**Nyx**, also known as **Mother Night**, is the Greek Primordial Goddess of the Night and Magic and personification of the Night, who was held in great esteem among the ancients, so much that even Zeus himself stood in awe of her. Her counterpart is the Roman Goddess Nox.

She is the youngest daughter of Khaos and Caligo, and is the youngest sister of Chronos, Gaia, Ouranos, Ananke, Aion, Phanes, Tartarus, Eurynome, Ophion, Eros, Pontus, Physis, Erebus, and She is the aunt of Hydros, Thesis, Ourea and Nesoi.

She is one of the creators of Aether, Hemera, Thanatos, Hypnos, Oneiroi, Moros, Atropos, Lachesis, Clotho, Nemesis, Dolos, Apate, Geras, Philotes, Momus, Oizys, Charon, Alecto and many others with or without Erebus, and Achlys with her mother, Khaos herself.

Her appearances are sparse in surviving mythology, but reveal her as a figure of such exceptional power and beauty that she is feared by Zeus himself. Nox, though she is truly an avatar of the Roman goddess to deal with the Greek Empire.

Throughout her life, Nyx became the guardian of numerous gods, including Hades, Styx, Pandora, Hecate, Eris, Zagreus. She is the best friend and arh-rival of Malkuth. She's also the main arch-enemy of Amara and Nox's arch-nemesis.

She was a member of Spriggan that previously was apart of the the now defunct Alliance of Hell who betrayed the Greek Pantheon after Ahriman took over, and now is an ally of Team DxD.

Nyx is currently enrolled in Kuoh Academy as a Third-year student and is a member of Issei's class 3-B. Nyx is also apart of Issei's harem after he saved her from being imprisoned in the depths of Hell.

## Overview

**Nyx** is the primordial Greek goddess (and personification) of the night, her name means "the mother night." A shadowy figure, Nyx stood at or near the beginning of creation and mothered other personified deities such as Hypnos and Thanatos, with her brother Erebus, her mother Chaos and even Zeus himself once.

Nyx spends majority of her time sleeping. She get's woken up by powerful clashes that take place between Deity. Because God is the source of most, she despises her because she affects her ability to sleep. Nyx lives in a secret pit of darkness that no one knows about.

Nyx was finally found and was confronted by Zeus when Artemis had became a threat far too powerful for anyone to handle but the Primordials. Nyx has denied his request, and once again went back to sleep.

She is the Greek counterpart to the Roman deity Nox. Versions of her birth and origins vary, but one interpretation has her as a creator goddess, laying a silver egg that produces the gods responsible for the creation of the world.

## Appearance

In a Past, She is depicted as a goddess draped in long flowing black robes that are coated with the void of space and glimmering distant stars. Her appearances in mythology are sparse, but reveal her as a figure of exceptional power. In ancient art Nyx was depicted as a either a winged goddess or charioteer, sometimes crowned with an aureole of dark mists.

Nyx is a beautiful young woman with the cute face of a child that has long black hair and with pointy ears. She has dark blue eyes, an average height, a well-endowed figure and large breasts. She wears a cute frilly dress called the Godly Virgin Killer Clothes that has a corset jumper skirt.

Her body also gives out a tremendous dark aura. After Her notable accessories are twin butterfly-shaped ribbons which are on both sides of her head. She is noted to be the more fashionable girl among the childrens, as she has various cute accessories and takes care of her nails. Her ears have yet to be pierced, but she plans to have them at least before marriage

In her true form, Nyx was described as a churning figure of ash and smoke, as big as the (which was 40 feet tall). Her face was hard to see except for the pinpoints of her eyes, which shone like quasars. When her wings beat, waves of darkness rolled over the cliffs. Her dress was void black, mixed with the colors of a space nebula as if galaxies were being born in her bodice.

After transferring to Kuoh Academy, she wears the Kuoh Academy girls' uniform, albeit with a red ribbon vest over her corset jumper skirt in place of the cape and corset which has become her current main attire.

## Personality

Before the disappearance of Khaos, Nyx was like any other young goddess; cheerful and upbeat who loves her family, especially her older sister Eurynome despite not seeing each other so often. She is a cheerful, yet sadistic person who enjoys seeing her enemies in pain and suffering. She also hates being alone. Even during the War of Creation, Nyx was still the same person though she became far more ruthless in nature.

Despite the cold and rude front, Nyx is caring and protective, like when she is touched by Hyoudou Issei's past; remarking that it is also evident by her willingness to act as the her creations and wards, ignoring her care towards her own appearance.

However, she does have an honorable side to her as she greatly admires "true heroes" and those who gain their power and authority through noble means. She is not above praising others such as Rias being worthy of being Issei’s King because she figured that Nyx was waiting for Issei to attack her.

