Plot
Ainz accidentally uses the magic item Total Maniac on himself, allowing him to regain his emotions and leaving him in a bewildered state. He tries to pretend that everything is fine. But then the battle maids, Pleiades, have arrived before him and wait to receive their next orders, buuut...!

Play 1 - Overd and Beginning
Ainz accidentally used Total Maniac on himself and panicked after regaining his emotions. As he is panicking, Albedo broke into his room, thinking he is in trouble, which he explained that he is asking about the situation in the upper floors. As he stared at her, he accidentally commented on how beautiful Albedo is, causing Albedo to become excited.

Play 2 - Battle Maids
Albedo explained that the Pleiades are requesting an audience with Ainz. Ainz initially approved of it but when he was about to refuse by saying he doesn't feel well, Albedo immediately left the room and called the Battle Maids. When the Pleiades arrived, he ordered them to converse to him normally so they won't notice that he is panicking, which the Pleiades agreed, although each of them have their own way of doing so.

Play 3 - Cutting Through the Lies with Fists
As Narberal was training in Amphitheater, Ainz complimented her. Ainz successfully convinced her that he had a reason for ordering them to converse normally with him, making him danced happily. As Narberal asked what he is doing, he made an excuse that his dance is a new magical pose that only he knows of and that pose allows him to cast magic faster. Fascinated, Narberal asked him to teach her the magic pose, which Ainz had no choice but to agree. As the two of them danced, the other Pleiades arrived and joined the dance.

Play 4 - Two Victims
As Ainz thought about how each members of the Pleiades had unique personality and cute, he accidentally shouted "Game is the best". He then thought about how in video games, you can make your ideal girl easily. Then, he saw a fat Solution Epsilon and asked what happened. Entoma explained that Solution swallowed a human whole and is currently torturing it with acid. Frightened because of the fact that Solution is dissolving a human inside her, Ainz ordered her to return to her original form and she spit the human out, and in order to clean it, Entoma ate the human, making Ainz even more frightened.

Play 5 - A Predator's Heart
Ainz confirmed the race and classes of the Pleiades members (Yuri almost took off her collar and letting her head fall off in the process). He then asked how the Pleiades didn't show much expression, which Yuri replied that they are still nowhere near Ainz's level. While Lupusregina, CZ and Narberal spoke of how Yuri can emit scary aura sometimes, Ainz stared at Entoma and comments on how good she is at making poker face, which Solution explained that her face is a mimic. Curious of what other face she can make, Ainz ordered her to show it, which she responded by removing her mask, showing her real face to Ainz, making Ainz scream.

Play 6 - Battle Outside of Carne Village
Ainz asked the purpose of the Pleiades seeking an audience with him. Yuri explained that Lupusregina wanted to report to him of her mission in Carne Village and would like to use this chance to greet him. Yuri also commented on how Lupusregina didn't seem to understand her mission, which Lupusregina responded that she knows this and that about Carne Village, including their "Night Activities", making Albedo got excited for a second. Ainz asked Albedo's opinion on the matter, which Albedo responded that she is an honest child. At that comment, CZ make a skeptical response while Solution and Entoma make a sarcastic comment. Narberal also commented that her cheerful girl image is fake. Yuri told them to behave and Ainz decided to trust Albedo's judgement. Lupusregina then added some sex jokes while saying she will work hard, causing Ainz to laugh. Albedo got jealous that Lupusregina made Ainz laugh and their conversation soon escalated to a boasting competition about who can eat the biggest amount of meal.
