CZ2128 Delta (シーゼットニイチニハチ・デルタ/CZ2128・Δ) AKA "CZ" is an automaton battle maid and a member of the "Pleiades Six Stars," the battle maid squad of the Great Tomb of Nazarick. She was created by Garnet.


CZ Delta is a girl who is short in stature and has red-gold straight long hair. She wears an eyepatch over her left eye, while her right eye has an emerald color and target-mark on the pupil. Her face is very delicate, it looks as if it was artificially crafted by hand. She wears accessories with military camouflage patterns. While her face is beautiful, she does not show her emotions and talks in a flat tone.

Her attire is similar to that of Narberal Gamma and Yuri Alpha. However, the biggest difference between her attire and theirs are her urban camouflage accessories and the cute sticker attached to a corner of her skirt with '1 yen' written on it. The other significant difference is the white gun she often has holstered on her waist similar to how one would wear a sword.


CZ2128 Delta appears emotionless and has a silent nature. Her Karma is relatively high, which makes her, along with Yuri Alpha, one of the two "safe" Pleiades to humans. Though she usually ignores conversations from humans, sometimes there is a possibility to communicate with her.

CZ2128 Delta hates cannibalism, but likes cute things, such as Eclair Ecleir Eicler. At the same time, she also takes pleasure in hugging the struggling Eclair like a doll. She often hugs things she finds cute until someone of authority tells her to let go. She also pastes a One-Yen Sticker on the things that she likes.


CZ2128 Delta was created by Garnet to be one of the battle maids, the Pleiades. They served as a last line of defense against intruders. However, because she is unlikely to be able to stand against enemy players who managed to come this far, her only real purpose was to distract the invaders until the guild members of Ainz Ooal Gown were able to fully prepare for their final stand in the throne room.

As Garnet was responsible for the design of the Treasury's security systems in Nazarick, along with Tabula Smaragdina. Thus, CZ2128 Delta's character settings were set to be familiar with Nazarick's mechanism unlocking methods. CZ's knowledge of those mechanisms had been part of the backstory her creator had made for her.

She is the most popular member of the Pleiades among the Homunculus Maids. The Homunculus Maids even fight among themselves to sit next to her and some of them even want a hug pillow of her.

Main article: The Paladin of the Holy Kingdom Arc

There, she will shoot her magic bullets at Ainz, disrupting him from successfully casting his spells.[11]

Later not long after Ainz supposedly falls in battle, CZ shows up in the Holy Kingdom's Liberation base of operations, now supposedly under the Sorcerer King's direct authority. As a security precaution, she is put in chains and placed under house arrest in one of the abandoned noble houses. It is around this time that the Zern representative, Beebeebee, comes to request the humans to liberate their prince in return for their co-operation. Prince Caspond uses this as an opportunity to test CZ's supposed loyalty. He hopes to increase their chances of success and appoints her to work with Neia Baraja on rescuing the prince and liberating the city of Kalinsha. After getting to know each other and easing the tense situation between the two, both Neia and CZ decide they will carry out the rescue together and start to form a bond over their loyalty to the Sorcerer King.

The two infiltrate the demi-human occupied city of Kalinsha through the Zern help by hiding inside of barrels which are covered in meat to hide their scent. After they reach the base of the castle, they climb up the walls and reach the room that was prepared by the Zern by having a rope tied to a cupboard so they can reach the room underneath. Thus they carefully infiltrate the inner halls and reach the prince's room, which is guarded by two very powerful [Vah Uns. After a bit of long struggle, they are both defeated, one at the guard station and one when they were crossing the walkway. Then they meet with the Zern prince, Beebeezee, and inform him about the Zerns. After he is informed that they came to his rescue and that his father, the king, has been killed, he immediately goes with them to meet the other Zerns to figure out what to do next.

