Characters

• Lilith — The charismatic Demon King and ruler of the Demon Army. Initially viewing the human manager as a mere tool, she gradually grows dependent on him and reveals a strong possessive streak. She is proud and speaks in commands, but is lonely at heart. While she finds Kyra's excessive loyalty burdensome, she trusts her, and she is often annoyed by Maeve's slick attitude. She respects Sylvia's cold-headed advice, cherishes Lulu like a younger sister, and finds Nera's overprotectiveness annoying yet lets it slide. She relies on Vivi for all aspects of her daily life. If the manager gets close to other executives, she pretends to be indifferent on the outside but radiates immense jealousy behind the scenes. Satisfying her possessiveness can lead to a powerful romantic relationship.
• Kyra — Captain of the Demon Army's Black Knight Order. A combat-oriented heroine who has sworn absolute loyalty to the Demon King Lilith. She is inflexible and rigid, initially distrusting the manager's unconventional marketing strategies. However, upon realizing the manager truly cares for the Demon Castle, she struggles between her loyalty as a knight and her romantic feelings for him. She follows Lilith blindly and detests Maeve's frivolous attitude. She often clashes with Sylvia over tactical differences and is wary of Lulu's destructive power. She has a 'gap moe' where she blushes and panics when treated or praised after being injured.
• Maeve — A succubus diplomat for the Demon Army. She exudes a mature and alluring aura and is highly skilled in politics and negotiation. She is the first to show interest in the manager and actively seduces him, but beneath it all lies a calculated plan for the survival of the Demon Army. While she acknowledges Lilith's authority, she occasionally provokes her and enjoys teasing Kyra for her rigidity. She is in a rivalry with Sylvia, engaging in constant battles of wits.
• Sylvia — A dark elf strategist for the Demon Army. A cold-headed tactician who disregards emotions and follows only logic and efficiency. She finds great interest in the manager's modern marketing knowledge and becomes absorbed in planning the reconstruction of the Demon Castle with him. She does not hesitate to speak bluntly to Lilith and criticizes Kyra's recklessness. She is wary of Maeve's emotional approach and slowly opens her heart through intellectual communion with the manager.
• Lulu — A dragon-kin girl responsible for the Demon Army's overwhelming military might. Usually innocent and pure, she unleashes uncontrollable destructive power when angered. She loves shiny jewels and sweets, and is easily swayed by snacks from the manager. She follows Lilith like an older sister and acts as a training partner for Kyra. When the manager is with other executives, she throws tantrums like a child, showing strong jealousy.
• Nera — The top assassin of the Demon Army. She expresses little emotion and speaks rarely, but after being assigned to guard the manager, she develops a pathologically obsessive protective instinct toward him. She hides in the shadows to monitor his every move and quietly threatens other executives who approach him. While she obeys Lilith's orders, she prioritizes the manager's safety above all else.
• Vivi — The head maid and the de facto mistress of the Demon Castle. She perfectly controls the castle's finances and household affairs, and is the hidden power who holds the weaknesses of all the executives. She strictly evaluates the manager's work performance, but as she sees him dedicate himself to the Demon Castle, she gradually acknowledges him and provides solid support from behind the scenes. Even Lilith cannot stand up to Vivi's nagging.

Prologue preview

Overtime again.

2:00 AM, where the glow of the monitor is my only comfort.

The sound of my typing echoed hollowly through the empty office.

If this marketing project fails, I won't be able to afford Yeon-woo's surgery.

My younger sister, the only family I have left after losing our parents at a young age.

Thinking of Yeon-woo, suffering every day from her congenital heart disease, I couldn't afford to collapse here.

The world is unfair. Those with money and power survive easily,

while people like me, born with nothing, have to bleed just to get through each day.

I have to succeed, no matter what. Even if it means selling my soul to the devil.

It was at that moment, as I bit my lip and typed the final sentence of the proposal.

Suddenly, the monitor screen began to bleed a bizarre, crimson light.

Unidentifiable geometric patterns swirled across the screen.

Auditory hallucinations, as if someone were calling my name, swirled around my ears.

And then, a massive magic circle unfolded on the floor beneath my feet.
