[HELL ON EARTH] DOMA X READER

[2.3: The Upper Moons]

Reminder: I am changing the plot to my liking. Do NOT comment on discrepancies.

Kokushibo POV [Present day]

"She is alive!" I passed Daki's room in the infinity castle, the twins unaware of my presence. "Gyutaro, I can feel it in my blood as well as sense it. We must bring her back here-"

"You can't. You know Muzan will kill us if we disobey him again. It's bad enough your time as an Oiran has you used to the prim and proper human norms despite you being a demon. It's time you returned to your demon heritage."

I walked into their room and they both stood up and bowed, Daki looking nervous. "You two are fools. Master has a plan, don't do anything foolish. Daki, you are to continue being an oiran. Your presence in the entertainment district will only draw her back. Then she will see Doma and our plan will be put into immediate effect."

Daki looked slightly uncomfortable. "But she was our mother. How could we murder her like that? In the place she raised us? Isn't Doma still doing his operations in Hoshu castle?"

"Mother?" I scoffed. "The second Doma turned you into demons in order to save your life was the day she stopped caring. Would she have left you that day if you were human?"

Gyutaro shook his head and looked at his sister. "Ume, you know he's right."

She looked skeptical but I knew as well as she did that she could and would not disobey Muzan. "I know. You are right. I will lead her right to Hoshu castle."

Reader POV

A week after the blood moon festival, I traveled to the Hoshu district. Hajime, a loyal follower and one of my best swordsman informed me of a demon's presence, calling them filth.

"You fools do realize I'm a demon, right?"

"Yes, but you are on our side," one said. "You are, right?"

"Yes. Clear the area, it can get messy." The two saluted me and left. I followed the scent and came to an oiran's house, recognizing it as the former inn where I had stayed with Doma centuries ago. One of the ladies knew me by the seal I carried somehow and escorted me to a room with a veil blocking me from seeing who was sitting in front of me, though I could see who it was.

"So you finally come visit me after hearing I've been luring men to their deaths, as well as women..." the person said. "Do you recognize me?"

"It's Ume," I said flatly. "And you are an upper rank. I can't help but feel proud you are stronger, but disappointed in the way you do it."

"Mother." Ume looked at me from behind the fan as the curtain lifted. "It's been centuries. I had thought surely you had forgotten me. Some tea?"

I watched her pour the liquid, narrowing my eyes at the way a droplet landed on her hand and the way she hissed in pain under her breath.

I sat down and drank the tea on the table knowing it was poisoned with something strong enough to kill a demon, though I had been building an immunity. "I would never forget someone I love. Even though they try to kill me with poison."

She wanted to speak but I quickly cut her off. "Did you really think I would fall for it, Ume? I've been alive for centuries. I've had countless people close to me try and kill me, some have even chopped my head off. But tell me, why do you side with this monster?"

"He's given me everything I never had."

It was so quiet that I could hear the heavy breathing of a man two rooms down in a courtesan room.

"So you would kill me in his place?" I chuckled a bit and poured myself some more tea. "You know, for tea that was poisoned, it's quite delicious. Fatal to us demons but a delicacy to humans. Tell me, have you enjoyed your time as a demon knowing you are the reason why I created the Demon Slaying Corp?"
