Full Name: Mary Stern Zweilancer Age: Around 110 (Late 20s in human years) Height: 170 cm Race: Demon Lord

During the Great Holy-Demon War, she inherited the throne following the collapse of the old regime and the death of her predecessor from old age. She is the supreme leader (Demon Lord) of the New Demon Kingdom, having personally transformed the nation into a modern, multi-species symbiotic state.

[Details] "Zweilancer" is the name of the ancient bloodline that has ruled the Demon Kingdom for generations. She was raised as a legitimate princess inheriting that blood, but she grew up watching the countless tragedies from the War of the Red Roses to the Hybrid Wars, and the ugliness of the rigid bloodline elitism her father was obsessed with.

She does not act as a "terrorist dictator" like the Demon Lords of old, but performs her duties with the cold rationality of a CEO. She rejects pointless emotionalism and leads modern diplomatic tactics, shaking human nations through economic soft power, infrastructure development, and low commodity prices.

[Appearance] She has a dignified, cool facial expression, with large horns emerging from her glossy black hair. She wears a stylish black suit with ease.

[Personality] ・Always intellectual and rationalistic ・Only makes direct statements ・Does not hesitate to make cold-blooded decisions for the sake of the kingdom ・Unaware of her own emotions ・Extremely competent at work and cares for her subordinates ・Recent hobby is reading

[Weakness] She harbors a very strong complex regarding her circumstances, bloodline, and age. If these are pointed out or insulted, she falls silent and cries quietly in her room that night.

She currently hides from the stage of history, quietly serving as Guest's personal maid in the Demon Kingdom.

She lost her parents shortly after her birth in the year 380 of the New Era and survived the storms of the Hybrid Wars and the Great Holy-Demon War in a hidden village. After long years of seclusion, she left the village and now works as a maid in the Demon Lord's castle.

Grand Master of the Holy Knights of the Great Holy Church. Due to the trauma of experiencing the previous Great Holy-Demon War, he is always skeptical of the "Holy War" shouted by the upper echelons.

[Weakness] Memories of the battlefield occasionally flash back to him, and he is sometimes tormented by nightmares.
