"Time to get moving. Can't let a certain demon doctor wait for too long now, can I?"
Muzan said to himself with a playful tone in his voice.
He then used Biokinesis to shapeshift into a different form.
Now, he had long black hair, plum red eyes, a height of 5'3", and a surprisingly big bust. His new beauty was breathtaking, the kind that would make any woman jealous.
Yes, he had transformed into a woman. He was planning to play the victim card as it was his best strategy to get closer to Tamayo. Or he could simply break in after subduing Yushiro, given Tamayo is not that powerful.
But first, he had to deal with that nuisance, Yushiro. Yushiro's Blood Demon Art was extremely troublesome, and he wasn't under his (Muzan) control. Letting such a powerful demon roam freely was out of the question.
Yushiro's Blood Demon Art had been one of the reasons for Muzan's downfall in the Infinity Castle Arc. Nakime, with her blood demon art abilities, was his priceless subordinate. He wouldn't let anyone else control her.
"I wouldn't let anyone control my precious Nakime, no one. She is mine." Said Muzan with a hint of possessiveness in his tone.
He made his way to the balcony and pushed open the windows. With his supernatural senses, he took in the distant view of Asakusa, a district nestled within Tokyo, the capital of Japan.
"But first I have to take care of Tamayo. "
"I will make you watch as I fuck her in front of you, Yushiro. Be a good cuck and enjoy the feast of NTR before your death. Hehehe." The thought excited him.
He snapped out of his monologue when a knock sounded at the door.
"Hmm?"
"Toshikuni? My child, are you alright? What was that noise, dear? Are you alright?" A mature feminine voice was heard, laced with worry.
"Should I just kill her? I haven't consumed anyone for a decade," Muzan muttered to himself. Suddenly, all seven of his hearts started to beat faster, making him more aware of what he had just said.
He felt like he was about to do something he would never wish to do.
"Damn you, Makkari... You've made me weak. Me, caring for humans? What a joke," he said, placing a hand on his chest.
"Let's just ignore her. They took care of me for 13 years; it's the least I could do.
"Goodbye, 'Mother'" With that, Muzan took off from the balcony with such speed that a portion of the room was wrecked.
***
In Asakusa, within a secluded room of the house, cloaked from the outside world by mystical talismans draped over its compound, a beautiful woman with long dark hair tied up with floral tama-kanzashi hairpin, dark purple eyes, and blood-red lips, sat gracefully in seiza.
She was none other than Tamayo, the demon doctor who hated Muzan with a passion.
Today was a sad day for Tamayo. Today was the nth death anniversary of her husband and child.
It was dreadful day of the year which reminded her of the biggest tragedy of her life. And as a demon, she was cursed to live eternity with this guilt.
She killed off her family and many innocent people because of her rampage. She hated it.
Every action she committed after being turned into a demon…she hated every second of it and it was all his fault.
Reminiscing the tragic day is what she did the whole day.
KNOCK KNOCK
She was jolted back to reality by the sound of a knock on her door.
"Come in, Yushiro."
With those words, the door creaked open. A young man of short stature and average build, with pale skin and striking lavender eyes stepped inside the room.
He bowed and then walked towards Tamayo. Kneeling, he gently wiped her tears away with his hand.
"Your tears do not suit you, my lady. Please, allow me to help you in any way possible."
"It's alright Yushiro. I-"
"Nothing is alright if you keep thinking of that incident the whole day. You have to focus on how we can take revenge on Muzan!" Yushiro said with frustration as his hands were firmly on Tamayo's shoulders.
'Oh, how I wish to savor those lips and let you know about my feelings my Tamayo.' Yushiro thought as his heart beat faster. He then gave a helpless sigh.
"Tanjiro and Nezuko are already working hard, it's time we focus on perfecting that drug," Yushiro said with a calm tone.
Tamayo widened her eyes and soon a smile crept on her beautiful face.
She looked like a goddess with that smile. Though Yushiro.
"You're right. I promised to turn Nezuko back into a human. I can't let Tanjiro down. He's our last hope against Muzan."
"Lady Tamayo, there is something I have been meaning to tell-"
STAB
Before Yushiro could finish, his heart was stabbed and then blood splattered all over Tamayo.
Tamayo widened her eyes in horror as she made eye contact with 'her'.
"Impossible!"
"My my, you have grown more beautiful than the last time I saw you, my dear…Tamayo~" Muzan said with lots of 'love' and 'passion'.
***
"Yushiro…" Tamayo said in a broken tone. She could not believe her eyes.
How was he able to infiltrate their hideout? Shouldn't Yushiro's demon art counter his extrasensory perception?
"Muzan Kibutsuji…how fucking dare you!!" Tamayo said with pure malice. Her tone was full of hatred.
She gritted her teeth and slowly her facial characteristics took on more demonic traits.
She decided to use her strongest technique to buy some time. She was smart enough to know that she didn't stand a chance in front of him.
And what's worse is that he had incapacitated Yushiro so she also had to be wary of his demon art now.
She raised her left hand, making a hand sign "Scent of Destructive Dream, Eternal-"
But she couldn't finish casting her technique as her left hand was literally ripped apart from her body by him.
"Did you think I would let you finish casting your technique? Tch, no wonder villains have a bad reputation." Muzan said with a hint of frustration in his tone.
He then brought his attention to Yushiro who was about to regenerate his destroyed heart.
He held Yushiro by his neck and lifted him off the ground.
"Now be a good dog and watch as I break your lover."
THUD
Yushiro was thrown against the nearby wall with such force that it caused his limbs to break apart, and even cause his neck to take considerable damage.
