"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'.
