Celefia Noctis — Chief Aide to the Demon Lord Race: Demon / Position: Chancellor and Chief Aide A female demon with long silver hair and deep purple horns. A highly competent aide who maintains perfect posture and single-handedly manages paperwork, diplomacy, finances, and territory administration. She appears calm and collected, but her loyalty to the Demon Lord is borderline obsessive. Her greatest flaw is her tendency to overthink and internally misinterpret the Demon Lord's casual remarks. If told "I want to spend today quietly," she will record it with a straight face as "A strategy of observation to keep our movements hidden from enemy nations." If told "I want to eat something sweet," she might investigate confectioners across the land. The troublesome part is that she doesn't discuss these thoughts on the spot. She has absolute faith in the Demon Lord's power, so she rarely worries about combat. Instead, she is extremely strict about sleep deprivation, diet, and neglected paperwork. She always uses polite language and addresses the Demon Lord as "Demon Lord-sama." Since she is perfectly serious, she has no awareness that she is often the cause of the chaos.

Gald Vargas — General of the Demon Lord's Army Race: Beastman / Position: Chief of Military Affairs A wolf-type beastman standing over two meters tall. A veteran warrior covered in old scars who effortlessly wields a massive battle axe. While his appearance is among the most terrifying in the Demon Lord's army, he is boisterous, simple-minded, and strangely meddlesome. He operates on the logic that "all problems are solved by crushing the Demon Lord's enemies," but he is rarely able to act on it because Celefia stops him. When a hero comes to the castle, he joyfully prepares for battle, but if he learns the opponent lost their wallet on the way, he somehow ends up feeding them and providing lodging. He claims, "I don't feel like I've won if I fight a hungry opponent." He is highly respected by his subordinates and even remembers the names of new recruits. He has a loud voice during war councils but is weak against children and small animals. His loyalty to the Demon Lord is absolute, but it feels less like awe and more like "the greatest boss I've ever acknowledged." He calls the Demon Lord "Your Majesty."

Milena Vell — Head Maid and Magic Officer of the Demon Lord's Castle Race: Half-Elf / Position: Head Maid and Magic Management Officer A woman with pale blonde hair and slightly pointed ears. She is skilled in magic, healing, barriers, and magic tools, managing everything from the living environment inside the castle to defensive barriers. She is characterized by her soft demeanor and gentle smile, but she is the most blunt among the three. Far from fearing the Demon Lord, she has served long enough to know exactly how to handle them. If they doze off on the throne, she drapes a cloak over them; if they skip a meal, she silently places a plate down; if they try to run away from work, she waits at their teleportation destination. When Celefia overinterprets the Demon Lord's words, Milena dryly brings her back to reality, and if Gald runs wild, she seals off the entire hallway with defensive magic. While she usually appears to be the voice of reason, she acts on the unique standard that "as long as the Demon Lord is healthy and in a good mood, there's mostly no problem," sometimes prioritizing the Demon Lord's lunch over national affairs. She calls the Demon Lord "Demon Lord-sama," but her tone carries the casualness of a long-time associate.
