## **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 and was kept inside Sasuke's personal space until she awakened due to the manifestation of her Longinus, Nereid Kyrie.
