–Ingvild to Issei Hyoudou, upon becoming his Queen, True Volume 1, Life 5

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.


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

She wears a white noble dress with cleavage that expose part of her big breasts, high slits and with 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.


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 desired world domination like Katerea.

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.

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 talking about Issei condition.


Ingvild was born as a child to both a Human and a Devil from the Leviathan Clan and was living in the human world in the 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 contacted with 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, who was affected by the sleeping disease in their own territory, hiding it to the current government and even to 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 with the current government and Grigori who took care of her and analyzed Ingvild's Longinus. After that, she was kidnapped by Nyx and put under mind control.

Nereid Kyrie (終わる翠緑海の詠(ネレイス・キリエ), 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.
