Kibutsuji Muzan is simply reading a book in his office when a powerful presence suddenly makes its presence known to him.
"So you are the King of Demons," an accented voice remarks and Muzan instantly becomes on guard and looks up to see who has managed to sneak up on him.
His gaze is met with the sight of a beautiful red-headed woman sitting on the chair across from him.
"Who are you?! And how are you able to enter my domain without me noticing?" He demands as he stands from his chair to tower over the petite woman, who remains stoic in the face of his mounting wrath.
"My name is not important, Kibutsuji-san. All you need to know is that I am not your enemy... So…what does the King of Demons do in his spare time?" the woman asks him curiously.
Muzan stares at the strange woman for a moment. He remains wary of her because he can sense the immense power emanating from her figure. He knows that she is not to be trifled with. He also knows deep down that she is more powerful than him. So he tries to appear calm and sits back in his chair like he hasn't just jumped to his feet not a moment ago.
"What is it to you with what I do during my spare time?" he inquires, his eyes narrowing suspiciously at her.
"Because I am bored…and it's because I find this world interesting enough to take a vacation here," is the woman's response.
This world? Does it mean that she is not from around here? He thinks with a frown.
"You are on a vacation here? Then, why the hell are you bothering me?! There's plenty of beautiful places to visit in this world," he points out, sounding annoyed.
Muzan watches as a breathtaking smile suddenly stretches on the woman's lips.
He can tell that his answer has amused the powerful woman.
"I am bothering you right now because I find you fascinating, Demon King.." the woman admits to him without preamble.
Kibutsuji Muzan can almost feel his brain cells faltering at the way the woman smiles at him and hears her admission in that moment.
Me? Interesting? He wonders, looking somewhat bewildered and utterly bewitched.
"Woman, I – I don't even know you…" He sputters.
He sounds flustered.
In fact, he is.
He has never been taken off guard by someone before and now this presumptuous woman has just barreled right through his carefully erected barriers without hesitation.
"Well, why don't I rectify that then," The woman replies, still smiling that earth shattering smile. "My name is Harriet Potter…and I have decided that you will be my tour guide from now on."
He can almost hear the 'Or else' there in her words.
Muzan can only gape at her speechlessly.
Me? A tour guide?! Is she insane?! He can only wonder silently.
"I'm really busy. So I don't have any time to cater to your whims, Harriet-san," He tells her bluntly while he glares at her.
"I am sure you will find time for me, Muzan-san," She says to him sweetly, still smiling that mind altering smile. "Especially after I'm done with you."
Muzan suddenly feels a chill go down his spine at the woman's threat.
"Are you threatening me, woman?!" He hisses while he stands up from his chair and bears his fangs at her.
Then, without warning and with less than a blink of an eye, the woman is suddenly in his space and touching his fang with her dainty finger.
"How cute!" The woman exclaims as she runs her finger underneath one of his fangs where it accidentally pricks it.
A drop of blood suddenly enters Muzan's mouth and he instantly becomes lightheaded at the taste of her blood in his tongue.
There is a strange power surging through him the moment he ingested the woman's blood. He feels like he is drugged and intoxicated at the same time that he can't help but sway in his feet and look completely dazed.
"Ooops!" the woman says as she withdraws her hand swiftly. "My bad! I didn't mean to bleed on you!"
Muzan's only reply is to look at her with a befuddled expression while still trying to process what just happened.
"So what do you think about you being my tour guide?" the woman – Harriet – asks him after a moment.
"Where do I un-sign to be your tour guide?" He growls at her.
At his question, the woman simply laughs at his face and answers, "By the end of the day, it will be voluntary."
Afterward, she grabs his arm and then they disappear from the office altogether.
Muzan soon realizes that he has just been abducted by a strange woman without a fight.
