Creation- Demon slayer fanfic

Chapter 24

It was early in the morning when Rei woke up, rubbing her eyes. She yawns and then notices me, sitting in the exact spot I was when she fell asleep.

" Did you sleep well?" she asks.

" Didn't sleep. We should go, I smell a demon," I answer curtly.

She stretches and grabs her katana as she stands up.

" Next time I'll be the lookout, you sleep!" She offers cheerfully.

I shake my head in disagreement and start towards the scent. It's gotten weaker since the wind shifted, but I can still track it. Hopefully this mission will go smoothly, though I could do with Rei dying when we fight the first demon. I prefer to work alone since my breathing style is very brutal. It's destructive and I don't have too much control over the newer forms just yet. Although, I may not need to use it if the demon is weak enough. That would be ideal, since I have to work with...her.

Shooting an annoyed glance at her, I shove my hands into my pockets and pick up my speed.

" We're gonna kill this demon so easily!" Rei says optimistically.

Does she even know that this mission is to eradicate the lower moons? This demon is most likely one of higher rank since it's scent is different than most.

" I heard that you're super strong and your breathing technique is very dangerous! That must be so cool! Most of the forms in my breathing technique are slashes, but apparently you can manipulate your own blood so your forms are never the same attack!"

That's a lot of words coming from such a small person. 

" Fighting long battles must be easier since the demons will never know what comes at them! Even though you don't have as high endurance..."

I snap my head towards her, infuriated.

" My breathing technique isn't good when working with someone else. I'll kill them if they get in they way. Don't say I don't have high endurance, I can smell you don't either, shorty," I retort.

I already dislike this person and she isn't making it easier on herself.

" Hey! Don't call me short Aku! That's rude!"

I roll my eyes. She was just rude to me!

" At least I'm taller than Shinobu," she pouts.

The scent is getting stronger and I speed up my pace once again. A metallic smell is mixed in with the demon's. 

" There's blood," I whisper, taking my hands out of my pockets.

" Uh oh..." Rei trails off.

I climb into the trees since we're getting closer. Slowing my breathing and heartbeat so my scent is less prominent.

" Stay here, wait for me to come back," I whisper as I jump to the next tree.

I go from tree to tree, the leaves rustling quietly as the scent gets more potent. I arrive at the side of a hill, one which has a hole in it. I remember Kagaya saying the demon is located in a cave. This could very well be it...

I get as close as I can without exposing that I'm present at it's home. The sun beats down on me through the leaves, meaning the demon can't come out just yet. We should fight it while it's day so we can evacuate outside if we need to.

A sudden loud screech echoes from the darkness, causing me to lose my balance and almost fall. My ears ring loudly as I cover them. The warm scent of blood followed the noise.

Retreating back through the trees, I spot Rei waiting patiently for me.

" So?" She whispers excited.

" There's a demon alright..." I trail off.
