The creature form a far. {KNY OC}

'Mom'

I quickly grew attached to M!Y/N and F!Y/N, they were kind..and I want to protect them with my life..I just worry that I can be able to protect them, but..they know about me..they know what I am and still stayed with me..I would've expected them to curse me out and leave, but they didn't! They..they were amazed at my other form

I had been teaching then my language as they have taught me theirs

I learned quickly and surprisingly they learned my language fast too, we used my language for the most part, it was fun, whenever we had to discuss something in secret around someone we used my language

-Time skip! 2 weeks later!!-

I was walking with M!Y/n, he chatted away as F!Y/n slept as I carried her on my back

"And! I've always wanted to be a demon slayer!! I just never got to train" he rambled

"Well, I don't know demon slayer training. But! I do know some training from where I'm from! I can teach you some, and we can find you a proper trainer!" I smile

He beams

"M!Y/N..I want you to know..it is likely I won't always be around..so..if you two are ever in danger while I'm away please call out the my name .." I say

"Okay?" He says

I smile softly

We were walking for a while but we found a small inn, so we got a room. M!Y/n and F!Y/n went to sleep immediately i stayed up to watch

I could sense another presence..but..it was no human presence..well, it may have been? I think there's two people.. a demon and possibly a slayer..

"Shit.." I mumble

"Sayomi? What's wrong?" F!Y/n asks

I looked over to her, she barely woke up, can't blame her she slept earlier

"There's some people nearby..I should go check it out..if someone comes in and if they try to hurt you..yell out my name, okay?" I tell her

She nods her head

I get up and slowly walk to the door

"I'll be back okay, if you brother asks tell him I went to go explore." I tell her

"Okay.." she says

I exited the room, and followed the presence..it grew stronger the closer I got to the outside

When I got outside I saw a demon..not like the ones I saw before, this one was weak..and there was that same pink and green haired woman. I snuck over into the trees.. the demons eyes read something.. 'lower two'

The battle seemed interesting..and I could tell the woman held back to not destroy the inn nearby

Should I help her? If she's a demon slayer I could ask about training for M!y/n and even F!Y/n if she wants to

I was going to walk away when I saw F!Y/n and M!y/n walk out, my heart sunk when the demon saw them..

With the blink of an eye it held both by the throat

"I-If you let me go I let these two live!" It smirks

"SAYOMI!!!!!" I they called, tears swelling up

I jumped from the branch I sat on, my hand extended

I grabbed the demons head and slammed it into the ground, as I did it released M!Y/n and F!Y/n

I managed to catch them before they hit the ground

"Listen to me, go back to the room! I'll be there soon okay!" I told them keeping eyes on the demon

"O-okay!" M!Y/n said grabbing his sisters hand and rushing back to the room

I pulled the demon by its hair

"GAH!" It screamed

{Mitsuri's POV}

I froze once the lower moon grabbed the kids..

"I-If you let me go I let these two live!" It smirked

I saw tears in the kids eyes

"$A¥0M¡!!!" They yelled
(The white spike language is of course not know by any human aside from M!Y/n and F!Y/n, so when hearing the languages from another pov it will look like this!)

I-I don't know that language, I've never heard-

A woman appeared from nowhere, she slammed the demons head into the ground

It released the kids who fell backwards, but the woman caught them

"Listen to me, go back to the room! I'll be there soon okay!" She tells them, they must be foreigners, and she knows Japanese?

"O-okay!" The male says before grabbing the girl and rushing off

Then the woman grabbed the lower moon by it hair

"GAH!" It screamed

I watched in horror as she tore it apart..no hint of mercy at all..it was so..gruesome..she tore him limb from limb and the demon tried to scream..but she shoved its face into the ground preventing the noise from exiting his mouth

Then, she pulled out a small knife, and cut off its head.

"W-Who are you?" I ask

"Hmm? Oh.. Sayomi..you are a demon slayer right?" She says

"I am! Are you one! You should be one!!" I beam.. this woman would be a huge help

"Oh, I'm not..but I guess I could be one..but I want to train my so- M!Y/n.. to be a slayer.." she says pausing

"Awww!!!! I can see if I can train him!!! Maybe someone can train you!!! You should totally come with me!!" I squealed

She softer at me a bit..she was so tense before..maybe my energy?

"Okay..we can go with you.." she says

I beam

"KYAAAAA you're so cute!!!! And so are you kids!!" I squealed

"K-kids?" She asks

"Huh? Yeah, your kids? The two kids!" I say

"Oh, no they aren't my kids, I'm simply taking care of them." She explains

Oh..that would've been so cute! Plus they seem so attached to her and she seems very protective!

"Okay then..I guess get them and we can head to the Headquarters.." I sigh

She nods her head and rushed back to the inn

{Sayomi's POV}

I rushed into the inn, and back to our room, M!Y/n and F!Y/n sat at the far corner of the room

Once they saw me they perked up, and ran over to me

"MOM!!" They yelled as they crashed into me and pulled me in for a hug

"M-mom?" I ask

They nodded their heads..tears streaming down their faces and they hugged tighter

I smiled softly... and rapped my arms around them..

"Okay dears, you can call me that.." I say

Soon, M!Y/n fell asleep..I picked him up and held
F!Y/n's hand, we walked outside back to the pink and green haired woman
