The Darkness of the Capital and the Butler of Steel (王都の闇と鋼の執事) is a re-enactment game event in Mass for the Dead that was released on August 30, 2019 to September 9, 2019.

Background
This is a story you should have seen somewhere--. Behind Sebas's assault on the "Six Arms" hideout to save the kidnapped Tuare, a plan has begun in which the Demiurge has full control. This night, the flames of Gehenna attack the royal capital.

Summary
A large carriage is running against the background of the fortress city of E-Rantel. Riding within are Sebas Tian, Solution Epsilon, Shalltear Bloodfallen and her two Vampire Brides. The group have a brief discussion on their creators and Ainz, until they are disturbed by a commotion outside. Death Spreading Brigade has surrounded them and are excited at seeing Shalltear. However, their excitement becomes horror after Shalltear and her vampires begin slaughtering the bandits. Solution catches the driver of the carriage, Zach, who she consumes into her body. Shalltear and her minions later take their leave from the group to track the bandits and their lair.

Later Sebas Tian who has successfully infiltrated Re-Estize is seen walking in the alleys of the royal capital. As he is walking through the alleyways he spots a man throwing a sack out the door of his establishment. The man walks back into his house, but Sebas Tian thinks its wise not to get involved, so he begins to walk around the sack. A badly bruised injured person grabs his ankle, forcing his attention. Sebas Tian sees that it is a woman that is inside the sack, politely asks her to let go of him. When he is met with silence, he then asks if she needs assistance. The man who threw the sack out comes back and asks Sebas what he is doing. Irritated, Sebas pockets his scroll to then grab the man by the shirt, demanding to know who the woman is. The man states that she is one of his employees, but Sebas doesn't believe him due to the extent of the woman's injuries. Sebas decides to take her with him, but the man protests by saying that if Sebas Tian takes her, then he'll be killed by the criminal organization called Eight Fingers. Remembering his creator's motto, Sebas gives the man money to flee the country before taking the woman with him back to the mansion.

Back at the mansion, Solution greets Sebas and notices that he is carrying a human. She asks Sebas about the severely injured woman and he says that he found her and asks Solution to assess her condition. Solution inquires why he did not simply leave her for the temples, he makes an excuse and still has her treated. Sebas leaves Solution to her work, wondering why he saved the woman and if Touch Me's lawful good view of helping people is a curse or not. Sometime later, Solution returns and tells Sebas that the woman has syphilis and two other diseases, several cracked ribs and fingers, tendons in her arm and leg torn, her teeth had been forcefully pulled, an anal fissure, and that she may be addicted to some form of drug. Sebas asks Solution to heal the woman, who also asks if it is alright to call Pestonya Shortcake Wanko. Sebas refuses telling Solution to use the healing scrolls she possesses. She hesitates at first, but ultimately complies and asks if Ainz should be notified, to which Sebas refuses to do. Sebas leaves to go buy food while Solution heals the woman. Solution notes that she could eat her before Sebas returns, but she ultimately doesn't do it out of duty.

When Sebas returns with food, the woman is awake and fully healed. Sebas serves her the food which she thanks him for and eats quickly. Sebas informs the woman that he will protect her and comforts her when she cries. He then asks for her name. She says her name is Tuare and Sebas gives her his name. Sebas leaves to give Tuare time to rest. He encounters Solution in the hallway who asks if there will be any problems regarding Tuare but Sebas says he will handle any that comes their way. Meanwhile, the Eight Fingers hold a meeting and discuss their business. Cocco Doll, head of the slave trade, asks Zero to do a task for him. He asks Zero to retrieve a woman who was supposed to be disposed of which Zero accepts.

Sebas Tian returns to the mansion and is greeted by Tuare serving as a maid. He asks her what is for dinner, she says stew and potatoes. Seeing her nervousness Sebas assures her that her cooking is delicious, causing her to blush. Solution Epsilon asks Sebas if they should inform Ainz that they have accepted a human as a maid, to which he rebuttals not to inform their master of their new addition, citing it to be frivolous news. At the end of their conversation, the mansion front door is knocked on by two strangers.

