She is counted as the fifth or sixth sister of the Pleiades, depending on the source.

Outwardly, she is a quiet, expressionless mechanical girl, but inside she is one of Nazarick’s kindest residents.

CZ2128 Delta is built around the concept of an “emotionless mech girl” who uses firearms.

Her serial-number-like name, gun-focused classes, and automaton race all reinforce this theme.

Her emerald eyes often give a damp, piercing stare that has been described as a “glacial gaze.”

She almost never changes her facial expression, making it very hard for others to read her feelings.

She speaks little and only when necessary.

Even when she talks, her voice is flat, sparse, and dotted with long pauses: ellipses turned into speech.

She is not used to polite speech, so when talking to superiors like Ainz Ooal Gown she will clumsily tack on formal endings, as if she suddenly remembers she should be polite.

This makes her sound like she is manually “patching” her speech rather than naturally using honorifics.

Despite looking cold, she is a genuine good person by Nazarick standards, with almost no malice in her heart.

She does not proactively save people like Sebas Tian or Yuri Alpha, but like Cocytus she can get along well with humans who approach her in a friendly way.

Her eldest “sister” Yuri Alpha has called her “the only younger sister with a sane personality” (paraphrased), which is high praise in a place like Nazarick.

Her goodness is quiet: she is not a hero, but she also has no personal drive toward cruelty.

CZ2128 Delta loves cute, small, and fluffy things.

She often visits the Sixth Floor to touch and play with Aura Bella Fiora’s magical beasts and with Hamsuke.

She also frequently carries Eclair Ecleir Eicler around under her arm like a stuffed toy.

In the mini anime “Pure Pure Pleiades,” she dotes on Pandora’s Actor when he disguises himself as a cat.

One of her quirkiest habits is her “one-yen sticker.”

When she takes a liking to a person or object, she marks it by sticking a tiny “1-yen” sticker on it—she even did this to the cat-disguised Pandora’s Actor.

Thanks to this combination of deadpan demeanor, subtle kindness, and childlike fondness for cute things, she is treated as a mascot by the regular maids.

When she enters the dining hall, the maids greet her with cheers and affection, often calling her with a diminutive “-chan”-like tone (in local equivalent).

Her relationship with Entoma Vasilissa Zeta is strained.

Because the two were designed as “twins” and their creator never clearly decided who is the elder sister, they often argue that they themselves are the proper “older” one.

CZ2128 Delta is one of six battle-capable maids of the Pleiades team.

She serves on Nazarick’s Ninth Floor as a combat maid, defending the tomb and carrying out special missions for Ainz Ooal Gown.

Her creator, Garnet, was responsible for designing many of Nazarick’s mechanical gimmicks.

According to her original setting, CZ2128 Delta possessed complete knowledge of all Nazarick’s traps and mechanisms, as well as how to disable them.

This made her extremely dangerous if she were ever captured outside Nazarick, since she would be a walking manual of every defense.

To prevent any risk of information leakage, Ainz Ooal Gown personally used memory-altering magic on her, replacing that sensitive knowledge with other, safer information.

Because of her automaton body, she has complete immunity to poison.

This trait is both racial (as an automaton) and highly useful in the many deadly environments and battles around Nazarick.

Within Nazarick’s social structure, she is well-liked and considered approachable in her own quiet way.

Among the Pleiades, she stands out as the “good-hearted, non-sadistic” sister.

Her epithet “Assault Raid Maid” reflects her focus on sudden ranged attacks and rapid deployment.

She is built as a rear-guard combatant who supports the team with precise gunfire.

Combat Style

CZ2128 Delta is arguably Nazarick’s only true gun specialist.

In the original game “Yggdrasil,” her race and classes were part of a late-game, large-scale event that added modern-style firearm users.

Because Ainz Ooal Gown’s guild members were mostly long-time veterans who had already settled on their builds before that event, almost no other guild NPCs ended up using this “new” class set.

This makes CZ2128 Delta mechanically unique within Nazarick.

She uses various magical firearms, from full-auto to semi-auto weapons.

She is capable of close to mid-range mobile shooting, as well as long-range sniping and fire support.

Her overall design is that of a backline damage dealer and disruptor.

However, she is not helpless at close quarters: she can use knives in melee to a competent degree.