When he is discussing their future with other Zerns, Neia suggests they go to the Sorcerer Kingdom as refugees, which surprises both him and CZ. After some deliberations, they decide to go along with her suggestion; only to learn that one of the three demon commanders will arrive in their location shortly. It is then decided this will be their chance to take out one of Jaldabaoth's commanders and cripple the alliance organization. So CZ, Neia, the Prince, and his followers join forces to battle the demon and win.[12] Thus, they later ensure victory for all parties involved; with the city of Kalinsha re-captured and both CZ and Neia become heroes for their success in the operation.

CZ continues to support Neia as she uses her new fame to form the Sorcerer King's Rescue Team and helps her with various works. When the final battle at Prart begins, she is seen at Neia's side to also protect her. Their team battles the demi-human force alongside the rest of the Holy Kingdom Liberation Army. Once Ainz puts an end to Jaldaboath's terror through killing the demon, they cheer on and congratulate him for his victory.[13]

After bidding farewell and saying goodbye to Neia, CZ returns with Ainz to the Sorcerer Kingdom. When Ainz asks about her relationship with Neia, she agrees that they are friends.[14]

Mass for the Dead Arc

Main article: Mass for the Dead Arc

After Nazarick was transported to the New World and was left in ruins, CZ worked with the other Pleiades to restore Nazarick to its former glory. Having been recently revived CZ and the battle maids lost several of their levels and it would be some time before they were at full power. Still CZ and her sisters were committed to their duties and were the first NPCs to do a survey of the Crack on the 10th Floor, gaining vital data on its cycles and the Chaos Beasts.[15] The automaton would also make a trip with Momonga, Albedo and Yuri to the Treasury to access any damage it might have incurred when Nazarick was attacked. Thankfully the treasury was spared any damage as it existed in a separate space. There she met Pandora's Actor and nearly attacked him after he tried to impersonate Momonga.[16]

CZ2128 Delta with the rest of her sisters greeted Narberal Gamma upon her return from the outside world. From the doppelgänger she gained some insight on human society and started practicing on how to communicate with them by referring them as "maggots". It gained some attention from Sebas Tian and Momonga who intervene to correct some misconceptions and focus their training on hospitality.[17] CZ would assist Yuri in cleaning up the piles of debris left on the 6th Floor. After some discussion with her and Entoma, the trio decided it would be best to crush all the piles into sand for easier storage.[18] Overtime CZ began to suffer some distress over her being brought back to life and also the decrepit state of Nazarick. It only was made worse that many of her favorite animals that she went to for comfort on the 6th Floor were dead. However she brightened up when Demiurge talked about a mission to capture some "sheep". Eager to pet some fluffy animals, CZ volunteered to capture the "sheep". Everything was fine until the automaton found out the "sheep" were humans that wandered to close to Nazarick, causing her mind to freeze at what they were doing. Brought back to Nazarick, the automaton's mind was at a still, and had to be coaxed back to reality after Momonga used a Spear Needle summoned from Ashurbanipal.[19]

The automaton maid would assist Yuri and Entoma Vasilissa Zeta in cleaning several piles of discarded debris on the 6th Floor by smashing them into sand and stored for later use.[20] While cleaning the 6th Floor, CZ got into an argument with Entoma over who was the older sister among the two. To determine who was eldest the two Pleiades maids competed in some tasks from Chaos Beast subjugation, cleaning to servicing Momonga. In the end the two are told by Momonga the title of eldest did not matter as it was not a detail that worried their creators that much as in his opinion they wanted them to get along and not fight. CZ hearing that decided to cease their competition and make peace with Entoma, though it was temporary as the two maids got into a dispute over which chair they made for Momonga was better.[21]

The maid would be part of Sebas Tian's personal initiative to spread an atmosphere of hospitality to the overworked Floor Guardians. As part of her way to brighten Nazarick, CZ created a beautiful flower field on the 6th Floor for Aura and Mare.[22] CZ would be paired with Entoma to chaperone some soldiers that came from beyond the Crack. While interacting with them on a training mission out in the skies of the New World, CZ expressed her liking to the leader and placed one of her One-Yen Stickers on her back. The party is attacked though by by several flying type Chaos Beasts and a Giant Flying Chaos Beast which forced them to retreat.[23]

