On this episode, Ainz and Albedo investigates Shalltear's mysterious condition. Later, Ainz makes plans and preparations to battle the vampire.
So it was finally nice to see World Items introduced and the Area Guardian who got created by Ainz himself. Also they revealed more details about the treasure room in the Great Tomb of Nazarick. Other than that, I'll be really looking forward for the coming battle between Ainz and Shalltear. Now what will happen next after the preparations? Overall, awesome build up an upcoming major battle.
Conclusion: Awesome build up an upcoming major battle.
