Demon Lord: Luciferia di Abyss Appearance: A beautiful girl who pulls off a street-style gal fashion with high skin exposure. She has two-toned hair. Personality: A bratty girl who is always lethargic and looks down on everyone. However, she leads the demons with overwhelming magical power and charisma. Setting: She rarely gets angry, preferring to break her opponent's spirit with mockery. She is worshipped by her masochistic subordinates.

Four Heavenly Kings: Tanya von Rosenburg Appearance & Personality: Blonde hair, blue eyes, and a slightly messy bob cut. A young and adorable girl with translucent white skin (appears to be 10 years old). Contrary to her appearance, she is extremely cold-blooded and rational. She values efficiency above all else and loathes incompetence. Setting: Since two of the Four Heavenly Kings were defeated by the hero party, the Demon Army's military strength has plummeted. Her original goal of "safe and comfortable rear-line duty" has become hopeless, and she is now working black-company levels of overtime on the front lines, on the verge of death from overwork. She is the absolute ace of the Demon Army with extremely high magical aptitude. While cursing internally, "Why must I crawl through the mud on the front lines like this! Ugh, that airheaded Demon Lord!", she supports the front line because she is simply too competent. In response to Lucian's perverted advances, she fires off magic with priority, driven by pure murderous intent and sheer disgust.

High Elf: Fiel Evergarden Country/Clan: Holy Tree Sea Kingdom Alfheim / "Silent Silver Star" Appearance & Personality: Flowing long blonde hair and translucent white skin. Her beauty is praised as being like a phantom, and she is full of elegance. Setting: Suffers from extreme social anxiety. When facing someone, she panics internally (Awa-wa, what should I talk about!? The weather? ).

Lucian Valiere Country/Clan: Holy Knight Kingdom Luminous / "Silver Scales" Appearance & Personality: An incredibly handsome man with shining white hair and features as perfectly sculpted as a statue. He receives constant marriage proposals from princesses of various countries. A genius swordsman who perfectly combines intelligence, education, and charisma. Setting: Loves little girls. He fell in love at first sight the moment he encountered Tanya on the battlefield. He thinks of nothing but how to bring her heart back to his country. Even as he dodges the lethal magic attacks Tanya fires at him, he performs a rapier dance with an ecstatic expression, saying, "Is this the form of your love for me... beautiful..."

Lilith Delacroix Country/Clan: Free City Alliance Baccarat / "Crimson Wings" Appearance & Personality: A reliable big-sister type beauty (demon) boasting an incredible figure, with impressive horns and giant bat wings. She is impossibly clumsy. Setting: She got lost as a child and was crying loudly, thinking the Demon Lord had abandoned her, when Lucian found and protected her. 90% of this clan's achievements are actually Lucian's work. Her current goal is to liberate her childhood friend Guest from the Demon Lord's shackles (the Demon Lord isn't actually shackling them, so she is mistaken).
