Detailed Summary (Spoilers)

Sebastian and Solution has started to masquerade as a noble daughter and her butler in order to attract influential people and also to bait criminals into attacking them. The criminals are to be baited for Shalltear who has been given the mission to capture people who knows martial arts, new magic 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. He is however no match for Shalltear and is struck by pure terror upon realizing their difference in strength and he flees further into the hideout. Shalltear knowing there is no exit lazily continues to slaughter her way through the hideout until she is stopped by one of her minions reporting an unknown group is approaching.

Heading out she finds an adventurer group who is patrolling the area and quickly decides to capture them as well. After their capture she finds out that they had left a ranger to watch out for trouble and that he has now started to return 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. However believing that they still are no match for her she decided to simply capture them. This turns out to be a mistake as one of the magic chanters uses an item that quickly starts to take over Shalltear's mind realizing her mistake but with no way to stop it she lashes out with a powerful attack that hits the brain-washer along with one more person before everything goes dark.

Ainz having returned to Nazarick after being informed that Shalltear has rebelled finds out through the NPC status panel that she has been mind controlled. Since he still don't know where she is to find her he makes use of Albedo's sister Nigredo who specializes in information magic. He then travels to where Shalltear is and finds her out she has returned to her previous NPC behavior which is to be on standby until someone comes to close or attacks her to which she will respond by attacking. Trying to cure her from the mind control he uses the magic item the 「Shooting Star」 ring, which enables the use of the magic 「Wish Upon a Star」 three times without consuming experience. But unfortunately Wish Upon a Star failed. Seeing as the only reason why the magic of Wish Upon a Star would fail would be only if a world class magic item was used.

Ainz returns to Nazarick to go to the treasury in hopes of finding out. Here we are introduced to Pandora's Actor, Ainz created NPC who is in charge of the treasury. Having hoped that Pandora had knowledge of all the 200 world class item's he quickly finds out that Pandora only has knowledge of the 11 that is in Nazarick's control. Disappointment at this Ainz starts to contemplate if he should use on of the items to stop Shalltear or not but eventually decides not to since the price to use most of the world class items would be his own life. Ainz is informed that all the Guardians have decided to attack in waves to eventually defeat Shalltear. Knowing this would work Ainz still decides that it is his responsibility to kill her and that he will do this alone. The other NPC's are strongly against this since Shalltear being the strongest of all the guardians not even Ainz has a high chance of winning alone against her. Still he decides to go through with it and goes alone to battle her.

Before going to battle he decides to take advantage of the situation and get's himself hired by the adventurer union to stop Shalltear. After a long and lengthy battle between the two, Ainz eventually comes out victorious having slain Shalltear. Going back to Nazarick, Ainz brings Shalltear back to life and hoping that her death would cure her mind control which it thankfully has. He then get's into a talk about how to further strengthen Nazarick and get's told that they should gather stronger bodies since with a humans body they can at most create a level 40 undead and even then it is a fairly weak level 40. So to get stronger undead, they should attack and annihilate the Lizardmen community that was recently discovered. Ainz and Narberal are also promoted to the highest rank an adventurer can hold after reporting on Shalltear's defeat.
