"It's wrong, it's wrong, it's wrong, it's wrong...my baby, my baby, my baby--! You, you, you, you, took, took, took, took, my baby, my baby, my baby, my baby--!"
- Nigredo's Introduction

Nigredo (ニグレド) is an NPC of the Great Tomb of Nazarick, she is the older sister of Albedo and Rubedo. Nigredo was imprisoned in the "Frozen Prison," situated on the 5th Floor of Nazarick and acted as an Area Guardian. She was released at the request of Yuri Alpha to help manage the new orphanage in E-Rantel.


Nigredo has an appearance similar to Albedo's, in the sense of hair, but the similarity ends there as her face has no skin, but rather, a mass of exposed muscle.

She has beautiful eyes and teeth, but there were no lips whatsoever, only beautiful pearly teeth. There are no eyelids, only brightly shining eyes. As such, her grotesque appearance horrified all the guild members of Ainz Ooal Gown, who all immediately attacked simultaneously upon seeing her.


Though she acts insane and attacks her visitors without mercy if a baby-doll isn't given to her, Nigredo is assumed to be tender-hearted under normal conditions. She and Pestonya opposed killing innocent people kidnapped from the Re-Estize Kingdom. In addition, Nigredo had a soft spot for babies, perhaps even surpassing that of Pestonya’s. However, her compassion is often limited to that of infants. Once they live past the age of two, she becomes mostly indifferent towards their well-being. Despite this, Nigredo does not actively seek harm towards humans unlike most of the denizens of Nazarick, and is a generally compassionate individual.


Nigredo was only the Area Guardian of the above-ground portion of the Frozen Prison.

Main article: The Witch of the Falling Kingdom Arc

When looking for candidates to run the intelligence agency that is being spearheaded by Demiurge, Albedo noted how her older sister Nigredo might be a decent choice. However, seeing that Nigredo was not an ally that Albedo could trust unconditionally, she starts to think otherwise about giving her the authority to manage it. According to Albedo, if Nigredo figures out her true intentions, she felt it was entirely possible for them to become enemies in the future.[6]

At some point before Ainz make his return back to Nazarick, Nigredo had requested her colleague Sebas to speak on her behest with their master which the butler obliged to do, considering she doesn't have permission to leave the area she was at. She and Pestonya wanted Sebas to have Ainz pay her a visit to the Frozen Prison alone where she was located in which their master agreed on doing after briefly discussing with the butler.

Once they are present, she began discussing with Ainz by offering a suggestion to her master that he should rent out more of his undead minions for agricultural purposes. She reasoned that by doing this, Nazarick would certainly have developments in the improvements of breeds of food. To back up her statement, she claims the food culture would surely blossom to the point that they can even produce food of an equal quality compared to Nazarick’s offering which Ainz approved of doing.

After the conversation shifted towards the main topic of discussion, she was the first before Pestonya to argue their cases to Ainz on why a large-scale massacre of the Re-Estize Kingdom needs to be avoided. Ainz however is adamant that the cull was deem necessary for the sake of strengthening the Sorcerer Kingdom and to make sure that human civilization could never grow too strong.

More so, he voice his concern of why Nigredo had not bother to contact her other superiors, the Floor Guardians instead of him. Seeing this, Nigredo who is an Area Guardian was viewed by Ainz to act detrimental towards Cocytus's authority as the Floor Guardian. According to Ainz, she was supposed to ask the Floor Guardian, Cocytus about this matter since she is part of his floor he manages under his rule. Although Nigredo offers her suggestions despite her position, none were convincing enough to make Ainz consider changing his decision about the massacre.

However, when Pestonya brought up the idea of letting humans escape alive as fearmongers through spreading the news of opposing the Sorcerer Kingdom to be hopeless, Ainz began considering it carefully. She along with Pestonya and Sebas were informed by their master that he will allow only 90% of the Re-Estize Kingdom's people to be wipe out while the rest will be allowed to live on. Once Ainz decides to take Pestonya's idea into consideration, she alongside the maid voice how eternally grateful they are to their master hearing them out.[7]

Ainz (Isekai Quartet) NOTICE: The following section and subsequent subsections are considered NON-CANON to the Overlord Light Novels.

Mass for the Dead Arc

Momonga solicited the aid of Nigredo in conducting counter surveillance of Shalltear's encounter with a human girl named Anne. After the encounter, and Shalltear's return to Nazarick, Momonga was informed by the magic caster that she detected no attempts at observing Shalltear. This relieved him somewhat as it meant that the likelihood that Anne was a player was low.[9]

