User blog:Disfigure/Regarding Evil Lord Wrath's role in Volume 12

Yes, Maruyama has confirmed from his blog that Evil Lord Wrath rather than Demiurge (Jaldaboath) who later join in the battle against Remedios, Calca, and so on. During the middle of the fight, Demiurge did switch places with Evil Lord Wrath to fight in his stead. It happen when Remedios's attack on Demiurge threw him away to the house is where it all begun. As the house collapses, I assumed this gave Demiurge time to pull off do something like that with the Holy Kingdom's soldiers.

Maruyama said that in Volume 12, Jaldabaoth was cosplayed by A-san and B-san and if you know who was B-san then you must've spend lots of money on overlord (referring to those who brought the BD box set that included a concept art book and Wrath's character design was in it. (Information obtained from a reddit user, Vulpix0r on r/Overlord).

Also, remember one of the illustrations from Volume 12 depicting a large demon in flames? That is Evil Lord Wrath.
