A cool breeze brushed through the streets of Tokyo, gently passing through the city and giving the citizens some relief. A cool night breeze was always appreciated in summer.
The streets were bustling with activity, filled with people going on and about their business, they were lively and energetic as if the time of day was not night, the lights were bright, shining brilliantly and showing everyone the wonders of electricity.
An expansive, sleek black car, modelled similarly to a limousine with heavily tinted windows, travelled through the road, the driver paying careful attention not to hit any drunkards in the road.
While it was late at night it wasn't so late that the streets would be empty, in fact the sun had only set a mere two hours ago so the street being busy was understandable.
The driver of the car was a man with light pink hair and skin so pale it was almost like a sheet of paper, the man had tattoos on his face that at first glance one would liken them to the lines of a basketball.
The drive was relaxing for him plus, it offered him a good way to be useful to the master without having to be the one he directs his ire towards when mad.
At the back of the car, in the passenger area, there sat two people, a handsome man with blood red eyes, short black hair and incredibly pale skin. He wore a three piece suit and held a glass of red wine in his hand.
"Ume, please understand"
His voice was deep but he spoke with a soft affection, gently reverberating through the air and reaching the ears of his companion, his blood red eyes changed to look more human and he placed the glass of wine to the side
The woman he was talking to, Ume. She was a woman that radiated an indescribable beauty, her eyes a vibrant hue of deep blue and her skin pale but retaining some blush on her cheeks, she had illustrious black hair flowing down her shoulders and back.
Her lips painted, luscious and kissable, painted with an eye-catching red lipstick. They were ones that made men believe it was an honour to receive a kiss from such attractive lips.
"Understand what? Muzan-sama"
She addressed, her tone respectful but her face conveyed her anger well, her brows furrowed deep and her head cocked to the side, a habit of hers that Muzan was used to by now, it was certainly unsettling but he knew it well.
"You know I don't like it when you address me like that"
He said and she stared at him unblinking, refusing to acknowledge his words.
"You know, I have to visit her, you understood this years ago, why is it a problem now?'
"It's not a problem, Muzan-Sama, you can do whatever you like. Disregard my opinion completely"
She said her voice betraying her emotions and her lips curving into a smile but her brow still creased in anger, Muzan sighed in slight annoyance and tiredness, she was definitely difficult to argue with when angry.
When he got reincarnated as Muzan Kibutsuji in the 1950s he definitely didn't think he'd be having such problems, it's a good thing he only got two wives, a harem of them would be a different level of splitting headache.
"Then, What is the issue?"
He asked, it would be exhausting to go back and forth with her on this, but he would prefer it if she wasn't angry when he exited the car. Meeting your wife while your other wife is mad at you was not ideal.
"The issue is, you were going to see her but you were not going to tell me, as your legal wife am I not entitled to know your whereabouts?"
She asked. She placed great emphasis on the word legal, her anger rising as her brows furrowed deeper, she did not believe she was being unreasonable and that what she was asking was something that was a given.
"Ume, I shouldn't have to tell you when I'm visiting her, she's my wife as well."
"Wife, in name only, I am your legal wife and I'm not saying you shouldn't visit her, I'm saying I'm entitled to know when you are"
She explained and Muzan simply let out another tired sigh, she was definitely a handful. The conversation will go nowhere because he doesn't believe he's wrong and she doesn't believe she is wrong, and thus they were at a stalemate.
"Come here"
He beckoned and stretched out his hand, her body lurched forward slightly before she quickly pulled herself back, maintaining her angry expression.
"No"
She denied and he simply shook his head in amusement, it was always cute when she denied herself the thing she wanted the most.
Instead of her coming to him, he went to her and sat next to her, snaking his arm around her waist and pulling her head to rest on his shoulder, and much like a magic her angry face vanished, revealing the soft love stricken face of a maiden.
"You know I don't love her anymore than I love you right"
She weakly nodded at his words, grabbing onto his clothes and clinging to him, he smiled at her antics of trying to keep him in place.
He used his hand and gently forced her to look at him before giving her a chaste kiss on her cherry red lips.
"I won't be gone for long, and even if I am, you can hire someone to monitor me"
He advised, he had long accepted her Yandere-like behaviour, although she wasn't deep into being a Yandere that she wanted to kill any and all women he spoke to.
"okay"
She weakly agreed and he gave her another kiss, this time it was deeper and more intimate. Their tongues danced together as they shared fluids before separating but she quickly buried her face into his chest as she tightened her grip on his suit.
The car had stopped and it was time for him to exit and it seemed she didn't want him to go. Part of him liked that she wanted him so much but at the same time it was annoying.
"Ume my dear, this was an expansive suit and you have very beautiful but sharp nails"
He said but she still held him, it took a full minute before her grip let up and he finally was able open the door, gave her a goodbye kiss and exited leaving her to exhale deep sigh and pout.
...
A/N: in case it isn't clear Muzan is a reincarnator but that won't really help him much and won't be relevant most of the time. The reason is because I don't like evil protagonists and making him a reincarnator seemed like the easy way to change his character without too much backlash from you guys.
Another thing, the breathing techniques won't be breathing techniques but instead actual powers and I'll try to make each of them unique and offer the slayers different physical advantages.
Like the stone hashira being more durable etc.
Also the demon slayers won't be that many in numbers and Muzan won't be the only one who can turn people into demons.
I have other things to say but this getting a bit long, so I'll just reveal them as the story progresses.