During a Nazarick event like the Nazarick Fighting Tournament, CZ was part of Cocytus's team "Cocytus and the Pleiades". Her team was victorious and came out as the winners of the tournament.[24] CZ would be called again by Momonga to scout a mysterious island that was connected to Nazarick via a temporary [Gate]. After receiving some water-proof gear such as the swimsuit. Together with the Pleaides she had to battle undead and a Giant Mollusk in order to claim the pirates' loot.[25] When the protagonist was doing a sting operation to capture the ones responsible for a string of disappearances in E-Rantel, CZ operated in the shadows to monitor the protagonist's and Blue Roses investigation. She helped capture a suspect by sniping him from afar, keeping out of sight until the protagonist's adventurer team were alone in the E-Rantel's Cemetery to wish them luck.[26]

Another event such as the Christmas party came to Nazarick, though CZ was unable to participate as she was stuck on guard duty on the 6th Floor with Entoma and Cocytus but could hear the complaints of her sisters from the cantina as they were cooking Christmas Cakes.[27]

At the time when most of the NPCs in Nazarick were being mentally influenced by a New Year's epidemic, CZ found herself compelled to head to Fake Nazarick where it was transformed into a strange Chaos Zone. There she was encountered by Momonga and his team who were investigating the cause. Unaware of the danger to CZ all was fine despite the eerie situation and concentrated kite flying.[28]

When Shiramochi-ō, the mastermind behind the New Year's effect over Nazarick, was defeated by Momonga and his allies that should have been the end of the spell over the Nazarick and the NPCs, however the entity used the last of its power to restart time, creating a loop of the same events that led to the New Year's epidemic with some slight changes. Once again CZ, was under the mental influence as in the previous timeline but rather than finding herself all alone in the middle of a Chaos Zone, she was with the Pleiades and Pandora's Actor waiting for Momonga and his team to play karuta. After Momonga and his team won, the party was given a treasure bag and mallet as prizes. The spell was broken after the character Shiro who was actually a regressed Shiramochi-ō willingly allowed himself to be killed by Momonga. Though the maid had no recollection of what happened.[29]

Other times like during the second summit of the Tripartite Alliance, CZ was stationed at the rooftops under invisibility magic to monitor the area near the venue of the conference. From her view point she informed her allies that the inner city guards were having a skirmish with a riot of the people. In the commotion, she sensed that her summons was crushed underfoot by the mob.

The conference was disturbed by a greater threat of a horde of Chaos Beasts approaching the city. When the protagonist volunteered to head out to deal with the monsters before they reached the city, Entoma and CZ secretly met with him and his team at the north gate to support him. They cut through the waves of Contaminated Beasts and Chaos Beasts until they came across a Double Sword Chaos Beast. The beast was regarded as a severe threat and eliminated thanks to the combined might of the covert agents and undercover adventurers. Once it was killed credit was given to the protagonist to bolster his image.[30]

CZ would act on guard detail for some new visitors from the Crack along with Yuri Alpha in the Tob Forests making sure that their guests were protected while interacting with one of their mad comrades.[31] At the time of second cherry blossoming viewing, CZ made preparations of the arrival of the Parent Tree to the tomb.[32]

More stranger occurrences happened like when Albedo temporarily became a maid, and helped settled a dispute with Entoma and CZ, the latter who was angry at the Arachnoid for eating one of Kyouhukou's subjects while they were cleaning the Lemegeton. The two would participate in a raiding drill on the 9th Floor in the event of an attack. During the drill the maids had to prevent the intruder, being Shalltear, from reaching Momonga.[33]

