Full Summary
Sebas Tian and Solution have started to masquerade as a noble's spoiled daughter and her elderly butler in order to attract the attention of influential people and also to bait criminals into attacking them. The criminals will then be left for Shalltear who has been given the mission to capture people who know martial arts, new magic knowledge and also to gather human bodies to create undead in order to strengthen Nazarick. Upon successfully baiting a mercenary group, Shalltear proceeds to attack their hideout. Leaving some minions outside as lookouts, she enters and slaughters all who stands in her way eventually their best warrior Brain Unglaus comes forth. However, he is no match for Shalltear and is struck by pure terror upon realizing their difference in strength and he flees from her and further into the hideout. Shalltear, thinking there is no exit, lazily continues to slaughter her way through the hideout only to discover there is a hidden exit. She is then stopped by one of her minions reporting that an unknown group is approaching.

Heading out she finds an adventurer group who has been patrolling the area and decides to slaughter them as well. The slaughter is abruptly stopped when a certain female adventurer throws a potion at Shalltear, a potion which she is all too familiar with. After hypnotizing the captured Brita, Shalltear finds out about the origin of the potion and fears that she may have unknowingly disrupted Ainz's plans and it puts a huge burden on her mind. Then, she finds out that the team has left a ranger to keep watch over the place and that he should now be on his way to report about Shalltear. Agonizing over her failure to keep hidden as instructed by Ainz, she summons vampiric wolves to kill the ranger as she has no tracking skills herself. After a short while one of her minions is killed and she quickly moves to where it was slain. When she arrives she encounters a new group that she quickly notices are much stronger then the previous one. Believing that they are no match for her, she decides to simply capture them as well. This turns out to be a mistake as one of the member uses a World Item that quickly starts to take over Shalltear's mind. Unable to stop it she lashes out with a powerful attack that hits the one trying to subdue her along with another member of the group before everything goes dark.

Ainz returns to Nazarick after being informed that Shalltear has rebelled. Looking through the NPC status panel, Ainz realizes that Shalltear has been mind controlled. Since he still doesn't know where she is, he decides to find her. He seeks the help of Albedo's sister Nigredo who specializes in information magic to find Shalltear. After discovering the location, Ainz is informed by Narberal Gamma that he has been called to the Adventurer's Guild in E-Rantel. Taking the guise of Momon once again, Ainz proceeds to the meeting that consists of mythril adventurers in E-Rantel and they discuss about the appearance of a powerful vampire. Ainz insists that he will fight against Honyopenyoko alone and even argue that involving others in the fight would simply increase the number of victims.

After the meeting, Ainz heads to the forest and eventually dispose of Kralgra who not only ignores Ainz's advice but also chooses to follow him. Ainz then travels to where Shalltear is and realizes that she has returned to her previous NPC behavior which is to be on standby until someone comes too close or attacks her to which she will respond by attacking. Trying to free her from the mind control he uses Shooting Star which enables the use of the magic Wish Upon a Star three times without consuming experience. The attempt fails and Ainz immediately understands that a world item was used on Shalltear.

Ainz returns to Nazarick with the intent to go to the treasury to obtain the world items stored there. Taking along Albedo, Yuri Alpha and CZ2128 Delta the group meet up with Pandora's Actor, a personal creation of Ainz who is in charge of the treasury. Having hoped that Pandora would have the knowledge of the 200 world items, he is quickly disappointed to find out that Pandora only has knowledge of the 11 in Nazarick's control. At first, Ainz is not sure about using any of the available world items in the Treasury but he eventually decides not to since he might need them in the future. Ainz is then informed that all the Guardians have decided to attack in waves to eventually defeat Shalltear. Knowing this will certainly work but Ainz thinks that it is his responsibility to kill her and that he will do this alone. The other NPCs are strongly against this since Ainz doesn't have much of a winning chance against Shalltear. Still he has made his decision and he will go on to face Shalltear, alone..

After a long and earthshaking battle between the two, Ainz eventually comes out victorious by slaying Shalltear. Going back to Nazarick, Ainz brings Shalltear back to life in hopes that her death will release the control the enemy has on her mind. Thankfully, the resurrection does exactly that. However, there's a downside to it; Shalltear doesn't remember who used the world item on her. Thinking that the enemies might target Sebas who has been seen with Shalltear, Ainz decides to use this chance to bait the enemy to reveal themselves and orders to have Sebas' surroundings to be put under constant surveillance. When Ainz is asked about what to do with the damage inflicted to the place where Ainz and Shalltear fought, he tells Mare to leave it be as he plans to use the lie that a broken Sealing Crystal caused the destruction. He then lays out his plan to use the corpses to strengthen Nazarick's military force to which Albedo suggests using the corpses of the newly located Lizardmen as the most powerful undead created than using a human corpse who are fairly weak.

Back in E-Rantel, Momon and Nabe are both promoted to adamantite class adventurer as a show of gratitude for taking care of the vampire. Their daily exploits continue to amaze other adventurers and some even consider them the best of all adamantite adventurers. When they return to the guild to report the result of one of their quests, Ainz receives a message from Nazarick and he orders the deployment of Nazarick troops in preparation for the annihilation of the Lizardmen.
