The son of the demon king

Meeting the hashira

Tanjiro followed rui's scent, he could smell some people farther away from rui's location

"These demon slayer suck at finding these demons"

Then running tanjiro had quickly found rui next to a body of a sliced up demon slayer, tanjiro then charged forward and delivered a slash at rui who turns around and quickly dodges but did get cut on his neck

He quickly regenerate the small wound before looking at tanjiro who looks piss

"Another one? Why can't you just leave me and my family alone?"
"Well your family is dead, father would be glad that I got rid of another weakling"

Rui's eyes widen in shock, did he say that muzan was his father? No impossible. He was evilest person so him having a son is impossible to believe

"Your lying, the master wouldn't care for a weak human"
"The fuck did you just call me?"
"A weak human, the master would never waste his time with weak human"
".........ha......ahahahahahahaha! Now I have a better reason to kill you!"

Rui was going to attack but he saw tanjiro take a stance before muttering

"Moon breathing, third form: loathsome moon - chains......."

Then with a quick movement of his sword, tanjiro beheaded rui making him go wide eye seeing his eye sight on the ground and seeing is own body turn into ash

Unaware to tanjiro, giyuu and Shinobu watch in shock seeing tanjiro kill rui and lower moon do easily

"Who is that kid?"

Giyuu said with a bit of shock as Shinobu looks more shocked and mutters out

"H-his name is.......tanjiro kamodo......."
"How the did he do that? What rank is he?"
"The other demon slayers say he is a mizunoe, but they said he showed great fighting skills and abilities of a hashira........"
"We must take him back to HQ, the master would probably want to see him"

Shinobu nodded before walking up to tanjiro and tapping his shoulder

"Yahoo!"
"S-Shinobu! I see we met earlier then expect"

Tanjiro said rubbing his head with a embarrass smile, Shinobu found it cute

"Could you please come with us? We want to show the master your skills and abilities"
"Of course! Lead the way!"

Tanjiro was very excited to find HQ, his father was close to finding it but it kept well hidden so his father had to send some demons to scout the regions to find HQ

Shinobu giggled as she lead tanjiro to HQ, they had started to travel to HQ till dawn but unknown to anybody was that tanjiro had put a liquid on the bottom of his shoes so he could track the scent back to HQ

So unknown to the demon slayers they lead a spy back to HQ

Tanjiro was jumping from tree to tree and watching as Shinobu elegantly jumped

"S-so.......pretty......"

He thought and as fast as they ran, they had arrived at HQ. HQ was a big compound with several mansions belonging to the pillars and tanjiro noted the area had wisteria trees surrounding the walls of HQ

"Guess I've have to cut those down"

Then walking to a house, Shinobu stood in front of it with giyuu

"Um guys? Why are we standing here?"
"Because we are waiting for the other pillars, the master had called a meeting with you, tanjiro"

Tanjiro nodded, this couldn't have gotten any better, first he found HQ and now he found the masters location and tanjiro thought about plans of breaking in and killing everyone here in their sleep
