Demon Tanjiro & Slayer Zenitsu (Zentan)

Frist Meet

(Their hashiras in this AU! There all 18 and above also.)

Zentisu pov-

I got called to another mission a lot lately since I became a hashira they have been sending me on these crazy missions! By now I think there trying to kill me. The crow told me to go to Mt. Kumotori the west side right? So far I've seen nothing all I have been doing is following this trail that leads somewhere. I start to pick up the pace since its getting colder and I need to find shelter. 

After a while of walking a came across a house. But there was blood everywhere a drew my sword as I could hear the heart of demon and a human. Someone was still alive I need to hurry before the demon kills them!

I rushed inside to see a demon crying over a pill of dead bodys. Holding a young girl in his arms. The demon looked over at me with bright red eyes. "Please you have to help me! My sister shes dying please take her!" The demon yelled holding his sister in his hands standing. She was still alive so he was right about her dying but why isn't he trying to eat her.

I didn't know what to do I was frozen all I did was just stand there. "You have to do something please she's the only one alive! The rest of my family is dead please save Nezko please!" The demon was now on his knees begging. 

"Ok I'll take her but if you try anything I'll cut your head off." I said putting my sword away and picking up the girl. The demon was still on his knees crying. I ran off to the village to get her some help.

Why didn't I kill that demon? I mean his whole family is dead expect his sister but he had to of kill them. But he didn't have any blood on his mouth at all so he couldn't of killed them to eat them. His heart beat didn't sound like a normal demon earthier who is that guy?

~Time skip~

The girl was now in the village getting taken care of. She was a very pretty girl to maybe she'll marry me for saving her. Then I'll have a wife and shove it in Tengan face that my wife is prettier than his 3 wifes.

I should go back and slay that demon thats what I came here to do after all. I started to run up the mountain again once I reached the house again. I couldn't hear the demon anymore he was gone. But it looked like he buried his family before he left. 

There where foot prints in the snow heading down the mountain throw the woods. I decided to follow them it was almost sun rise if that demon was out here any long he'll die from the sun for sure. Running may be my best option right now.   

The foot step went down the mountain and into a cave. The sun was now up and the snow was melting and there was now a cave in front of me now. The demon must be inside I can hear his heartbeat.
