**Ingvild Leviathan** is one of the descendants of the original Leviathan and the Queen of Issei Hyoudou's peerage. She is the possessor of the Longinus; **Nereid Kyrie** and the current Satan Leviathan.

## Appearance

Ingvild is a beautiful foreign girl who appears to be in her late teens with a "whimsical aura." She has long purple hair and orange eyes.

She wears a white dress typical of female noble Devils that exposes much of her large breasts, with high slits and long sleeves. She also wears a black mini skirt.

After joining Issei’s peerage and becoming a student at Kuoh Academy, Ingvild now wears a female school uniform with long purple socks.

Her measurements are 168 cm (5 feet 6 inches) with a cup size of 103, which eventually grew to 106.

Her Satan Leviathan attire consists of her white dress with a glittery blue cloak and a tiara made of Ice and royal blue heels.

## Personality

Ingvild is a kind and friendly person and enjoys singing as is shown when she sings at the fountain and for Issei and his group. Ingvild is also shown to love seeing the ocean and going on beaches with her friends. Unlike her fellow members of the Leviathan clan or any other descendants of the original Satans and akin to Vali, doesn’t have any fanatic arrogance in her heritage as a Satan's descendant nor does she desire world domination like Katerea and the other descendants with the exception of Vali.

She quickly fell in love with Issei, as was revealed by her song in the battle against Nyx. She is even shown to be a little jealous of Issei's relationship with his harem such as when she and the other girls caught him with Akeno and Koneko, even thinking about acting like them despite considering it embarrassing. Her perversions later grew to the point where she is perfectly comfortable with wearing skimpy outfits, being felt up by Issei and even seducing him.

She also appears to be quiet, shy and soft-hearted. She can be very observant, remembering what Meredith said to Issei before she attacked him when the other characters were preoccupied with discussing Issei's condition.

As noted by Issei once the two had gotten to know one another, despite Ingvild's exceptional talent, she still works hard for the sake of her friends, putting others before herself.

After spending some time in the Underworld, Ingvlid became aware of the discrimination Half-Blood Devils endure regularly, realizing she was protected due to to her connect to the original Satans. She desires to create an Underworld where all Devils are accepted regardless of their background. This especially extends to her daughter and step children, which mostly consist of Hybrid Devils.

She cannot stand it when someone insults them for being Hybrids and will react violently if they do so.

## History

Ingvild was born as the daughter to a Human and a Devil from the Leviathan Clan and was living in the human world, in a seaside city in Europe. At some point in the past, she ended up with the devil sleeping disease that made her enter into a deep sleep and her parents quickly contacted the Leviathan nobles and sent her to the Underworld in an attempt to cure her.

Only the noble Devils that were a part of the previous Satan Leviathan faction knew about this information. Those noble Devils hid her in their own territory, keeping her presence secret from the current government and even to Ingvild's relative Katerea Leviathan and the Old Satan supporters who joined the Khaos Brigade.

She continued to sleep for a hundred years. She awakened due to the manifestation of her Longinus, Nereid Kyrie.

After Ingvild and her Longinus were awakened, the Devils that hid her knew that they couldn’t keep her under their control and contacted the current government and Grigori who took care of her and analyzed Ingvild's Longinus. After this, she was kidnapped by Nyx and put under the goddess' mind control.

## Powers & Abilities

**Immense Demonic Power:** As a descendant of the original Leviathan, Ingvild has impressive demonic powers, which according to Rossweisse's measurements is equal to a Satan-Class Devil or higher, being that her demonic power could resist against the brainwashing magic cast on her by Nyx. Despite having little to no practice, she has impressive control of her demonic power, being able to summon a total of ten thirty-meter water dragons, which each released an impressive aura. Rossweisse noted that she is naturally talented in controlling her powers. During training, Roygun noted that her strength lies largely in the fact that she can use her enormous amount of aura to compete with almost any opponent on an offensive basis. After receiving the relic of the original Leviathan her abilities were further enhanced. Issei likens her to a female Vali in terms of talent inherited from the original Satans. After the Evie War and Rating Game match against Sirzechs, she was recognized as a Super Devil and became known as the **Strongest Queen** (along side Verrine). It was even stated that she is capable of contending with Issei in DxD with his Dragon God aura flowing through him.

* **Sea Serpent of the End** (掉尾の海蛇龍, *Tōbi no Umihebi Ryū*) : As a descendant of the Leviathan Clan, Ingvild can control the sea and draw large amounts of water. At full power, she's capable of summoning floods, drowning whole cities and creating a snake-shaped Dragon made of water. Originally, Ingvild wasn't able to use this ability but gained access to it after coming into possession of the relic of the original Leviathan. Under Aquaman’s tutelage, her control increased to where she can do more precise actions with water, such as increase water pressure, manipulate other liquids, etc.
* **Elemental Demonic Power**: Ingvild specializes in the water and ice element’s, which she can use to create ten or more enormous water dragons and other constructs. Her power is also capable of nullifying or overpowering the elemental powers of others.
* **Defensive Magic**: She has been shown to be able to use a multi-layered defensive magic circle built with her vast demonic power.
* **Teleportation**: She has demonstrated the ability to teleport herself.

**Enhanced Magic Power:** From the Bishop trait of her Queen Piece, Ingvild can enhance her magic and demonic powers.

**Enhanced Offense and Defense:** From the Rook trait of her Queen Piece, Ingvild has both strength and defensive enhancements, giving her enhanced strength and defense.

**Enhanced Speed:** From the Knight trait of her Queen Piece, Ingvild has speed enhancement, increasing her speed.

**Expert Hand-to-Hand Combantant**: After her rigorous training with Black Canary, Ingvlid became a very skilled martial artist, regularly trading blows with Xen and Kory in sparring sessions. She battled Vali and Grayfia on separate occasions and held her own before having to resort to other tactics or her Balnce Breaker.

**Stealth Expert:** Ingvild has shown to be capable of vanishing without leaving a single trace, as Issei didn’t even feel her presence after leaving.

**Flight:** Being a half-Devil, Ingvild can fly using her 8 wings.

## Equipment

**Nereid Kyrie** (, *Nereisu Kirie*): Ingvild's Sacred Gear, that is one of the new High-tier Longinus, which allows Ingvild to control Dragons and even the Sea itself, although the former is stronger, while the latter is still improving. Nereid Kyrie can enslave Dragons and those who possess Dragon-type Sacred Gears, weakening Issei enough to dispel his Crimson Armor, potentially affecting his Diabolos Dragon, as well being able to potentially control the Dragon Gods. Its power to manipulate the sea can allow her to control the ocean to sink an urban area or a country, Nereid Kyrie could potentially even become a Sub-Species that control lakes. As a High-tier Longinus, it has the destructive potential to destroy the world.

* **Goddess of the Aquarius Dragon**: Ingvlid’s Balance Breaker. It strips her nude and takes the form of water like dress with Scale Mail-like armor, along with a Trident of water and Dragon Wings made of Ice.

* **Paipod** (, *Paipoddo*): Also known as **Breast Song Reinforcement**. By using Issei's Diabolos Dragon God as a conduit, Ingvild can empower Issei and his allies who are present. The song can be heard through the breasts of women as the area is bathed in lavender light particles.

**Queen Piece** (女王の駒, *Joō no koma*): Ingvild was reincarnated using the Queen Piece, which grants her the traits of a Rook, Bishop, and Knight.
