STARTING EPISODE

You are currently on a mission. your crow has been guiding you through the crowded streets but now it's almost midnight, and all the people have gone to their homes. As you are walking, you sense a presence of a demon....no..three demons?...

-you saw two boys running towards the demon you were sensing.

"Huh?" You're shocked as you thought what is a kid doing out at the night?

"..What are they doing here?..Are they stupid enough to run around like this at night?!"..Your grip tightened on your katana.

-you sigh- And started running towards them.

as you continued running-

'how is he so fast??' you thought.

Then your eyes widened as you see that he is fighting with three demons.

"HEY!!" You shouted and ran towards them.

The boy looked at you shocked but then he saw your uniform.

"Are you alright??" you shouted

"I am fine!! But be careful! This demons can go through walls and roads!" He shouted back.

As he was distracted, the demons took the chance and attacked him from the back....But then suddenly a girl with a bamboo muzzle came out from the box and kicked him in his (demon) head.

"Nezuko!!?" he said surprised.

-shocked-...'s-she is ..a demon'...you thought.

"Nezuko! Nezuko are you alright??" He asked at the girl.

"Mhm!" The with the muzzle answered.

'wth is going on??' you thought.

"HEY! Don't get distracted during fight!" you shouted at him.

"Y-Yes!" he nodded.

- AFTER DEFEATING THE DEMON-

(You will know your skill as the episodes continue)

-You breath heavily-..

"hey..are you alright?" The boy asked.

"I am fine...what about you?"...You asked looking at him.

"Me too!"...he said.

"Anyways! I am YN! Nice to meet you!" you said excitedly.

"I am Tanjiro! Nice to me you too!" he answered matching your excitement.

"I wanted to ask something..Tanjiro"..You said.

"What is it?" he asked confusingly.

"That girl...(pointing at The girl) ..she is a demon right?"...you said.

-shocked and sad-..."Y-yea...but she is my sister! And she is good! She never ate human!"

...-you did not respond-

Your grip tightened on your katana your holding.

"The sun's going to rise...you should take her somewhere else"...you said looking down..

"Your right.." Tanjiro responded

"well then...see you next time!" You said.

"Yea! Sure! Bye".Tanjiro replied.

-Then Tanjiro took his sister inside a wooden box and went to the guy from earlier with whom he was running with and was saying something to him. You did not pay attention and left from there with your crow.

For context: You are the youngest siblings among shinazugawa family. ( After their other siblings d*ed) And they don't know you became a demon slayer corpse. Genya nor Sanemi knows about it.