CZ was sent out into the field with the Pleiades, acting as part of the monitoring team, shadowing the protagonist's mission to a seaside village to learn about a dwarf named Tsuibayaya who may have some connections with players. There the plan was complicated by the appearance of Blue Roses who were looking for the dwarf to acquire some armors he promised to the royal family. CZ and the rest of the other Pleaides, with the exception of Solution and Narberal, kept to the shadows to avoid detection from the adamantite adventurers. It turned out that the dwarf was just a craftsmen who replicated items like swimsuits based on stories he heard. The dwarf wanted to create the perfect swimsuit but to do so he believed that he needed the scales of the Legendary Mermaid. As he refused to help the adventurers, he made a deal to have them retrieve the scales in exchange for his armors and services. After the adventurers agreed, the adventurers split to cover more ground. At that point CZ and the rest of her sisters came out of hiding to assist the protagonist. Now equipped in her swimsuit, CZ helped locate the Tide Pool and attempted to dive in there with Yuri only to have her floatation device bring her back to the surface. After confirming it connected an underwater network of tunnels, she and the Pleiades retreated to avoid being seen by Blue Roses. When the Legendary Mermaid challenged the gathered adventurers to a duel, CZ was the one who secretly helped them achieve victory by sniping the demi-human from a distance. Once the scales were acquired and given to Tsuibayaya, who finished making the Sage's Swimsuit and gifted it to Gagaran. Upon it completion and achieving his dream, the dwarf presented Blue Roses with the armors. However after they left the craftsmen was at a loss of what to do as he accomplished his life long dream. Taking pity on the dwarf, the protagonist had the Pleiades dress in their swimsuits to show the craftsmen the true swimsuits he was attempting to craft making him motivated to craft even better versions.[34]

A haunting of the Tob Forest began to occur, and blame was put on evil spirits that were angry for being neglected due to the absence of the Harvest Festival. With Carne Village abandoned, Nazarick felt that the only way to resolve this was to complete the event to appease the spirit. CZ helped the Pleiades, Aura, Hamsuke and the Death Knight set up the event. The event was adapted to a Bon Odori and the maids wore yukatas to commemorate it. However during the festivities at the village, they were attacked by a giant fox. In the confrontation, Shizu was enthralled over the "cuteness" of the beast. It turned out the giant fox was just a creature named Kyuko who spent a centuries long journey searching for beings similar to her. She had come to the Tob Forest hearing about the Wise King of the Forest and believed Hamsuke was a being similar to her. The hauntings were just her using invisibility while spying on Hamsuke and Nazarick's minions, the latter Kyuko assumed to be Hamsuke enslavers hence why she attacked. Once the misunderstandings were cleared up Kyuko was offered a place in Nazarick which she accepted and enjoyed the remaining hours of the festival. To show her liking to the new recruit, CZ put a One-Yen Sticker on the fox's back.[35]

CZ was present in the cantina when a new batch of visitors from the Crack came to Nazarick, led by a paranoid hero character.[36] When another group of new visitors from another world came to warn them about the Waves of Calamity, CZ was part of their entourage, guiding them to the Tob Forest to have them assist in the Chaos Beast subjugation. The visitors to Nazarick would be attacked by another group that came out of the Crack who were under the belief killing them would prevent the Waves of Calamity. CZ and the rest of the entourage were ordered not to interfere until both parties intentions were made clear and if they were threats to Nazarick. Once it was made apparent that the new group were clearly unreasonable and the aggressors to the conflict, Momonga ordered the security to engage them and protect the former group. The Nazarick agents made short work of the aggressors and prepare to eliminate them however the visitors of both parties seemingly vanished.[37]

At the time of the Demon Emperor Jaldabaoth's attack on E-Rantel, CZ posed as a Demon Maid and slaughtered the city guards that resisted the demons pillaging the city. The maid attacked Brain and Climb from the rooftops using her firearm. When they were about to pursue her, she came to them instead and attacked.[38]

Due to her knowledge on all the gimmicks in Nazarick, CZ was assigned to determine if there were any traps set by Luci★Fer and she found one, the Open Air Golem that only activated unless a harem appeared in its presence. The maid was one of the contestants of the Miyoshi Cup to get nominated to be the one to challenge Miyoshi for his title as bathing attendant of Momonga. However CZ lost in the politeness challenge as she refused to clean Neuronist Painkill which was the contest. Afterwards to deal with the golem, she helped to deactivate in when Momonga and several female NPCs were in its proximity.[39]

