"What's this?"

"What's going on?"

Questions after questions left the mouths of those in the crows as they watched the spectacle happening in front of them. "Stop it!" Tanjiro shouted as he binded his fist with a cloth and went barging towards the man, placing his leather-covered hand to the mouth of the recently turned demon.

You were left aghast, self unknowning as to what you should do. Tanjiro or Muzanㅡ Gah! If you went after Muzan, then Tanjiro would be in trouble if he couldn't properly restrain the man. But if you were to go and assist Tanjiro instead, then the king of all demons would be able to escape and you wouldn't ever know when you guys would ever see the monstrosity again.

"Fuck it!" As you passed the male with the white fedora, you sent him an ominous look, making sure to swipe a finger towards him and project some of the embers produced by your quirk. Now assured that you changed the color of it to white so that even with the littlest amount, it would at least manage to harm him, you used your feet to run towards where the scene was the fastest you could. But with you using that blaze with the said color, you could already feel your energy depleting, making you run slower than you desired. You hated the vulnerability it came with once it had sucked out all of your strength.

"This won't be the last time that we'll be seeing you!" Shouted by you before finally focusing all of your attention unto your friend who needed your help. 

"Dear!" The woman shrieked as she couldn't bear watch what was happening to her lover. Tanjiro scolded her immediately before saying, "You need to worry about yourself!"

"Take a cloth, madam, and press it hard on your wound!" You instructed before grabbing the wrists of the man and pinning it down while Tanjiro placed all of his bodyweight down to the victim's lower half so he wouldn't be able to move no matter how hard he tries. 

'Muzan... that vile creature!' You kept cursing him again and again as you witnessed one of his works. How can someone stomach doing such an awful thing? Well, definitely that man. And seeing as he was the one who certainly wrecked havoc in the house of the Kamado's, the hatred that started burning inside of you grew wilder and wilder. You just hoped that your fire had hurt him majorly enough.

As Muzan started walking away, Tanjiro became aware of this fact. He was feeling quite conflicted. He wanted to end that demon's life right then and now but he couldn't just leave this man for you to handle all alone. "Muzan! I'm not letting you get away! No matter where you go! I'll follow you to the ends of hell and I swear I'll slice off your head with my blade! I'll never forgive you no matter what!" He turned his neck so that he would face the suited man's direction and bellowed the words with all of his might.

Meanwhile, Muzan was attempting to keep a calm facade as he held his daughter. He saw what you did and immediately right after you threw those, whay seemed to be fireballs, at him, he could already feel its its effects. The intensity of it was testing his ability to keep his cool. It was so excruciatingly painful that he knew if you were to throw those things at him larger in amounts, he might as well just stand under the rays of the sun. "Honey, are you alright?" This lowly being asked him. It looked like his composure was slowly cracking. "I'm fine. Let's just... get away here. My lovely daughter musn't see those horrendous things." 

"What the hell are you doing?!" The police officers questioned you two as they marched towards the two demon slayers. "Is it a drunk? Whatever it is, kid, step away from that man!"

"I can'tㅡ!"

One of them started to pull at Tanjiro's haori making irk marks appear on your head. "Hey, Tanjiro. I'll take care of these shitholes," you cracked your knuckles once he did what you've asked him to do, wondering what you were up to now. "Get out of our goddamn way you good-for-nothings!" You pulled back your clenched hands and punched the abdomen of the officer making him choke on his own spit and stagger because of the sheer force of your attack, his grasp on Tanjiro's clothes was now gone.

"Hey, little kids like you shouldn't attack grown-ups!" 

"Hah?! Haven't you lots understood it by now?! Only him and I can keep that person in check!" You dodged their hands that tried to restrain you, successfuly distracting them from Tanjiro who was holding the man down. Though, one of them redirected all of his attention back to Tanjiro, ready to hit him with his baton as he replaced the other officer awhile ago and was now the one pulling on Tanjiro instead. "Please stop! This person and other people as well will be in great danger if he were to be let loose!" The burgundy-haired male pleaded.

"I already beat the two of your co-workers senseless, and you still had the audacity to pull such a thing on my companion-" About to pounce on the man, stupefaction embedded itself within you once your eyes saw the patterns swirling around, knocking the policemen off of their feet.

Though that second of bewilderment morphed into alertness the moment your brain realizes that this might be an attack from a new enemy. 

"You two still use... the term 'person'..." The beautiful woman who donned a flowery kimono uttered once she entered your field of view along with Tanjiro's. Next to her was a boy with green hair, his eyes were glaring at you two, prompting you to think if that was his resting bitch face or something.

"To refer to even a transformed demon. And you two were trying to save him," she said with a kind look present in her pupil-less eyes. "Allow me, then, to lend you a hand," she continued.

"But why? Your scent... Your scent tells me." Tanjiro asked. You were still wary of them. Your reasons were justified as wellㅡ I mean, two people just appearing out of a blue... Who wouldn't be suspicious of that?! Plus, with Tanjiro's hanging sentence, you could only make the conclusion that they weren't as human as they seemed.

"I am... a demon, but I am also a doctor," she stated as she placed a hand on her chest. "And I wish to annihilate that man, Kibutsuji," she finally wrapped up.

.

.

A man in the shadows snapped his finger after his little killing spree. Two demons instantly were bowing down before him, ready to follow whatever orders were to be given to them. "Bring me the head of the Demon slayer who wears hanafuda-like earrings. Same goes with his h/c-haired companion, yet bring her back to me alive. Understood?" His eyes flitted towards them, his orbs glowing underneath the dim alleyway.

"As you wish."

"Your wish is our command."

They were gone as quick as they came. Muzan's body shook with an emotion akin to anger. He still couldn't forget the agonizing amount of pain that girl gave him. The pain only lasted for a short amount of time, but it was enough for him to feel the painful sensation brought by his skin singeing because of that girl's fire. What made him curious was that flame that enveloped her as a whole. She was a human, that much he was sure of, but she wasn't entirely normal either.

He could just imagine how much more powerful he'd be once that lass became a part of those under his control. She had power that rivalled those of the Upper Moons and that enough was a great feat for one to achieve.

Ah, yes. It wouldn't be long 'til she'd be in his grasps for him to use. It would only take a matter of time...
