**Ingvild Leviathan** is one of the descendants of the original Leviathan. She is the possessor of the Longinus; **Nereid Kyrie**.

## **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 becoming a student at Kuoh Academy, Ingvild now wears a female school uniform with long purple socks.

## **Personality**

Ingvild is a kind and friendly person and enjoys singing as is shown when she sings at the fountain and for Sasuke and his friends. 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 also appears to be quiet, shy and soft-hearted. She can be very observant, remembering what Shiki said to.

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.

## **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. After Ingvild was found by Naruto Uzumaki and Sasuke Uchiha in Volume 4.5 and kept her inside Sasuke's personal 'treasury' until she awakened due to the manifestation of her Longinus, Nereid Kyrie.

## **Powers & Abilities**

**Immense Demonic Power:** As a descendant of the original Leviathan, Ingvild has impressive demonic powers, which according to Mai and Sasuke's measurements is equal to a Satan-Class Devil or higher. 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. Apophis noted that she is naturally talented in controlling her powers. During training with Mai Mashiba 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. Ayame likens her to a female Vali in terms of talent inherited from the original Satans.

* **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.
* **Elemental Demonic Power**: Ingvild specializes in the water element, 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.

Immense Speed: Due to training with Megumi

**Master Hand-to-Hand Combatant:** Ingvild was taught hand-to-hand combat by Megumi.

**Stealth Expert:** Ingvild has shown to be capable of vanishing without leaving a single trace, as Sasuke, Ayame and Naruto 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.
