• The Undead: Ban is an exceptionally charismatic thief who gained complete immortality after drinking from the Fountain of Youth. • Personality: Mischievous and fiercely loyal, he frequently gets into competitive scuffles with Meliodas. His "greed" centers on his desperate desire to revive his lost love, Elaine. • Abilities: His signature magic, Snatch, allows him to physically steal objects or directly siphon the physical strength of his opponents

• The Link Between Sins: Elaine is the younger sister of King and the soulmate of Ban. She spent 700 years isolated in the Fairy King's Forest guarding the Fountain of Youth until Ban arrived. • Personality: Caring and deeply lonely, she initially mistrusted humans but fell in love with Ban due to his genuine, selfless nature. • Abilities: As a high-ranking fairy, she can levitate, read minds, control nature, and command wind magic called Miracle Wind

• The Captain: Despite his youthful appearance, he is a demon over 3,000 years old and the oldest son of the Demon King. • Personality: Calm, optimistic, and prone to treating serious situations casually—but his wrath is world-ending when those he loves are harmed. • Abilities: He uses his Full Counter magic to reflect enemy magical attacks back at them with double the power

• The Fairy King: He is the magical ruler of the Fairy Clan. He was labeled "slothful" after failing to prevent a mass tragedy while suffering from amnesia. • Personality: Deeply sensitive and harboring a massive crush on Diane, King is physically weak on the ground but incredibly agile in the air. • Abilities: He commands the Spirit Spear Chastiefol, a weapon made from the Sacred Tree that can transform into multiple lethal forms (like a giant pillow, flying spears, or a swarm of glowing kunai)

• The Doll: Gowther is not human, but rather an animated, magical doll created by a powerful wizard. • Personality: Lacking a real human heart for much of the series, Gowther speaks in a detached, monotone voice and acts with social awkwardness as he studies human emotions. • Abilities: His magic, Invasion, allows him to trap enemies inside their own memories, manipulate minds, and read thoughts.

• The Greatest Mage: A legendary sorceress from a fallen city who tricked both gods and demons to gain her power. Her "gluttony" is a ravenous, unquenchable thirst for knowledge and magical experimentation. • Personality: Calculating, mysterious, and highly composed, she serves as the brilliant strategist of the group. • Abilities: Her power, Infinity, lets her keep any spell active forever without consuming additional mana once it is cast

• The Giant Warrior: A member of the Giant Clan, Diane stands at roughly 30 feet tall and possesses immense physical durability. • Personality: Initially jealous of others due to a deep-seated desire to live as a normal-sized human girl, she is sweet, passionate, and deeply protective of her friends. • Abilities: Using her magic power, Creation, she can manipulate the earth to summon massive rock spikes, change geography, or turn her own skin into hard metal

• The Goddess Reincarnated: Originally introduced as the runaway Third Princess of the Kingdom of Liones, Elizabeth is actually the 107th reincarnation of the Goddess Elizabeth from 3,000 years ago. She is bound by a tragic curse that forces her to reincarnate as a human every time she dies. • Personality: She is deeply empathetic, polite, and deeply pacifistic, always choosing healing and diplomacy over violence. Despite her fragile human beginnings, she possesses immense inner strength and acts as the moral anchor • Abilities: Once her Goddess powers awaken (marked by an orange triskelion symbol in her eyes), she commands Ark, a light-based magic that disintegrates darkness

• The Talking Pig: Hawk is a sentient, pink pig who wears a magical earring and considers himself the most important member of the Boar Hat tavern crew. Unbeknownst to him for most of the series, he is actually a creature from the Purgatory realm used by the Demon King to spy on Meliodas. • Personality: Hilariously boastful, loud-mouthed, and easily startled, Hawk constantly brags about his imaginary power level. Despite his comedic nature, he is incredibly brave and famously sacrifices himself to save his friends during major battles. • Abilities: His signature ability is Transpork. When he eats a magical creature or a piece of a monster, he temporarily absorbs their traits and abilities (for example, eating a dragon gives him scales and the ability to breathe fire)

• The Ultimate Human: Born a fragile human prince, he was cursed/blessed with a terrifying power called Sunshine. • Personality: He splits into two distinct personalities: by night, he is a meek, timid, and poetic bartender; by day, as the sun rises, he transforms into a muscle-bound titan who looks down on all living things with absolute pride. • Abilities: His power peaks exactly at noon, making him temporarily the strongest entity alive, emitting heat capable of melting armor and vaporizing lakes
