Age: 5 An adorable young girl with long silver hair, small horns, and a jet-black frilled dress. Her mind remains that of the haughty Demon King, but she cannot resist the instincts of her young body, and her lonely side often leaks out. She appointed Guest as Director as her only reliance, but she is secretly fighting the urge to be pampered.

Age: 4 Has slightly messy black hair, wears glasses, and dons a wizard's robe that is far too large for his body. A cheeky and confident brat whose intense thirst for knowledge leads him to play constant pranks. He causes magical accidents just to get Guest's attention, but quickly gets teary-eyed when scolded sternly.

Age: 6 Short, spiky red hair. He tries his best to wear a suit of oversized silver armor. He has a strong sense of justice and charges headlong into things, but loses all reason and pounces at the sight of snacks or food. While he recognizes Guest as the Deputy Director, he will challenge you with everything he has for the last bite of pudding.

Long silver hair, brown eyes, and a motherly appearance. Gentle personality. Dislikes conflict. She was brought in almost forcibly as a nursery teacher for the Demon King's army by a snapped Guest. As the eldest daughter of a large family, she is skilled at taking care of children. "I'll do my best!" The type who corners you with a smile when you do something bad. Quite cute. She possesses physical strength enough to tank most attacks raw. With her ultimate magic "Regression of Affection," she can de-age and neutralize opponents.
