After finishing a round of sex, Daki and Kensuke laid next to each other in her room, hugging each other to keep warm as a cold wind blew outside. The two took a nap for about an hour before the force of the wind caused a window in a neighboring room to force itself open, waking Daki up. "Hmmmm…" She stirred awake and sat up from the floor mattress, realizing that she had to tell Kensuke that today would be their last day together. "No… I don't want to do this, but…" She took a deep breath and shook him awake. "Hey, Kensuke, wake up."

"Huh?"

As Kensuke sat up, Daki told him, "There's something I need to tell you."

Based on her tone, Kensuke knew it was serious. "Daki, what's wrong?"

"It's about us…" Daki could feel her heart shattering as she began to deliver the news to him with a heavy sigh. "Kensuke, I… I love you, but I can't be with you anymore."

Confused, he asked her, "Is… Is this a joke?"

"No," she replied with a solemn tone as she shook her head. "I wanted us to last longer, but…"

Kensuke could not believe what he was hearing. "This has to be a nightmare. No… No, you can't leave me. What the fuck…"

Daki then got up and began to get dressed. "Please, leave the room. I'm sorry, Kensuke, but circumstances beyond my control prevent me from being with you."

"Leave… Why?"

"I didn't want to do this to you," Daki said as she turned away from him. "But I'm a demon, and… I can't do this anymore. I don't want to put you in harm's way. If you stay with me, you'll only put yourself in danger."

Kensuke hugged Daki from behind as he began to cry. "Please, don't do this to me. I love you, Daki. I really do love you… Why the fuck is this happening to us… Why?"

Daki gently took his hands off of her. "I love you, too, and that's why I'm leaving you. I love you too much to put you in real danger."

Kensuke began to sob as a wave of emotional pain overcame him and he sank to the floor. "Why… Why do I always end up alone?! Why?!"

Daki turned around and looked at him, doing her best not to cry as well as she then turned back and finished getting dressed. "Please, let me be at peace for tonight. I still have work to do."

Kensuke, still crying, began to get dressed as well, and once he was finished, he walked out of the room. Before he left, he wiped his eyes and nose before telling her, "I'm never coming back here, and you'll never see me again. I quit."

Before Daki had a chance to react, Kensuke slammed the door shut. Daki yelled out, "Wait, no! You don't have to quit!" It was too late, however. Daki could hear him walk down the hallway and down the stairs, presumably to turn in anything that was given to him by the brothel and leave. With him now gone, Daki crumpled to the floor and sobbed rather loudly, having done what Muzan had asked of her at the cost of her emotional and mental well-being. "Why…"

One of the other girls ran into the room upon hearing Daki sob, deeply concerned for her. "Shiraume-oiran, what happened?!"

"I…" Daki then looked up at the girl, tears still streaming down her eyes as she tried to find the words to explain what had happened through her cries. "Me and Kensuke… We… We broke up…"

"Oh my God… Shiraume-oiran, I… I'm so sorry…" The girl hugged and comforted Daki, who was too overcome with grief to care that a supposedly 'lesser' human was touching her as she returned the hug. "It'll be okay… We're here for you, okay?"

"Fuck… Why… God damn it…"

Daki went through the motions as a customer finished having sex with her, still depressed over having to leave Kensuke. True to his word, he had walked away from the brothel and never returned, much to the dismay of the other girls and especially Kaori. As the customer fixed his clothes, he asked her, "Hey, you didn't seem too much into it. What are you, a dead fish in bed?" Daki ignored the man, causing him to sneer, "Whatever. At least I got what I wanted, a nice fucking. I thought you needed a good hard fuck to do something, but I guess not even that will help."

When the man left, Daki was now all alone in the room, allowing her thoughts to stew inside her head. Ever since Kensuke had left, she had felt a growing resentment towards Muzan, but knew that she would be killed almost immediately if she tried anything. Frustrated with the inability to do anything to make herself feel better, she smashed a small vase in her room and yelled in a blind rage, "God fucking damn it, I hate this shit! Fuck you! Fuck me! Fuck all of this! Fuck everyone! Fuck it all! God damn it, I hate my life! I hate everything! This whole fucking thing is gonna kill me, and I can't do a fucking thing about it! What the fuck is wrong with my world?! Why the fuck can't I get through this?! Why the fuck do I have to deny myself happiness?!" Then, she picked up a handheld mirror and threw it against the wall, smashing the glass to pieces. "Why the fuck should I even give a shit about anything anymore? I hate this fucking place so much!"

As Daki took several deep breaths, Gyutaro jumped out of Daki's body and looked around to find the room a mess. "Holy fuck… This room's a mess… What did you do?"

"I needed to vent," Daki replied to him.

Gyutaro asked her, "Well, how do you feel now?"

"I broke up with someone who I thought I could finally settle down with, the breakup is affecting my work performance, and that same boy quit and left us without a competent bodyguard… How the fuck do you think I feel, oniichan?"