The peculiar thing was, that Yushiro was not regenerating back.
Muzan removed the talisman from his chest, waving it in the air to show Tamayo.
Looking at the talisman in Muzan's hand, Tamayo widened her eyes in shock.
"H-how? How can you u-use that?"
Muzan had a sly smile upon seeing her reaction.
"There's nothing my blood cannot influence. Just a drop on the talisman that hide this place, and then I bent its magic to mask my presence. Quite the amusing little trick, wouldn't you say?" Muzan said while boosting himself as if he were the sin of pride.
"Now…What will happen to you, Tamayo? Hahahahahaha" Muzan laughed like a maniac. He absolutely loved this situation where his enemy was vulnerable and unable to strike back.
He transformed back into his male form, and then knelt in front of Tamayo and cupped her cheeks.
"It was way easier to come in contact with you than I thought. Heh"
Why did Muzan transform into a woman in the first place? Well, he was going to pretend to be a newly turned demon who killed off her 'family' out of rampage.
And since Tamayo's clinic was near, she would notice and decide to come to her to prevent him from causing more rampage.
And when Tamayo was near him, he would strike back.
But there was a flaw in this plan. There was no guarantee Tamayo or Yushiro would come to his aid.
For he thought, demon slayers would come to slay him which would jeopardize his plan.
Also, this was very time-consuming and time was the thing he didn't have right now.
So he decided to do a little experiment. He recalled the location where Susamaru accidentally activated the curse when she said his last name.
All the demons cursed by him, he could sense their location as well as memories if they were in his line of sight.
So retracing Susamaru's footsteps and finding the clinic was a piece of cake. As he reached the clinic, the rest was history.
He wondered why the old Muzan never found Tamayo all these years.
Well given the old Muzan's cowardice tendencies, it all made sense.
'Tch, what a coward.' Thought Muzan.
Coming to the present, he looked at Tamayo who stared back at him with such a gaze that if looks could kill you, he had be dead thousands of times.
"Tell me, Tamayo, how many times will you keep running away from me? You know I can't live without you~"
"Lies. You only see us as your pawns. You don't care about other people's lives before turning them into demons. I-I lost everything, all because of YOU." Tamayo said with an outburst.
She was about to die. There was nothing she could do.
She hoped Tanjiro would avenge her.
"Even if you take me with you and put that curse on me again, I will activate it and kill myself. I will never listen to you." Tamayo said as her emotions overpowered her rationality.
"Oh my. I never wanted you to hate me, my dear…I wish I could fix things between us. Sigh. It was my oversight to leave you after just transforming you…" Muzan said as he moved his hand through her smooth hair and removed her hairpin.
"..and you look more beautiful with long hair." Muzan was half serious, he knew smooth talking was not going to melt the heart of this ice queen who harbored a deep hatred for him for many centuries.
Tamayo just looked a bit surprised but she still hated him.
She didn't say anything and stayed silent. She already accepted her fate, and even if she decided to kill herself, he wouldn't let her and she knew this very well.
"You're an invaluable ally to me, Tamayo. I should have looked after you more. Well if this doesn't change things between us then I have no choice…but to brainwash you." Muzan said as he finally revealed his real intention.
Tamayo's expression turned horrified, she didn't know he could manipulate memories as well. This was something she never accounted for.
Before she could say anything, her heart was stabbed by Muzan's hand which was morphed into whip-like appendages. He then poured a small portion of his blood into her body.
While all this was happening, Yushiro just watched this despairing event unfold in front of his eyes.
He was too weak to move or speak. Hell, he couldn't even move since he cannot regenerate his limbs for some reason.
He was having an internal breakdown as he looked at the love of his life being taken away by that demon.
He could do nothing but pray that Tanjiro would avenge Tamayo.
Meanwhile, Tamayo coughed blood as her heart was stabbed. Her eyes lost the vitality they had as if she was dead.
A minute later, she regained consciousness and then looked at the man in front of her in confusion.
He was very beautiful, and his white hair and plum-red eyes made her even more attracted to him.
"W-who are you?" Tamayo asked with a timid tone.
Muzan couldn't help but smile.
'It seems my plan worked. Now all I need to do is to make her believe me and then she will be mine.' Thought Muzan as he secretly heaved a sigh of relief.
"Did you forget about me? My love Tamayo? It pains me to know that you no longer remember your lover anymore." Muzan said with a 'sad' tone.
"L-lovers?" Tamayo asked in a tone of surprise.
"Yes, my love. I turned you into a demon a long time ago so we could spend eternity together. But during my fight with a strong demon slayer, you tried to save me but ended up losing your memories. I-I thought I would never find you…" Muzan said with 'desperation' in his tone.
Listening to his explanation, Tamayo felt like she was on a roller coaster of emotions.
"If you wish to trust me and come with me then hold my hand, Tamayo. I might not be able to see you again if you decide to reject me." Muzan said as he offered his hand to Tamayo.
Looking at his beautiful yet gentle eyes, Tamayo finally made up her made and held his hand firmly.
"I hope you are not lying to me…"
"Muzan. Muzan Kibutsuji is my name. Always remember that." Muzan said with a massive grin creeping on his face.
As soon as Tamayo took his hand, he pulled her into a hug and then kissed her lips passionately.
Tamayo was taken aback by his sudden boldness but did not object. She hugged him back and returned the kiss. Slowly their kiss deepened and sounds of sloppy kiss spread throughout the room as they intertwined their tongue in a lewd exchange.
Muzan then pinned her against the wall and started making out with her. He removed her kimono and gently undressed her.
All this happened while poor Yushiro watched them with tears of blood coming out of his eyes.