The two enter the mansion and introduce themselves as Staffan Heivish, a patrol officer of the law and Succulent, who is a representative filing a complaint against Lady Solution. Solution nonchalantly retires and orders her butler to handle it. During the talks, it’s learned that Succulent is a representative of the brothel that claims that Sebas kidnapped one of their employees. Stafan holds Sebas as guilty for the thief despite the circumstances of the girl’s condition at the time. He offers clemency, but it is merely more extortion of money. He warns Sebas that he will have one day to return the girl to Succulent. After they leave Solution asks how will he wishes to proceed, Sebas replies that he wishes to take a stroll. Once Sebas leaves the mansion, Solution decides to call Ainz. She reports that Sebas Tian may have gone rogue and confirms she has evidence to prove it.

Meanwhile, Brain Unglaus who survived his encounter with Shalltear Bloodfallen manages to reach Re-Estize before tucking himself in an alley sitting pitifully in the rain. He is found by his old rival Gazef Stronoff who was surprised to find such a skilled swordsman acting suicidal, wanting to keep him alive. There after Brain fully rested he learns of his defeat by the vampire. Brain then tells Gazef that there are things stronger than both of them and begins to leave. Hoping that Brain would join the Kingdom, he offered Brain a place at his house and to pay for his expenses until Brain knew what he wanted to do. Brain in gratitude decided to accept Gazef offer before taking a walk to clear his head. The scene switches to Climb training. He is joined by Gazef Stronoff who offers to spar with him. Gazef mentions he wishes to savor some time with a friend as if it weren't for a merciful magic caster, he would not be present to spar with Climb. Gazef tells Climb the name of Ainz Ooal Gown for the young bodyguard to commit to memory. The two parry blades with each other, however, Climb is no match for the Warrior Captain, becoming exhausted in the end. Climb is told he lacks talent but should continue to gain experience. Climb arrives at Renner’s chambers where he finds her drinking tea with her friend, Lakyus Alvein Dale Aindra. An issue has come up with the last underground brothel, which Renner proposes that Blue Roses target it, however, Renner is hesitant to include Climb in danger. Lakyus asks Climb to inform Tia, Evileye, and Gagaran of their findings. Climb heads to the inn where Gagaran and Evileye are staying at. He informs the duo Lakyus wants both of them to mobilize for a raid on a brothel housing slaves. Climb wishes to be capable of more strength someday, but Evileye advises him to go his own pace, and not to lose his humanity in pursuit of power.

In the streets a group of drunk men assault a boy for simply bumping into them. Sebas Tian intervenes and when they refuse to disperse peacefully he knocks them out in a matter of seconds. Leaving the scene the butler goes into an alleyway, where Climb follows enthusiastically asks Sebas for a quick lesson in strength after witnessing him recently. Sebas examines his hands and sword, noting it is the young man's reserve weapon due to a slight ding on the blade edge. He sees Climb as trustworthy and decides giving him a lesson: how to overcome fear of death. By flooding Climb's sense with killing intent, Climb dodges at the last possible instance by overcoming his fear, by thinking of Renner. Sebas congratulates Climb for surviving, as the shock alone would have killed him. When Climb asked who Sebas was, he merely said he was an old man who knew how to handle himself. Sebas, wanting to give another lesson, is interrupted by a panicked Brain, who having witnessed this around the corner, is moved by Climb's ability to overcome intense fear, and asks to also learn from Sebas.

However, the trio are beset by five assassins sent by Succulent. Sebas downs three of them alone, leaving the last two to be handled by Brain and Climb. The young duo notes that Sebas' strength is incredible, maybe even beyond the power of Brain and Gazef combined. Sebas uses their fight as a teaching moment to instruct Climb to be aware of his fear to keep himself alive, but not be dictated by it, and the boy musters strength to use the Martial Art: Slash to incapacitate the last standing assassin, whereas Brain finished moments earlier. With their attackers downed, Sebas uses a skill to easily interrogate one of them on where to find Succulent and Eight Fingers. Climb is sickened to learn criminals are finding loopholes in the law to keep slaves, and wishes to aid his new comrades in storming the hideout. The trio move together out of a grown respect for each other, and they head for Succulent's brothel which happens to be exactly the same place Sebas rescued Tuare from.