Among the Pleiades, her physical attack stats are the highest, surpassing even Yuri Alpha.

This suggests that while she is a ranged specialist, she is physically formidable by maid standards.

Notable Skills

Magic Interference (provisional name):

In a mock battle against a doppelganger enemy, she used a shooting-based skill that interfered with spellcasting.

Under normal circumstances, the level difference would make it almost impossible for her to disrupt someone like Ainz Ooal Gown, but with support buffs from Aureole Omega during the mock battle, the interference succeeded.

Her full skill list has not been fully revealed.

What is known paints her as a specialist in ranged debuffs, precision fire, and anti-caster harassment.

Silver Magic Rifle

CZ2128 Delta’s primary weapon is a silver-colored magical assault rifle.

It uses the wielder’s mana to fire bullets, but still consumes discrete ammunition that must be reloaded like a normal gun.

The weapon can be fired in silence, as if it has a built-in suppressor.

However, it cannot perform curved or indirect shots; its trajectory is strictly direct-fire.

She is proficient in switching between burst, full-auto, and single-shot modes, adapting her fire to range and target.

This gun is central to her identity as Nazarick’s foremost gunner.

Scarf

She wears a legendary-class (Legendary tier) scarf.

This item grants her the ability to become invisible and also to become undetectable (for a short duration) to various detection methods.

The scarf enhances her role as a stalker-sniper.

It lets her reposition, ambush, or escape while remaining unseen or unperceived for critical windows.

Creator: Garnet

CZ2128 Delta’s creator, Garnet, is responsible for her gimmicks and for many of Nazarick’s mechanical devices.

She respectfully calls Garnet “Doctor,” reinforcing her theme as a constructed automaton.

There is mention in later material of “those other Shizus” seemingly also created by Garnet.

These other CZ-type units are hinted to possibly “activate when the time comes,” implying there may be multiple related automatons waiting for future use.

Pleiades Sisters

Within the Pleiades Combat Maids, CZ2128 Delta is considered the fifth or sixth sister depending on the counting method.

She is highly regarded by Yuri Alpha, who considers her temperament the most “normal” among their sisters.

She has frequent conflicts with Entoma Vasilissa Zeta over which of them is truly the older twin.

These arguments are a recurring gag and show that even this “emotionless” girl has a petty, almost sibling-like side.

Other Nazarick Residents

The regular maids adore her and treat her like a mascot.

When she appears in common areas like the dining hall, they react with delight and affection.

She enjoys visiting the Sixth Floor to play with Aura Bella Fiora’s magical beasts and with Hamsuke, indulging her love of fluffy creatures.

She also often carries Eclair Ecleir Eicler around like a plush toy, much to his dismay.

In side content, she is shown doting on Pandora’s Actor when he transforms into a cat.

This again triggers her “cute radar” and leads to her applying her trademark one-yen sticker.

Ainz Ooal Gown

Ainz Ooal Gown views her as a valuable and potentially dangerous asset.

He personally intervened to alter her memories, removing her knowledge of Nazarick’s complete trap and lock designs to secure the tomb.

When speaking to Ainz, CZ2128 Delta’s awkward attempts at politeness are noticeable.

She clearly recognizes his authority but struggles to express it smoothly due to her mechanical, laconic speech patterns.

One of CZ2128 Delta’s most charming quirks is her fondness for placing a one-yen sticker on things she likes.

This sticker acts as a personal “favorite” mark, signifying beings or objects she has quietly approved of.

According to the author, anyone who arrives in Nazarick already bearing one of CZ2128 Delta’s one-yen stickers would be greeted with immense enthusiasm by Nazarick’s residents.

Given that these residents are often seen as demonic or death-god-like figures by locals, this sort of hospitality is extraordinarily rare.

Receiving a one-yen sticker from her is thus described as a massive survival flag.

If she has marked you, Nazarick will treat you as someone under her protection.

However, because she is “good but emotionally muted,” the chance of an outsider earning such a sticker is extremely low.

To qualify, someone would likely have to care for her sincerely and selflessly over a long period, or be intrinsically fluffy and adorable enough to charm her without ulterior motives.

Ironically, any such person is unlikely to possess the strength or reason to end up in Nazarick in the first place.

This makes the one-yen sticker both a powerful, theoretical shield and a near-impossible achievement for any ordinary person.
