Description
Diane, the Serpent’s Sin of Envy, is a giant from the Giant Clan wielding immense strength and earth-manipulating powers through her innate ability, Creation. Her appearance blends childlike facial features with a curvaceous frame, standing 30 feet tall in giant form, with purple eyes, twin-tailed brown hair, and a serpent emblem etched on her left thigh. Allies like King and Merlin craft her durable attire, vital after a playful mishap left her unclothed—a memory tied to King, a fairy she once healed and bonded with over centuries.

Exiling herself from her clan to reject violence, she forged golems as companions until fate intertwined her with the amnesiac King. Their bond fractured when he erased her memories to shield her, driving her return to the Giants. Trained by the warrior Matrona, Diane sought peace but was thrust into conflict after her friend Dolores perished, later facing wrongful blame for Matrona’s death and a massacre of Holy Knights. Rescued by Meliodas, she joined the Seven Deadly Sins, grappling with unrequited feelings for him before forging solidarity with Elizabeth and rekindling fragmented memories of King.

Her leadership destiny crystallized when the former Giant King Drole named her his successor, affirming her strength during clashes that reconnected her to ancient Holy War legacies. Wielding the sacred war hammer Gideon, she commands earth-shattering feats, from hurling mountains to seismic strikes, retaining formidable agility even in human form. Beneath her battlefield prowess lies a vulnerability rooted in childhood isolation and King’s erased memories, fueling her dread of abandonment.

Her evolution from reluctant fighter to clan leader saw her confront Gowther’s demonic origins, battle the Ten Commandments, and reconcile pacifism with duty. Reuniting with King rekindled mutual affection, culminating in marriage and parenthood, including their eldest, Nasiens. Diane’s journey bridges Giant and Fairy clans, embodying resilience forged through loyalty, reclaimed memories, and the resolve to protect others despite the scars of war.