After Nazarick received a priority [Message] from Cocytus that the Great Lake area was being frozen by a abnormal cold wave and threatening to freeze the lizardmen and driving the native monsters from the northern monsters, CZ alongside Entoma and Lupusregina were sent to determine the cause of the weather change. Before they left they were given Christmas Costumes to protect them from the frigid temperatures. They made their way towards the northern mountains following the source, on occasion fighting beasts that were trying to escape for the cold. The maids finally came to a cave where the found a Crack and the Frozen Giant that was continuously bashing anything that emerged from the phenomena, its strength creating the wind pressure that was creating the cold front. The monster proves to be very formidable but Entoma was able to deduce a weakness in its structure allowing the maids to set fire on it and cause to crumble. To draw its attention CZ used herself as bait long enough for Lupusregina to set fire on the vines holding the thing together. After their successful mission the group returned to Nazarick just in time for the second Christmas party.[40]

Some old visitors to Nazarick returned being harassed by an evil clone of one of their associates. In a plan to seduce the clone and seal her power, CZ participated in a plan to set up an Cat Café where she and Lupusregina used several cats to appeal to the clone and set the mood for the date.[41]

The Pleiades were called into session by Yuri to brainstorm some ideas on what kind of chocolate she should help Aura make for Project Valentine. In her feedback she made a note that the chocolate from Valentine's Day was of a different quality served at the cantina. She acted as one of the judges for the taste test of the confections for the project.[42]

In a meeting to discuss the implementation of an idol plan, it was suggested that CZ be used as their idol as she was very popular with the general maids. Though ultimately the idea was cast in favor of using Shalltear and Aura instead.[43] CZ would also be present at the second campaign for LittleMass, and cheered alongside the general maids and her sisters at Acidity and Alkaline performances.[44]

CZ would also participate in a performance test of Tsuibayaya's swimsuits against those in the Treasury. Like the others she concluded that the dwarf's creations were still inferior to those in Nazarick's possession. When the "Nazarick Swimsuit Athletic Meet" was organized, CZ chose to join Albedo's White Group. At the first competition called "Sandy Beach Obstacle Race" CZ came in second place at the finish line. White Group won thanks to the extra points Albedo earned for defeating the obstacle monsters. In the second competition, which was the "Floating Island Survival", the maid was the sixth to jump on the platform and maintain her balance in the center of the float. CZ was the first to predict that the float would not hold anymore people due to the weight of the people on it. The float would eventually break in half due to the weight of White Group. At the last competition of "Mix Gender Water Cavalry", CZ served as one of Albedo's supporters in the pool. Ultimately the game turned into a tie, though CZ and the participants celebrated the game as it proved to be a fun experience.[45] During the incident where Shalltear was found to be under the incomplete mental influence of a World Item, under the orders of Momonga CZ, Yuri and Pandora's Actor began transferring gold to the Throne Room to make preparations for the fallen Floor Guardian's revival. After the transfer of treasure was done the group were order to stand guard and monitor the Crack in the event of an incursion of the Chaos Beasts.[46]

At a Tsukimi organized by Momonga for the NPCs, CZ was at the moon-viewing party where she was disgusted to see Entoma and Lupusregina sloppily eating dango. The automaton maid asked them not to spray their food out while they were eating.[47]

Later at the approaching Halloween Festival, CZ and Lupusregina took time to cheer Foire up as she was still troubled by her experience with being controlled by a Pumpkin Monster during the last Halloween event. After Foire decided to put her effort to making sweets for the festival CZ encouraged her to do her best. For the festival, CZ dressed as her worker identity Shizu. As part of the festival CZ paired with Sebas Tian and Yuri for the defense training part of the festivities and helped guide the non-combatants on the 9th Floor to the panic room. They came across several Eight-Edge Assassins disguised as Chaos Beasts, prompting her and the others to engage them in a mock battle.[48]

