Ever since that day you fought the oh-so-called Hashiras, most of the demon slayers were afraid of approaching you. To say the truth, you were glad that you made yourself known to be the most fearsome person that ever existed. The only thing you regret was why didn't you meet this demon lord before you get sealed? He and his minions can just fight the sorcerers with you, but oh well.

What's in the past remains in the past.

Right now, you were resting in your room. Uraume managed to find you a house in the depths of the forest, a good place to rest after a long day of killing, right? You decided to get some sleep, but you were surprised when you found yourself in your innate domain and this time with your actual and real form. You were both happy and frustrated. You can return to your original form, but only in your innate domain. Annoying right?

But that's not the problem.

The thing is when someone enters your room, they actually enter your domain because of the overwhelming cursed energy. It makes whomever steps in to lose consciousness and their soul to wander into your mind. Uraume has tested it herself and she made sure to stay out when you sleep and prevent anyone from coming near your room, plus she stopped the demon lord one night from enter your house even. He can't kill her and get in because you warned him that if Uraume was killed by him or any demon, he will see a very dark side of you that nobody has seen.

One night, Muzan watched from the shadows as Uraume was patrolling around the house. He didn't know for how long has he been waiting for her to leave and he was getting frustrated, but suddenly she started to run as if she was chasing after something and this was a great opportunity for him to get in.

He didn't know that Uraume went chasing after a special-grade curse that was trying to sneak in.

The red eyed man casually walked into the house and started to search for your room. It didn't take long for him to find your room since there wasn't much rooms in the house. Once he put his hand in the shoji door, he felt a great pull as if his soul was being ripped out of his body. Suddenly, everything changed. He found himself a whole different place. There was blood red water underneath his feet and a huge ribcage above him, but what caught his attention was the pile of skulls that formed a mountain and above it was you sitting like the queen you're.

[Just imagine Sukuna's original appearance of four arms and two faces.]

"Well, what an unexpected visit."

Muzan squinted his eyes, trying to get better look. However, the shadows covered your upper half. "Where am I, Y/N?" He asked you while moving his eyes around the place.

You smirked and extended one arm out, "This is my Innate Domain aka my mind." You stood up and jumped from your throne in front of him and this time he got to see you more clearly, "Why is she different?" He thought as you approached him slowly. You had four arms and two faces, the marks on your face were lesser than before. You were also pretty tall, taller than Muzan himself as you appeared to be a bit muscular. The black undercut was gone and your hair was fully pink.

You smirked as you looked down at him, "Like what you see, Muzan sama?" You uttered with a hint of mockery. Muzan kept his blank look, but deep down he was freaking out. Even though he has different forms, this is the first he sees something that screams fearsome and evil like this.

Muzan shook his head to snap out of his thoughts, "What happened to you? You look a lot different." He asked you, looking up at you to see your face. You hummed and crossed two of your arms in your kimono while the other two lied limp by your side, "This is my real appearance, what I used to be." You explained as you looked to the side. Muzan hummed then started to walk toward your throne, "I heard that you fought the Hashiras alone."

"Ah, yes I did. They're not as strong as you said they are. I didn't take a lot to beat the hell out of them." You said followed by an evil laugh.

"Why didn't you kill them?"

"Hm? I just wanted to waste time on them, also why kill someone that might be useful in the future."

Muzan turned around and raised an eyebrow at you questioningly, "What do you mean?" You rolled your eyes at his obliviousness to the best option to disband the Demon Slayer Corps, "Why don't you use the Hashiras and turn them to demons. Like that guy with six eyes." You suggested and Muzan gave it a thought, "This could probably be useful." You sighed and appeared beside him, grabbing his hand and jumped up to your throne. You made some space to him so he can set beside you.

After you finished, you sat down cross legged and looked at his puzzled face, "Sit." You ordered and he just sighed, sitting down beside you. You both went silent as you just sat there with your your cheek on your hand. Your eyes were focused ahead while Muzan felt kind of awkward because of the silence.

"This place is kind of strange, I have never seen something like this before." Muzan spoke up, breaking the silence. You glanced at him from the corner of your eyes, "Indeed. I remain here when I can't take control of that kozo I call my vessel."

"I see."

Then it went silent again. However, Muzan noticed that he was getting sleepy as the minutes passed and was wondering why though, "You're leaving my domain, I'm waking up." You said as you pulled him to lean on your shoulder, it didn't take long for the darkness to consume his mind.

"Oi, wake up sleepy head."

Muzan opened his eyes and saw you staring down at him. He sat up and found himself sitting on a futon and covered with blankets. He looked at you and saw you back to your normal appearance, "You're back to normal."

"Yeah, it's only when I'm in my Innate Domain. You slept longer than expected, I normally kill the person to get them out of my domain, but you're a special case."

Muzan nodded and was about to stand up, but you grabbed his wrist, "Where do you think yourself going?" You asked as you raised an eyebrow at him.

"To my work."

"It's already morning, so you will stay here for now. Plus I'm bored and need some company."

The black haired male didn't say anything and just sighed, nodding after that. The whole day, you both knew each other more and more. You found him really interesting, but he was hiding something and you will know it sooner or later.