She is a very headstrong and straightforward person who tends to be quite blunt. She is strong willed and motivates herself to escape the ties of her past. Nyx's bonds lie within her classmates whom she normally takes the leadership role with. She's very tough on them in training, very impatient and often hot-tempered. She only wishes to see them get stronger as they fight beside her and has taught many of her peers how to properly wield a variety of weapons, even if they had to get beaten up by her a lot to reach that point.

With Issei, Nyx was initially annoyed with his pervert attitude and felt that she had no business being at Kuoh Academy as a Student. However, after fighting beside him and learning to understand one another, Nyx discovered they weren't so different. In fact, Issei was the first person to truly make her feel accepted. In this instance, Issei's tough exterior tried to repress her emotions with frustration but she couldn't help but feel moved in a very rare show of emotion.

When Khaos was sealed in the Nihilo Mask along with Azathoth, Nyx was one of the Primordials that pretended to serve God after the war but in truth was busy serving under Chronos to free her mother from the prison. Due to the hardship she had been put through from the loneliness. Nyx became far more mature and wiser, raising her children with Erebus while watching Gaia and Ouranos had their own children. Though she is proud of her children and is very protective over them, Nyx can be uncomfortable when someone asks her who is her favorite child.

Even after Khaos was freed, Nyx hid her cheerful and upbeat personality she had before under far more sadistic and brutal with a loyal respect to the Olympian Hades, shown she served him in the Alliance of Hell. Because of this mature personality, when Khaos disappeared from Creation, she didn't freak out like her brother and Erebus did though she did become worried with her mother's whereabouts.

Nyx gives her children many gifts and once she has given a fledgling or vampyre an affinity, she never takes it back. Those who are given such abilities often excel in society, becoming High Priestesses or Warriors. Nyx's greatest gift for her children is free will, as she often says herself. She enjoys the pleasures of it, but mainly does it for the sleepy feeling she gets.

Nyx speaks with a very powerful tone. Her voice is very overpowering to hear even to gods. Due to her lack of social interaction, she speaks different than most. She has a habit of dragging out her words. Nyx does not like evil beings as they are the ones that wake her up most of the time. As such she despises God more than most.

Nyx on rare occasions does not spend her time sleeping. Nyx is a very lazy goddess, often not wanting to help with anything even if she is fully awake. She is also the main inspiration behind the Moon Deity figure featured in numerous polytheistic religions throughout the world, serving as the template for their creation, with the most notable ones being Artemis, Selene, Thoth, Chandra, Tsukuyomi, etc.

As the Primordial Deity worshipped by the Second-Generation Primordial, she holds a softspot for them, both because of their devotion toward her, as well as the fact she was their creator. Unlike regular gods, who only bless their mortal devotees if their faith toward them and their offerings are great enough to satisfy them, she will try her best to take care of her worshippers, even though she had been greatly weakened due to her banishment from Heaven and God's hibernation.

According to Artemis, she acted more of a mother/grandmother doting on her grandchildren than a goddess interacting with her worshippers. Whenever she becomes angry, the world around her will become greatly twisted to fit her moods: the sky will become darkened, the sun and the moon and the stars will all disappear, devastating cases of natural disasters will randomly appear across the world, etc. According to Thanatos, she was one of the Protogenos who was involved in the destruction of Sodom and Gomorrah.

After receiving her special garment, Nyx became arrogant enough to believe she is untouchable by those who are virgins. Her rebellious attitude makes her the least cooperative girl among the friends, making her archetype resemble that of a "Tsundere". Her interests seem to lie more on romance than anything else. An example is when she wanted to watch a romance movie, whilst Rias preferred a science documentary instead. With this is mind, she likes to openly state her feelings for Issei, regardless of whether it's in front of him.

Of course, the most noticeable of Nyx's dispositional characteristics is her denial of her shortness. Even in moments of relative composure, any and all references to her stature cause her to violently lose control of his emotions and lash out both verbally and physically. One of the most common reasons for these outbursts is if anything related to her size, since she has a complex about being shorter than average (her height is 156 cm). Distinctive to these outbursts is Nyx's tendency to take even the most casual mention of her height as a gross insult and interpret it exaggeratedly, mistaking words as simple as "small" for phrases as contrived as and the like.

She likes to climb to high places. Nyx likes everything bears and rabbits-themed, and becomes quite sensitive when someone insults her obsession with them. People often have difficulty understanding her drawings, which are typically bears and rabbit-like, and doesn't like it when people complain about their quality. Nyx's favorite foods are Strawberry milks, Egg tarts, and Cheesecake.

## History

### Creation

Nyx was born directly from Khaos. She had originally lived with her mother along with the majority of the Primordial Entities, during the time before Creation. Due to Khaos being protective of her youngest, she kept Nyx and Erebus hidden from the Creation War.

After the war, when something akin to peace had been established, she lived in Tartarus, in the Mansion of Night, where she stays during the day and leaves during the night.

