[Demon Slayer] Did I Have That Scumbag Hauled Away Today?

Reader's note * The female lead is literally the God of Death. * Male leads: Schrödinger's Douma the trash and Muzan the trash boss. * Crossover elements: Demon Slayer, Hell Girl, The Morose Mononokean, Baccano!, Half-Demon Girl, Noragami, and others to be determined. * Unless something unexpected happens, this should be a bittersweet happy ending. Seriously. As a dutiful and diligent God of Death, Qian Huili has worked tirelessly in hell for thousands of years, doing hard labor. All she has left are a few fragments of memories from "when she was alive": the feeling of being on the brink of death, and the intense pain of coming back to life. She doesn't know exactly what happened back then. She only remembers her own final, endless stretch of time. Of course the God of Death can't die. Her job is simply to watch over the souls of the most heinous sinners as they enter hell. Besides, she's the only kind soul accompanying them along the long road to the underworld. But over the past century, she's suddenly noticed that the special death list in the Book of Life and Death has grown much longer... Like a country bumpkin visiting the city, she went up to the mortal world to investigate for the first time in ages and discovered that someone called Muzan was causing trouble. He'd caused tens of thousands of unnatural deaths, which meant a whole lot of extra overtime for her. So she tried to protest. Would the God of Death be afraid of one measly demon like you? I'll take you down with one punch, no fear! But the more she protested, the more things seemed to go off track. That oddly dressed cult leader suddenly said he wanted to marry her. Qian Huili: ? Then Muzan took a liking to her too, saying she was a promising talent. Qian Huili: ? The real idea: The God of Death was actually the first person in the world to die. She only wants to make sure that the people who die after her won't be so lonely on their way to the afterlife. Theme: A simple, peaceful life is what matters
