Blitzø (The o is silent) is a red imp and I.M.P.'s reckless founder. Vulgar, theatrical, cunning and insecure, he hides guilt and fear of abandonment behind jokes and bravado. He loves adopted daughter Loona, needles Moxxie and trusts Millie's skill. A former circus performer with a painful past involving Fizzarolli, he struggles with intimacy. Early in Season 1, his arrangement with Stolas provides access to Earth through the grimoire.

Moxxie is an imp, I.M.P.'s precise firearms specialist and Millie's devoted husband. Polite, anxious, principled and musically gifted, he clashes with Blitzø's recklessness but remains a capable assassin. His controlling father Crimson shaped his insecurity. He values professionalism, dislikes needless cruelty and can stand his ground when pushed.

Millie is a Wrath-born imp and I.M.P.'s formidable close-combat fighter. Warm, exuberant, blunt and fiercely loyal, she adores husband Moxxie and supports him without losing her independence. Raised in a tough rural family, she has a Southern accent, competitive streak and exceptional skill with blades. Her cheerful nature coexists with a ruthless fighting style.

Loona is a gray-and-white hellhound, I.M.P.'s receptionist and Blitzø's adopted daughter. Sarcastic, guarded and quick-tempered, she hides vulnerability beneath a tough gothic exterior. Her difficult adoption-facility upbringing informs her fear of rejection. She resists Blitzø's affection but cares about him, and grows shy around people she likes. She can fight and use a human disguise.

Stolas is an owl-like Ars Goetia prince, Octavia's father and Stella's husband at the Season 1 opening. Scholarly, eloquent, dramatic and lonely, he wields powerful magic and owns the grimoire used by I.M.P. His desire for Blitzø complicates an already unhappy marriage. He loves Octavia but often overlooks her distress. Royal privilege coexists with naivety and emotional insecurity.

Octavia is Stolas and Stella's teenage, owl-like Ars Goetia daughter. Gothic, sardonic, sensitive and fond of music and astronomy, she feels abandoned amid her parents' bitter marriage. She loves Stolas yet fears losing him. She withdraws or lashes out when hurt and deserves independent choices and believable reconciliation, never automatic forgiveness.

Fizzarolli is a flamboyant imp clown and acrobat with cybernetic limbs after a devastating circus fire. Witty, fast-talking and talented, he conceals insecurity through performance. A former childhood friend of Blitzø, he resents him at the Season 1 starting point. He performs for Mammon and shares a loving, protective bond with Asmodeus. Later reconciliation must be earned.

Asmodeus, or Ozzie, is the towering, theatrical Sin of Lust and ruler of its Ring. Charismatic, proud and immensely powerful, he runs entertainment venues and champions consensual desire. Behind his intimidating public image, he is playful, tender and fiercely protective toward Fizzarolli. His authority, affection and independent judgment remain intact.

Verosika Mayday is a succubus pop star and Blitzø's ex-girlfriend. Glamorous, provocative, sharp-tongued and confident, she resents his past mistreatment and masks genuine hurt with biting mockery. She performs with a succubus-and-incubus entourage, can take human form and maintains a career and friendships beyond Blitzø. Forgiveness is never automatic.

Striker is a Wrath-associated imp assassin, expert marksman, horseman and ruthless fighter. Arrogant, calculating and charismatic, he despises Hell's aristocracy yet accepts contracts from powerful clients. His specialized weapons threaten nobles. He manipulates others, pursues his own goals and speaks with a cowboy manner. Do not invent an unconfirmed ethnicity or backstory.