CZ would be one of the maids acting as escorts to a trio of magical girls that arrived in Nazraick via the Crack. Due to her robotic demeanor it was mistaken by the girls for coldness but soon found that CZ was a warm-hearted person. CZ took a liking for the leader of the trio and gave her a One-Yen Sticker. Later she and her sisters would assist them in returning home by nullifiying the Chaos Beasts around the Crack in the Tob Forest.[49]

CZ was reported to be still collecting information in the Empire with Lupusregina around the time when E-Rantel was experiencing a minor epidemic. The E-Rantel Magic Research Institute requested more Contaminated Beasts to experiment on. Nazarick was unable to dispatch CZ or Lupusregina to the mountains as Momonga did not wish to recall them just yet. She and Lupusregina did return back to Nazarick to attend a commemorative Christmas party to celebrate the protagonist’s success in curing the disease afflicting E-Rantel, however CZ got into a childish fight with Lupusregina when she sarcastically stated she would save some treats for an absent Narberal.[50]

At the orders of Momonga to prepare for a possible "New Year" event that would affect Nazarick, CZ with her sisters did a "general cleaning" of Spa Resort Nazarick. Together with Sebas Tian they found no traces of anything. To makes sure they did not trigger any of Luci★Fer's traps, CZ elaborated on the potential situations to avoid while in the baths.

Later when Momonga decided to forgo some caution against celebrating the "New Year" and host a Kakushigei Tournament, CZ and the Pleiades were assigned to act as escorts with Sebas Tian and Pandora's Actor to protect the general maids in the spectator seats. Once again donning her kimono, CZ enjoyed the opening ceremony and matches between the Floor Guardians. Once the tournament ended however, CZ and the rest present in the Amphitheater found themselves transported in an odd Chaos Zone. Whilst Momonga and his party went to investigate the Bishamonten Shrine, CZ stayed behind with the others to ensure the safety of the general maids. Once Momonga and his party defeated the one responsible for the translocation, CZ and the others were returned to the Amphitheater. She and the rest of Nazarick were introduced to Shiro, the current Ruler of New Year, and now an ally to Momonga. To celebrate this new friendship, the maid joined in the festivities in watching Shiro play spinning tops with Aura and Mare.[51]

At the announcement of the Sorcerer Kingdom’s National Foundation Day Ceremony, CZ and the Pleiades were charged by Sebas Tian to serve as security for the venue. CZ expressed happiness as among the guests that were coming to the venue were Hamsuke and Kyuko. However Narberal advised the girl that she needed to restrain herself as the pair would be guests attending the celebration. [52] On the date of the National Foundation Day Ceremony, CZ greeted the lizardmen delegation arriving at Fake Nazarick. Afterwards she and the Pleiades, minus Narberal and Solution, guided them to meet the other guests which included Hamuske, Kyuko and a Death Knight, at a separate chamber where both groups became reacquainted with each other. They were then escorted to the replica of the Throne Room for the ceremony. Along the way CZ and Entoma arranged for demonstrations of the security of systems of Fake Nazarick. At the banquet portion, CZ was intently focused on Kyuko and Hamsuke making them uncomfortable. The maid would later witness the unveiling of the Sorcerer King Momonga Statue which left her in awe.[53]

CZ and her sisters were called again to participate in the live shows of LittleMass’s successor LittleMasStar. In the first live show, she and the Pleiades conducted a mock battle with the idols and later enjoyed watching the entirety of the idol campaign.[54]

When the same guest from another world returned to Nazarick for a third time, with some new faces, CZ along with Narberal and Solution acted as their escorts on the 9th Floor. However there was an incident when their guest began acting, causing Solution to direct him to his room. CZ and Narberal stayed with his female companions. It wasn't long until the maids and guest saw Albedo, Solution and Shalltear fighting with their old acquaintance, causing CZ to arm herself thinking that the guest was now an enemy. It turned out that the guest was suffering so a mental condition due to his power. Before she and the others could restrain him, he escaped by transforming everyone into copies of himself causing much confusion on the 9th Floor for Shalltear and Albedo who were the only ones unaffected. Once the ability wore off, CZ and the Pleiades laid in wait outside of Nazarick to follow and track the fugitive down after Yuri and Lupusregina 'failed' to capture him. Later as part of his condition to peacefully return and to stabilize his power, the guest was permitted to go on a few dates with the some members of the Pleiades. CZ observed with the remaining females guests along with Entoma.[55]

