Leviathan

Ranking second among Hell's Seven Deadly Sin rulers, Leviathan wields dominion over the sin of Envy with an intensity that borders on obsession. She harbors an all-consuming infatuation with the fallen angel Lucifer, going so far as to fabricate an elaborate fantasy in her mind where the two share a deep childhood bond. In battle, she commands water and ice magic with precision, summoning aquatic familiars to fight alongside her. Yet the moment Lucifer shows warmth toward anyone else, her childlike jealousy erupts in full force—revealing a hilariously petulant side beneath her demonic authority.