During the time when she lived with her mother, she had mated with her older brother Erebus, creating the primordial gods Aether and Hemera in that order. During the time of Ouranos' rule, Nyx, her daughter Hemera (whom she had fights with), her son Aether, and the stars were the only constant company of the deity. Nyx and Erebus mated once again, this time creating far more deities like Thanatos, Hypnos, Moros and many others.

### Meeting with Amenominakanushi

Nyx would at one point bump into Amenominakanushi. The two began a fight over a silly reason. Nyx emerged victorious though was by the fight, prompting her to go to sleep for two centuries.

### Family Feud

During the Titans' rule, Nyx and her daughter Hemera (who were currently living together in Tartarus along with Thanatos and Hypnos) had a big fight with them, not wishing to be near the other. This caused one to leave Tartarus, while the other was returning and vice versa, creating the night and day cycle. After some time, both of them calmed down and were able to get closer and when the goddess Eos came along, they were able to get mend their relationship. After that when Hemera arrived, Eos would leave, followed by Nyx.

### Persephone married Hades

At some point in the ancient past, she was gifted with the knowledge of creating the Reapers from the Archreapers, and was tasked with the duty of creating new generations of Reapers to harvest the souls of deceased mortals and take them back to the Realm of the Dead, with hers responsible for taking them to the Greco-Roman Underworld in particular.

She later taught it to Persephone after she married Hades and became Queen of the Underworld.

### Hypnos

When Nyx's son Hypnos reminded Hera of an old favor after she asks him to put Zeus to sleep. He had once before put Zeus to sleep at the bidding of Hera, allowing her to shower Hercules, who was returning by sea from Laomedon's Troy, great misfortune without Zeus interfering. When Zeus heard of Hypnos' involvement of that event, he became furious and chased him into the seas beyond even the control of Leviathan, the Primordial Beast of the Sea.

He would have smitten Hypnos into the sea if he had not quickly fled to Nyx in fear, who Zeus respected enough and feared even more to hold his anger at bay. In fact, the king of the gods was fearful to the point where he held his fury at bay and in this way Hypnos escaped the wrath of Zeus by appealing to his powerful mother. He disturbed Zeus only a few times after that always fearing Zeus and running back to his mother, Nyx, who would have confronted Zeus with a maternal fury.

## Equipment

**Godly Virgin Killer Clothes**: A special clothing given to her by the Gods in the Alliance of Hell which allows her to be immune to the attacks of virgins. That is, techniques such as "Dress Break" and "Pailingual" cannot work against the wearer. Clothes are capable of protecting even from such abilities using Infiltration. When touched by virgins, clothing imposes a fatal curse on them. However, it does not protect against the shock-wave of a canceled attack. Cao Cao suggested that Nyx might have been lying and that it was actually "clothing that protects against dragon attacks."

**House of Ideas**: The House of Ideas is the residence of Nyx. Within this area, endless stories will arise and thoughts and ideas can be physical shapes. The home has many beginnings on earth, as humanity is so important to Nyx's design and it was recently revealed in Hewlett Harbor, Los Angeles. It can create things according to her ideas and can change everything she actually wants.

**Night Chariot** (夜の戦車, *Yoru no Sensha*): The divine chariot of Nyx. It is an Roman chariot made out of sharp obsidian and gleaming metals, pulled by two Night Mares named "Apóchrosi" and "Skiá". Every night, as the sun begins to set, she will pick up her mantle of night over her shoulders and ride her chariot out of the Underworld into the mortal world, bringing the night to the mortal world.

**Nýchta**: A powerful divine blade that is wielded by Nyx. It is able to control darkness and use it as a weapon. It is the counterpart blade to Erebus' *Skotádi*. Nyx has, on more than one occasion, used Nýchta's wide blade as a shield from incoming attacks, and for deflecting energy attacks. Unlike most divine blades, which can be sealed into their original form, Nýchta is always in its blades form. Amatsu-Mikaboshi has stated her *divine blades* is a full-time released form type because of Nyx's vast but uncontrollable divine aura upon generation of it, implying it is simply a type of *divine blade* which, without proper control of her darkness, remains in blades form once in said state.

* **Celestial Shade**: Nyx imbues the sword in Amenominakanushi's power, creating a blade that can cut all spatial constructs. The blade can now not only preform feats such as cutting an entire galaxy cluster in half, but can also alter the positions of Nyx and her target, quite literally letting the former skip distances immediately.

* **Temporal Shade**: Nyx imbues the sword in Khaos' power, creating a blade that can cut all temporal constructs. The sword can nullify time-manipulating abilities of the highest and most powerful variation, quite literally giving Nyx the power to cut the concept of Time itself (meaning she can damage Amara and Azathoth).

**The Chains of Heaven and Hell**: Nyx's choice of weapon are crystallized mana chains called the Chains of Heaven and Hell. She uses them to skewer her opponents or to grab them and bring them closer to her. She can also use these chains to restrain her opponents. These chains can channel magic so if she has anything in the grasp of these chains, Nyx can kill them by sending fire or electricity.
