Momonga is a regular salaryman who leads a guild in an DMMO-RPG known as Yggdrasil. After twelve years of playing the game, the servers are finally shutting down. Momonga logs in for the last time, seeing the game to its end. However, after the clock strikes midnight, nothing changes.

Grateful that they weren’t cast aside, the floor guardians experience the rule of their true master for the first time. Momonga quickly assess the situation and works toward protecting the tomb from invaders while contemplating what he must do.

Momonga continues his efforts to protect Nazarick from the unknown forces he may be up against in this world. As he manipulates the Mirror of Remote Viewing, he notices a village being attacked and decides to test his strength against humans.

Momonga finds that the attackers of Carne Village were Slane Theocracy soldiers dressed as people from the Baharuth Empire. As the attack to lure and eliminate Gazef Stronoff continues, Momonga takes this chance to continue his tests…

Ainz accidentally used Total Maniac on himself and panicked after regaining his emotions. Even looking at himself scares him. As he is panicking, Albedo breaks into his room, thinking he is in trouble as he did not reply her earlier, which he then gave an excuse that he was thinking about the situation in the upper floors. As he stared at her, he accidentally commented on how beautiful Albedo really is, causing Albedo to become momentarily stunned and become excitedly love struck the next moment.

Momonga sets out with Narberal disguised as humans under the names of Momon and Nabe for the city of E-Rantel. There they register to become adventurers in order to gain more information about this unknown world. As they do, evil gathers around them.

Albedo explained to Ainz that the Pleiades are requesting an audience with him. Ainz initially approved of it but when he was just 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 unique way of doing so.

While Momonga has some doubts, he accepts Nphirea Balear’s request under the condition that the members of the Swords of Darkness join them. Though her urge to kill keeps distracting her, Clementine continues to slowly find her way to Nphirea.

As Narberal was training in the Amphitheater of the sixth floor, Ainz came and complimented her. Ainz successfully convinced her that he had a reason for ordering them to converse normally with him, making him dance 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, reducing the casting time. 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. After that, they thought that they had matured more thanks to Ainz teachings, which caused Ainz to feel even more guilt and ashamed for covering his lies with more lies.

Momonga and his group continue to Carne Village. There they see that the villagers are working toward fortifying their defenses against possible future enemies. Nphirea meets up with Enri and asks her about this man named Ains Ooal Gown.

As Ainz thought about how each members of the Pleiades had unique personalities and were cute, he accidentally shouted “Game is the best” without realising it. He then thought about how in video games, you can make your ideal girl easily. Then, he saw a blotted Solution Epsilon and asked what happened. Entoma explained that Solution had 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 half acidified human out, returning back to her slim figure. In order to clean up the mess on the carpet, Entoma carried the human away from sight and ate him alive, making Ainz even more frightened.

After Momonga registers Hamusuke with the guild, he goes to Nphirea’s home to find that his client has been kidnapped. The zombified remains of the Swords of Darkness litter the storage room. And there, Momonga finds the tortured body of Ninya.

Ainz confirmed the race and classes of the Pleiades members (Yuri almost took off her collar and let 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 a scary aura sometimes, Ainz stared at Entoma and comments on how good she is at making poker faces, which Solution explained that her face is a mimic. Curious of what were the other faces she would make, Ainz ordered her to show it, which she responded by removing her mask, showing her real face to Ainz, making Ainz scream.

Momonga and Narberal begin their respective battles against Clementine and Khajit. Momonga takes this chance to learn about the mechanics of fighting in this world, but in the end, he must show Clementine the consequences of offending him.

Ainz asked for 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 excited for a second. Ainz asked for Albedo’s opinion on the matter, to which Albedo responded that she is an honest child.

Momonga finds out that Shalltear has revolted against him, due to something that had happened while she was on her mission with Sebas and Solution. The story rewinds a bit and goes over that very event. What could possibly change her loyalty to him?

Ainz was thinking about CZ’s character and wishes to strengthen his relationship with her. When he entered the Laboratory, he found out that CZ has been modified into CZ2128 Δ MK-II by Solution and Entoma (making her look like a tank). They explained that they are strengthening CZ by modifying her. While CZ had no objections, Ainz still disagrees. Solution and Entoma further explained CZ’s new feature like her Drill and the button in her back that breaks her character. Then Yuri, Lupusregina and Narberal entered the room and as Ainz was explaining how Solution and Entoma are going overboard, Solution and Entoma further modified CZ, this time they made her look like Gundam that can also fly.

Momonga does damage control at the guild while he assesses the reason for Shalltear’s revolt. Coming to the conclusion that she is under an incurable status effect, Momonga goes to the treasury to retrieve some of the powerful weapons of Nazarick.

One of the 12 executives of Zuranon, and former Black Scripture 9th Seat: Clementine. Having absolute confidence in her arms, sets out in life to escape and conceal herself from a certain magic caster. At that time, Nazarick is gathering information about martial arts under the direction of Ainz Ooal Gown. Yuri Alpha and Lupusregina Beta set out to gather information for their master which leads to a bar at Beta’s insistence. There they find Clementine drinking her woes. Lupusregina enthusiastically introduces her and Yuri to the fugitive. Clementine seeing that they are a bit strange but harmless decides to entertain them, introducing herself as Claire. She and Lupusregina get along and eventually the latter challenges the human to a drinking contest. Not willing to back down from a challenge Clementine accepts and the two women begin drinking large copious amounts of alcohol. Lupusregina manages to avoid being drunk using [Cure Poison] unbeknownst to Clementine.

Clementine awakens from a hangover to find herself in a room. After she had been killed and later resurrected, Clementine at her current state right now felt tired of being on the run from her past. Before she can go on to explain her reason, she pukes on the spot. She decides with all things as they are she should leave.

Solution Epsilon and Entoma Vasilissa Zeta come across the pub where their sisters had entered to gather information. The latter agrees assuredly and pays it a visit there.

Outside Clementine vaguely recognizes the pub, however, draws a blank and decides to go in to gather supplies for her break to the Baharuth Empire. Clementine takes notices of the two maids while as Entoma became aware of the fact that the former is watching them. Solution also takes attentive of the girl who was watching them interact. Entoma asks whether they should kill her, but Solution dismisses the idea as they are currently gathering information under Ainz’s orders.

Clementine awakens in the same room as the previous episode. She wonders why she feels so embarrassed. She begins her introduction but stops mid-sentence, feeling something is off with this situation she was in.

Back in the Great Tomb of Nazarick, Ainz Ooal Gown comments gathering information is hard. Albedo agrees stating that she will also regularly travel to the Re-Estize Kingdom to gather information. Ainz notes if it is a visit to the princess, he suggests asking Albedo maybe she can get information on Martial Arts from her.

Clementine finds the pub she was previously at in ruins. She remembers having a drink here, but that’s all. She senses something bad had happened here. The barkeep calls her out and tells her despite the wreck, they were still willing to serve drinks regardless of the pub’s ruins. Clementine asks what happened to the place, but the barkeeper breaks down mentally and cries on his knees. The fugitive thinks its best that she leave and hurry to the Empire.
