect if I kept the correct scaling.