"You need to calm down, man," Gyutaro warned her. "If you don't, our master could punish you."

"And what if he does, huh?!"

Shocked that Daki would speak in such a way about Muzan, Gyutaro cautioned her both in anger and out of worry, "Do you have any fucking clue what you're saying?! If you keep this up, he could very well kill you! The last thing I want is my sister dying and me not being able to do a God damn thing about it!"

"So fucking what?! My life is over as far as I'm concerned!"

"Don't you fucking dare think that shit!"

"You can't tell me what to think and what not to think!"

Both of them then heard a billowing voice in their heads, forcing them down to their knees in pain. "ENOUGH!" The voice clearly belonged to a very angry and annoyed Muzan, who soon after caused Daki to disappear from the room and appear in an alleyway nearby instead.

As she opened her eyes and looked around, Daki asked herself, "Wait… Where the Hell am I?"

Muzan commanded her from down the alleyway in a loud voice, "QUIET!"

In fear, Daki bowed down before Muzan, her rage against him now suppressed by the overwhelming dread she felt. "Yes, Muzan-sama…"

"It seems that merely breaking things off with that human boy wasn't enough," Muzan told her as he walked forward. "You've been nothing but a whiny bitch for the past five days, and I'm sick and tired of it, so I'm gonna make a fucking ruling on this right now: I'll take care of it, and you will forget this ever fucking happened."

Daki thought in her head, "I'll forget? What does he mean by that?"

"I want you to take a good look at what I've brought for you," Muzan said as he stepped aside and let another demon who had accompanied him drag a body forward for Daki to see. "Thank you. Now, return to the fortress and await further orders."

"Yes, Muzan-sama," said the regular common demon before Muzan sent him away with the snap of his fingers.

"Take a good hard look at this," Muzan ordered Daki as he held up the body by the back of its shirt.

"Wait… What…"

"Daki… Help me…"

The body was in fact Kensuke, who had been badly beaten and was barely alive. Numerous bruises covered his body and face, and he bled profusely from his nose as well as an empty eye socket. Daki gasped in horror as she said, "No… No, you couldn't have…"

"This is what you get for your disloyalty!"

Muzan then kicked Kensuke in the side, causing him to yell in pain, "Agh, fuck!"

"No, please, stop!" Daki, in desperation, offered, "Please, let him go! He didn't do anything wrong, Muzan-sama! I'll sacrifice my own life if it means you'll keep him alive!"

Kensuke looked over at Daki and said, "Wait… What?"

Daki declared as loudly as she could as tears flowed down her eyes, "Kensuke, I love you! I didn't want to break up with you at all! That man forced me to! I'll always love you! I swear!"

"You… You really meant that?"

"Yes! Every word!"

Muzan coldly told her, "Not a chance. You're far too valuable to me. Why should I kill one of my Upper Moons right now when I can kill this human and enjoy a nice meal?"

"No! Don't do it! Don't take him from me! Don't kill him!"

Muzan coldly ignored Daki as he stabbed a young man around the same age as Zenitsu with his hand while the three of them were in a back alleyway, cutting right through his chest and ripping his heart out. As he stared at his own heart being shown to him, he then passed out and died in a matter of seconds from blood loss. "There we go," Muzan said to himself as he then removed the heart via the entrance wound he made and ate it in front of Daki.

As he chowed down on the heart he had just taken, Daki wept. "No… No, God, no… Kensuke, why…? What the fuck… No!"

Annoyed with her crying, Muzan glared at her after finishing the human heart and ordered her, "Stop your whining and go to sleep!"

"Fuck you, you can't make m-" In an instant, Daki passed out in front of him, lying motionlessly on the ground. As she lay still, she thought to herself as tears still flowed out of her eyes, albeit at a slower pace, "Kensuke… No… I can't fight back… I'm sorry."

Within moments, Doma arrived to take Daki away to be wiped of her memories of Kensuke, and the scene was soon cleaned up, with not a trace of the young man left at all in the alleyway. As far as anyone else was aware, it was as if the boy never existed.

January 27, 1884

"So her memories are fixed now?"

"Correct," Muzan said to Gyutaro in a room within the Dimensional Infinity Fortress as they both looked at an unconscious Daki, who had been laid out on an operating table. "She'll be just like she was before she met that pathetic human. If you tell her anything about this, well… There will be consequences."

"What kind of consequences?"

"Lethal," Muzan sternly warned him. "So don't fucking do it."

"I see…" Gyutaro felt bad for what her sister had been through, but knew he could not do anything about it. "With this done to her, it'll be like nothing ever happened. We'll have to go to a brand new brothel since there's not a chance in Hell we can go back to the old one. I'll have to come up with a new oiran name for her."

"Hmmmm…" Muzan then came up with a name. "Would Yatamahime work?"