Nigredo has been revealed to have been assigned by Momonga to monitor the site where Shalltear was brainwashed. Momonga, Albedo, Slimeko and the protagonist sought her in the Frozen Prison to ask her to help them in locating a mithril plate that belonged to Igvarge. After going through the horror ritual, Momonga gave her a mithril plate belonging to a member of Kralgra to aid her in her search. Using her magic she located not just Igvarge’s but also the other two plates that belonged to his dead teammates. Though one of the plates was on a Skeletal Dragon. Later when Darkness went to retrieve the plate, Nigredo and Albedo noticed New Six Arms movement towards the Katze Plains where Darkness was. Nigredo then informed the Nazarick agents who then planned an encounter with the workers in order to manipulate them into aiding them in taking down the undead dragon. Whilst enjoying being of service to Momonga, Nigredo also had the opportunity to spend time with Albedo and admire the Prime Minister dress Albedo received from their master. After the incident, Nigredo having learned of Albedo’s feelings for Momonga supported her younger sibling as she hoped they would produce a heir which she wanted to hold in her arms one day.[10]

Albedo suggested to Momonga that they should seek Nigredo’s aid once more to search for the missing lover of a new guest from another world beyond the Crack. Though it was not necessary after Albedo received a report from a summon in the field that located the missing woman.[11]

Nigredo’s help would be sought by the protagonist in order to stop a slave trading operation that was kidnapping and selling orphan children. With a description of a children that the homunculus wished to seek, Nigredo used her magic to pinpoint the child’s location. She expressed concern for the children as she saw that they were being treated poorly and many may not survive for long.

Her help was instrumental in providing floor plans of the slave brokers baseband warehouse. Not only that she helped located the necessary incriminating evidence to bring the noble responsible to justice. After the incident, Nigredo was informed by Pestonya of the news and that the proposal of the Sorcerer Kingdom Orphanage would soon be underway. The Head Maid provided Nigredo an opportunity to try out the maid uniform that the staff would wear. Nigredo was allowed to keep the outfit for awhile as she wanted to wear it while mourning the children who lost their lives, vowing not to fail the ones still alive at the orphanage.[12]

With the approach of New Year's Eve, and the coming of the White Mochi King, Albedo ordered Nigredo to monitor Shiro via her abilities for any abnormal changes.[13]

END of NON-CANON content

Abilities and Powers

Nigredo is a Magic Caster whose power focuses mainly on information gathering. She is known as one of the few NPCs of Nazarick whose power is close to the highest level, so it can be assumed that her level is over 90. Nigredo is shown to possess highly efficient and high level surveillance, anti-surveillance, intelligence gathering and scrying type magic.

As seen where she managed to easily locate Shalltear Bloodfallen after the latter's brainwashing and subsequent uprising against Nazarick. She was even capable of casting high level surveillance on the entirety of Nazarick's forces during Operation Gehenna. While so, she could skillfully cast anti-surveillance magic on the Royal Capital's safe houses and meeting spots in order to avoid detection or ward of anyone spying from any outside forces during their operations. Its been stated by Ainz, that Nigredo is a specialized NPC created specifically for this exclusive purpose.

For more offensive capabilities, Nigredo has been shown to be primarily equipped with scissors as her main weapons. In the Anime the it was showcased to be a large pair the size of a sword. While in the Light Novel Nigredo wielded regular sized ones, with her using them like daggers.


  • Remote Jamming: Inflicts magic damage to a single enemy, lowers attack power and defense power, and has a certain probability of inflicting a sealed curse state.
  • Fictional Projection: Decrease the hit rate and evasion rate of all enemies and increase the evasion rate of all allies.
  • Abyss of Madness: Inflicts magic damage with "darkness" element to all enemies and reduces all stats and hit rate.


  • Chop: Deals magic damage with "darkness" elements to all enemies and cancels all advantageous effects.
  • Clairvoyance: Increases the hit rate.
  • Detection Measures: Increases evasion rate and charges a certain amount of arts gauge at the start of battle.


Ainz Ooal Gown

Nigredo is loyal to Ainz and uses her surveillance skills to aid him in searching for Shalltear. Ainz decided not to kill the remaining humans kidnapped from the Re-Estize Kingdom, because Nigredo alongside Pestonya risked going against his orders to save them.

However despite her blatant disregard to his orders in order to save innocent humans, Ainz never once felt any hostility or grudge against Nigredo due to deeming that this was only how his friend Tabula had made her out to be and avoided executing her despite the majority of opinions of the other NPC's on how to deal with the matter.

Later during the events of the Fall of the Re-Estize Kingdom, its shown during Nigredo, Pestonya and Sebas's pleadings for mercy for the humans of the Re-Estize Kingdom's innocent civilians to be spared, Ainz still did not harbor any sense of offense in her disregard for the common structural procedure in contacting him and her apparent objection to his direct orders and Ainz later took serious consideration in Nigredo's request to spare some of the populace of the Kingdom before eventually promising to somehow follow through with their request if possible. Eventually Ainz successfully followed through in his promise by sparing the people of E-Naeurl and later having a majority of the children and some of the citizens of the capital of Re-Estize evacuated before the final siege. Further deepening Nigredo's loyalty to him due to his apparent kindness and benevolence in accepting her request.

Tabula Smaragdina

Tabula is Nigredo's creator. To him, she was the strong manifestation of his other passion: horror films.

