This second compilation film recaps the back half of Overlord's first season, retelling how Ainz Ooal Gown, the skeletal overlord once known as Momonga, passes himself off as the adventurer Momon. With the loyal Nabe beside him, he hunts down the Wise King of the Forest, a giant hamster he renames Hamsuke, and is drawn into events around the apothecary Lizzie Bareare and her grandson Nfirea in the city of E-Rantel. It condenses existing episodes rather than offering new material.