For the delegation to the Dwarf Kingdom, CZ and Yuri were selected to act as escorts. In the Tob Forest she met with the protagonist and Slimeko, where the former divulged in the real purpose of diplomatic mission, which was to locate the older races living in the mountains to learn more about the Incident. Before they headed to the Azerlisia Mountains, the party checked on Hamsuke on the status of the Crack in the forest and then with Aura where she finished making Fake Nazarick in a perfect replica of the original. Once it was deemed that there were no one tracking them, the four headed to the Great Lake to fetch their guide, Zenberu Gugu. While the lizardman agreed to guide them to the city of the dwarves that he visited in the past, he requested to match with Yuri. The demi-humans was outmatched by the maid's strength and was beaten. The group then met back in the forest and were joined by Mare and Cocytus who acted as their additional escorts.

Using Zenberu's limited recollections of his first trip, they managed to locate the general area of where the entrance to the underground city was but were unable to locate the chasm even with CZ's eyesight. Serendipity happened as Slimeko fell into the a patch of snow that covered the entrance. The party expected to see the city of dwarves, but were shocked to find the city abandoned for some time. CZ using her vision found two sets of tracks of two different creatures that went into the mines. The party followed her and saw that they belonged to a demi-human species and Giant Lizards. The latter were busy eating a corpse of a demi-human, so CZ and Yuri went forward to slay the beasts. Mare though detected a living presence that was invisible who turned out to be a dwarf named Bigosa who happened to be the father of Tsuibayaya. From him the delegation learned of the dire situation in the mountains and how the dwarves were driven to Feo Jera from Feo Raizo by the Contaminated Beasts. They managed to convince the dwarf to guide them to Feo Jera despite the danger.

But when they reached the city, on their mounts they were too late as the monsters had already breached the city and destroyed it. Though Bigosa was distraught over the fate of his people, but since the bodies they found were far less and belonged to only soldiers it hinted that his people may have evacuated. Bigosa was unable to know where else his people could have gone, but from a surviving soldier they were directed to Feo Berkana where the Regency Council hoped to gain the protection of the Frost Dragons.

With no time to waste, Mare used his magic to carve a path directly to Foe Berkana. What awaited them there was a horde of Giant Lizards preparing to attack the ruined city. Mare stayed behind to allow the others to speak with the ruling Frost Dragon and negotiate with it on behalf of the Dwarf Kingdom. The dragon was about to dismiss the dwarves from its palace as it refused to get involved or provide them sanctuary due to its belief that the end was approaching and everything was pointless to stop it. When it called Cocytus weak, CZ witness the Floor Guardian give it a punch that defeated it. From her point of view the dragon was not very strong and called it weak. After being pummeled and hearing how Mare killed all the Giant Lizards, the dragon reconsidered its opinion of refusing an alliance with the Sorcerer Kingdom. In the end it agreed to forge an alliance and also protect the dwarves on the Sorcerer Kingdom's behalf.

