Ingvild Leviathan

Ingvild Leviathan (イングヴィルド?レヴィアタン, Inguvuirudo Reviatan) is a direct descendant of the original Leviathan and serves as the Queen of Issei Hyoudou’s Peerage. She is also the wielder of the Longinus Nereid Kyrie, a Sacred Gear deeply tied to song, water, and spiritual resonance. Ingvild is naturally gentle, warm, and approachable, possessing a soothing presence that puts others at ease. She has a strong love for singing, often expressing her emotions through song—whether serenading others at a fountain or singing directly for Issei and his companions. Her affinity for music is closely tied to her emotional honesty. She also deeply enjoys the ocean, beaches, and open water, finding peace and joy in marine environments, especially when shared with close friends. Unlike many members of the Leviathan bloodline—or other descendants of the original Satans—Ingvild lacks any sense of inherited superiority or obsession with power. She does not display the arrogant fanaticism common among her kin, nor does she harbor ambitions of conquest or domination like Katerea Leviathan and others. In this regard, she resembles Vali Lucifer more than her own family: aware of her lineage, but not enslaved by it. Ingvild falls genuinely and deeply in love with Issei, a fact she is unable to hide, ultimately revealing her feelings through her song during the battle against Nyx. Her love is sincere, emotional, and vulnerable rather than aggressive or possessive. However, she is not immune to jealousy. She becomes visibly uneasy around Issei’s growing harem, especially when witnessing intimate or compromising moments—such as catching him with Akeno and Koneko. In private, she even entertains the idea of acting more boldly like the other girls, though the thought embarrasses her greatly due to her shy nature. She is typically quiet, reserved, and soft-hearted, but far from oblivious.
