Nezuko was confused and so was Tanjiro. Why was this demon friendly ? Why did he call the demon king by the Moon Breather hashira's name ? Why did he insult him ? Why was this voice familiar ?

"Nezuko, Tanjiro. You want to defeat him ? We are on your side. We also wish for Tsugikuni to be killed as soon as possible. Kiriya will wait for you near the noodle seller."

While the people around were still distracted by the weird pattern, the demon slayer took her brother's hand and left the scene. Nezuko got even more confused. "Kiriya" was a name she heard before but she couldn't recall when.

She walked to the place they left when Tanjiro smelled the one who murdered their family and saw the young girl with her purple kimono.

"Oh hello Mi-"

She got interrupted by Kiriya

"I'm a boy."

Nezuko started to question her sanity. He looked so much like a girl. Hair dressed like a girl's. Eyeliner. Woman obi. Feminine voice. And it was a boy ???

"I'm very sorry, sir. I won't do the same mistake again."

He didn't answer but looked at Tanjiro.

"You're aware he's a demon, right ? He seems pretty weak, though."

Wait... Weak... ? Was he calling her brother weak ? But Tanjiro wasn't...

"The hell are you talking about ??? Tanjiro was the strongest of all our siblings ! He used to carry charcoal to the village down the mountain almost everyday before he turned into a demon ! He could even help the villagers with some of their works when he had the time ! That's right ! That's our strong big brother! Our Tanjiro!"

Kiriya looked annoyed by Nezuko's statements but she didn't care and kept on rambling about how amazing her older brother was while following him through an alleyway. When she turned to see Tanjiro and then looked back at where the kid was he... had disappeared and there was no way he just walked away since they were in front of a dead end. She tried to see where he was but nothing.

Suddenly, the demon's head came out of the wall which scared the living shit out of Nezuko. He had an annoyed face and silently told the girl and her brother to follow him through the dead end. After seconds of hesitation, the siblings ended up doing as the crossdresser asked.

The feeling of going inside the wall surprisingly felt nice, a bit like being underwater but able to breathe. Sadly, that feeling didn't last long and stopped when the remaining Kamado's saw a big and rather modern house. It was very fascinating but Nezuko guessed it was either Kiriya or the older man's blood demon art that was hiding it all along.

The three of them then walked inside the house and saw the older demon preparing tea.

"Hello again, Nezuko and Tanjiro." He said with a calm and dreamy voice.

Tanjiro bowed down and after seeing her brother, Nezuko did the same.

Out of nowhere, the Kamado boy asked "Who are... y- you... Sir ?"

Nezuko still wasn't used to hear her brother's voice since he was kind of asleep for two whole years.

The oldest answered "My name is Kagaya. As you have seen, I am a demon but I've been able to break from Tsugikuni's curse. Just like you Tanjiro." He turned to Nezuko "You may be wondering how I know your names. Well I've been looking to get in contact with you two for a three years, now."

And at that moment, the girl remembered. Those two demons. Kagaya and Kiriya... They were the intruders she heard that one night when Mr Tsugikuni left for work. It made her think for a moment before asking "Excuse me, sir but... My master... The one who taught me how to become a slayer... His last name is the same as the demon king's... Why is that...?"

Kagaya gently smiled "Sadly, this question... It is not my duty to answer it. You should ask that next time you see him."

Nezuko was a little confused of why he would say that but thought there must be a good reason for it.

Kiriya then served tea to the girl and Kagaya. The fact he and Tanjiro didn't get any surprised Nezuko before she remembered demons probably couldn't drink tea like humans do... Then how was the oldest of them able to... Oh well it wasn't important, there were way more important questions to ask right now.

"I apologize if I'm asking too many questions but... Why did you want Tanjiro and I to see you...?" She asked, unsure.

Kagaya sipped on the tea without grimacing contrary to what Nezuko thought it would d happen.

"I have heard of your wish to turn this boy -he looked at Tanjiro- back into a human... It might not be as impossible as you might think... I don't know exactly how to make this but we might get closer to make an antidote soon."

Nezuko's eyes widen at the word. Really? Could her older brother be able to run happily under the sun and without any wish of eating human flesh ? Then the word "happily" reminded her that Tanjiro wasn't really at the moment, if we think about what happened recently... She tried not to think about it for a while but she didn't react in the best way... But anyway, the medicine ?

"Really? You will be able to help Tanjiro?" she asked with visible excitement and happiness.

Kagaya shook his head up and down before he opened his mouth again "But for that, I will need your help with some things...

-Anything, sir !

-Does it bother you if I get some of your brother's blood as well as yours ?"

Nezuko turned to Tanjiro to get his approval, which she got with a simple nod of his. She then looked at the man "Anything more, sir ?"

He hesitated before answering "I would need the blood of one of the twelve kizuki... Since they have more of Tsugikuni's blood, it might be useful... But beware, young girl, they are the best demons he has so it will be extremely hard to beat even a single one."

Nezuko opened her mouth to tell him about how far she would go to save her brother before a giant rock went threw the wall and decapitated Kiriya. The girl ran to check on him as he was already regaining strength.

Kagaya left the room quickly, taking Tanjiro's hand. What the hell was happening? The demon slayer was sweating and breathing heavily. Well her sweat was cold. She couldn't help but shake. Had some powerful demon found them? Were the boys going to be okay.

She helped Kiriya leave the room too as his head was still regenerating. More rocks started to fly threw the walls, hurting all the demons in the room.

Then everything stopped. No one moved, maybe they would leave thinking they wrongly killed a human family? At least, that's what Nezuko hoped for. This demon seemed quite strong and, not to sound narcissistic or anything, she didn't want to die ! It was better if she didn't risk her life, right?

Suddenly, she, and the others, heard someone screaming. Followed by another voice ? Oh shit they were two then ? It made Nezuko want to leave her huding place even less.

Silence again after the two demons had a whole argument. Then a blinding light could be seen, followed by a thunder sound. Was a storm starting? No, it wasn't natural at all-

The demon slayer then slowly unsheathed her katana, understanding she really had to fight those guys.

She sttod up, got back to the other room and saw how destroyed it was. Behind all the dust, she could see the destroyed walls and torn up rugs. She tried to look further and couldn't distinguish anything before a long while.

What she noticed when the wind made the dust go were two blue glowing eyes. Then appeared the body, muscular man with wild boar tusks, what an ugly sight.

She tried to find the second demon quickly and noticed a blond man with his eyes closed an orange kimono. He smirked at her.

"Oh, such pretty face for a demon slayer! Would you like to become my lunch right now and have the honor to be eaten by one of the twelve kizuki ?" the blond said with a surprisingly loving voice.

But ugh. No way she'd let herself be eaten that easily... Wait did he say he was one of the twelve kizuki ???
