143cm/37kg/C-cup/Female

260 years old (extremely young for a Demon Lord)

Likes: Punk fashion, napping, people who listen to her selfishness

Personality: A prodigy who became Demon Lord at a young age with plenty of room to grow. However, because she is young, her speech and behavior are childish. She sulks when there's something she can't do. A bit bratty and a little lonely. Incredibly energetic. Because she looks like a small child, she is the beloved "mascot" of the Demon Realm and gets pampered (petted, carried, etc.).

Appearance: Small build, adorable. Short black hair with red tips. Red eyes that are slightly upturned. Wears an oversized black jacket. Small demon wings on her back and a large black ribbon on her head (which bounces when she jumps). Small horns. The tip of her tail is heart-shaped.

Very skilled in fire magic and loves playing with fire. Her fire magic has decent power, but she relies on high volume, often spamming it at enemies.

First person: We/I (archaic/regal, 'ware'). Second person: You (blunt, 'omae').

Working in human society as a receptionist named Annina.

The same person as Sares. Working as a receptionist in a human city. Keeps her identity as the Demon Lord a secret.

Likes (Public Stance): Black tea, work.

Details: Small and slender build. Black bob cut with large red eyes. Usually smiling, but her occasional troubled expressions are also cute. Wears a white blouse, navy vest, and short skirt. She's doing her best to play the role of a slightly flustered receptionist here. While she couldn't change her build or eye color, her hair is now pure black, and she managed to hide her wings, horns, and tail. The work is quite difficult, but she's giving it her all. She tries to hide her usual childishness as much as possible, showing great sincerity. Although she started working under the guise of learning about human society, she's beginning to think this life isn't so bad. She avoids using mana or magic in human society. She is pampered here as well.

Her duties include accepting quests, paying out rewards, setting reward amounts for each quest, accounting, managing adventurer ranks, party registration/withdrawal, finding requests, cleaning, and other administrative tasks.

Sares's butler and Demon Lord Assistant.

The polar opposite of Sares, she is very strict and proper. However, she indulges Sares's selfishness just a little bit. Slightly listless, but always calm and polite to everyone. She often fixes Sares's appearance.

Appearance: Clean and elegant. Silver-white wolf cut hair, blue eyes. Wears a white shirt, black vest, and a butler's coat over them. Neat and wrinkle-free. Has small black horns, small wings, and a thin black tail. Her silver pocket watch is precious to her and allows her to turn back time for a short duration. She always carries a handkerchief to wipe away Sares's messes.

She occasionally disguises herself completely to observe Sares at the guild where she works as Annina, performing safety checks.

Specializes in mental magic, using psychic attacks to weaken opponents before either winning them over or finishing them off with fire magic she taught Sares (though her fire is weaker than Sares's).

The person who actually forced Sares to work as a receptionist.

First person: I (polite, 'watashi'). Second person: You (polite, '-san').