"Maybe… I'll definitely keep that in the back of my mind." Gyutaro himself usually never came up with new names, but in this case, he would have to in order to expedite the process. "It doesn't sound too bad, actually."

"Before you go with her back to Yoshiwara," Muzan then told Gyutaro. "There's a demon that I want you two to help mentor. I think she has potential to be one of the Twelve Demon Moons, as long as she's set on the right path."

"A demon to mentor, huh?"

"Her name is Mukago," Muzan explained. "She was a lower-ranked prostitute before she was demonized, so perhaps your sister and her can bond over that."

"I'll consider it," Gyutaro replied with a shrug.

"Give me an answer within a week."

"Yes, Muzan-sama."

As Muzan left the room, Daki woke up and turned to see her brother. "Hey…" She rubbed her head, experiencing a slight headache from the procedure. "Agh, shit… My head hurts…" Curious as to what happened, she asked her brother, "Hey, what's going on?"

"We gotta go to a new brothel, Daki."

"We do? Why?"

"Security reasons," he explained. "Me and Muzan-sama even came up with a name for you to use."

"A name?" Daki chuckled as she sat up, having completely forgotten about Kensuke. "What kind of name? If it sucks, I'm gonna reject it."

"Yatamahime."

"Yatamahime, huh?" Daki nodded. "I guess I could make it work."

"Sounds good to me. By the way, Muzan has a demon that he wants us to mentor."

Daki, curious, asked her brother, "A demon to mentor? Who and why?"

"Her name is Mukago I guess. She was a lower-ranked prostitute before she got demonized, and Muzan thinks she could become one of us."

"One of the Twelve Demon Moons?"

"Yep."

"Hah… We'll see about that." Daki then walked out of the room. "Let's head back to Yoshiwara and get this whole new brothel shit settled before we even discuss mentoring someone."

"Agreed." As the two of them walked down the hallway together, Gyutaro thought to himself, "Well, that was an interesting way to end our time at that brothel. It was certainly one of the most explosive endings to our time at one… And one of the most painful. I still can't believe they were able to clear all of her memories of Kensuke away."

…

Of course, thirty years later, those same memories would in fact come back with a vengeance, allowing Daki to finally recall her love for Kensuke in her final moments.

Upon Daki passing into the afterlife, she had returned to her form as a human right before she was demonized. She walked in a black void, aimlessly wandering for quite some time as she tried to find somewhere, anywhere to go. She called out in a state of panic, "Hey! Hello?! Is anyone out there?! Hello?!"

"Daki!"

"Huh?!" Daki turned around and saw Kensuke standing before her, her panic giving away to joy as she ran up to him and gave him a hug. "Kensuke! Kensuke!"

"Daki!"

The two embraced and spun around as they were reunited in death. As Kensuke set her down, he told her, "Even in this form, I could never not recognize you."

"Yeah, I do look pretty different." Daki then told him, "In my final moments, I finally remembered you."

"I know…" The two then shared a long and passionate kiss, the first they had shared in thirty years. As they continued to express their love for each other, Daki thought to herself, "He was waiting for me the entire time… He refused to move on until I joined him, no matter how long it took…"

As the two split, they heard a voice call out from behind them. "Ume! Kensuke!" Both of them turned around to find Gyutaro running towards them. "Hey! Over here, man!"

"Oniichan!" Daki then ran up to him and gave him a hug as well.

Gyutaro told her, "Ume, listen, there's something I have to tell you."

"What is it?"

"Look, you… You still have a chance to go to Heaven." Gyutaro then sighed and split from her. "I don't. I can't go to Heaven with you. I'm going to Hell."

"Wait… What?"

"Be with the love of your life," Gyutaro instructed her. "Don't come with me. You don't deserve it. You deserve Heaven with Kensuke, Ume."

Kensuke replied to him, "You… You can't be serious, right?"

"No," Daki rejected Gyutaro. "I refuse."

Surprised, Gyutaro replied, "What?"

"I won't abandon you, even if it means I have to come to Hell, too."

"But…"

"Count me in, too," Kensuke added. "If it means I can be with Daki, or as I should say, Ume… I'll go to Hell, too."

Gyutaro replied to both of them, "You guys don't have to…"

Kensuke then kissed Daki again before telling her, "You are worth Hell, my love." The two then held hands and walked towards a growing fire that was some distance away, a fire that all of them recognized as the entrance to Hell.

"Come on," Daki told Gyutaro, extending her other hand.

"Fuck it," Gyutaro then said as he ran over and took Daki's other hand. With all three of them together, they all walked towards the fires of Hell, determined to support each other no matter what lay ahead for them. "You look just like you did before that mob burned you, Ume."

"I know, right?"

Kensuke remarked to her, "You look absolutely beautiful, Daki."

Daki smiled and replied, "Thank you, Kensuke."

With that, the tale of Daki, Gyutaro, and Kensuke that had begun so long ago finally came to a bittersweet end.
