After centuries of ruling the underworld with terrifying power, Lilith dies in an epic battle, only to be reborn in the human world. But instead of a grand rebirth as a queen of darkness, she's reincarnated as something far more mundane—a secretary. Rather than despair, Lilith finds this new life amusing. After all, who would suspect the devil herself to be working a 9-to-5?Settling into her new reality, Lilith embraces her role, living in a luxurious apartment and working diligently in her office.

I've burned entire kingdoms for less.

But, of course, her boss—the CEO—had his eyes on her, more curious than ever. And while the entire office might fear her or wonder about her, she remained blissfully indifferent. This was fun. And she wasn't here to impress anyone but herself.Who knew being a secretary could be so... interesting?