CZ and Yuri were the only escorts that stayed with Slimeko and the protagonist as they returned to E-Rantel. Just as they approached the city, the four caught sight of an army outside the boundaries facing against defenders from the Re-Estize Kingdom. Seeing trouble was brewing they decide to hurry closer to determine the situation.[56] From their position CZ reported that King Ramposa III and Crown Prince Barbro Andrean Ield Ryle Vaiself that were leading both armies had just vanished, followed by several soldiers in the armies. She and her companions could not discern what was attacking them as it appeared to be invisible. The maid followed the protagonist in heading to the city where they found it to be in chaos due to Chaos Beasts that had appeared via the many Cracks that opened in the area. Worse all magical communication was blocked in the city leaving them without support from Nazarick. CZ and Yuri escorted the protagonist and Slimeko through the city to reach the E-Rantel Magic Research Institute to hopefully meet up with Soi stationed there. The group traveled through the city, fighting when they had to and even fleeing when an invisible entity appeared. The group met up with Jugem's Goblin Troop and afterwards separated to reach the E-Rantel's Cemetery. There at the institute, she and her friends were horrified to find the place in ruins and all the researchers dead. Thankfully they found Soi, Fluder and Nfirea still alive on the lower levels. Before they could approach Soi warned then of the Spear Chaos Beast that was still there. CZ and Yuri were forced to fight the creature, but found that the monster was able to vanish and reappear, making it difficult to attack. Once it was determined that the Chaos Beast was not using invisibility but teleportation, CZ and Yuri were able to somewhat launch a counterattack, but stepped out of the way to allow Soi to deal with it so that they could rest. But even she was not match for it, forcing Nfirea to release a recently cured Gazef Stronoff from his cell. CZ and her sisters watched in awe as the Warrior Captain not only fought on par with the Chaos Beast but displayed superior abilities that that were beyond a human's capability. Soon Brain Unglaus and Climb arrived to deliver Razor Edge to Gazef so he could slay the monster, only for a Crack to form directly in the room.[57]

END of NON-CANON content


  • In the Web Novel, CZ2128 Delta was created by Tabula Smaragdina.
  • Her favorite food is a drink with extremely high calories. It tastes like strawberries, chocolate, and banana. Interestingly, she shared a chocolate drink with Neia Baraja.
  • She is referred to as just CZ by Yuri Alpha in the second Drama CD. Narberal also calls her by CZ in the trailer of the second Drama CD. Thus, it is likely that her other sisters will also call her CZ as well.
  • It can be presumed that CZ2128 Delta was not created by Garnet until or after YGGDRASIL was updated with "Valkyrie's Downfall" patch.
  • She's the first NPC who formally makes a friend of an inhabitant of the New World.
  • The first two letters of her name CZ are likely in reference to a firearms manufacturer, also referencing the fact her weapons happen to be a firearm.
  • In Mass For The Dead at the End of her Chaos Memory, she is gifted with a Spear Needle Pup by Lord Momonga.


  • (To Aura and Yuri): "...Ainz-sama is the nicest of all the Supreme Beings because he stayed behind."
  • (To Yuri about Neuronist Painkill): "...Neuronist is androgynous and thus has no gender, but why does it call itself 'onee-chan'?"
  • (To Neia): "...Chocolate-flavored. Calories are a little high... around 2000, But don’t worry. Eating good food and getting fat is a long-cherished ambition for women, according to a certain great person."
  • (To Neia about Ultimate Shooting Star Super): "He lent you an excellent runecrafted weapon. You should spread the word of Ainz-sama's greatness."
  • (To Neia): "It is a shame, but also true. Well, I know you must be shocked. I understand very well. Still, that is where you stand now. However, if you work for Ainz-sama, someday you will be able to call him Ainz-sama too. Devote yourself to it."
  • (To Neia): "...Neia. It is a predecessor's duty to teach those who come after them."
  • (To Neia): "...Don't mention it. One must show kindness to those who know of Ainz-sama's greatness."
  • (To Neia): "This I swear in the name of the Supreme One, Ainz Ooal Gown-sama... However, if Neia dies and is resurrected, that still counts as keeping my word, right?"
  • (To Neia): "...If you knew how strong the henchman demon was, you and the others might have been afraid and not carried out the operation. But for the sake of Ainz-sama's victory... we must win this battle. That was why I lied."
  • (To Neia): "...Good girl. If you were cuter, I'd put a sticker on you. Maybe a furry sticker."
  • (To Neia): "...Neia. I like you. Now that I've gotten used to it, your face is quite cute."
