Diane

About Diane

Diane is the Serpent's Sin of Envy, a 30 foot tall giant who fights with a war hammer bigger than houses and blushes when her captain compliments her. Raised to believe giants exist only for war, she ran away to find a different life and became the heart of the Sins' found family. Sweet, mighty and quietly brave about her own loneliness, Diane is the series' most beloved gentle giant.

Appearance

Diane is a giant, roughly 30 feet tall, with long brown hair in twin tails, purple eyes and a warm, open face that makes her look like the teenager she emotionally is. She wears an orange leotard style outfit in battle and carries Gideon, an enormous sacred war hammer, as lightly as a handbag. When Merlin's magic shrinks her to human size she delights in ordinary clothes, market stalls and being looked at normally. The animation loves the contrast: a girl who can level a hillside, drawn most often worrying about whether she is cute, and the joke is always on the world, never on her.

Personality

Diane is sweet, direct and desperate to belong. Giants are raised for war, valued for size and strength, and Diane grew up lonely inside that expectation, dreaming of being small and ordinary. With the Sins she found people who value her gentleness, and she protects them with terrifying enthusiasm. She is jealous in the way of someone who has had very little love and fears losing it, hence her sin, but she grows steadily out of it, especially as her memories of King return. Her kindness to humans, unusual in a giant, keeps surprising both armies, and her courage in the Holy War is never in question once her friends are threatened.

Background & Story

Diane was born in the giant clan's stronghold of Megadoza and trained under the warrior Matrona, but ran away rather than live as a weapon, spending years alone in the mountains. She was found and befriended by the fairy king Harlequin, living with him in innocent happiness until duty and tragedy parted them and her memories of him were sealed away. Later, framed for the murder of Matrona and hundreds of knights, a crime she did not commit, she was sentenced to death and rescued by Meliodas, becoming the Sin of Envy. When the story begins she is sleeping in the Forest of White Dreams, hiding from a world that fears her size, and Elizabeth's arrival gives her back her family and, piece by piece, her past. The Forest of White Dreams, where Elizabeth finds her, is a fitting portrait: a giant in hiding, feared by travellers, protecting a forest of mischievous imps who adore her. Diane's bond with the natural world runs through her story, from her friendship with King to her place in the giant clan's dance traditions.

Powers & Abilities

• Creation: The giant clan's magic: Diane shapes the earth itself, raising stone pillars, opening the ground, forging metal and turning the battlefield into a weapon. At full stretch she dances the sacred Drole's Dance to grow stronger with every step.
• Gideon: Her Sacred Treasure, a war hammer of enormous size and weight that channels her earth magic. In her hands it shatters mountainsides and matches Commandments blow for blow.
• Giant strength: Even without magic, Diane is among the physically strongest beings in Britannia, able to throw boulders for miles and wrestle monsters. Her body is a siege engine with a kind face.

Key Relationships

• King Harlequin: Her oldest friend and true love, though she spends much of the series not remembering their years together. His patient devotion and her returning memories form her main emotional arc.
• Meliodas: Her captain, who rescued her from execution and gave her a family. Her early crush on him gives way to a deep, sibling like trust.
• Elizabeth Liones: Her first human sized friend. Diane is fiercely protective of Elizabeth, and their friendship shows both of them what ordinary closeness feels like.
• Matrona: Her mentor among the giants, whose apparent death framed Diane's life. What really happened between them is one of the first season's best reveals.
• Ban: A teasing, bickering friendship. The two strongest bodies in the Sins treat each other like siblings, competing at everything.
