This is a fanfiction of "Overlord" and follows the events of the original Volume 11. Jaldabaoth attacks the Holy Kingdom, who in turn have no choice but to ask the Sorcerer Kingdom for help. Ainz accepts and has a showdown with Jaldabaoth. Who will win? You might be surprised :) More sasuga, more keikaku, Demiurge approves.
I originally wrote it at the end of 2016, now I've edited and completed this volume.