During her first appearance and interaction with her younger sister Albedo, Nigredo was shown to greatly look up to and respect Tabula Smaragdina and refer to him in honorifics. As such it can be guessed that similarly to the other NPCs, Nigredo respects Tabula the most out of the forty-one supreme beings of Nazarick and holds her loyalty to him first and foremost.


Albedo is Nigredo's younger sister. Nigredo is shown to genuinely love her younger sister Albedo and fondly refers to her as her "Lovely Little Sister" and Albedo in turn refers to Nigredo as "Nee-San" in a respectful/fond manner, showing her sense of respect and love for Nigredo as her elder sister. Unlike her opinion with her other little sister, Nigredo is shown to have a genuine loving relationship with Albedo and trusts and respects her both as Guardian Overseer and as a fellow creation of Tabula Smaragdina. However, the only real source of schism between the two is Nigredo own's paranoia and immense dislike for their youngest sister Rubedo. As seen where Nigredo warned Albedo that Rubedo might bring a calamity to Nazarick and expresses her paranoia and active dislike for her, but Albedo only replied that she thinks Rubedo is an adorable younger sister and that she would never be a scourge. Nonetheless, Albedo still listened to Nigredo's worries and still put her opinion under her consideration out of her duty as Overseer and her trust in her elder sister.

Later during Albedo's inner thoughts about the development of the Sorcerer Kingdom and the future of her Secret Unit and the possible danger the new Intelligence Agency being created could breach her plans if Demiurge was placed as its leader. Albedo briefly considered recommending her elder sister as its head to further her plans, but quickly shot down the idea upon feeling that she could not fully trust her unconditionally in her future plans. Nigredo was openly consider by Albedo about the probability of the two becoming enemies if her plans about the secret unit is revealed to her. This goes to show that Albedo now harbors open mistrust and paranoia for her elder sister should she become suspicious of her true intentions.


Although she is also her younger sister, Nigredo views Rubedo as a potential threat to Nazarick as she was not made the same way.

Pestonya Shortcake Wanko

Unlike the rest of the denizens of Nazarick, Nigredo and Pestonya opposed killing innocent people kidnapped from the Re-Estize Kingdom by Demiurge. They both went out of their way to free them though at the risk of punishment as a result of it.

Eventually, due to their shared time together and similar mind-sets, Ainz assigned them both the duty of overseeing the Sorcerer Kingdom Orphanage to look after the orphaned children of E-Rantel and as such Pestonya and Nigredo have now become much closer due to their new shared assignment.

Sebas Tian

As Sebas is a fellow human sympathizer, Nigredo possess a level of affinity with him due to their shared sense of mercy and kindness towards humans. As seen where Sebas accompanied and approved of Nigredo and Pestonya's pleading with Ainz in order to spare some of the innocent civilians within the Re-Estize Kingdom. He was known to support and approve both of their opinions and alternate options to spare some of the humans in order to further Nazarick's agenda and welfare without mass slaughter during the events of the Fall of the Re-Estize Kingdom.

Shihoutu Tokitu

Nigredo is noted to have a strong friendship with Shihoutu Tokitu, Nazarick’s chief. During her and Pestonya disobdience in helping and sparing the children abducted in the Demonic Disturbance, Shihoutu secretly assisted them by giving them baby food to feed the infants.

Later , Shihoutu would invite both Nigredo and Pestonya to a lavish dinner meal with his other close friends in Nazarick.


  • In the Web Novel, Nigredo doesn't exist, along with her sisters.
  • Nigredo is a Latin word meaning "Blackness."
  • Due to the anime adaptation skipping her involvement in the Bloody Valkyrie Arc, Nigredo did not make an appearance until the 9th episode of season 4.
    • Similarly, she also has not yet debuted in the manga.
  • Nigredo's physical description matches almost completely with the description of Frankenstein's Creature in Mary Shelley's original book.


  • (To Albedo about Spinel): "I extremely despise that girl, even if we are all the creations of Tabula Smaragdina-sama No, the way Spinel was created was different from the way we were. She is definitely not the type that others can open their hearts towards."
  • (To Albedo about Spinel): "The way I see it, you have been deceived by her. Spinel will definitely bring a great calamity to Nazarick, I guarantee it."
  • (To Albedo): "Is that so? If you the keeper of the Guardians have decided like this, then I won’t say anything more. However, I still hope that you, as keeper of the Guardians, will bear my concerns firmly in mind."
  • (To Ainz): "Yes. Given the current situation, isn’t it about time that we stop massacring the citizens of the Kingdom?"
  • (To Ainz): "All infants have potential, Ainz-sama."
  • (To Ainz): "I see, that is true. But, isn’t the same true for dragonlings too?"
  • (To Ainz): "What we had just talked about, improving the breeds of food, doesn't that apply to humans too? If we were to apply the different techniques we have in Nazarick to strengthen them, surely stronger varieties of humans could be made. Plus, a race's value isn’t just in their strength, humanity's propensity for creativity in their creations...you could call it the ability of cultural development, I believe they do have that ability. If we were to reduce their population to nothing, isn't that a great opportunity cost to Nazarick?"
