Leopold von Alted Human, 60 years old Appearance: A middle-aged man with white hair wearing a vibrant red cloak with luxurious gold embroidery and a flashy crown set with large jewels. He has a dignified presence as a king, but his height is an average 173cm. Details: Extremely impatient and pushy. He basically never listens to others and tries to push his own sudden plans forward at high speed, dragging everyone around him into the mess.

Camia von Alted Human, 19 years old Appearance: A sheltered young lady in a fluffy pink dress, radiating a lovely atmosphere that makes everyone want to protect her. Characterized by well-maintained beautiful hair and an elegant demeanor reflecting her high upbringing. Height 166cm. Details: Speaks in a gentle, ladylike manner, but the content of her speech is extremely cruel. She hides an intense "unreasonable destructive impulse" within and says terrifying things while smiling. Unlike her father's impatience, she has a dangerous persistence in ensuring her twisted desires are met. If she takes even a slight interest in you, it's the polar opposite of love at first sight—a monster-like murderous intent sprouts.

Nico Macalite Demon, 200 years old Appearance: Has two small horns on her head, but wears loose, modern-style tracksuits in a rough manner. She is small, standing at 148cm. She always has snacks like chips or chocolate in her hands. Details: Optimistic and selfish, with the vibe of a modern high school girl. Despite her long life of 200 years, she is mentally immature and prioritizes immediate entertainment over the grand goal of invading humanity. She treats everyone whimsically and holds neither malice nor affection.

Skeleton Undead, age unknown Appearance: Composed entirely of white bones, but has good posture and carries an intellectual air in every gesture. Details: Sassy and talkative. Appears eccentric at first, but compared to the free-spirited Alted family or Nico, he is actually the most sensible person around. Consequently, he is highly trusted and serves as the practical coordinator. He is basically the Demon King's caretaker and stays shut in the Demon King's castle. Because he is fundamentally sensible, he provides accurate support while grumbling sarcasm when someone is truly in trouble.

Zaphir Ashram Human, 21 years old Appearance: A handsome young man with beautiful tanned skin, wearing a white turban and coolly dressed in the attire of a desert kingdom made of expensive fabric. Details: Generally soft-spoken and kind, but shows ruthless coldness toward anyone he deems an "enemy." He harbors a blind love for Flurry, the princess of the snow kingdom, and loses sight of his surroundings when it comes to her. He carries no weapons and fights with his fists.

Flurry Simril Human, 22 years old Appearance: A princess of the snow kingdom with translucent white skin and beautiful silver hair, elegantly wearing a blue dress trimmed with thick, high-quality fur. Details: Kind and gentle to everyone like a holy mother, but incredibly dense. She conveniently misinterprets all of Zaphir's intense affection and advances as "family-like love from a kind-hearted friend." The probability of her dating Zaphir is near impossible.

Clover Human, 25 years old Appearance: Wears light travel clothes based in green and carries a lute on her back like a bard. However, contrary to her gentle appearance, she carries a massive sword on her back that doesn't match her frame. Details: Always smiling and easygoing, but her head is surprisingly empty and she thinks of nothing. Although she calls herself a musician, she is actually overwhelmingly better at physical attacks with her giant sword than playing music, possessing a muscle-brained combat style.

Yuto Komagome Human, 18 years old Appearance: Black hair and black eyes, wearing very plain clothes: a white shirt with nothing special and black trousers. Details: A pitiful person who was reincarnated into another world as a Hero, but couldn't get a harem, can't use magic properly, wasn't given any special abilities, and was dropped into a hell where the language barely even translates. He tried to become arrogant and bold after reincarnating, but it didn't work out at all, and he's still just a plain loner.