Sebas Brain and Climb arrive at the brothel and use two entryways: the front door to the main brothel, and the side entrance to the underground storage area. Climb and Brain take the latter door, while Sebas charges the front. Sebas forewarns the duo that if needed, he will kill the opposition inside. They both understand, only asking that the leaders of Eight Fingers, Cocco Doll and Succulent must be captured alive.

Sebas easily removes the steal door, knocks away the guards, and comes across Staffan Heivish, mercilessly assaulting a slave girl for sexual pleasure. Upon seeing the gruesome sight, Sebas intensely slaps Staffan into a bloody state, and after the Constable pleas for mercy with money, Sebas concludes that he is unworthy of life and kicks him in half.

Brain and Climb locate a trap door (courtesy of items by Gagaran) leading to the underground storage. While Brain scouts further, Climb stand watch, but encounters Coco Doll and Succulent arrive by a hidden passage in front of the him. Succulent uses his illusion magic to gravely injure Climb, until Brain returns. Succulent seeing Brain recognizes him and tries to offer him a place in the syndicate, but is turned down. Faced with opposition Succulent challenges Brain revealing his illusion technique.

The battle is over in an instant as Brain defeats Succulent with his God Slash Technique. The trio are successful in apprehending the two members of Eight Fingers, and return to their respective homes after giving the criminals to the proper authorities. Late at night, Zero gathers the remaining members of Six Arms, to search the perpetrators of the raid on the brothel for opposing the Eight Fingers. Brain returns to Gazef's home and the two have dinner, discussing Climb's progress and Shalltear Bloodfallen. Sebas returns to the manor, only for Solution to be in her Pleiades attire, telling him that Ainz is waiting for him inside. Before Ainz Ooal Gown, who has brought with him Demiurge and Cocytus. Seeing Sebas sweating, Ainz tosses a handkerchief to his feet. Solution Epsilon brings Tuare per Ainz's orders. Demiurge readies to use Controller Magic on her, but Ainz permits her to stand of her own will as she is brave enough to look Ainz straight in the face. Given that Sebas was ordered to be discreet in his information gathering but has brought unwanted attention, Ainz will forgive him if he kills Tuare. Stunned by this order at first, he seriously attacks her as she readies herself for death and fully trusting of him. Mid-attack, Cocytus blocks him as this was a test, confirming to Ainz that the attack was unquestionably a killing blow as ordered, proving Sebas' loyalty is unfeigned. Determining that enough information was gathered, Ainz declares the mission complete and vacates briefly to Nazarick.

Outside the room Sebas does not offer an apology to Tuare, instead offering to petition his master for memory alteration magic for her to live peacefully among humans. However, she does not wish to leave, as her life was small and difficult. Even growing up, she was always hungry as the feudal lord of her land took most of the crops grown, leaving her people with next to nothing. But serving under him and his kindness, she wants to continue as a maid so long as she can still be with him. Sebas then decides to ask Ainz to allow Tuare to continue under his care as a maid in Nazarick, but only if she has no human world attachments. Tuare's only attachment is her little sister. Sebas goes to petition Ainz, and before he goes, Tuare kisses him.

Sebas returns to the meeting room, teased by Demiurge for his flushed face. Ainz returns, asking if Demiurge is satisfied by the test. As Sebas wanted to overwrite her memories, Demiurge proposes killing her for making certain no knowledge of them is leaked; which is rejected by Ainz, not wanting to kill needlessly with nothing to gain from it. When discussing where to have her, Sebas opts to have her serve as his maid- stunning the others in the room. As Sebas pleads his case, Demiurge is quick to point the negatives of his decision and as they argue, Momonga remembers Touch Me and Ulbert Alain Odle arguing over which mission with the best drop rate to take on. Returning to the present, Cocytus interjects that the both of them stop arguing in front of Ainz, but he is happy for this nostalgic bickering. As he laughs, the same aura that quells him asserts, and he calmly asks for Tuare to return to pass his decision.

When seeing her resemblance and hearing her full name, Ainz asks if she desires to move to the great tomb- she would if Sebas were there. Ainz decides she will be a provisional maid, removing Sebas as the Pleiades Leader, and activate Aureole Omega to take over. All sentries withdraw and Tuare is granted the protection of Ainz's name.

