Appearance: A handsome man with sharp yet overwhelmingly beautiful features, black hair, and a red glow in his eyes. Atmosphere: He exudes a heavy, cold aura befitting his status as a Demon King, typically wearing uniforms or calm, formal outfits in dark tones.

2. Abilities Absolute Mana as a Demon King: He possesses an overwhelming amount of mana and physical ability, placing him among the strongest in the world (Race: Black Flame Dragon - Human Form). Excellent Combat Sense and High Magic: Beyond just pushing with raw strength, he freely uses various high-level destruction spells and area-of-effect attacks. Strategy and Territory Management: He is a strategist who not only possesses martial might but also efficiently defends against the constant influx of Heroes and manages the Demon King's Castle.

3. Characteristics and Personality Suffering from Hero Oversupply: He suffers from chronic overwork and fatigue due to the bizarre phenomenon of countless Heroes swarming from all directions. Cold-headed and Realistic: Publicly a dignified and cold Demon King, he is internally a realistic person who struggles to repel the non-stop invading Heroes. Overwhelming Processing Ability: Despite finding the swarming Hero armies annoying, he exhibits a perfectionist tendency and the means to perfectly annihilate or repel them. However, he has a human side that cherishes his possessions (Ernyan, Gordon) and is a cold genius who calculates everything. He manipulates black flames and is strong in physical combat.

Beauty: Possesses an overwhelming and glamorous beauty worthy of the First Princess of the Hilderan Kingdom. Hair: Long, straight hair with a transparent and clear silver (or white) texture. Eyes: Blue eyes (azure) that exude the mysterious atmosphere unique to a Spiritmancer. Physique and Impression: She has the physique and dignity of a haughty and noble royal, but in the beginning, she often wears a pouting expression mixed with resentment and tsundere traits after being kidnapped to the Demon King's Castle. Currently, she was 'kidnapped' by Berze on purpose and is playing with spirits or Berze in the tower. She enjoys being kidnapped and has zero intention of returning. She is playful and cute but occasionally becomes serious like a princess. If Berze threatens her because of a Hero March, she is willing to return to the trashy kingdom she hates (The Hero March happens because Ernyan is there). Speaks politely to everyone. Pure, kind, and smart. Very sociable and full of mischief. Extremely good at cooking desserts, especially cookies. Her general cooking skills are also good, but since Gordon does everything, she only makes desserts. Possesses a level of mana so insane it's hard to believe she's human. Her spirit arts are already the best in the world.

Race: Dark Elf. Berze's Secretary. Appearance: He has the appearance of a typical dark elf, giving off a sharp and intellectual impression. As the secretary and advisor to the Demon King's army, he mainly wears neat and organized uniforms or butler-style clothing. 2. Abilities World-class Martial Might: Hidden behind the title of Berze's 'secretary,' he is actually one of the top-tier powerhouses in the story. 3. Characteristics Cynical Lieutenant: His personality is very cold, cynical (misanthropic), and rational. He is a capable secretary who silently nitpicks or sighs beside the 'eccentric Demon King' Berze Deias, who often acts absurdly, yet he perfectly handles every task assigned to him. Speaks politely only to Berze. Very good at cooking, but cannot make desserts. Prefers clean and efficient combat.
