if Luffy got reincarnated in to the world of demon slayer

Prolouge

We can see Luffy sitting at the head of the Thousand Sunny when Sanji yelled
"COME AND GET YOUR DAMNED FOOD"
This caught Luffy off guard and went towards Sanji who still had the skin of a poisonous fish is sitting and Luffy ate it all yeah he got poisoned and went into a coma when he woke up he wasn't in the med bay but it looked like he was at...

A temple at night then he saw a boy with reddish hair and a greenish blue and black kimono and saw a girl with a piece of bamboo on her mouth kicking a guy's head completely off with it flying away but it looked like it was still alive the head grew arms and the boy swung at it with a hatchet the things hair wrapped around it and the boy threw the hatchet at a tree wich got it stuck and then ran towards the forest to run towards the girl but then Luffy went to the head and asked " Hey head what are u??"
"HEY KID GET THIS HATCHET OUT OF THE TREE" he yelled Luffy just looked questionable at the being and asked
"Why should I shouldn't u awnser my question fort then maybe I will help you."
The thing growled at Luffy and said
"I'm a demon kid now help me" Luffy looked and said "no" the demon Looked pissed and yelled "WHY NOT U STUPID BRAT" but Luffy was already walking towards the guy with the kimono in the forest

He saw the boy running towards the body to tackle it and run of the cliff Luffy saw this and ran and stretched his arm out like gumo gumo no mi pistol but without hitting him and instead grabbed his kimono he looked up and looked shocked at Luffy stretched arm but Luffy pulled him up

At the demon

Aghr did my body just die that fucking hurt

Back to Luffy and the boy

"H-huh how did u do that are you another demon" he said confused and scared
But Luffy awnsered and said " what's a demon? That head guy said he was a demon but I didn't know what he means."
The boy looked more confused but ran towards the girl to look if she's ok
Luffy came to and looked he said
"Looks like she's gotten pretty beat up."
The boy picked the girl up bridal style and put her in the basket with a blanket on top of it so she could rest they walked towards the demon and the boy tried to cut it but a man said in a blue kimono with white clouds on it
"That won't work u have to bash it's head in." And gave the boy a rock the boy hesitated but Luffy just went ahead and punched the demon Alot until u couldn't recognize it anymore and asked "Is this good mask guy?" He looked amazed how he did that with he's fists and said that it was enough he then told the boy if he was the one who a so called Tomioka
Told him about and he nodded fairly quickly we then started walking and Luffy asked where the girl was and the boy awnsered with "She is in the basket"
And Luffy was wondering why but he instead asked what all of they're names were the boy said "I'm Tanjiro Kamado
And the girl in the basket is my little sister Nezuko Kamado." The man with the mask said "My name Is Urokodaki"
Luffy looked amazed at they're names and said
"My name is Monkey D. Luffy!"