The next morning, Sebas and Solution are off to acquire the grain for Demiurge, leaving Tuare alone to tend to the mansion. By day's end, Sebas and Solution return to the manor, finding a note by Six Arms that states that they took Tuare to their base, demanding Sebas come alone. Solution reminds Sebas of Ainz's decree, and the Pleiades message their master. As Ainz is preoccupied, he relays to Albedo to send support to Sebas. While she questions saving an inferior being like a human, Ainz had promised her his protection in his name, and demands support; Albedo relents and moves to send reinforcements for Demiurge to command onsite. After communications to Ainz end, Albedo privately remarks her thoughts that his renaming of himself after the guild is ridiculous. The guild flag lies on the floor, having been replaced on the wall by the original Momonga banner. Demiurge gathers the Pleiades, Mare, and Shalltear. Sebas, not part of the majority of the plan following the rescue of Tuare, leaves the room for them to discuss their mission for destroying Eight Fingers.

Climb and Brain now part of a part force to supress all of Eighy Fingers bases, team up with a former adventurer named Lockmeier. He deactivates his invisibility to give a report: five members of Six Arms are inside, and a girl is held captive in a cell. Due to Six Arms being present, the group believes they should fall back, but stop as they see Sebas arriving. Both parties explain their situations and adjust the plan: Sebas will directly handle Six Arms and focusing the security to the front door, while Climb, Brain, and Lockmeier covertly infiltrate the stronghold. Brain, Climb and Lockmeier find Tuare in a holding cell, but Brain's instincts have him on edge. When they round a corner, they are trapped by Zero himself, who downs Lockmeier with a punch to his chest. Seeing Brain in person, knowing Succulent was outclassed, Zero offers mercy if Brain kneels and serves Six Arms. Brain deals with Zero but informs Climb and Lockmeier that Tuare is really Succulent using illusion casting. As Brain fights Zero, his blade is deflected by Zero's fists due to the latter's Monk Class. With Succulent using illusion clones, Lockmeier uses an item to reveal the real one so Climb can attack. Climb uses his own martial art he learned from his training with Sebas and overpowers Succulent.

As Sebas enters the front gate, he is welcomed by four, not five, of the remaining Six Arms. Surrounded by Eight Fingers subordinates with their rich patrons viewing tonight's entertainment overhead. Sebas asks if Zero is up there, and when they affirm it, Sebas points for Solution to scout the balcony. Six Arms, misinterpreting this gesture, state it will do him no good as they will make him suffer, whereas Sebas counters that if they attack him at all once they may survive at least ten seconds. As they introduce themselves, Sebas is immediately angered by Davernoch's title of "Undead King" and prepares to punish him.

Back to Sebas, he instantly blows Davernoch's head off; following with decapitating Edström, and punching Peshurian's head clean off, and finally killing the frightened Malmvist. Causing a fright amidst the Eight Fingers subordinates, Solution relays to Sebas that Zero is not among the partons on the balcony, and Sebas gives himself another ten seconds to slaughter the henchmen.

Zero, displeased by Succulent's loss, offers a more powered battle with Brain; both use their strongest techniques, but Brain's God Slash and Whistling Wind require him to be still in a circle whereas Zero can punch the air for an attack. As they dialogue, Sebas arrives, shocking Zero who is in disbelief that his subordinates could have lost or the butler getting as far as he did without any damage. Climb informs Sebas the Tuare they found was a fake, but the real Tuare is behind Sebas. Enraged, Zero pauses his battle with Brain to fight Sebas, using his strongest Monk attack to strike Sebas's center mass. Sebas is unfazed, while Brain, Climb and Lockmeier are left speechless by such a powerful fortification from the butler. Sebas nonchalantly counters with a drop heel kick, caving Zero's head in; his dying breath in asking who Sebas really is. In order to relieve suspicion from the trio, Sebas mentions he is "just the slightest bit stronger" and the group moves on.

Back in Nazarick, Pestonya introduces Tuare to the Homunculus Maids as a new recruit. Sebas reminds Pestonya to have Tuare's training be accommodating to her human status; Pestonya acknowledges, stating her maid status is temporary until she marries much of the butler's discomfort.
